Customer Ratings & Reviews

I've been using the GoTrax Z4 Pro Foldable Ebike for my daily commute, and it’s been fantastic. Here’s my experience: Quick and Easy Setup: Installing this bike was a breeze. I only had to adjust the brakes a bit, but there are plenty of how-to videos on YouTube if you need help. Comfortable Ride: The ride is smooth and comfortable. I use it to commute to work, which is about 10 miles away. Google Maps estimated it would take 1 hour and 10 minutes by bike, but I consistently make the trip in 40-45 minutes, even without using the pedal assist. I mostly rely on the throttle and hit a max speed of 20 MPH. When I use the pedal assist, I've reached speeds up to 30 MPH. However, I find 20 MPH is perfect for city riding—fast enough to get around quickly but safe enough to brake suddenly if needed. When I get to work, I charge the battery. Reliability and Freedom: This bike is incredibly reliable. It gives me the freedom to go wherever I need without depending on public transportation. Plus, I save on vehicle insurance, tolls, and other expenses that come with owning a car or motorcycle. Pros: High top speed of 28 MPH Long range of up to 50 miles Easy to fold and store Comfortable and smooth ride Saves time and money Cons: A bit heavy when folded Overall, I love the GoTrax Z4 Pro for its reliability and convenience. I highly recommend it to anyone looking for a great ebike! Design: The foldable design is super convenient for storing in tight spaces. The black finish is sleek and modern. Battery Life: The battery life is impressive, allowing for multiple long rides. Comfort: The ride is smooth and comfortable, with adjustable handlebars and a well-padded seat. Ease of Use: Assembly was easy, and the controls are intuitive. Value: Excellent value for the features and performance it offers. Pros: High top speed Long range Convenient foldable design Stylish look Comfortable ride Cons: A bit heavy when folded Overall, I’m extremely satisfied with the GoTrax Z4 Pro. Highly recommended!

Not the easiest to put together as directions are not much to go by. Make sure you put the fender on with light first. Then go for front wheel. My front rotor was scaping the brake pads. Had to readjust and finally pull the rotor out more. Customer Service isn't good and no one gets back to you till 72 hours via email. No one on phone can help either. No FAQ on website as stated in email from response. If you are under 5'2 this still will be a big bike for you. Plus handle bars don't lower for shorter people either. I had to loosen screws and tilt handles down. It take 2 people to get out of box and flip bike over to attach front wheel. Very heavy bike. It does NOT go 28 MPH. Top speed with just thumb throttle is 19. Only one sprocket for gears so you end up using the highest anyway. Other than a long set up time and help moving it, the jury is out for now. Rode 5 miles tonight to get use to.

This mode of transportation is incredibly convenient for daily commutes to work. It's designed for effortless assembly, allowing you to set it up quickly and without any hassle. Once assembled, it provides a nimble and efficient way to navigate through busy streets, making getting around a breeze. Whether you're weaving through traffic or making quick stops, it meets the demands of a hectic schedule with ease.

I'm absolutely loving my new electric bike! The pedal assist feature has made my daily commute a breeze, and the battery life is impressive. The bike itself is sturdy and well-built, with a comfortable seat and smooth gears. The electric motor is quiet and powerful, making hills a thing of the past. Plus, it's great for the environment and my wallet - no more parking fees or gas money! Overall, I highly recommend this e-bike to anyone looking for a fun, convenient, and sustainable way to get around.

Would give it five stars but the front tire has been losing air from day 1. I have to figure out if geek squad is going to fix it or if I have to pay out of pocket. Other than that issue it is really nice, it was much nicer in person than the pictures portray. I got it for my son and he loves it, says it’s very fast. Overall I think it was a good purchase.

Quality is good, The manual says it runs at 28 miles per hour but it will only reach that speed with assistance not just with the accelerator so if you want to run at that speed you have to pedal a little. The highest speed WITHOUT assistance will be 19 miles per hour.

Amazing experience, The staff in corporate office who resolve problems are the best . I had purchase a bike and the geek technician cancelled my appointment due to retail association putting in the wrong information.. I contacted Best Buy Corporate office I was so amazed how they talk me into buying the bike again and they listened to the part I was upset with retail sales person. But corporate handle the issue very personally. I’m enjoying my new bike

This eBike offers great value by packing in all the features I wanted, including being able to fold it and put it in a car! My Perspective I used to do a lot of biking, recreational but more intense than most recreational bikers around where I lived at least. I did biking on a lot of hills, narrow paths, on road, up and down steps, and mountain biking. Since then, I don't bike often and not as rough as I used to. It was something fun for me to do and a great way to get exercise but rarely a mode of transportation. This eBike is really a game changer for me. I had to run an errand across town, into the city. I never would have considered using my other bike for that. It would have taken longer and I'm too out of shape to have done it in a reasonable amount of time without being exhausted. I had to go mow a lawn at a house I'm working on and try to get back home before the rain started. I thought I'd give the Z4 Pro a try. This worked great! I was able to use the eBike pedal assist almost the whole way, only a very short time of throttle. I biked over, mowed the lawn, and biked home. It was not dark but starting to get dark so I was very glad to turn on the front headlight and I have a red light on the back of my helmet so I felt safe. You may be thinking that eBikes make it too easy and you will not get enough exercise with it, but for me, I'm finding it enables me to get much more exercise than I would driving for shorter commutes that were still too far for my conventional bike. So again, to me, this is a game changer and I'm very excited to have the GoTrax Z4 Pro! Design It has what seems to be a pretty common eBike look but I don't mind that at all. I think it looks cool with the black and green. The small diameter tires help it to fit in a small place - see the picture I have of it in the middle of my minivan. It has a good sized black and white LCD screen that's very easy to see in day light or in the dark with the backlight on. There's a headlight too which goes on or off with the LCD screen backlight. There's an indicator on the screen to show you if the headlight/backlight is on in case you can't tell in light. The handle grips are awesome! Maybe they're common but I never had ones like this. They kind of have a build in plam rest and are really comfortable for me to use. There is front suspension but if you don't like it you can lock it so it's rigid. I like the suspension and haven't done enough road only button that I really wanted to use it with the suspension locked. The back has a generously sized storage rack mounted over the back tire. The pedals even fold to take up less room when folding the bike, but they feel strong and are not loose in any way when riding. The seat is very comfortable and easy to adjust the height of for different riders with the quick release mechanism. There are seven gears, one front sprocket and front and back disc breaks. There are 5 levesls of pedal assist. There is an handle where the seat post meets the bike frame that makes the bike easy to carry, I mean, it's 66 pounds but this makes it as easy to carry as it can be, I think, and very manageable for me. I never had a bike with fat tires before. It's a different feel but so far I like it. eBike Modes There are not really separate modes that you need to put it in, though if you have it on a pedal assist setting of Zero, you can't use the throttle or the pedal assist. If it's set on 1-5, when you peddle, the motor will kick in after about one rotation of the pedal. You can also then push the throttle down to have the motor go without any assistance from you. It has another low speed mode that I've only tested a few times. You hold down the "-" button and the motor will move the bike without you peddling at 3 to 4 MPH until you release the "-". I think it could be helpful when you're moving through a part of a trail that's more crowded but I haven't used it other than just testing it so far. As mentioned above, the max throttle speed (speed without you peddling) is 20 MPH. That can be reduced 10 MPH, I think. The peddle assist defaults to a max of 20 MPH as well but this can be adjusted up to about 28 MPH - keep in mind you must be peddling to reach that speed, but the bike helps a lot! At least one trail near me has an eBike max speed of 20 MPH, and it's pedal assist only, so you may want to think before bumping this up to 28 MPH and be aware of the rules where you are biking and then don't use throttle. At least be familiar with how to change it back to 20 MPH if you change it to 28 MPH. I do find myself changing the pedal assist between 1-5 as a ride because there is a big difference in the boost they give and depending on where you are, you will want less or more of a boost. The assist really can make most hills almost effortless, and you can always go to zero if you want it to pedal like it's a normal bike. Controls The controls are easy to use. I like the gear shift system. It's indexed so you can easily click through gears by moving the lever in one direction and simply pushing a button in the other direction. Changing the pedal assist power is simple as well, with a plus and a minus to take you between 0, for no pedal assist, up to 5, for the most pedal assist. There is Mode button as well and that changes the screen between showing current, average, and max speed as well as odometer, trip 1, and trip 2 distance. There is no time tracking on it, which would have been nice but if I had to pick I'd take the speed and distance trackers. There is a separate lever you press down for the throttle. Again, you need to have the pedal assist above 0 for this to work but then, just push it down at any time and the bike will go. Folding the Bike The bike folds fairly easily though it takes time to get used to how you need to move it and the best ways to hold it to do so. If I fold it up, it fits easily into the middle of my minivan, I took out one of the two center chairs and it fits right in there so I don't even need to stick it in the back. I tried putting it in the hatchback of my car and it didn't fit in there easily. It could fit on its side but I was trying to put it in upright and couldn't find a graceful way to make that work. If this is important make sure you check measurements of your vehicle. There is small stand just below the level of the front sprocket so that never hits the ground. If you turn the front tire parallel to the back when folded, it easily stands upright. The fact that this bike folds is great feature! I wish all bikes could fold like this. It makes it much easier to store and transport. I've included a picture of it in my minivan so you can see how easily it fits in there. Battery Life I think the battery life is excellent! I've been using it here and there for a week, gone 21 miles, used throttle and pedal assist at max speeds a number of times, and it's still at about 25% to 33% battery life from the first time I charged it! They claim 50 mile battery life and I think that's totally possible. It's probably pedal assist and not a max speed the hole time. Regardless, I'm thrilled that since I'm not usually biking very far, it seems if I charge it here and there I'll never need to worry about the battery. You can charge the battery while it's locked in the frame or take the battery out by folding the frame and unlocking the battery and then charge the battery separate from the bike. I'm sure that also means you could buy additional batteries and have them ready, just strap it to the storage rack over the back tire. In Summary I think if more people tried an eBike they would go out and buy one. It's such a great mix of something that can be very helpful and practical but also a way to get help you may need as you're trying to exercise. It's also just fun to bike on the thing! I also love seeing my max speed and how far I went. I'm not sure I care, but there is no cell phone/app connectivity to sync speed or distance info, or anything like that. The key needs to be in to use the motor, which is fine and probably good, but the key hole is in a very inconvenient spot. At least it's not in a spot where it's likely to hurt you in an accident, which is probably what they were going for. I do wish the display/trip computer had a clock and tracked the time but I love that the display is large and easy to read while riding in daylight or the dark. The manual is a bit odd and hard to interpret at times. Look over it, then just try the bike, it's easy to use, and then go back to the manual to clear things up more, and that should work fine. As an example, the manual refers to the pedal assist settings of 0-5 as gears, though the pedal assist does not change gears and is completely independent of the bike gears 1-7. Overall the manual isn't bad and does have color pictures which can be very helpful. Some eBikes offer no throttle or only throttle and have no pedals. I'm very glad for all the options the GoTrax Z4 Pro provides and think it's a great overall eBike package and value!

This is my 1st eBike, and i love it. I've done some research via YouTube reviews and never this exact bike review, but I have found its sister models F2 & F3. Seam, this is another Bestbuy exclusive. What i can say it it's much like an upgrade version with the bike rack and upgraded tires. Love the battery range and pedal assist. The bike assembly was challenging, getting front brake calipers from making noise and due to lack of instructions. If this is your 1st bike like me, I would suggest getting professional assembly and tune-up.

Setup was relatively straightforward. While I have experience assembling bikes, I would say the included directions make it simple enough for anyone to do. Assembly consisted of attaching the front wheel, fender, light, saddle, and handlebars. There is a setup guide with clear instructions/photos and all of the tools needed to set it up are included. The build quality of the bike is great. It feels sturdy and durable. I was pleasantly surprised with how light the bike is considering how heavy e-bikes tend to be. Components-wise, there is a mix of name brand (Shimano) and non-name brand parts. I found there to be low clearance on the back wheel fender; it hasn’t been an issue thus far but will be something I continue to monitor. After I figured out how to do it, battery installation was intuitive and worked well. Tip: on the drive side of the bike there is a metal cylinder; that is the mechanism that holds the battery in the top tube. So if you’re struggling to unlock it try to pay attention to the position of the cylinder. Likewise, the battery is “engaged” when the keys won’t pull out of the battery. Battery charging was super simple; the charger has an indicator light on it that turns green when fully charged. It can be charged while installed in the bike or on its own which is also a convenient feature. This bike folds really easily and gets really compact. Moving bikes like this can be a hassle so it’s really nice to only have to focus on the weight and not the shape when moving it. It was still a challenge for me to load it into the back of an SUV. One thing to be aware of if you live in a place with high theft is that the folding mechanism makes it easy for certain components to be stolen (specifically the saddle and handlebars). Both the saddle and handlebars are on a quick release mechanisms which would make me not feel comfortable leaving it at a rack unattended. The bike goes up to 20mph comfortably in pedal assist and throttle mode. The acceleration on the highest assist setting is really fast; fast enough that I can feel it pulling me forward. The pedal assist works well enough but I found it to be slow to kick on and off. The throttle works well. I definitely see myself using both depending on the situation. The suspension makes traversal over rough terrain easy and smooth, and it has a lockout mechanism if you aren’t using the suspension and want to save energy. Likewise, the thick knobby tires add additional shock absorption and increases traction. The claimed range was 50 miles but I think based on how quickly I was burning through the battery it can be less depending on how you ride the bike. Overall this is a great introductory electric bike that has all of the necessary features of an e-bike.

I never owned or looked into an E-Bike until this thing arrived. It has been so much fun in the week I have owned it. The Instructions that come with it are simple and easy. It takes roughly 20-30 minutes to set up. Just be aware there are a lot of zip-ties and foam. I was extremely excited to try this out. So I plugged the battery in and waited until the next day to ride it. Man, was it worth the wait. I was used to riding regular bikes. This E-Bike easily conquers hills. The throttle is simple to push and easy to get used to. The fat-boy tires do a good job of keeping traction. The seat is okay and can become uncomfortable after long periods of riding. The first day I rode 24 miles. I wasn't originally going to ride it that much but it was so much fun. There were some noises and creaks when I was riding. So I went back home and got my Milwaukee Impact and tightened everything down. This solved a lot of the noise. The pedals that came with the E-Bike are hot garbage... I changed those out before I rode it. They just felt flimsy to me. I also changed out the handlebars to ones I prefer with extra grip. My back disk brake was over-tightened and I had to loosen the screw to center the back brake better. Today, my screen froze up on me which I wasn't sure why so I had to unplug the key and plug it back in and it worked. I have 100 miles on the e-bike. I'm 6'5 roughly 195 lbs. I have been averaging 25 miles before the battery dies. You may think you have to constantly hit the throttle. This is what I did the first time riding. This will drain the battery faster. I did find the pedal-assist to be the sweet spot. It does take some load off your legs when doing so. It kicks in about 1.5 seconds after you start pedaling. For 98% of the time I kept it in Pedal-Assist 1. Which will maintain a decent speed of 19 mph. When going downhill I bump the pedal assist up to 5 and can easily reach the max speed. The top speed I have hit going downhill was 32 mph. When riding this e-bike man do people stare. When the motor is going in pedal-assist it sounds like a wind chime. It has good acceleration as well. Overall, for a first E-Bike, this is a great option. Just know the battery only lasts me about 2 hours before it gets to 20%. Which is fine for me. Charge times are very accurate also. Pros Foldable Price is Competitive Pedal Assist is amazing You can buy backup batteries on their website Fat-Boy tires The screen is big enough to see Cons Pedals are Hot Garbage Weight Disk Brakes need to be cleaned regularly The seat slightly moves even though it is tightened down Not getting 50-mile usage unless you are maybe 100 pounds?

Great bike great exercise that’s awesome. I wish I would’ve got one of these a while ago but now that I got it I think I’m just happy.

The GoTrax Z4 Pro has a powerful 500-watt rear hub motor that can reach speeds of up to 20 mph. It also has a 48-volt lithium-ion battery that can last for up to 50 miles. This means you can ride for a good while and not have to worry about running out of battery. Another cool feature is that the Z4 Pro has a foldable frame. This means you can easily store and transport the e-bike (and its great from those that live in apartments where space is tight). The bike also has a rear storage rack for storing or transporting your items. Really cool! Putting the bike together took me around 30 minutes or so. It was not overly difficult but do make sure you look at the pictures as it helps when putting everything together. All I had to put on was the front wheel, seat, petals, front fender, and light. The handlebar was an easy “slide” on step. The display is clear, easy to read, and big. Overall, I was up and riding within 45 minutes, and it was a blast to use. The fat tires are nice, and the ride was smooth. I had zero issues overall and thoroughly enjoyed the rides I have taken.

It's a very good bike,i'm so happy buy Gotrak,very good deal

This is the worst Ebike on the market they the description says that this bike goes up to 50 miles , but actually it only goes 20-25 per charge contacted them they took 72 hours to respnd and they told me that the bike only goes 40 so i decided to return , when i returned they took a $160 for restocking and it is required but in these situation when they list a wrong information and wrong description for there bike they have to be rated like that never use gotrax and also the backlight doesnt work its just a sample of break that doesnt turn on .

I have 500 miles on it so far and its been awsome. I commute from work to home Every Day.

I just bought it and already have a flat tire. Including the bearings started falling off. Poor designed. FALSE ADVERTISEMENT DONT FALL FOR IT!!!!

This is my first ebike and I’m very excited to be able to review the GoTrax Z4 Pro! It’s also been a while since I’ve ridden a bike, but the Z4 Pro was a great way to get back into bike riding. Well, let’s get to my overall impressions and the pros and cons of the GoTrax Z4 Pro. Overall Impressions: The GoTrax Z4 Pro ebike is a great option for those looking for a reliable and relatively affordable electric bike. It has a comfortable seat and great shocks that make for a smooth riding experience. The 500-watt motor will let the Z4 Pro reach speeds of 20MPH and a range of 50 miles on a single charge. These features along with the ability to fold in half make the Z4 Pro a very versatile option for the ebike. The pedal assist has several settings that when accompanied by its 7 speeds will definitely allow almost anyone to ride this bike, even those who haven’t ridden in a long while, like me. The throttle control lets you just cruise by using the motor exclusively but will drain the battery at a much faster rate. The 50-mile range is more than likely when using the pedal assist as I was able to drain the battery by zooming around full throttle in just under 4 miles. Pros: Relatively affordable for an ebike Comfortable riding experience Can reach speeds of up to 20 mph Battery life lasts for up to 50 miles on one charge Cons: The bike is relatively heavy, making it difficult to carry upstairs or store in small spaces The bike doesn’t have much storage space, but there is a rack you can utilize in the fear The bike is not as fast as some other ebikes on the market This bike is a no-nonsense, easy-to-assemble, and foldable ebike with plenty of features that will help you get from point A to point B without any fuss. I wouldn’t hesitate to recommend the Z4 Pro to anyone looking for a versatile ebike.

As the price of gas continues to fluctuate, vehicle ownership skyrocketed thanks to the pandemic this left many seeking a viable alternative form of transportation. Electric bikes have been around for sometime but it is not until recent that they have become popular. I too found myself seeking out an easier way to get around without incurring massive debt. The solution to that problem that I found is the GoTrax Z4 Pro. It is a rugged e-bike that is rugged, easy & fun to use. :::Initial Impressions::: Upon receiving this it was obvious that this would take a little time to assemble, the box was roughly 85lbs. So, if you are unable to lift or push more than 50lbs please obtain help moving and setting this up. At first it may seem like there is a whole lot to assemble but that is not the case. You put together a few parts with the included toolkit and you are almost ready to go. I like how sturdy this bike is. It is not cheap looking or feeling. The paint job is good and the bike is partially assembled but done so in a professional manner and that is apparent by just looking at it. The tires are oversized and the bike sits low to the ground which means you can go fast without issue and it is easy to mount & dismount. I like that this includes two keys :::Setup::: I was able to assemble some of the bike without help but ultimately decided to go to YouTube. There you will find an official video on how to assemble the Z4 Pro. I found that to be much more helpful than the included guide. I felt that the guide lacked sufficient detail for me to follow. You must attach the front mud guard, front tire, headlight, handle bars and bike seat. I had a bit of a hard time getting the right foot pedal on but I took it to a bike shop only to be shown that one is installed clockwise and the other counter clockwise. I did feel awfully stupid once I saw how simple it was to install the right foot pedal, I want to share that with you so that no one repeats my mistake I was a little frustrated by that.. Please DO NOT forget to add air to the tires like I did it was not filled enough for my first ride. The fat tires can hold 20PSI as per the sidewall on the tires themselves. After all this then all that is left to do is charge the bike itself. The manual states that it will take 5 & ½ hours to fully charge. That was not the case for me it took literally half of that, perhaps it was partially charged. :::General Thoughts::: This is a folding bike; some may find that to be appealing but to me I do not see the point of it. What I do wish to discuss is the quality of the bike. The seat has plenty of padding and I appreciated that so much. You will find that some bike seats do not offer enough cushion or are just so small that it ends up causing pain and discomfort. The mud guards cover a good amount of the tire so you cannot pull back the bike and walk it going down the stairs. You will have to find another way. The handle bars are comfortable and do not cause hand irritation, the gear switcher is very easy to use, there is an included bike bell and it is very small and does not take up a lot of space, the throttle is small too but responsive. It was a little surprising at first at just how the bike has so much acceleration. You do get used to it in time. The display is a good enough size, the text is large enough to read, it is backlit and can be powered on or off by pressing the top left button and holding it for a few seconds. This also powers on and off the headlight, I would have liked for the headlight to be slightly larger but it is plenty good I must say. The rear rack is very sturdy and can accommodate someone who is lightweight to ride with you but that would not be very comfortable. You can also attach saddle bags or other items; I will get other accessories in time like attachments for making food deliveries and possible attachments for water bottles and etc. I think this would be an ideal bike for making Uber, Doordash & GrubHub deliveries. For those who do not want that it is okay too I am having a great time riding around my area and even running small errands with it. Be sure to get a good bike lock for this you do not want someone walking off with it. The kickstand is very strong and it can support the weight of the bike. The bike pedals are adult sized and fit all shoe sizes I wear a size 12 and did not have any issues with my foot slipping. I like that the bike has pedal assist I was able to go up hills with ease and not having to stand or break a sweat. The power kicks in automatically and I found that to be awesome.This has disc brakes and I tested them many times going fast, and even down hill and it worked great every time. :::Pros & Cons::: Pros: - Easy to assemble - Sturdy - Fast - Easy to use - Looks good - Fast - Fun - Two keys included Cons: - Keyhole is on the bottom of the bike and is difficult to reach :::Closing thoughts::: I believe that I covered everything that I found to be relevant and that may help you decide if this is a good purchase for you. There is just so much value in this product it really is great I love it so much. I like not using my car nearly as much especially traveling locally gas is just annoying having to pay more just because someone says they want to charge on any given day. Although the battery on this bike is rated to have a 50-mile range I have not owned it long enough to test that. Overall, I like this way better than my Trek FX hybrid bike. It is just amazing and I think you will agree. :::TL;DR::: You want a form of transportation that you will not have to pay insurance, registration, or gas then this might be right up your alley. It will not be for long distances but locally this will get the job done. It is great for work or play so if you need an e-bike then this is “THE ONE” to get.

My first time getting a chance with one of these! Mine came nicely packed in a box that I had to cut down to get in the trash. Opening it up the bike was in its folded position with the front wheel loose. What I would like to mention is holy mother of zip ties! This thing no joke must have had 50 zip ties! Assembly was easy the bike is equipped with quick release levers for the seat and handle bars. You slide the disc brake in and tighten up the lug nuts. One thing no matter how I adjust the brakes I’m getting rubbing on the disc. It goes away while riding though and that’s really what it’s about. The seat isn’t very comfortable I wish they used memory foam or something softer. Anyways the bike was fun to ride. After I built it (came mostly assembled) I couldn’t stop going back and riding it. It’s really hot outside but I’d come home and chill and want to get right back on it. I took it through some rough area and it has front shocks but the beefy tires make it for a rough ride. The throttle is a push down lever and I often maxed out at 20mph. The miter kicks in depending when you peddle as well and overall I just love this thing. If you buy it you’ll have a blast riding it!
