A:AnswerYes, although I don't think you will ever need to use this option on a single ride. Battery life is 3.25 to 3.5 hrs but you can add an external power pack and extend the range to 7 - 12 - 18 or even 24 hrs of recording time. I currently use a 32gb card good for about 6.5 hrs of recording but could go up to 120gb. If you want to see results from bike rides look me up on Youtube and use my comment section if you have any other questions about this product.
