A:AnswerPart of riding any bike is balance. You must be able to stay up on 2 wheels without falling down. If you could never ride a regular bicycle without falling down, this bike is not for you.
A:AnswerYes - the seat height is easily adjustable. I'd like to adjust the handlebar height but haven't fund directions for that yet; still don't know if it's possible.
A:AnswerLike any electrical device, you don't ever want to submerge a battery or any other component of the electrical system. Or even get them overy wet
Of course the big question here is " who would want to be out in the rain anyway on a bike?
Or who would want to ride through water deep enough to submerge the motor/hub/battery??
Final comment: this bike is not for anyone short on common sense
