About Me


I am 69 and an avid mountain biker. I can go where I use to go at 40 but now I can GET BACK. Love this bike. You must take a test ride. If you have ridden other e-bikes for less money, you must try this one out. Awesome bike. Shifts great, great brakes, on the fly seat adjust and great battery life.

    This bike is the next step. Ride longer, faster isn't just a sales gimmick. Owning this bike just gets me wanting to ride and never stop. I'll ride with friends and hit another trail on the way home. The Trek frame and Bosch motor are tough enough to handle the endless fun. I'll even turn assist off when riding with the kids as their learning. I know, you'll say you aren't going to want an electric bike - you're wrong. This thing on singletracks is mind-blowing. I've tried other assist bikes, this is the one. This is winning.
