Dual disc brakes deliver responsive, dependable stopping power.

Great E-Bike for teens and young adults

So far the only negative part about this bike is that there is not instructions on what the program mint and functionality of the bike can do. Bike was a little hard to put together with just one person but so far it works great!! My boys and me put 9 miles in the bike today after getting it and only used 1/4 of the battery. I myself am about the weight of both my boys (13 %26 17). We got this bike because my son's friend down the street has one now for a week and it's performing great for him.
