The installation was smooth other than some difficulty with the fork fit. The motor assist engages in a predictable way that is easy to get used to when riding. The basic display is not easy to use when changing settings, requiring the manual to figure out. This is mostly ok except for it would be nice to have an easy to change power assist percentage on the fly. The stated battery range should also provide some adjustments for temperature and hills because I was getting about 40% less than stated on a hilly ride. Finally, the controller could use some improved voltage management on the battery because I would drop from 3 bars to cutting off completely when I rode up hills.
