Mixed results with the Summit kit. I bought the Hilltopper Summit kit. The documention was not accurate and incomplete. The kit met my needs but not my expectations. The way to reset the trip counter is not obvious and their tech did not know the proper way to do it. There are several features that the display is capable of but not implemented. I expected more of their top of the line kit. The display was initially defective but their tech was good about sending another one. The throttle has a dead zone and it is difficult to control the power.

EV conversion kit is working fine on my mountain bike I have been using my EV converted mountain bike at least 3 or 4 times a week for pleasure and workout. I'm relying on the EV parts as I am out of energy going uphill in Boulder Colorado. I am happy with the Hilltopper conversion kit on my mountain bike and it is working as I expected. By the way, it was easy to replace the flat tire in front of my mountain bike with the motor in front. I'm planning to convert my other bike to EV conversion too in a few months. Great job guys
