I bought an EbikeBC 350 watt front motor kit and had it installed on a new bike in June 2016, I have now ridden over 5000 km and it is still working great. Very enjoyable ride. My daily commute is 22 km (downtown to UBC and back). Great for the hills. Except for the hills I almost never have to go above level 1 assist. It has shortened my commute time by 25% even at this low level. Excellent investment. The only problem that I have had is some issues with getting the break cut out switches to stick in the right location. The 3M sticky tape tends to come lose after some time. I can see that there is an epoxy job in the future. Still a wonderful product and so worthwhile.
