My husband just converted my trail / commuter bike that has been sitting idle because I find the hills in Vancouver too challenging. No longer! What a marvelous e-bike system, the quality is really good. Now I will never fear to go out for a ride, whatever the hills I may find. The bonus: with the lower demand aerobically and on my back/leg muscles, I can concentrate more on my form, as spinal stenosis can mean a very sore back if you don’t get the posture right while you ride. Bliss.
