I am 62 years old and live in a hilly town, and have decided to invest in an e-bike. I have travelled to several different bike shops to try out different models (Trek, Pedago, Townie, Faraday and now Kalkhoff). For my body shape and fit, the Kalkhoff fAgattu Impulse (2016 model) feels like a better bike, but the "lightness" and portability of the Faraday Courtland S made me feel more in control. My average commute to work on the bike will only be 3 miles each way, but I am worried about the range on the Courtland. Any users out there who have ridden these two models have any suggestions? THANKS!
