I love the ability to get a little E-assistance on my own bike rather than purchasing a very heavy dedicated E-bike. With the Swytch kit installed (actually not too difficult for a 66 yo woman) and good customer service throughout the process, I have enjoyed riding my bike again with a belief that I can conquer the hills. However, I have an occasional problem with getting the throttle (optional equipment) to engage when I need it on those hills. It seems to work best with little torque on the pedals, but that is counter to my needs. Also, wish it were easier to use the controls to change the Pedal Assist level while riding, but I find it difficult to do without multiple taps on the buttons as it is not particularly responsive. But that PA, even on L1, is powerful. I never use it on L5, afraid to try!
