My first ebike was a low end Chinese model. The build quality wasn't great but it had controls that I really liked. Instead of the normal Pedal Assist with various levels it had a thumb lever (like a throttle) for pedal assist. It also had a hand grip throttle. This lever meant that I could make small adjustments when I wanted, for example, to keep an even distance when I was following my husband. It also meant that I could, without paying any attention, move the lever right down, instantly turning off pedal assist, or slide it right up with my thumb to give me full power or just move my thumb up or down just a little. I didn't need to know what level of pedal assist I was in and how many taps it would take to go back to zero or to full power. It actually worked much better than my more expensive bike that has the standard preset levels of pedal assist. Does anyone know of a brand of ebike that has the lever type of pedal assist? You can't search for it, because as soon as you do you get information on the throttle and not a pedal assist lever. If anyone has seen this type of control on a bike please let me know. When I first got it I was concerned that it wasn't the norm, now I don't know why it isn't having had both types of pedal assist controls.
