So how does the Speed Work ? I see on Trek Site it appears to be 20 and 28 : Obviously you still have to pedal : Does it mean on a flat surface if you are limited to 20mph assist : Were you to get going that fast it would stop assisting you past 20 mPH? I don't quite understand How these work : I've ridden pure Roadies and went faster the 20 MPH . But on a Verve No matter how fast I get going I've never gotten to 20MPH on a flat surface. Of course My riding Surface is Graveled Not smooth Black Top : So if I had a Verve E Bike that was capable of 28 MPH assist : Could I get going that fast ? Or are E bikes just for making it easier ?
