One of the big issues with e-bikes - be they electrically assisted bikes or full on electric motorcycles - is recharging. This is a particular problem for those of us who don't live on the ground floor. Carting a bike up stairs to your flat can be no joke for a smaller, weaker person. So are there e-bikes with drive modes that help with this? I'm thinking of something like resting the back wheel on the floor and the motor assisting with the stairs.
