I, too, am trying to find a trainer (not rollers) that can be used with an ebike. We have some seniors that have or want ebikes, but are in terrible shape physically, have fears of falling, haven't ridden much, are concerned about "all those functions". For them a trainer is perfect using a step through ebike. They can get some indoor exercise where the bike is stable, they can get used to getting on and off a bike, they learn how to control the functions, etc. Problem is, we can't connect our current trainer to the ebikes because the electronic wires run through the middle of the hub nuts!!! No way to connect with pinching/cutting/breaking the connection. Can't attach to frame instead of hub (should be a way to do that). Very frustrating. Rollers are too unstable for the seniors....front fork support/roller set up?....not with an ebike....again because of how they are configured. Surely with the new explosion of sales in bikes some 'trainer' company has or can come up with a solution!! Very frustrating.
