Uhmm .... uhmmmm .... e-bike is not a magic bullet .... sadly not.
Weak knees - YES, an e-bike helps.
But you are still cycling, you are still using the same group of muscles .. same group(s) that compensate ....
HOW you use the e-bike becomes the decider ..... ride in zone 2 and zone 3 for a few hours, and it is just a lighter version of what ou normally did, and the same muscle groups are going to speaking to you. Short rides, using maximum boost, sitting in zone 1 .... now your muscles are having less of a workout.
The nice part of an ebike .... on good days you can turn down the assist and get a decent workout. On the not so good days, use more assist and keep the mobility going.
