The hub motor is excellent. It gives you all-wheel drive which is a bit odd in a bicycle and can catch you out in very slippery conditions (mud on paved towpath by side of river, this is slippery for every bike and every foot, but the front-wheel drive can cause an extra slide).
The battery lasts well. I don’t always need it hiked to full power (setting 4) and am happy to ride it at anything from 1-3. There is a boost button that provides extra oomph for climbing hills or getting away quickly.
It’s not crazy heavy.
It’s a properly vertically-integrated e-bike where everything is designed together and works together. If you want a bicycle with a motor and battery bolted-on, there’s plenty of alternatives. The service has been excellent from VanMoof and the only flaw is that the rear mudguard somehow doesn’t work and my entire back is covered in mud on a wet ride.
I paid full-price and it is an outstanding bicycle. I imagine the S3/X3 will be even better. I resisted the chance to buy one of those early.
