I left my Woosh gale folder on its stand at a camp site. When I got back, a woman was explaining to her daughter that it was a folding bike. They stood there looking at for a few minutes and as I reached them, the woman asked me about it. She was amazed when I told her that it was an electric bike and asked where the battery was. I pointed out the prominent aluminium battery behind the down tube.
Her reply was to the effect that had thought that it was just some sort container like a pannier.
The Woosh has a hub motor, unlike my Tonaro which is obviously motored because as one Belgian remarked to his wife when passing it parked at the Menin Gate, 'It's like a Motobecane'.
Ease of replacement is paramount, trying to pretend that you don't have a motor is ridiculous.
