I have used two Electric Bromptons, both have made a signicant differance to ease of peddling, the benefit is most noticable on the hills.Just ordered a Woosh Frog kit for brompton ro ease my ancient legs. Looking dforward to seeing what difference it makes to hills and headwinsds.
I realise that, or there would be a choice. Just planting a seed of an idea, maybe ask your supplier? It would be useful on the front of a Brompton.I don't have it, sorry.
