|---|---|---|---|
| Who it suits | |||
| Best suited to | Off-road or private property only as sold. Riders on private property who want a folding bike with a big battery and a throttle. | The train and lift commuter who wants a folder with no chain and no gears to think about. | |
| Main trade-off | It is not road legal as sold, and at 28.5kg it is heavy for something you are meant to carry. | A 346Wh battery is small, so the 100km range claim is a best case rather than a commute you can count on. | |
