Battery life is good

Motor is impressively quiet and the assist is smooth. A touch heavy to carry upstairs, but fine on the road.

Does what's needed

Tyres grip well in the wet — felt planted in drizzle. Needed a quick tyre top‑up out of the box.

Ben C.
Good value

Comfortable to ride, even on longer weekend trips. Saddle was a bit firm at first, swapped to a gel one.
