S2 vs S1 vs SX: which low-step Kuma is right for you?

Choose the S2 for light, simple city riding at the best price, the S1 if your route has hills, and the SX if you want the strongest climbing and a belt drive with stepless gears. All three have an easy step-through frame, a 504Wh Samsung battery with up to 90km of range, racks, mudguards and lights, and qualify for the bike to work scheme.

Who each bike suits

  • S2: flatter commutes, errands and riders who want the lightest, best-value step-through.
  • S1: hillier routes where a hub motor would feel underpowered.
  • SX: the M1's drivetrain in a step-through frame, for the strongest climbing and the least maintenance.

Frequently asked questions

Is a low-step e-bike only for shorter riders?
No. Low-step frames are popular with anyone who wants to get on and off easily, including riders carrying a child seat, riding in a skirt or suit, or stopping often in traffic.

Which low-step Kuma is best for hills?
The SX (80Nm), then the S1 (65Nm). Both are mid-drives that climb through the gears.

Is there a low-step version of the M1?
Yes, the SX uses the same motor, belt and Enviolo hub.
