Specifications
Frameset
| Frame | The frame of the Rockrider E-ST 520 electric MTB is made of 6061 aluminium with hydroformed tubes. Why? The battery sits snugly on the frame to improve the robustness of this electric mountain bike.The forged aluminium parts make it compatible with the new 27.5"+ tyre format (wider than the 27.5") in the rear, while remaining easy to manoeuvre. We've kept a frame geometry with short bases for easier steering. |
|---|---|
| Suspensions | Ride over obstacles (roots, pebbles, stones, etc.) easily thanks to the Rockshox 30 SILVER fork with 120 mm of travel.This fork has:- A coil spring for maximum sensitivity and reliability - a lockout and rebound adjustment for better control, depending on the terrain |
Wheels
| Wheels | So you feel safe on any terrain, and for traction suited to your motor, the E-ST520 electric MTB is equipped with Hutchinson Cougar 27.5" tyres with a 2.4" cross-section. Our test riders particularly liked these tyres for their good grip. Mounted on wide rims, these tyres ensure grip, traction and comfort on any terrain. |
