The Rock Machine Blizz e40-29 is a hardtail e-bike designed for maximum control and fun on the trail and during day trips. Featuring innovative Trail Ultimate geometry, it provides stability and comfort over a variety of terrain. This model is the ideal choice for riders looking for a reliable and powerful e-bike for demanding trails and leisurely rides.
At the heart of this machine is the Shimano STePS EP6 motor, which boasts 85Nm of torque - that means great power on hills and instant response to your every move. Whether you're taking on a steep trail or a long tour, the 504 Wh Darfon battery will keep you in the saddle for hours, while the sleek Shimano SC-EM800 display gives you all the key riding data in a clear and modern design.
To make every descent smooth and every obstacle manageable, the bike is fitted with an RST Vibe air fork with 140mm of travel. This perfectly filters out bumps and gives a feeling of confidence even on the most challenging terrain. MicroSHIFT 1×8 gears with a range of 12-46 teeth ensure smooth and precise shifting, giving you the freedom to choose your ideal cadence without unnecessary complexity.
Speed doesn't matter if you don't have enough stopping power - Clarks Clout+ hydraulic disc brakes take care of that, giving you absolute control on even the steepest descents. And because a good ride requires stability, the bike sits on 29-inch wheels shod in WTB Ranger Comp 29×2.3s, which provide great grip and cornering confidence.
Every ride must not only be fast and stable, but also comfortable! The WTB Volt Sport saddle guarantees comfort even during long hours on the terrain, while the One1 Alloy telescopic seatpost allows you to adjust the saddle height in a flash for maximum control on technical passages.
