Rock Machine eSTORM 70 TOUR mountain bike GLOSS BLACK is an e-bike on an MTB platform with a focus on everyday commuting and weekend rides. It combines a Sport Drive mid-drive motor with a full touring equipment package for practical day-to-day use. In terms of performance, it sits in the mid-range, prioritizing stability, range, and ease of use.
The foundation is a frame made from heat-treated 6061-T6 aluminum alloy, designed for a comfortable riding position and predictable handling. The geometry aims for confidence at lower speeds and easy maneuvering in traffic. Front suspension is handled by an RST Blaze fork with 100 mm of travel for rough asphalt and gravel. The FSA ZS44/ZS56 headset supports a solid front end under braking and when holding a line.
Drivetrain: microSHIFT ACOLYTE shifting comes in a 1×8 setup with a 12–42-tooth cassette range. Shifting is handled by a microSHIFT Acolyte RD-M5185M rear derailleur and a KMC e8S chain.
Brakes: Alhonga HJ-OD07 hydraulic brakes use Alhonga HJDXR 1606 rotors with a diameter of 160 mm. Braking performance remains consistent under load and in wet conditions.
Wheels and tires: The built wheels are based on Stars J30 rims and Solon hubs, with a front quick-release and Centerlock mounting. Rubena Cheetah tires in 29×2,1" support stability and smooth out small bumps.
Cockpit: One1 Alloy handlebars are 720 mm wide with a 25 mm rise for greater control. A suspended One1 Alloy seatpost with a 30,9 mm diameter is complemented by a Selle Royal Vivo saddle and HERRMANS CLIK DD37 grips.
The Sport Drive MD250S mid-drive motor with torque up to 90 Nm transfers power through the cranks, so the bike feels natural when cadence changes. The combination of 29" wheels and 2,1" tires holds its line on gravel and adds composure on descents. The 100 mm-travel fork reduces impacts to the hands and helps traction on broken surfaces. The comfort-focused geometry and suspension seatpost reduce fatigue on longer rides.
eSTORM 70 TOUR is aimed at riders who commute, mix bike paths with farm roads, and want a fully equipped setup without additional modifications. It’s well suited to intermediate riders who prefer a simple 1×8 drivetrain and stable handling. Compared to more sport-oriented e-MTBs with a wider gear range, it prioritizes practicality and a touring-oriented setup.
