Rock Machine eSTORM 70 TOUR Gloss Silver/Black/Grey is a trekking-oriented mountain e-bike for commuting and leisure. It is built around the Sport Drive mid-drive motor and a full set of equipment for everyday use. In terms of performance, it targets the mid-range segment, where balanced function, range, and ease of service are key.
The frame is made from heat-treated 6061-T6 aluminum alloy. The geometry is comfort-focused, with an emphasis on a stable riding position and confidence on rough surfaces. The Sport Drive battery is integrated into the frame, giving the bike a compact look. An RST Blaze suspension fork with 100 mm of travel complements the bike’s character for light off-road riding and urban bumps.
Drivetrain: microSHIFT ACOLYTE shifting runs in a 1×8 setup. The microSHIFT Acolyte rear derailleur is paired with a 12–42 cassette and a KMC e8S chain.
Brakes: Alhonga HJ-OD07 hydraulic brakes use ø 160 mm rotors front and rear. Control is handled by matching Alhonga hydraulic levers.
Wheels and tires: The wheels feature Stars J30 rims and Solon hubs, with a front quick-release and Centerlock mounting. Rubena Cheetah tires in 29×2,1" focus on low rolling resistance and stability.
Cockpit: One1 Alloy handlebars are 720 mm wide with a 31,8 mm clamp diameter. A One1 TDS-C342 Alloy stem is complemented by a One1 suspension seatpost and a Selle Royal Vivo saddle.
The combination of 29" wheels and 2,1" tires holds its line on gravel and calms the handling at higher speeds. The Sport Drive MD250S mid-drive motor delivers power through the chain, improving traction on steeper climbs. The 12–42 gear range helps maintain cadence on climbs even with cargo on the rear rack. The 100 mm fork and suspension seatpost absorb vibrations on cobblestones and dirt roads.
This model is intended for experienced riders who want a mountain e-bike for mixed routes and everyday commuting. It’s suitable for asphalt, cycle paths, and light terrain where stability and equipment matter. Compared to sport-focused e-bikes, it prioritizes practicality, lighting equipment, and load capacity provided by the rear rack.
