Rock Machine Storm e90-29 TOUR Black/Olive VZOREK is an electric mountain bike designed for long rides and everyday off-road commuting. It’s built around the Sport Drive mid-drive motor and a dual-battery system for extended range. Its spec targets the mid-range category, where the balance of range, handling, and easy maintenance matters most.
The frame is made from an aluminum alloy and is designed to integrate both the mid-drive unit and the batteries into the structure. The mid-drive motor keeps the center of gravity low, which improves stability on slow climbs. The geometry is touring-oriented, focusing on control off-road and confidence on longer routes. The bike is available in size M for 160–185 cm and L for 175–195 cm.
Drivetrain: microSHIFT Acolyte shifting is set up as 1x8. The microSHIFT Acolyte CS-H083A cassette has a 12–42 tooth range, and the chain is a KMC e8S.
Brakes: Alhonga HJ-OD07 hydraulic disc brakes use Alhonga HJDXR 1606 rotors. Rotor diameter is 160 mm front and 160 mm rear.
Wheels and tires: The bike is built around 29" wheels and uses Rubena Cheetah 29x2,1" tires. The Solon hubs feature a quick-release front hub with Centerlock mounting, and a rear hub with sealed bearings.
Cockpit: One1 Alloy MTB AL-325BT handlebars are 720 mm wide with a 25 mm rise. A One1 TDS-C342 Alloy stem is paired with a One1 Alloy 30,9 mm suspension seatpost and HERRMANS CLIK DD37 grips.
The combination of 29" wheels and 2,1" tires boosts stability and tracking on gravel and in lighter off-road terrain. The RST Blaze coil fork with 100 mm travel filters out typical bumps and reduces hand fatigue on longer routes. The Sport Drive MD250S mid-drive motor with 90 Nm of torque helps you maintain cadence on steeper climbs. Hydraulic disc brakes with 160 mm rotors provide predictable modulation on wet surfaces and on longer descents.
Rock Machine Storm e90-29 TOUR is designed for riders who prioritize range, simple operation, and off-road stability. It’s well suited to all-day trips, forest roads, gravel, and mixed routes with frequent climbs. Compared to more sport-oriented e-bikes with longer travel, it focuses on efficiency and touring ergonomics.
