Rock Machine Torrent e50-29B Easy Entry mountain e-bike Gloss White/Black is a hardtail for commuting, leisure riding, and lighter terrain. It’s built around a Bosch mid-drive motor and 29" wheels, so it’s aimed at riders looking for confident traction and easy step-through mounting. The component spec matches the more affordable mid-range of everyday e-bikes.
The frame is made from Al-6061 T6 aluminum alloy with custom-shaped tubes and Smooth Welding finished welds. The Easy Entry concept lowers the standover height and makes handling easier both in city traffic and on trails. Fun Ride Geometry focuses on stability and predictable steering on 29" wheels. The frame features internal cable routing and a dropout prepared for fenders and a kickstand.
Drivetrain: microSHIFT Acolyte shifting comes in a 1×8 setup with a 12–46-tooth cassette. A KMC e9S chain handles the drive, and the crankset uses a 38-tooth chainring.
Brakes: Shimano BL-M4100/BR-MT410 hydraulic disc brakes use Shimano SM-RT30 rotors with a 180 mm diameter. The same rotor size front and rear supports consistent modulation.
Wheels and tires: The wheels are built on WTB SX19 rims with 32 holes and Shimano TX505 hubs with quick releases. WTB Ranger Comp tires in 29×2,25" are aimed at versatile use on gravel and forest roads.
Cockpit: One1 Alloy handlebars are 720 mm wide with a 25 mm rise. Comfort is handled by a WTB Comfort Wide saddle and a One1 Alloy 30,9 mm seatpost with Velo Ergo Lock-On grips.
The combination of 29" wheels and an RST Aerial air fork with 120 mm of travel helps hold a line on rough gravel and rooty sections. The Bosch Performance Line Cruise mid-drive motor with 65 Nm of torque delivers smooth power delivery when pulling away and on long climbs. The 12–46-tooth cassette range keeps cadence manageable on steeper grades without the need for a front derailleur. The frame-integrated battery lowers the center of gravity, which translates into calmer, more stable handling on faster descents.
This hardtail is for riders who want an e-bike for commuting, cycle paths, and light to moderately demanding off-road routes. The low step-over will also appeal to those who stop frequently, carry panniers, or prefer easier mounting. In this class, it makes sense for riders who prioritize the proven Bosch drive system and easy servicing over sporty racing ambitions.
