Rock Machine VYÖRY e50 S fatbike e-bike Gloss White/Black SAMPLE is an off-road e-bike in the fatbike category designed for riding on snow, sand, and rough terrain. It uses a Shimano EP8 mid-drive motor and a rigid fatbike fork, focusing on functional equipment for year-round use. In terms of performance, it sits in the mid-range with an emphasis on traction and range.
The foundation is a frame made from heat-treated 6061-T6 aluminum alloy, designed for high loads and for mounting a rack and fenders. The Fat Fun geometry combines stability in loose terrain with confidence at low speeds under load. The bike is produced in sizes S, M, and L, with reach of 423/439/461 mm and stack of 566/579/588 mm. Chainstay length is 458 mm and the head angle is 68°.
Drivetrain: Shimano Cues SL-U4010 RapidFire Plus shifting runs in a 1×9 setup. A Shimano Cues RD-U4000 GS rear derailleur is paired with an 11–46 cassette and One1 cranks with a 34-tooth chainring.
Brakes: Shimano MT200 hydraulic disc brakes use Clarks Stainless 180 mm rotors front and rear. The lever feel is tuned for predictable engagement off-road.
Wheels and tires: WTB Custom Build Fatbike TCS Wheelset wheels come in 26". Maxxis Minion FBF and FBR tires in 4.8" width increase the contact patch and hold a line in soft terrain.
Cockpit: One1 Alloy handlebars are 720 mm wide with 25 mm rise, paired with a One1 MAS-D61808 31.8 mm stem with a ±15° angle. The WTB Koda Sport saddle and One1 30.9 mm seatpost are aimed at durability for off-road riding.
The fatbike concept with 26×4.8" tires increases mechanical grip and smooths out small bumps without suspension. The Shimano STePS DU-EP600 mid-drive motor with 85 Nm helps maintain speed in deep surfaces and when starting uphill. Geometry with a 68° head angle and a longer wheelbase promotes stability on snow and in mud. The rigid fork sharpens steering precision but requires managing tire pressure.
This fatbike e-bike is intended for experienced riders who need traction in winter, on sand, or on rough forest roads. With a 150 kg load capacity, it’s also suitable for riding with gear and for heavier riders. Compared to a standard trekking e-bike, it offers significantly higher capability in challenging terrain, but slower riding on smooth asphalt.
