EM19 - Cyctrac Electric Mountain Bikes
Twitter EM19 Cyctrac
Built to climb harder and ride farther, the Twitter EM19 Cyctrac is a full-suspension carbon e-MTB driven by a Bafang M820 mid-drive motor with 85 Nm of torque and a fully integrated 720Wh Samsung battery for up to 130–150 km of pedal-assist range. Its high-modulus carbon AM frame pairs 145mm of DNM air-shock rear travel with a 150–160mm air fork, while a 12-speed drivetrain, four-piston hydraulic disc brakes on 203mm rotors and 29/27.5 MAXXIS trail tires keep every descent fast and controlled.
Key Features
- ▪ Bafang M820 Mid-Drive Motor — 36V/250W (48V/250W) with 85 Nm torque, torque & cadence sensing and IP X6 weatherproofing.
- ▪ Integrated 720Wh Samsung 21700 Battery — removable down-tube pack delivering up to 130–150 km of pedal-assist range, 5–7h full charge.
- ▪ High-Modulus Carbon AM Frame (Thru-Axle 12×148 Boost, UDH) with 145mm rear travel and a DNM air shock (200×55).
- ▪ Air-Sprung Front Suspension — RS 150mm air fork (ROCKSHOX-35S 160mm upgrade available) and a remote dropper seatpost (100/125mm).
- ▪ 12-Speed Drivetrain — choose SHIMANO DEORE M6100 or WheelTop EDS OX wireless, on an 11–50T cassette for steep climbs.
- ▪ TEKTRO M535 Four-Piston Hydraulic Disc Brakes (203/203mm) with 29/27.5×2.4" MAXXIS trail tires and a top-tube LCD display.
