Electric / Carbon E-MTB / Full Suspension

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.
