Twitter EM5 2RD
Engineered to flatten climbs and extend every ride, the Twitter EM5 2RD pairs a Bafang mid-drive motor with a high-capacity 720Wh Samsung 21700 battery for up to 150 km of pedal-assisted range. Its lightweight AL7005 alloy frame, air-sprung remote-lockout fork, and 12-speed wide-range drivetrain are built to charge technical singletrack and rolling trails alike. A top-tube integrated Bafang LCD display, torque-plus-cadence sensing, and SHIMANO 180mm hydraulic discs keep power delivery natural and control instant — from the first climb to the last descent.
Key Features
- ▪ Bafang Mid-Drive Motor — M510 (36V/250W, 95 N.m) or M560 (48V/500W, 130 N.m) for class-leading torque on steep trails.
- ▪ 720Wh Samsung 21700 Li-ion Battery delivering 120–150 km of pedal-assist range, fully charged in 6–7 hours.
- ▪ AL7005 Alloy Boost Frame with flat-weld smooth tubing, internal routing, Thru-axle 12×148 Boost and UDH hanger.
- ▪ Air-Sprung Remote-Lockout Fork (RS MgAl, 15×110) — ROCKSHOX JUDY on the top variant — for plush, tunable travel.
- ▪ 12-Speed Wide-Range Drivetrain — SHIMANO DEORE M6100 or Wheeltop EDS OX wireless with 11–50T cassette.
- ▪ SHIMANO MT200 Hydraulic Disc Brakes (180/180mm) with 29/27.5×2.25" trail tires on double-wall alloy rims.
