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.
Engineering & Design Highlights
Mid-Drive Motor
A centrally mounted Bafang mid-drive unit places mass low and central for balanced, natural handling. Choose the M510 (36V/250W, 95 N.m) for efficient trail riding or the M560 (48V/500W, 130 N.m) for maximum climbing torque — both with torque-plus-cadence sensing for instant, intuitive assist.
Integrated Down-Tube Battery
A 720Wh Samsung 21700 Li-ion pack seats cleanly into the down tube for a low centre of gravity and a stealth profile. It powers 120–150 km of pedal assist on a single charge and recharges fully in 6–7 hours, ready for back-to-back trail days.
Trail Wheelset & Brakes
Double-wall alloy rims (W25×H21mm) on 4-sealed-bearing Boost hubs, wrapped in grippy 29/27.5×2.25" trail tires. SHIMANO MT200 hydraulic disc brakes with 180/180mm rotors deliver consistent, powerful, all-weather stopping.
Drivetrain Configurations
SHIMANO DEORE M6100 — 12-Speed
Bafang M510 mid-motor (36V/250W, 95 N.m peak 130 N.m) paired with a SHIMANO DEORE M6100 12-speed shifter and rear derailleur, 38T crank and 11–50T cassette. RS air remote-lockout fork for efficient, all-day trail riding.
SHIMANO DEORE M6100 — 12-Speed
Stepped up to the Bafang M560 mid-motor (48V/500W, 130 N.m peak 150 N.m) with the same SHIMANO DEORE M6100 12-speed drivetrain, 38T crank and 11–50T cassette — more power and torque for steep, technical climbs.
Wheeltop EDS OX — 12-Speed Wireless
Bafang M560 mid-motor (48V/500W) matched to a Wheeltop EDS OX 12-speed wireless shifter and rear derailleur for clean, cable-free, app-tunable shifts. ROCKSHOX JUDY air fork, 38T crank and 11–50T cassette top the range.
