Twitter EC1 Cyctrac
Built to flatten climbs and stretch every ride, the Twitter EC1 Cyctrac is a mid-drive electric mountain bike powered by a Bafang M510 motor delivering 250W (Peak 790W) and 110 Nm of torque. A frame-integrated 720Wh Samsung 21700 battery feeds up to 130–150 km of pedal-assisted range, while torque-and-cadence sensing and a crisp Bafang-C080 LCD display keep the power smooth and intuitive. Backed by RS coil suspension, SHIMANO hydraulic disc brakes, and tough 27.5×2.4" tires, the EC1 turns trails, hills, and the daily commute into effortless ground to cover.

Engineering & Design Highlights
Mid-Drive Motor
A centrally mounted Bafang M510 mid-drive motor (48V 250W, Peak 790W) puts power where it counts — low and balanced between the cranks. With up to 110 Nm of torque and torque-plus-cadence sensing, assist arrives naturally with each pedal stroke for confident climbing and effortless trail riding.
Removable Battery
A 720Wh Samsung 21700 Li-ion battery (48V 15A) integrates cleanly into the down tube and locks securely with a key, so you can remove it to charge indoors or swap it on the go. Full charge takes just 5–6 hours for up to 130–150 km of pedal-assisted range.
Smart Display
The Bafang-C080 LCD digital display and bar-mounted controller give you clear, at-a-glance readouts of speed, assist level, and battery status. An integrated USB / Type-C port keeps your devices charged, and the speed setting steps from a 25 km/h default up to 45 km/h with the Remap option.
