750 W peak power meets 64 km freedom – ride further, faster, every day.
The Racer electric mountain bike blends a lightweight
carbon-steel chassis with a peak 750 W brushless hub motor
and a 36 V 10.4 Ah UL-certified battery, giving you up to
22 mph (35 km/h) top speed and 40 mi (64 km)
range in pedal-assist mode.* A coil-spring front fork,
21-speed Shimano-compatible drivetrain and versatile
26 × 2.1 in (54-559 mm) tyres deliver all-surface confidence
from weekday commutes to weekend trail runs.
The back-lit LCD shows speed, distance, assist level & battery bar, while
mechanical disc brakes, an integrated LED head-light and a
350 lb / 159 kg payload rating keep you safe and ready for
cargo runs. Ships 90 % pre-assembled with tools, charger
and keyed battery lock for quick, no-stress setup.
- 4 ride modes: throttle, 5-level PAS, manual & walk-assist.
- Quick-swap battery – full charge ≈ 4 h, locks in place for security.
- Shimano 21-speed trigger shifting – crisp, chain-safe gear changes.
- Mechanical disc brakes – consistent stopping in wet or dry conditions.
- Universal fit – ideal for riders 5′ 3″–6′ 4″ (160–193 cm).
