Shengmilo M90 — 29" Big-Wheel Electric Mountain Bike

Roll over obstacles with supreme momentum and smooth riding confidence. The Shengmilo M90 is powered by an EU-compliant brushless rear hub motor offering a 250W rated continuous output and a 500W peak power surge (56 N·m torque), paired with a large-capacity 48V 17Ah (816Wh) removable lithium battery that provides up to 60–80 km (37–50 mi) of pedal-assist range. In strict compliance with European road safety standards (EN 15194 / EPAC), the top speed is factory-limited to 25 km/h (15.5 mph) in pedal-assist mode with the twist throttle disabled.
