Shengmilo S800 Key Features

The Shengmilo S900 is a high-performance electric mountain hybrid bike built for riders craving serious power, long range, and rugged capability. Its robust 1500 W motor and large Samsung battery deliver thrilling acceleration, strong hill-climbing ability, and long-distance rides across varied terrain.

Power & Performance
At the heart of the S900 is a potent 1500 W brushless motor producing strong torque and performance. Riders can reach speeds of up to 40 mph — especially in unlocked or private-land modes — with ample grunt for steep climbs and fast-paced riding.

Long-Range Battery System
The large 60 V 30 Ah Samsung battery provides real range flexibility. Lean on pure electric throttle and you can expect around 60–70 km, while combining pedal-assist pushes the effective range north of 90 km in mixed conditions.

Comfort & Control
A full suspension system with a dual-crown front fork and quality rear shock soaks up rough trails and uneven roads, while the wide 20″ × 4.0″ fat tyres offer excellent grip in mud, gravel, sand, and loose surfaces.

Happy with it

Arrived quickly and was packed properly. Shifting and controls have been easy to get used to. The display is simple and easy to read. Plenty of zip when you need it, but still comfortable for cruising. No complaints from us.

Thanks for your review — glad you’re enjoying it!

Smooth assist

Arrived quickly and was packed properly. The display is simple and easy to read. Battery has been consistent for my usual routes. Plenty of zip when you need it, but still comfortable for cruising. Would recommend it.

Comfortable ride

After a few weeks using it, I’m really happy with it. Assist comes in smoothly and makes hills much easier. Feels stable at speed and comfortable on longer rides. Plenty of zip when you need it, but still comfortable for cruising. No complaints from us.
