Shengmilo S900 - 1500 W High Performance Electric Fatbike

The Shengmilo S900 is an exceptional electric bike designed for riders who demand raw power and rock-solid stability. Fitted with a 60 V motor/battery system, it offers torque and acceleration far exceeding market standards. Its reinforced 6061 aluminium frame, combined with full suspension and 4-inch wide tyres, allows you to tackle the toughest terrain, such as sand, snow or mountain trails.

Who is this bike for?

This model is particularly suited to:

• Thrill-seekers looking for high top speeds (up to 65 km/h).

• Riders in mountainous areas with steep gradients (up to 45°).

• Cyclists seeking massive range for long expeditions.

• Heavier riders requiring a frame and motor capable of supporting a heavy load.

Performance and range

The S900 stands out thanks to its 60 V architecture, rare on the market, which powers a 1500 W rear motor delivering a colossal torque of 150 Nm.

• Claimed range: Up to 100 km in pedal-assist mode (PAS) and 60–70 km in pure electric mode thanks to its 30 Ah (1800 Wh) battery.

• Top speed: Up to 65 km/h (unrestricted).

In real-world conditions, range depends on:

• Intensive use of the throttle.

• The total weight of the load (up to 150 kg).

• The gradient (capable of climbing 45° slopes).

• Fatbike tyre pressure.

Key strengths

✔ Exceptional motor power (1500 W / 150 Nm)

✔ Samsung 60 V 30 Ah battery (massive capacity of 1800 Wh)

✔ Superior comfort with dual suspension (double-crown fork)

✔ High-safety hydraulic braking with motor cut-off

✔ Outstanding climbing ability (45°)

Weaknesses

❌ Very heavy (48 kg), difficult to handle without the motor

❌ Not approved for public cycle paths (category L1e-b)

❌ Takes up a lot of storage space

❌ Long charging time (8 to 10 hours) due to the battery size

Comparison and positioning

The Shengmilo S900 is positioned as a super-performance electric fatbike. It far outperforms standard 250 W or 500 W models in terms of torque and speed. It is the ideal choice for off-road riding and private terrain where power takes priority over lightness.

This bike is for you if:

✔ You're looking for the strongest acceleration on the market.

✔ You need to tackle extremely steep hills.

✔ You want a significant real-world range in electric mode.

✔ You ride on loose surfaces (sand, snow, mud).

This bike is NOT for you if:

❌ You're looking for a lightweight city bike.

❌ You want to ride legally on cycle paths without registration.

❌ You regularly need to carry your bike at arm's length.
