Shengmilo S900 PRO – 3000W Off-Road Electric Dirt Bike
The Shengmilo S900 PRO is the one you buy when “enough” isn’t enough. A 3000W rear motor with 150 Nm of torque fires you out of corners and up gradients of up to 45°, and a huge 2,100 Wh battery means you run out of daylight long before you run out of charge – up to 50 miles on the throttle alone. Unlocked, it reaches 40 mph.
It’s built like a motorbike, not a bicycle: a dual-crown front fork, full rear suspension, 19-inch rims and chunky all-terrain tyres. Made for private tracks, fields, woodland and anyone who wants proper off-road fun without the noise, fuel or fuss of a petrol bike.

The Shengmilo S900 PRO, Part by Part
3000W of Instant Pull
Twist the throttle and the 3000W rear hub motor delivers 150 Nm of torque straight away – no gears to find, no clutch, no engine to warm up. It drags you up slopes of up to 45°, powers out of muddy ruts and keeps pulling with a rider and kit on board. Choose the 15.5 mph setting while you learn the bike, then unlock the full 40 mph when you’re ready.
2,100 Wh Battery: The Biggest in the Range
The removable 60V 35Ah battery holds 2,100 Wh – more than any other Shengmilo. That’s 37–50 miles on the throttle alone, and over 50 miles if you pedal along. Slide it out and charge it indoors at a normal plug socket overnight. As with any e-bike, you’ll see less range in the cold, at full speed or on steep climbs.
Motorbike-Style Suspension
Up front, a dual-crown fork – the type you see on off-road motorbikes – keeps the steering precise when you land a jump or hit a rut at speed. At the back, a rear shock keeps the tyre on the ground for grip and control. The result: you can ride harder, for longer, without getting shaken to bits.
19″ Wheels with Real Off-Road Tyres
Instead of bicycle fat tyres, the S900 PRO uses 19-inch rims with 70 mm all-terrain tyres, much like a small dirt bike. The deep tread bites into mud, sand, gravel and loose stones, and the smaller, stronger wheels handle hard landings better.
Brakes Built for 40 mph
Hydraulic disc brakes front and rear give powerful, controllable stopping with a light pull of the lever. Touch the brakes and the motor cuts out instantly, so you’re never fighting the power to slow down.
Pedal When You Want To
Ride on throttle only, use pedal assist, or pedal on your own. The Shimano 7-speed gears let you add your own effort on long days out to squeeze even more miles from every charge.
Shengmilo S900 vs S900 PRO: What’s New
The S900 was already our most powerful bike. The PRO doubles the motor power, adds a bigger battery and swaps the fat tyres for proper off-road wheels.
| Feature | Shengmilo S900 | Shengmilo S900 PRO |
|---|---|---|
| Motor | 1500W rear hub | 3000W rear hub |
| Battery | 60V 30Ah (1,800 Wh) | 60V 35Ah (2,100 Wh) |
| Range on throttle only | 37–43 miles | 37–50 miles |
| Wheels and tyres | 20 × 4.0″ fat tyres | 19″ rims, 70 mm all-terrain tyres |
| Top speed (unlocked) | 40 mph | 40 mph – same |
| Front fork | Dual-crown | Dual-crown – same |
| Brakes | Hydraulic disc | Hydraulic disc – same |
Double the Motor Power
3000W instead of 1500W. More punch from a standstill, more pull on climbs and more in reserve with a heavier rider.
A Bigger 2,100 Wh Battery
300 Wh more than the original S900, so the extra power doesn’t cost you range – up to 50 miles on the throttle.
Dirt-Bike Wheels
19-inch rims with 70 mm all-terrain tyres replace the 20 × 4″ fat tyres, for sharper handling and better grip in loose ground.
Same Tough Chassis
The dual-crown fork, rear suspension and hydraulic brakes riders loved on the S900 all stay.
S900 PRO or S600 PRO?
The S900 PRO is for off-road fun and speed: the biggest battery, the most climbing power and motorbike-style suspension. The S600 PRO is the all-rounder: two-wheel drive, wide fat tyres and a higher load rating. See the full S600 PRO vs S900 PRO comparison.
Where Can I Ride the Shengmilo S900 PRO?
In Great Britain, a bike only counts as a normal electric bike if its motor is 250W or less and stops helping at 15.5 mph. With 3000W and a 40 mph top speed, the S900 PRO is in a different league, so it’s made for private land – your own land, or land where you have the owner’s permission. It isn’t for public roads, cycle paths or bridleways. Always wear a helmet and protective kit. The official GOV.UK electric bike rules explain the details.
