Description
Torque is the only honesty a motor has. A board that claims 30 km/h and dies on the first rise is not a commuter, it is a toy. The Commuter Hub is the drive unit for builders who would rather feel the hill flatten under their feet than read a spec sheet about it.
The hub motor sits inside the wheel, which means no belts to tension, no pulleys to align, and no exposed drive train to collect gravel. Choose 70mm for a lighter, lower board or 90mm for clearance and grip at speed. Single drive keeps the build light and the wallet intact. Dual drive turns a longboard into something that pulls away from traffic without hesitation. The motor is sensorless, so it starts with a push and then reads rotor position from back-EMF, which removes the most fragile cable on the whole board.
Every unit is rated for 24 to 36 volts, spins at up to 2640 rpm no-load at a 110KV constant, and reaches roughly 85 percent efficiency under load. The PU sleeve is replaceable, which matters: the urethane wears out long before the copper does, and on most hub motors that single fact decides whether the board is a five-year project or a one-season experiment.
Hills do not get shorter. The motor just makes them irrelevant.
What the Build Gets
- Hub architecture the motor lives inside the wheel, so there is no belt, no pulley and no exposed drive train.
- Sensorless start push to start, then back-EMF reading takes over, removing the hall sensor cable entirely.
- 70mm or 90mm wheel a smaller wheel keeps the board light and low, a larger one adds clearance and grip.
- Single or dual drive one motor for economy and range, two for traction and acceleration.
- Replaceable PU sleeve the urethane is a consumable, so wear does not scrap the motor.
- Electronic braking brake force scales with speed, using the same windings that drive the wheel.
- 24V to 36V system support fits the voltage bands most DIY boards already run.
Numbers That Matter
- Top speed approximately 38 km/h in a properly matched build.
- Efficiency roughly 85 percent, which is the difference between a 20 km ride and a 12 km ride.
- Kv constant 110KV, giving 2640 rpm no-load at 24 volts.
- Maximum load rated to 100 kg of rider plus gear.

Where It Belongs
This is the drive unit for the person building a board instead of buying one, and for the workshop repairing boards other people built. Commuters use it to convert a retired longboard into a short-range commuter that charges under a desk. Campus riders pair dual 70mm motors with a modest battery for a board that folds into a car boot. Off-road builders step up to the 90mm wheel for clearance, then gear the battery for torque rather than top speed. Because the PU sleeve is replaceable and the electronics are sealed inside the hub, the same motor can survive several sets of urethane, which is the real measure of whether a drive unit was worth buying.
Frequently Asked Questions
Q: What ESC should I pair with it?
A: Any sensorless-compatible electronic speed controller rated for your pack voltage and current. Tell us your battery voltage and rider weight and we will point you at the right range.
Q: Single drive or dual drive?
A: Single drive for a light board, longer range and a lower budget. Dual drive if you want traction on gravel, harder acceleration and redundancy if one motor ever fails.
Q: 70mm or 90mm?
A: 70mm keeps the board low, light and quick to accelerate. 90mm adds clearance over curbs and cracks and holds speed better, at the cost of a little torque.
Q: Is it hard to start from a standstill?
A: Being sensorless, it wants a push before the controller can read rotor position. That is the trade for having no fragile sensor cable.
Q: Can I replace the urethane?
A: Yes. The PU sleeve is a wear part and replacing it is the reason the motor can outlive several sets of wheels.
Q: Will it fit my existing trucks?
A: Fitment depends on your truck axle diameter and hanger geometry. Send a photo of your truck setup and we will confirm before you buy.
Q: What battery should I run?
A: A 10S or 12S pack is the usual pairing for a 24 to 36 volt system. Match your controller current to the pack's continuous discharge rating.
Q: How much does one motor add in weight?
A: Hub motors put the mass in the wheel, which is why dual drive feels heavier to carry but more planted to ride. Weigh your target build before choosing.
Q: Does it brake, or only coast?
A: It brakes electronically through the same windings, with force that scales with speed. Controller settings decide how aggressive that feels.
Q: Which wheel sizes are in stock?
A: Both 70mm and 90mm configurations are listed, along with single and dual drive options.
The EastSupplier Promise
We ship from the warehouses closest to you, confirm stock before the order is packed, and answer technical questions in plain English. If a part does not fit the machine you told us about, we make it right. Cross-border sourcing should feel like working with an engineer, not a marketplace.
