The MHT70 HIGH TORQUE Motor is a high-torque hub motor supplied with its tubed split rims, designed to replace the original motors of large dual-motor scooters: Dualtron Thunder and Ultra, Bronco Xtreme, Nami Burn-E. 70 mm magnets, 10 mm² phase cables, 6000 W nominal: a motor built to be pushed to the limit by a high-performance controller.
Who is this for?
You want violent standing starts, strong climbing ability, or to ride fully loaded or with dual motors without ever feeling the motor struggle. Top speed is slightly lower than the HIGH SPEED version, but the responsiveness is incomparable.
Technical specifications
- Type: high-torque brushless hub motor (long winding: fewer RPM but much more torque, for sharp starts, climbs, and heavier riders)

- No-load speed at 60 V: 1718 RPM
- No-load speed at 72 V: 2062 RPM
- Phase cables: 10 mm²
- Nominal power: 6000 W
- Hall sensors: yes, compatible with VESC / 3Shul / original controllers
- Split rims: 6.5" tubed split rims, included
- Tires: 11", 12" or 13"
- Weight: approx. 8 kg
Compatibility
Supplied with 6.5" tubed split rims that open in two: tire changes are done without tire levers or struggle.
Fits on: Dualtron Thunder, Dualtron Ultra, Bronco Xtreme / Vnom, Nami Burn-E and compatible swingarm models.
Is your scooter not on the list? Our motors adapt to most machines on the market: the spacing and axle length can be adjusted with custom-machined axles and spacers (stainless steel axle kit, spacers), and we regularly adapt these motors to models not listed here. Send us a photo of the swingarm and the original motor with the measured swingarm opening: we will confirm feasibility before shipping.
What you need to consider around the motor
- Controller: this motor is only worth it with a controller capable of feeding it. A VESC controller (3Shul and compatible) controlled by our SmartDisplay allows you to adjust current and curves to get the most out of it; an original controller will work, but will limit the power.
- Wiring: 10 mm² phases require high-quality connectors (8 mm bullets) and a clean harness — see our braided sleeves and connectors.
- Rim and tire: split rims are included; plan for a tire and inner tube in the chosen size (11", 12" or 13").
- Ventilation: for intensive use or competition, our motor ventilation kit mounts on the cable-side flange and significantly improves cooling.
Options
Standard paint (black) or custom paint: specify the desired color in the order message, the motor is painted in the workshop before shipping (additional lead time of a few days).
Manufacturing and warranty
Each motor is checked in our Lyon workshop before shipping. We ride with these motors in competition, and feedback from our riders is used directly to evolve the range. Fast shipping in France and Europe, technical support via email for controller selection and tuning.
Frequently asked questions
What is the difference between MHS and MHT?
Same motor, two windings: MHS (HIGH SPEED) for top speed, MHT (HIGH TORQUE) for torque and acceleration. On a Thunder or a Nami for road use, the torque version is often the most pleasant; on the track, the speed version.
What tires do the split rims accept?
11", 12" or 13" tubed tires. The split rims separate into two, which makes changing tires much easier than with a one-piece rim.
Can I install it myself?
If you have already replaced a scooter motor, yes: it is a direct replacement for the original. Otherwise, our workshop offers installation (installation package available in the shop).
