Description

500W MTX E-Bike Conversion Kit – Rear Hub Motor for 27.5" and 29"

The first step beyond the legal limit – the 500W brushless gearless direct-drive motor delivers nearly double the torque of the 250W, firm acceleration and sustained power on gradients up to 18%. A complete kit for a genuinely high-performance e-bike, ready to fit on 27.5" and 29" wheels with no frame modifications.

500W 36V / 48V / 52V Rear Hub 27.5″ / 29″ Direct-Drive ~8 kg

The 500W kit is the natural choice for riders who feel the limits of a 250W motor – steeper hills, headwinds, or mixed routes that demand extra power in reserve. Nearly double the torque of the base variant means firmer acceleration off the line and a feel much closer to a true performance e-bike, without giving up the quiet reliability of the direct-drive motor.

What's Included in the 500W Kit

500W brushless gearless direct-drive motor, built into the rear rim
48V 22A controller with 18 MOSFETs, dual Hall / non-Hall mode
SW900 LCD display with speed, battery level and ride data
Full-twist throttle with battery indicator
12-magnet PAS sensor
Brake levers with motor cut-off sensor
Complete wiring harness and mounting hardware

Available for 27.5" and 29" wheels. Double-wall aluminium rim, 12G spokes, standard 135mm rear axle.

Direct-drive motor: no gears, no wear

The gearless direct-drive motor has no gears or moving mechanical parts – force is transferred magnetically straight from the stator to the rotor. Completely silent operation under 60 dB, zero mechanical wear and a practically unlimited service life. At 500W continuous power, the motor maintains consistent performance on gradients of 15–18%, under load and during extended use, with no thermal limiting. Sealed casing for use in any weather.

22A dual-mode controller – added reliability

The 48V 22A controller with 18 MOSFETs runs primarily on Hall sensors for smooth start-up and precise response. If the sensors fail, it automatically switches to non-Hall mode – the motor keeps running without interruption. The brake levers cut power to the motor instantly for safe stopping.

Worth knowing: 500W exceeds the standard 250W legal limit for pedal-assist e-bikes in the EU – check current local regulations on registration before riding on public roads.

Who It's For

Hilly Commutes

For commuters with mixed routes or frequent climbs, where a 250W kit would start to feel underpowered.

Cargo Bikes

For riders carrying loads or using a cargo bike who need the extra torque on tap.

Upgrade from 250W

The natural next step for anyone wanting to upgrade from a 250W kit to more power and a firmer response.

Compatible with controllers and accessories from our range for custom configurations.

Recommended Battery

The kit is optimised for 48V, but also compatible with 36V/52V. We recommend the 48V 17.5Ah Downtube battery – mounted on the down tube, 50–80 km range, built-in USB port and key-lock security. Other compatible options are available in the eBike Batteries category.

Parts and Other Kits

Spare parts and accessories are available in the eBike Parts section. For a full comparison with the other power options, see the entire conversion kits range – from 250W up to 3000W.

Frequently Asked Questions About the 500W Kit

How much does range increase compared to a 250W kit?

Consumption at 500W is higher over the same distance compared to 250W, but the real-world range difference depends on riding style and terrain. With a 17.5–20Ah battery, estimated range is roughly 50 to 80 km.

Can I use this kit with a 36V battery?

Yes, the controller is also compatible with 36V, but optimal performance (torque and top speed) is achieved at 48V, the voltage the kit is optimised for.

Do I need to register a 500W kit?

500W exceeds the standard 250W limit for pedal-assist e-bikes in the EU. We recommend checking current local regulations before riding on public roads.

How much more torque does it have compared to the 250W kit?

The 500W kit delivers nearly double the torque of the 250W, with sustained performance on gradients of up to 18%, compared to the moderate gradients handled by the 250W version.

Does this kit work with 26" wheels?

The 500W kit is only available for 27.5" and 29" wheels. For 26", the 250W version offers this size.
