If you own a Brompton folding bike and dream of effortlessly conquering mountain trails or expanding your urban adventures, then the GreenPedel GP-G18 Internal Rotor E-Bike Kit is the perfect upgrade for you. Designed specifically for Brompton bikes, this 36V 250W conversion kit combines cutting-edge technology with Brompton's signature portability to transform your manual ride into a powerful e-bike experience. Let's explore what makes this kit stand out.
Unlike conventional hub motors, inner rotor motors have a compact design and high power density. Their rotors are located inside the stator, reducing inertia and enabling fast acceleration, while maintaining a lightweight profile (the motor system weighs just 6kg). This ensures that your Brompton retains its trademark foldability and flexibility even after electrification.
2. Perfect fit for Brompton bikes
The kit's motor has been designed with Brompton's unique geometry in mind, ensuring easy installation without compromising the structural integrity of the bike. The understated design maintains a clean aesthetic and retains the sleek look of the Brompton.
3. Intelligent and customizable performance
- 25-28 km/h Auxiliary Speed: Cruise comfortably at city-appropriate speeds to comply with road regulations.
- 12 Magnet PAS Sensor: Provides smooth pedal assist response to mimic a natural riding feel.
- Dual Throttle Option: Choose between thumb throttle or twist throttle for intuitive control.
- Waterproof Wiring: Withstands rainy day commutes or impromptu adventures.
4. Battery flexibility
While the kit itself does not include a battery, it supports 24V/36V configurations, allowing you to pair it with a lightweight lithium battery (5-16Ah battery recommended). The battery can be mounted on the rear frame, keeping the Brompton balanced and foldable.
5. Trusted safety and compliance
The GP-G18 is CE and EN15194 certified and meets stringent safety standards. The integrated electronic brake sensor (MS-02) ensures rider safety by cutting off motor power immediately upon braking.
