This kit is an affordable entry point for converting a standard bike into a three-wheel rider. The assembly focuses on durable steel construction and straightforward installation for hobbyists and DIY enthusiasts.
24V Dual Drive Motor Wheel Kit
This complete kit includes two wheels, two motors, and a thumb throttle with battery indicator lights and a button switch, making it a turnkey upgrade for scooter or small cart builds. Each motor delivers up to 250W, providing reliable starting torque and steady propulsion. The kit emphasizes stability and ease of installation, aiming to reduce the need for additional compatible components. It is well-suited for riders seeking electric-assist upgrades that improve uphill performance and reduce physical effort during longer rides.
Trike Rear Axle 7 Speed Conversion Kit
The Trike Rear Axle 7 Speed kit is designed for 20″, 24″, and 26″ adult trikes. It features a 15 mm axle (5/8 inch) and is compatible with hollow-hub wheels. The kit is crafted from high-carbon steel, emphasizing durability for higher-mileage setups. With a seven-speed option, riders gain versatile gearing that helps tackle varied terrains, from city streets to light off-road paths. It is targeted at riders who want a robust, performance-oriented conversion solution for everyday use.
Electric Scooter Hub Motor Kit
This hub motor kit includes dual 350W DC motors and a controller with a three-speed forward/reverse throttle, designed for electric scooter or go-kart conversions. The kit uses high-strength aluminum alloy, rubber, and copper for durable construction. It offers strong power output and stable performance, with a setup suited to riders who want significant propulsion without complicated wiring. The inclusion of reverse and speed controls supports versatile riding scenarios and safer maneuvering in tight spaces.
PEXMOR 20″ Front Wheel E-Bike Conversion Kit
The PEXMOR 20″ front-wheel conversion kit features a 36V 750W brushless motor, delivering a top speed around 20 mph on compatible frames. It supports 100 mm front dropout spacing and includes a three-mode controller with pedal assist system (PAS) and LCD display. The sine-wave controller is noted for higher efficiency and lower noise, and the PAS modes reduce rider fatigue by providing assistance when needed. This kit suits riders seeking a robust front-wheel enhancement with modern control features.
Buying Guide: Key Purchase Considerations
- Compatibility: Verify wheel size (20″, 24″, 26″, or 8″ for hubs) and axle standards (5/8″ or 15 mm) to ensure a proper fit with your frame and hub types.
- Power and Torque: Higher wattage motors deliver stronger acceleration and hill-climbing capability but may require better battery support and heavier builds. Consider the range between 250W and 750W for front vs. dual-motor configurations.
- Drivetrain Configuration: Decide between single-speed, multi-speed, or hub-mub setups. Multi-speed options add versatility for varied terrains but may require more complex installation.
- Installation Skill Level: Some kits are “complete” with throttles and controllers, while others require sourcing additional components. Assess your DIY comfort level before purchasing.
- Control Options: Look for throttle types, PAS (pedal assist) integration, and reverse functionality if you anticipate tight maneuvers or reverse parking needs.
- Safety and Braking: Ensure compatible braking methods (band brakes, mechanical disc, or integrated braking) align with your frame and wheel setup for reliable stopping power.
- Weight and Stability: Three-wheel configurations generally improve stability, but added weight in the rear or front hub can affect handling. Consider frame strength and load capacity.
- Maintenance: Brushless and gear-based motors have different maintenance demands. Check for availability of spare parts, batteries, and service options in your region.
- Battery Compatibility: If choosing electric kits, confirm voltage compatibility (24V, 36V, or higher) with existing or planned battery packs and chargers.
