Sun 3-Speed Coaster Brake Hub Conversion Kit
This kit adds three gear options with a front drive cog (21T) and rear transfer (22T) plus a 24T axle drive cog. Best for riders who want a straightforward, low-maintenance gearing setup paired with a traditional coaster brake. Suitable for adults with standard trikes that support a hub conversion. A limitation to note is the fixed gear spacing, which may require wheel and chain adjustments to optimize shift performance.
WEEROCK 20″/24″/26″ Tricycle Rear Axle Conversion Kit
This conversion kit supports 20, 24, and 26 inch trikes and offers options for 1-speed or 7-speed setups. It uses a 5/8 inch axle diameter and fits hollow-hub wheels, with a band brake integration. Best for riders needing a versatile upgrade across multiple wheel sizes and who prioritize a compact, single-piece axle design. Choose this if you ride a hollow-hub wheel and want flexible gearing; avoid if your trike uses a solid axle or non-hollow hubs.
WEEROCK 20″/24″/26” Tricycle Rear Axle Conversion Kit (Black)
This black variant mirrors the same 20/24/26 inch compatibility with a 5/8 inch axle and hollow-hub wheel fitment. It’s best for riders seeking a low-profile, visually cohesive upgrade that blends with black components. A potential limitation is that some trike models may require additional hardware or alignment tuning for 7-speed setups.
SUN BICYCLES Single Speed Coaster Brake Conversion Kit
This single-speed coaster brake kit offers a cost-effective upgrade path for trike owners seeking a simple, reliable conversion. The kit includes a coaster brake mechanism suitable for straightforward commuting or casual rides. The key caveat is the vibration noise reported during braking, which is not considered a defect by the manufacturer but may influence rider comfort on certain routes.
Trike Rear Axle Conversion Kit — 7 Speed
This kit supports 20”-24”-26” adult trikes with a 7-speed setup and a 15 mm axle size. It’s made from high-carbon steel, emphasizing durability for frequent riders. Best for riders who want a robust, multi-gear upgrade that withstands regular use. A limitation is the heavier steel construction, which can add some weight to the bike during installation and use.
Buying Guide
What should you consider when choosing a 3 speed trike conversion kit?
- Wheel size compatibility: Confirm 20″, 24″, or 26″ compatibility and whether you need a kit that covers multiple sizes.
- Gear options: Decide between single-speed, seven-speed, or three-speed setups based on terrain and riding style.
- Hub and axle type: Check if your trike uses hollow-hub wheels and the axle diameter (commonly 5/8 inch or 15.8 mm) to ensure a proper fit.
- Braking compatibility: Coaster brakes vs. band brakes impact installation and stopping power on the upgraded system.
- Material and durability: High-carbon steel offers strength, while lighter alloys may reduce weight but trade durability.
- Installation effort: Some kits require wheel removal, realignment, or chain adjustments; ensure you have the tools and time.
Practical tips for a smooth upgrade
- Measure your trike’s rear axle and wheel hub to match kit specifications exactly.
- Plan for chain length adjustments when changing gear configurations to prevent sag or slack.
- Check brake compatibility and test braking in a safe area after installation.
- Keep spare spacers and fasteners from the kit during initial setup for easier troubleshooting.
