WEEROCK Tricycle Rear Axle Conversion Kit

The WEEROCK kit supports 20″, 24″, and 26″ frames with a single speed or seven-speed option. It uses a 5/8 inch (15.8 mm) axle designed for hollow-hub wheels and includes a rear band brake setup. Best for riders who want a single- to multi-gear upgrade on mid-sized pit bike frames and who prefer a compact, straightforward rear axle solution. Choose this if you value broad wheel compatibility and a simple braking configuration. Caution: ensure your wheel hubs are hollow for proper fitment.
Trike Rear Axle 7-Speed Conversion Kit

This kit is designed to fit 20″, 24″, and 26″ adult trikes with seven speeds and a 15 mm axle. Built on high carbon steel, it supports hollow-hub wheels and delivers a versatile gearing range for varying terrain. Best for riders who want more hills and longer rides without sacrificing stability. Better for those who already own hollow-hub wheels. Limitation: axle size is fixed at 15 mm, so verify compatibility with your bike’s bearings before purchasing.
SUN BICYCLES Single Speed Coaster Brake Kit

Sun Bicycles offers a dedicated single-speed coaster brake trike conversion. It is suitable for trike builds that aim for a classic coaster brake experience with simple maintenance. Best for riders who prioritize a low-maintenance, nostalgia-inspired braking system. Caution: some users report vibration during braking, which may not indicate a defect but is a characteristic of this design.
Lowrider Bike Trike Conversion Kit 7-Speed

This kit is listed as a seven-speed option with a compact profile and a mushroom-style stem, suitable for lowrider-inspired builds. Best for riders seeking a stylized, customizable trike with extra gearing. Choose this if you want a bold black/green color accent and a model that emphasizes form as well as function. Limitation: product description focuses on style features; verify gearing compatibility with your existing drivetrain before purchase.
Throttle Grip Kit for Pit Bikes

The throttle grip and bent-cable set is designed for 7/8″ bars and broad compatibility with 50cc to 250cc dirt bikes and pit bikes. Best for riders who want to add or replace throttle control during a trike conversion, or who need a flexible upgrade for bar-mounted controls. Caution: this is a throttle accessory rather than a complete drive kit, so a compatible drivetrain is required to complete the build.
Buying Guide
- Compatibility basics: Check wheel size (20″, 24″, 26″), axle diameter (commonly 5/8″ or 15 mm), and whether your hubs are hollow for proper mounting.
- Gear options: Decide between single-speed and multi-speed (7-speed) setups based on terrain, use-case, and maintenance tolerance.
- Braking system: Coaster brake vs. band brake configurations affect stopping feel and maintenance. Consider your preferred braking style and local riding conditions.
- Material quality: High carbon steel and robust hardware improve durability for casual cruising and longer rides.
- Installation effort: Some kits are straightforward rear-axle swaps; others may require hub compatibility checks or additional parts (bolts, spacers, brake connectors).
- Weight and balance: Adding a rear axle and trike components shifts bike dynamics. Ensure your center of gravity remains manageable for stable handling.
- Aesthetic and customization: Some kits emphasize style (color, mushroom stems, black/green accents) as part of the upgrade, not just function.
FAQ
- What wheel sizes do these kits support?
Most kits target 20″, 24″, and 26″ frames; verify wheel type (hollow-hub vs solid) and axle fitment before purchase. - Do I need special tools to install these kits?
Many rear-axle conversions are straightforward, but some may require basic hand tools and possibly spacers or adapters depending on your bike’s hubs. - Is a 7-speed option worth it for a pit bike trike?
Seven speeds provide more gearing flexibility for hills and varying terrain, but require compatible shifters and chain setup. - Can I mix-and-match parts from different brands?
Mixing components is possible but risks misalignment or incompatible hubs. Prefer kit-compatible parts or confirm compatibility with the seller. - What braking type is easiest for beginners?
Coaster brakes are simple and low-maintenance, while band brakes offer more direct braking feel with proper adjustment. - Are these kits safe for everyday use?
All kits are designed for use on standard bikes with proper installation. Always inspect fasteners, brakes, and alignment before riding.
