Whether you’re retrofitting an existing bike or building a custom trike, the right conversion kit can add reverse capability, improve load handling, and broaden riding options. This guide highlights five solid options for shaft-drive motorcycles and related setups. Each pick is explained for who it’s best for, plus practical considerations to help you compare at a glance.
Buyer quick reference: the top picks focus on reverse gear functionality, rear axle compatibility, and multi-speed configurations. Ideal buyers include DIY enthusiasts converting bikes to trikes, riders seeking easier maneuverability for tight spaces, and hobbyists building custom three-wheelers for street use or light off-road use. The following table summarizes key points for fast comparison.
| Product | Best For | Main Benefit | Limitation |
|---|---|---|---|
| Transmission Reverse Gearbox (150-300cc) | High-torque bikes | Forward and backward gear conversion | May require mounting adjustments |
| Trike Rear Axle Kit 7 Speed | Adult riders with multi-speed needs | 7 speeds for varied terrain | Frame compatibility varies |
| Transmission Reverse Gearbox (100-150cc) | Smaller engine builds | Reliable reverse with compact design | Limited to engine size stated |
| WEEROCK Tricycle Rear Axle (7-speed) | Standard adult trikes | Single/7-speed options | May require framing adjustments |
| Motorcycle Transmission with Reverse | Broad bike compatibility | Reverse gearbox for 4WD and motorcycles | General part variability |
Transmission Reverse Gearbox for ATV 150-300cc
This reverse gearbox is designed for larger engine setups in trike configurations. Best for riders tackling steeper grades or heavier loads where a dedicated reverse reduces maneuvering effort. The kit provides forward and backward conversion, enabling easier parking and turning in tight spaces. Best for riders who want a straightforward reverse solution without extensive frame work. Caution: installation could require mounting and alignment adjustments to fit specific frames.
Trike Rear Axle, 7 Speed, 5/8 Inch Axle
This rear axle kit is suited for adult bicycles or motorcycles converted to trikes, offering a 7-speed option and a robust 5/8 inch axle. It’s best for riders who want more gearing flexibility for varying terrain without changing other major drivetrain components. Selection is favorable for those building a longer-lasting three-wheel ride where shifting range matters. Limitation: compatibility depends on frame width and mounting points; verify fit before purchase.
Transmission Reverse Gearbox for ATV 100cc-150cc
Designed for smaller engine builds, this reverse gearbox supports forward and backward operation in compact trike setups. Best for entry-level builds or riders prioritizing ease of installation and space efficiency. It’s an efficient way to add reverse without adding excessive drivetrain length. Caution: verify that engine displacement and frame tolerances match the gearbox’s specifications.
WEEROCK 20/24/26 Inch Tricycle Rear Axle Kit
This rear axle kit supports 20, 24, and 26 inch wheel configurations with single or seven-speed options. It’s best for riders who want a versatile trike build that can adapt to different wheel sizes and riding conditions. Better for standard adult tricycle conversions versus specialized racing builds. Caution: ensure wheel spacing and axle length match your frame design.
Motorcycle Transmission with Reverse
This reverse gearbox kit is aimed at broader compatibility with motorcycles and quad-style setups. It’s suitable for riders seeking a robust reverse mechanism that can fit a range of engine sizes and chassis types. Opt for this if you want a versatile reverse option for mixed-use builds. Limitation: installation complexity may vary by motorcycle model and existing transmission layout.
Buying Guide: Key Considerations for Trike Conversion Kits
- Engine compatibility: Verify engine displacement, power output, and mounting compatibility with the gearbox or axle kit.
- Frame and mounting: Check frame width, mounting points, and clearance around wheels, axles, and suspensions.
- Gear options: Decide between single-speed, multi-speed, or 7-speed configurations based on riding terrain and preferred cruising RPM.
- Reverse reliability: For frequent reversing needs, prioritize gearboxes designed specifically for forward/backward operation and tested fitment.
- Installation effort: Some kits require professional installation, modifications to existing frames, or custom brackets.
- Durability and materials: Look for robust steel or alloy components—especially for trikes carrying passengers or cargo.
- Maintenance access: Consider how easy it is to service bearings, seals, and gears once installed.

FAQ
- Do trike conversion kits require professional installation? Some do; check mounting points and tolerances.
- Can these kits be used on any motorcycle? Compatibility varies by frame design and engine size; verify model-specific fit.
- Is a 7-speed axle worth it for all riders? It’s beneficial for varied terrain and heavier loads, but adds complexity.
- Are reverse gearboxes prone to failure? Like all mechanical components, failures can occur without proper maintenance or fitment checks.
- Can I upgrade an existing setup to add reverse later? Yes, but ensure compatibility with current drivetrain and frame.
