Engineered for riding purists and challenging terrains. Upgrading your rear wheel delivers superior traction on wet or loose gravel, provides powerful hill-climbing torque, and mimics a natural "pushing" acceleration feel. It seamlessly integrates with your existing cassette while preserving your front fork's agile steering.

💡 If your bike specs fall outside the standard options above, or if you're unsure how to measure, check the options below—our team is here to help!
1️⃣ Standard Setup (Direct Order):
If your bike specs match the standard cards above, you're all set! Just fill them in at checkout for a guaranteed seamless fit.
2️⃣ Special / Non-Standard Setup (Custom Solution):
Have a non-standard bike (e.g., 130mm QR road bike dropouts, custom axle width, or unique rim sizes)? Simply enter your actual measurements in the order notes. Our engineers will tailor a solution for you.
3️⃣ Unsure About Your Specs? (Free Expert Help):
Don't know how to measure your axle width or identify your cassette? No problem! Send us a photo or model name of your bike, and our 1-on-1 expert support will help you confirm compatibility before ordering.
Best for hilly routes, off-road trails, and wet surfaces where maximum rear-wheel traction is essential.
Delivers power from behind, closely replicating standard cycling dynamics while keeping front steering light and responsive.
Ideal for bikes with suspension front forks or high-torque setups — rear dropouts offer greater structural strength for motor loads.
⚡ Maximum Traction & Superior Climbing
Rider weight rests directly over the rear wheel, eliminating power spin-out on steep hills, wet pavement, or loose gravel.
🎯 Natural Handling & Low-Profile Design
Delivers a smooth, natural rear-push acceleration while the motor tucks neatly behind the rear cassette and brake disc.
🚲 Suspension-Safe & High Torque Capability
Leaves delicate or suspension front forks untouched, allowing for higher motor torque and smoother overall power transfer.
🛠️ Slightly More Complex Installation
Requires transferring your existing rear cassette or freewheel and adjusting rear derailleur alignment during setup.
🔧 Extra Steps for Rear Flat Repair
Fixing a rear puncture requires disconnecting the waterproof motor cable connector before removing the rear wheel.
⚙️ Pre-Order Specs Verification
Requires verifying your rear dropout width (e.g., 135mm QR vs. 142mm Thru-Axle) and cassette speeds prior to ordering.
Dropout 135mm & slot width 10mm
Thru-Axle 142/144mm
Dropout 130mm
Slot width 9mm
💡 If your bicycle uses thru-axles, be sure to select a thru-axle kit. LVBU's KN, KF, KH, and KD series e-bike conversion kits all have thru-axle versions.
💡 Please note that the same English size may refer to different wheel sizes. For example, the 20-inch 406 and the 20-inch 451 are both 20 inches, but they are two completely different wheel sizes.
Important: When choosing wheel size, please try to use ISO/ETRTO sizes to ensure you choose the correct wheel size.
Rear wheel setups require precise compatibility with axle widths and cassette and drivetrain specs. To help avoid order mistakes, every order on DIYebicycle is manually reviewed by our engineering team prior to dispatch. If any incompatibility is detected, we will contact you to resolve the issue before shipping.
