Buying Guide
Power and Torque
Higher wattage (750W–1000W) generally provides stronger torque and faster cruising on hills and rough terrain. Choose based on intended use: city commuting may be comfortable with 500W, while mountain or cargo applications benefit from 750W or 1000W for sustained climbs and aggressive acceleration.
Bottom Bracket Compatibility
Most mid-drive kits target 68-73mm BBs, with some extending to 85-125mm. Measure your bike’s BB width and inner diameter accurately. If your frame is nonstandard or uses an unusual BB, verify compatibility or consider adapters and longer spindle options.
Controller and Display
CAN bus and Tong-sheng communication protocols provide reliable diagnostics and smoother integration with displays. Determine whether you want an LCD display for real-time metrics or a ride with minimal electronics. Some kits offer optional displays or USB programming for advanced users.
Drivetrain Interaction
Mid-drive kits leverage your bike’s chainring and gears, which improves efficiency but can stress the drivetrain. Ensure you have a compatible chainring size and inspect chain wear, rear derailleur compatibility, and chainring teeth count for harmonious shifting and durability.
Installation and Accessories
Common kits include motor, controller, throttle, brake levers, sensors, and a chainring. Check whether a battery is included or sold separately, and consider required tools such as bottom bracket tools and torque wrenches. Some kits offer included USB cables and extension harnesses for easier wiring on complex frames.
Reliability and Support
Well-documented kits with widespread consumer use tend to have better support ecosystems and more readily available spare parts. Look for clear warranty terms, replacement parts availability, and accessible customer service to minimize downtime during maintenance or upgrades.
