This selected black kit is designed to convert a compatible 20-inch bicycle into a front-wheel electric-assisted setup. It includes a 36V 250W brushless, gearless hub motor wheel and the main control hardware, but it is not a complete e-bike. You must provide a compatible 36V battery and charger, and the listing explicitly excludes the 20-inch tire.
What the selected kit includes
- 20-inch front motor wheel for the listed 20x1.75-2.125 tire size
- 36V 250W brushless gearless hub motor
- Controller and controller bag
- SW-810 LED display and thumb throttle
- Five-magnetic-point pedal-assist sensor
- Power-cutoff brake lever set, assembly accessories and an English manual
The seller’s package list also mentions a 7-speed flywheel. Because this is a front-wheel conversion, that line is not clear enough to treat as a useful rear-drivetrain component. Confirm its purpose with the seller before ordering.

Important limitations
This listing does not specify battery capacity, expected range, or a warranty. No exact independently verified UL certification was found for this listing and selected configuration. The product was not physically tested by PMCODE, and seller performance figures are claims rather than PMCODE measurements. The description says the product is not waterproof and should not be ridden in rain. A torque arm is not shown as included or verified, so front-fork security and installation requirements need particular attention.
Buying and installation checks
- Measure the bicycle’s front-fork opening and confirm it is compatible with the approximately 100 mm axle spacing.
- Verify the frame accepts the 20-inch wheel and the 20x1.75-2.125 tire size; the tire itself is excluded.
- Confirm whether your existing brake setup is compatible with the supplied power-cutoff levers.
- Choose a compatible 36V battery and charger separately, checking mounting space, connectors and electrical specifications.
- Ask the seller to clarify the listed 7-speed flywheel and whether a suitable torque-arm solution is required.
Overall, this is a conditional option for a buyer who can verify fork fit, braking, battery compatibility and safe motor retention before installation.
