Hub Motors

36V 350W Geared Front Hub Motor Wheel Kit (generic)

A small geared front hub is the simplest conversion there is: drop the wheel in the fork, mount a battery and controller, and you have an assisted bike without touching the drivetrain. The 350W geared units are light, freewheel without drag, and climb moderately well thanks to internal reduction gears. Listings are generic, so match wheel size, fork dropout width (usually 100 mm), and make sure the kit includes a torque arm or buy one; front dropouts on aluminum and suspension forks do not tolerate motor torque well without one.

Key considerations

  • Use a torque arm; never rely on the dropout alone, especially on aluminum or carbon forks
  • Front-wheel drive loses traction on wet or gravel climbs
  • Wheel size must match the fork and tire you plan to run
  • Check the controller and display that come with the kit — they are often basic

Pros

  • Easy install
  • Light and drag-free
  • Inexpensive

Considerations

  • Front traction limits
  • Generic controller/display
  • Gears wear eventually

E-Bike Batteries

36V 10Ah Hailong Downtube Battery (generic)

Many budget 36V e-bikes and conversion kits use an unbranded Hailong-case battery, and when one dies the replacement is usually another unbranded Hailong-case battery. The listings all look alike, so the job is to match four things: 36V nominal (42V fully charged), the correct Hailong case generation, the discharge connector on your cradle, and a BMS that can feed your controller. A 10Ah pack is a modest capacity, suited to 250W–500W bikes that see neighborhood and short-commute duty. Choose a listing that states the BMS amp rating and ships with a charger.

Best for: Replacing a worn-out 36V Hailong pack on a budget commuter or folding bike · 36V 250W–500W conversion kits with a Hailong cradle · Riders who only need 15–25 miles of assisted range

36V/48V 15A Dual-Mode Controller for 250W–350W Hubs (generic)

Small folding and commuter e-bikes with 250W–350W hub motors use compact 15A controllers that tuck into a frame cavity or under the rack. The dual-mode versions can run with or without hall sensors, which makes them forgiving when a hall wire has failed. Many budget bikes use a controller like this paired with a simple LED or LCD, so the catch is always the display protocol and the connector set. Buy one when your bike's original is out of stock, and be prepared to swap the display and throttle to matching parts if the protocol is unknown.

Best for: Small-motor folding and commuter e-bikes · Replacing a controller in a tight frame cavity · Bikes with a suspect hall sensor (dual-mode runs sensorless in a pinch)
