Our take on the Motor & Battery Kit

A complete mid-drive e-bike conversion kit: motor, battery, charger, battery cradle, larger Intuition color display, throttle, 170mm cranks, extension wire, display gimbal and installation sheet. The motor sits at the frame between the wheels, so you and the motor share the bike's gearing and both spin faster when you downshift for a climb. The Bafang350 option is a detuned Bafang750 built for riders who want modest, reliable assist that won't stress an internally geared hub. It suits riders converting a donor bike who want a full kit in one box rather than sourcing parts separately.

Pros
  • Everything for a conversion is included: motor, battery, charger, cradle, display, throttle, cranks and wiring
  • Mid-drive placement keeps weight between the wheels and eases tire changes
  • Motor and rider share the bike's gearing, which helps on climbs
  • Multiple power levels changed with a button press
  • Color display included
  • Bafang350 is a detuned Bafang750, so the motor runs well within its design
Cons
  • Battery choice depends on frame size, so buyers must match it themselves
  • Mid-drive kits add wear to the bike's drivetrain
  • Installation needs tools and some mechanical skill
  • Detuned 350W output is modest for strong riders or steep terrain

What reviewers say

  • 4.3 / 5103 ratings

Rated 4.3 out of 5 across 103 ratings. Owners treat it as a solid complete conversion kit, with the included parts and mid-drive climbing behavior standing out; the main friction is matching the battery to the frame and the install itself.

About the Motor & Battery Kit

This is a complete mid drive conversion kit for a bike. Every kit includes a motor, battery, charger, battery cradle, larger Intuition color display, throttle, 170mm cranks, extension wire, installation sheet and display gimbal.

The mid drive motor mounts to the frame between the wheels, which improves balance and makes tire changes easier. Both you and the motor drive the chain, so you both use the gearing. When you downshift on a hill, you and the motor spin faster. Bafang and CYC motors have multiple power levels that you change with a button.

The Bafang350 is a Bafang750 detuned to 350W, so the motor works well below what it was designed for. The CYC Photon Gen 2 and X1 Pro Gen 4 can be programmed from a smartphone and use an open CANBUS system. They use a sprag clutch and combine torque sensing with speed sensing, so the motor delivers more power the harder you pedal.

Questions and answers

What is included in the kit?
Motor, battery, charger, battery cradle, larger Intuition display, throttle, 170mm cranks, extension wire, display gimbal and an installation sheet.
