Electric Bike Conversion Kits UK

Electric Bike and Cycle Conversion Kits

Shop an electric bike conversion kit for turning a suitable bicycle into an e-bike. Our UK range includes rear-hub motors, MTX wheel kits and battery-ready options for common 27.5-inch, 29-inch and 700C wheels.

Compare a 250W cycle conversion kit for a lower-power build with higher-powered 1000W, 1500W and 2000W kits intended for private-land or permitted off-road use. A safe electric bicycle conversion depends on the correct wheel size, dropout fit, brake clearance, motor voltage, controller and battery compatibility.

How to choose an electric bicycle conversion kit

• Wheel and frame fit: check wheel diameter, dropout width, axle type and available battery space.
• Electrical compatibility: motor, controller and battery voltage must match; verify connector types before ordering.
• Braking and condition: the donor bicycle, forks, brakes and drivetrain must be suitable for the extra weight and power.
• UK road use: the completed bicycle must meet the current GOV.UK EAPC rules if it will be used on public roads.

Frequently asked questions

Can I turn my current bike into an electric conversion bicycle?

Yes, when the donor bicycle is in good condition and the motor wheel, dropout, brakes, battery space, voltage and connectors are compatible. An electric conversion bicycle must also meet current UK EAPC requirements before it can be used as an ordinary e-bike on public roads.

Will every electric bike conversion kit fit every bicycle?

No. Wheel size alone is not enough: check dropout dimensions, axle type, frame and fork condition, brake clearance, battery space, voltage and connectors.

Can a cycle conversion kit be road legal in the UK?

It can be, but only when the completed bicycle meets all current EAPC requirements, including power, speed-assistance and pedal rules. Higher-powered builds are for private land or other legally permitted use.

Should I choose a kit with or without a battery?

Choose a kit with a compatible battery if you do not already own one. If buying separately, match the voltage, discharge capability, connector, mounting space and controller requirements.

For public-road use, check why a controller limit does not necessarily change a motor's continuous rating and why disabling a throttle does not solve a separate power-rating issue.
