E-bike conversion kit FAQs
Cyclotricity makes three conversion kits, and the best one depends how and where you ride:
- Front-drive 250W (from £150) — easiest to fit, most universally compatible; ideal for commuting and everyday riding. Our best-value, best-selling kit.
- Mid-drive 250W (from £250) — drives through your bike's gears for the most natural feel and best hill-climbing; great for hilly routes.
- Rear-drive 1000W (from £180) — direct-drive for maximum torque and speed.
Not sure? For most UK riders we'd point you to the Cyclotricity Front-Drive 250W — the easiest fit and best value. Tell us your typical ride and we'll confirm the right one.
In most cases, yes. Three things decide fit:
- Wheel size — the front kit covers 20", 26", 27.5" and 700c/28"/29er; the rear 1000W covers 27.5" and 700c/28"/29er.
- Frame and forks — front kits need standard ~100mm fork dropouts; rear kits need standard 135mm rear spacing; the mid-drive needs a square-taper 68/73mm bottom bracket.
- Brakes and gears — works with both disc and V-brakes; the rear kit needs a freewheel (a cassette needs an adapter).
A torque arm is included where needed. Standard hybrid, mountain, commuter or road bike? A Cyclotricity kit will almost certainly fit — and if you're unsure, send a photo of your dropouts and brakes and we'll confirm before you buy.
Cyclotricity kits start at £150 (front-drive 250W), with batteries from £99 — and your total depends on the battery range and spec you choose. Even a fully-kitted conversion comes in well under the £1,000–£3,000+ of a comparable new e-bike, and you keep the bike you already trust.
Cyclotricity also starts lower than other kit brands (from £150 vs ~£190 Yose Power, ~£465 Swytch), with more battery and power choice.
Yes — a conversion is road-legal as long as the finished bike meets the EAPC rules: motor 250W or less, assistance that cuts off at 15.5mph, the motor only assisting while you pedal, and the rider 14 or over. Cyclotricity's front- and mid-drive 250W kits are built to meet these limits — no licence, tax, registration or insurance needed.
The 1000W rear kit exceeds them and is for off-road use.
