E-bike conversion kits
You’ll find kits that turn a regular bike into an e-bike, with a mid-drive motor or a rear or front hub motor, rated at 250 to 750 W and 36 to 52 V. Bike type, rim size and whether you already have a suitable battery matter most. Kits rated above 250 W are not road-legal under EU rules.

For hills, mid-drive kits are a good fit; they replace the 68–73 mm bottom bracket. The motor drives the chain, so it also uses the gears. They include a 36, 42 or 44-tooth chainring and, depending on the version, a cadence sensor or a torque sensor.
Easier to fit are hub motor kits. The motor is laced into a 26, 27.5, 28 or 29-inch rim, so you simply swap the whole wheel. Rear kits are mostly for cassettes, some for screw-on freewheels, and front motor kits are available too. For some, the manufacturer quotes 65 Nm of torque.
The kits include a display, some with Bluetooth, usually a throttle and often brake sensors that cut the motor when braking. Only a few kits with a battery (624 to 1440 Wh) are available; the rest need a battery with the same voltage. In the EU, only an e-bike up to 250 W with pedal-only assistance up to 25 km/h counts as a bicycle; stronger kits and kits with a throttle may fall into another vehicle category.
How we rank results
We determine the order of offers in search results and in category listings automatically, according to the rules below. No seller is given priority in the ranking, and it is not possible to pay us for a better position.
Search (default sorting “Relevance”): we show offers that match the search term, including those with a small deviation or only a partial match. Their order depends most on how popular the offer is with customers. If you have accepted cookies, the next biggest factor is which categories and offer attributes you have viewed during your current visit. It also matters how popular the offer is for that search term, how closely it matches the term and how popular its category is for that term.
Categories (default sorting “Best Sellers”): the offers that sell the most appear at the top.
Sorting by price: if you choose Price: Low to High or Price: High to Low, we sort by price including VAT only.
