The majority of bikes are compatible with our rear hub motor kit. However, a few checks should be made before any purchase: rear dropout spacing, wheel size, cassette type, and available space for the battery.
Good news: all our wheels are compatible with disc brakes as well as rim brakes, for maximum integration on your bike.
Coming soon: we will soon be offering a version with a 12 mm thru-axle, compatible with 142 mm and 148 mm standards, ideal for modern bikes (MTB, gravel, etc.).
There are two types of rear wheel mounting:
- Quick Release: classic standard in 135 mm, very common on city bikes and older mountain bikes.
- 12 mm Thru-axle: modern, stiffer, and more secure standard, used on recent bikes (mountain bikes, gravel, disc road).
Les axes traversants offrent une meilleure rigidité et un maintien plus sûr de la roue, notamment avec les freins à disque :contentReference[oaicite:1]{index=1}.
Coming soon: we will soon offer a motor compatible with 12 mm thru-axles in 142 mm and 148 mm, suitable for modern bikes.

Which mid-drive motor to choose?
The power of the kits and the battery capacities depend on the use. You must also take into account the technical possibilities with your bike. Discover below some recommendations and the main different power levels.
The 500w motor is the best seller in Switzerland because it provides all the necessary power while remaining within the legal framework.
The 750W and 1000w motors are only intended for use on private property and are prohibited on public roads and paths.
| Power | Max torque | Main use |
|---|---|---|
| 250W Kit | 80Nm | On flat ground for rides without elevation changes |
| 350W Kit | 90Nm | Ideal for flat, leisurely rides |
| 500W Kit | 110Nm | Suitable for daily use and leisurely rides, capable of hauling loads on any terrain |
| 750W Kit | 130Nm | Very powerful motor for rides such as mountain biking |
| 1000W Kit | 160Nm | Powerful motor for hauling heavy loads |
Which battery to choose?
Before choosing a kit, it is essential to check if installing the battery on your frame is technically feasible. In 99% of cases, we have suitable solutions, but three elements must be taken into account: technical feasibility, the capacity required according to your needs, and aesthetics.
We always ensure that the battery integration alters the design of your bike as little as possible.
If in doubt, do not hesitate to contact us. We will advise you in order to choose the best option for your bike.
All our batteries are delivered equipped with Samsung cells and a high-performance, quality BMS.
Lightweight battery, only 2kg, but note that 36V/10Ah provides limited range, though sufficient for the rear wheel motor
Battery to be installed on the bottle cage screws, the most suitable battery for all bikes that have the space for integration. By clicking on the photo, you will see the dimensions of the battery.
Rack battery, this battery can be installed on any bike with fixings in the frame for installing a rack. This battery is only recommended in the case of bikes that are not compatible with the bottle cage battery, because the center of gravity is off-center and may present discomfort, especially if you still want to put panniers or a basket on it. Also note that not all panniers are compatible with this model.
Saddlebag battery, this battery can be installed on all bikes on the market. It is mainly recommended in cases where other battery models do not work on your frame. It is custom-made according to the customer's wishes and the technical possibilities of the bike.
