HOW TO CHECK THE COMPATIBILITY OF YOUR BIKE WITH A WHEEL MOTOR KIT?
THE REAR WHEEL ENGINE
For a rear-wheel engine, two things must be remembered. First, the type of attachment of the original wheel to the frame, then the wheel center distance (inner width of the frame). As for the attachment system, there are nowadays two major standards in the bicycle world. The first is called a "quick release" fastener. Easily recognizable because the frame mounting nozzles are open (U-shape) as shown in the photo below.
Next, you need to measure the center distance of the frame at the level of the rear wheel; to do this, you need to disassemble the wheel and measure the frame center distance as shown in the photos below. The European standard is 135mm, however some bikes may have a larger center distance (fat bike for example) and in this case, not all engines will be compatible. To sum up, if your bike has a 135mm axle spacing and a quick coupler, it will be compatible with most of our rear-wheel engines, such as the Touring, Road, Enduro, Freeride, Speed, MAC...
PARTICULAR CASE OF BICYCLES WITH THROUGH-AXLE
Some mountain bikes, road bikes, and Gravels after 2013 have a rear wheel axle called "traversing". The axle passes through the wheel hub and is screwed directly into the frame (as on motorcycles). This system is distinguished by completely closed frame attachments as shown in the photos below.
If you have this type of frame, the center distance is certainly 142mm or 148mm (Standard BOOST). In this case, only the "thru-axle" rear wheel motor kit will be compatible with your bike.
THE FRONT WHEEL ENGINE
If you want to install a front-wheel motor on your bike, you will need to measure the fork center distance. The European standard is 100mm. So you need to measure 100mm of inside width between the fork tips as in the photo below. If your bike is equipped with a traditional fork, all our front wheel motor kits will be compatible.
WARNING
If your fork is an MTB fork with a through axle as shown in the photo (10x110mm, 15x110mm, 20x110mm axle...), no front wheel motor will be compatible with your fork and you will therefore need to choose a rear wheel motor or a crankset motor.
