Loopwheel fitting guides

Will loopwheels fit my wheelchair?

Loopwheels fit the vast majority of manual wheelchairs. If you are in doubt, phone or email us.

We make 24″ and 25″ loopwheels for wheelchairs. Our wheels have ½ inch bearings to fit standard ½ inch quick release axle pins. This is the most common size on most wheelchairs.

Some wheelchairs take 12mm axles, and we can make loopwheels with this size axle bearing too. Let us know when you place your order please! (These are generally chairs from Scandinavian or German manufacturers).

We send a fitting guide with every pair of wheels. When you first put the loopwheels on the chair, you just need to check that there aren’t any bolts sticking out from the side of your chair that could rub against the wheels. This is not usually the case, but it does happen with some chairs and is not a unique problem to loopwheels. You should be able to prevent any rubbing by adding some washers to your axle, which will move the wheels out just enough to ensure there is clearance.


Will loopwheels fit my bike or trike?

There are 3 important factors as to whether loopwheels are suitable for your bike or trike.

1: Wheelsize

We only make 20” loopwheels for bikes and trikes. This is a bead seat diameter (BSD) of 406.

2: Width of the Drop-out centre

The “drop out centre” on a bike is the distance between the forks where the hub fits. People also refer to the overlock nut dimension: it’s basically the same measurement. Watch out to check your forks are wide enough for our hubs!

On the rear, it must be: 117mm for the 3 speed rear wheel or 135mm for the derailleur loopwheel.

On the front, it must be: 100mm

3: Clearance space above the wheel.

This is to allow space for the loopwheel’s suspension to function. As the wheel hits a bump, the wheel moves up towards the frame. You need a minimum of 35mm from the top of the tyre to the underside of the fork (or any other part of the bike frame). If there is less than this 35mm space, your wheel could hit the frame causing it to brake. This is important! If you decide the fit thicker tyres to your loopwheels, watch out you don’t reduce this clearance gap!

If you have a Dahon Mu, you will need to replace the front fork with a wider one (100mm), and you can buy that from us. Dahon supply them to us for this exact purpose. We have forks for Terns too.

If your bike already matches these criteria, you’re good to go. If you’re not sure, drop us an email and we’ll try to help
