MXUS XF08C / XF08 advice

[Lillebo]

Hi

I have a question about the XF08C 250W rear hub drive.

My plan is to fit it on a bike with a dropout measurement of 135mm, even though the axel measurement is about 144mm as shown on these drawings

according to this thread

https://www.pedelecs.co.uk/forum/threads/woosh-rear-hub-kit-xf08c-cassette-freehub.36035/

it should be possible to do if I rearrange the washers and torque washers.

does anyone in here have any experience with this ?

Is your frame steel like the one from your link? Otherwise no.

hmm.. it looks like the frame from my link is made of aluminum as mine is

If your bike frame is aluminum, then spreading the frame to insert a longer shoulder-to-shoulder axle may cause stress fractures (often at the BB shell weld area), which may never fail but could fail suddenly and catastrophically at a moment of high stress (bumps, braking, etc). What happens after that depends on the exact failure and how well you can recover from it and whether there is traffic/etc around you when it happens.

So, while you *can* do it, and nothing bad *might* happen, it *could* break your frame later on without warning, so do it at your own risk.

Another way to mount a motor that's got an axle too wide to fit in the dropouts is to make a pair of torque plates that will actually hold the axle, that bolt to the *outside* faces of the actual dropouts on the frame, placing the axle itself just below or just behind the frame/dropout so it isn't stretching or bending the frame. There is a Torque Arm Picture thread that may help you figure out how create these for your specific frame and motor.
