How to apply a torque arm on this decathlon 520 mtb?

[Coop]

I bought a decathlon 520 touring mtb https://www.decathlon.be/nl/p/tou...-6HWso18cZM6HdylbEaAldAEALw_wcB&gclsrc=aw.ds

I also ordered a 2000watt ebike hub kit, I will receive it in 2 weeks or so.
I need a torque arm, but how would I fit it?
I never seen how they do it on these frames, is it even possible?


It lays 15mm deeper then the arms were I want to connect them to, is it even possible?

I just realized I don't have much space to fit a bolt in it.
Does anyone know what the diameter of the nut is?

Guess I'm returning my bike, I can't screw the needed nut in that tiny space

Can't say without knowing which hubmotor it is. Mine are similar to simple auto wheel lugnut bolts. In fact, I connected a trailer to the axle using one from my old Volvo.

That is one of the problems with a frou-frou frame. Sometimes the "fancy" design features are counterproductive for us.

Thanx btw.

Put a torque arm on the inside of the frame instead of the spacer washers

All decathlon mtb bikes have this frame, I always thought decathlon bikes were a good choice for hub conversion kits.

I don't think there's enough room for a nut, or a wrench to tighten it. Usually you'd want to slightly deepen the dropout to fit the larger diameter axle correctly, but then there would be even less room.

I could dremel and take away some aluminum, but it would weaken that critical point.

Return it is the best solution, and buy me an other bike...
