Rear Hub motor and axle size

[barbe]

soundwave, thanks for the info! I didn't know this frame was in 29 too, bc kirbebike sells only 27,5

 

[barbe]

but, like you wrote, where can I buy just one!

 

[soundwave]

some frames a 29er will fit and some it wont on the rear but email andy and see if his frame will take the wheel size you want or not imo he is your best bet if you want one of those.

 

[barbe]

sjpt! you make me think of "hell on wheels"!

 

[barbe]

soundwave, I suppose andy has bought 50 27,5....and no 29 !
still not easy to sell 50 frames...

 

[barbe]

and andy didn't answer one email from me weeks ago....
but imo you're right!
so, as for yet, I don't buy anything....

 

[soundwave]

it might fit or it wont but there are frames out there its just finding one and imo andy would have more of a idea where to source one from.

 

[barbe]

thanks you all, you helped me!

I have a decathlon aluminium frame bike which I want to convert using a yose power rear hub kit which requires a 10mm axle dropout on the frame.

What shall I do? Is filing safe? I also cannot find any alternate donor bikes with 10mm dropouts..

The Yose kits have a 12mm axle with 10mm flats milled on them. That will fit in a standard bike frame with normal Q/R rear wheel. Very occasionally, you have to file off a bit of paint to get the axle in. The biggest problem is that sometimes they don't go in deep enough, so you have to file the drop-out deeper, which also helps re-centralise the disc if you have a disc brake. Another solution if it's not too bad is to use a torque arm, but only do that if the whole of the axle is in the drop-out, and it's just the torque washer which won't go in.

Q/R front forks normally have 9.5mm drop-outs, so they need filing. I wouldn't advise using a front motor for other reasons.

What do you think is special about your frame why 10mm won't fit?

Decathlon bike dropouts are designed for 9mm axles. That’s why it’s not fitting (I have the kit and I tried). Maybe I didn’t test properly (as I’m new to this)..
