I have been looking for a modern ( 8 years old or newer ) Full Suspension MTB Frame/Bike and what I am finding is that most of them have the newer style 12x 143 through axle rear frame.
Tried for several months now to find a slotted / drop out frame but not one yet that would work good enough for a rear hub motor for various reasons .
( remember that both the 12 mm and 14 mm axles on a hub motor have 10mm flats to slide up into the usual drop out )
I have been thinking about having a machine shop machine some nuts that are kind of like what is used in Furniture , something like this ... https://www.ebay.com/itm/M6-M8-M10-stainless-steel-allen-flat-nuts-hex-nut-round-head-sleeve-furniture-/222641344318
It would have to have a way for the axle to stop spinning so perhaps drilling a hole in the axle on the non wire side ?
or
How would you do it ?
I have pretty much guessed that the non wire side , most always the derailleur side , would have to be cut down so as to be able to angle the hub motor up into one side of the frame then push the hub to that side more in order for the other side to line up with the inside of the frame, then use some slotted washers on the inside of the frame
Would it work to make a spacer or two one for each side on the usual 135 mm on the hub motor axle , the spacer having a way to bolt it to something on the frame, like a torque arm , just on the inside ?
Your thoughts ? Diagram ?
