I am looking for a friction drive kit working on the wet.
"Sand paper" on the motor is creating tire wear.
Rubber on the motor  seems to be a good solution.
There is such a kit on Aliexpress for $278 ! Does somebody already tried this kit ?

+30$ shipping for me, seems like a skateboard hub motor, there's a few different versions.
At this price I'd considered fechter' and tsdz2
 
This looks like a great bit of kit....surely someone on here must have bought one and can post a small review up?
 
Qiroll sells "stickers" that are stuck on the engine

My first one was torn after 122 km
My second one went away after 140 km

It happened in slopes (5 %) : the engine is warm and glue melts

However I mounted it on a trike with Schwalbe trickers rather flat but 20 " wheels ...

It's a weak point.

I am hesitating to buy a second engine to divide friction's constraint ; I have already 2 batteries
In fact it's to play as my 2 other systems, Q100 and TSDZ work fine
