The Apaches 4.5 and the Jumbo Jims 4.8 had a rubbing chain.
But I replaced the rear 4.8 JJ with a 4.4 JJ to avoid chain rub. That worked.
Thats only with the 100mm rims.
I'm sure that the problem won't occur on 80mm rims.
Tried some other tires today.
27.5x4.5 45NRTH Vanhelga 80mm rims
Great tire, feels much more like a mountainbike. Very agile!
26x4.8 Jumbo Jim (26X4.4 rear - no chain rub)
26x4.5 Apache Slicks 100mm - look cool but even with 30psi they feel strange.
Those Apaches look good but they ride like s**t.
Put at least 25-30psi in them or you will have extreme self-steer
They are also very wide (4.9 on a 100mm rim) Can't shift in to the lowest gear anymore.
I squeezed 14S5P in the original housing. It is a tight fit and I had to move the on/off button to a different location.
No room for the BMS so I placed the BMS on top of the case.
In the frame a hole was made for the BMS.
Saw a guy that put 70 x 21700 in the frame but that takes a bit more...
