Hello all, I'm just jumping in with my first project converting a Brodie Bandit hardtail using a 26" rear hub eZee kit from ebikes(Grin Technologies).
I didn't get very far before I ran into two problems:
1) The brake rotor doesn't seem to align with the existing caliper. I'm not too worried about this as I should be able to make some adjustments to the caliper mounts.
2) The new axle diameter is larger than the rear dropouts on the bike. I don't have anything to measure with but from what I can tell it looks like the dropouts are 10mm and the axle diameter is 14mm. So I have a few questions:
a) it's not clear to me whether the axle should have flattened sides or not. It does on the gears/threaded side but not on the disk brake side. Is that normal? I am assuming it is.
b) Should I file only the dropouts or both the dropouts and create flat sides on the axle itself?
c) is it 'safe' to file the dropouts 2 more mm on each side? It is a steel frame so I assume it should be ok.
Thank you in advance. pix attached.
