Building a new Ebike

[snellemin]

So I went back to the 203mm rotors. I'll be changing the front caliper to Marta FR one of these days, which is slightly bigger and uses the same brake pads. I used my poor man machining skills and trimmed up the rear brake caliper by a few millimeters. It fits nicely after some filing and sanding. Now I can clear the rotor with the 5 speed freewheel installed.
