Electrified Downhill bike

[zeropointbug]

Okay, I see that you mentioned torque bars in the previous post...

The dropouts are aluminum, everything on the bike frame is either alum. or magnesium. I can get a torque arm made for the disc brake side (we aren't using the disc brake anymore, caliper doesn't fit between rotor and motor), but for the gear cassette side I am not sure. Will one good torque arm suffice with 48v/40A NC kit?

I just got done doing a no load test with 12 A123 cells (26650's) for 36V, no load speed was exactly 50kph or 31mph, so when loaded with 48V hopefully it will hit that speed on flat terrain.

That is what I am thinking for the battery connection plate, although I will add ridges between each terminal to prevent small metallic objects being welded to the tabs, or at least reduce accidents from occurring.
