BOOM!
Printed a larger controller box and got that fitted on. Got a bunch of the wiring right-sized (made some of the phase extensions way too long) and got it all nicely wrapped up in some sleeving. Replaced the front tube (pinched in on first install, doh!). Just generally buttoned up most stuff and got it out for a test ride.
Touch the throttle and you're at top sped. I did de-rate the front motor a bit due to the less-than-awesome torque arms, which was probably a good call since even taken down to about 80% of the rear's config, it still did a
liiiiitle bit of chatter on take off.
No hill could stop this thing -- the battery hasn't been charged for a while, so it was in the very low voltage range and only holding 20-22mph, but it did that up every hill in this area and there are
some[1] doozies[2].
There are still a few finishing touches to sort out, like fixing up the left-hand-front-brake which is on the right side, just upside down (on the left, I have a brake lever that's actually a hall trigger, basically, which controls progressive regen). For the heck of it, I may toy with de-powering the front motor down to 10A just to see how strong it would be as a single motor. I want to get some heat-shrink wraps around those nylon sleeves to tidy up the ends. I may toy with some field weakening to see if I can eek this into the 35mph range.
