I hope your batteries never have a catastrophic failure cause you will end up singing castrato soprano in Italian operas. Ouch! Actually it looks pretty cool despite the unfortunate placement of the batteries(at least the batteries are not Li-ion or you would be doomed!)5chn3ll wrote: ↑Wed Nov 07, 2018 9:49 am Aiight, the finished goods. I'm still shopping for a low-profile front caliper, but everything else is dialed in. Full charge range test will come as soon as the front brakes are sorted out...
The bar ends allow me to flip the bike upside down and work on it without tearing up the brakes, shifter, throttle, etc. - and will hopefully absorb any whacks the handlebars take in the event of careless cycling...
This shot shows the SLA battery pack (20 pounds, give or take) hanging from the top tube. The chunky red and black wires were the original connectors for the rack-mount UPS module that "donated" the batteries; better quick-connectors are coming eventually to make battery charging and swapping easier.

With the torque arm installed, no more shenanigans with the lowers. Even so, I really like to take it easy on the throttle. I may replace the thumb throttle with something a little more precise...while it's fun to blast down the street wide-open, pedal assist at low speed is a little touchy.

Charge-o-meter, throttle, and comically large brake levers with integrated kill switches...
