Lotsa new stuff.
New (NEW!) wheels. I replaced the rear QR axle with a solid axle.
Disc brakes.
Metal idler and derailleur pulley sprockets with bearings
New throttle and shorter cable
New rear rack
A whole pile of USB lights chucked.
A new light systen with onboard 12V lithium battery. Triple brake lights on rear. 15W RoadShock flood on front. Mini bullet lights with lenses I added to make 360° visible.
Pictures after a battery test running hazard flashers for 3 hours,,dropped 0.2 volts off full 12.6V charge. A voltage display is on top of the black box, charge port and power switch on side, fused inside.
The battery is 3s2p 5800mah. I can charge it with a solar panel but it appears I'll have plenty of range for normal riding using no lights except turn signals and brakes.
Ready To Roll.
