Does the rear suspension squat when you gun it?
Yep, great recycling, huh? I love aluminum. It's hard, cuts like butter, but it's tough to bend... Unfortunately, it's pretty thick and i don't have an extra 1/8" to spare in the frame triangle. I got some weldable steel sheet that is thinner. I've started working w/ it, but I don't like it as much... More on that later.
And no, the suspension doesn't squat when I gun it. It is harder to do wheelies though...
Lotta work done this weekend:
- removed rear derailer wire and lever/brake combo. replaced w/ ebrake lever.
- replaced front mechanical disc brake w/ hydraulic kit
- tried to disconnect front disc lever/shifter combo but couldn't! i want just the shifter (in case i lose battery power, i'll need to be able to pedal w/ front gears). i was eyeing a simple lever on another bike, and started to take the integrated unit apart, wasn't fully committed, and didn't want to remove all the screws and never be able to put it back together...
- tried to fit new rear disc brake on but failed
---> not enough room beside motor for caliper to fit w/o rotor scraping bottom bracket arm(?)
---> would have to carve too much material out of caliper mount (1/4" leaving only 1/8"?) (and not sure how to do that).
---> burley trailer hitch would hit rotor, and don't have time to make a new hitch
---> so no rear brakes yet. back to plan B: going to try to find/buy V-Brake posts that fit the GT and use the minimal regen I've got now and go slower...
- spent A LOT of time trying to install/program my 846 infineon controller. took 5 days to get the driver working. and now i get runtime error every time i try to flash it... more on that later.
- started building new battery case w/ weldable sheet metal
- carved new torque arm out of 1/4" steel bar. i'm leaving it long until i figure out what else i might want to attach to it, if anything. behind it there's one washer on the axle and two washers behind the bolt, so that it's perfectly square to the axle. that bolt goes through the bike disc brake mount hole and into the disc brake mount itself. i used that piece because it's sturdy, has deeper threads than ordinary bolt, acts like a washer, and is also bolted to top mounting hole too, doubling strength.
