Looking at an idler sprocket option. Gonna get a price tomorrow. Might be the simplest option.

You should be able to take care of it in the way the motor mounts. See if you can make it swing out so it's just like putting on an alternator belt.

14t idler sprocket turned up today so i went ahead and turned a piece of 25mm steel round stock to make a mounting. Drilled through 8mm and tapped an m8 hole in the plate to mount. Ran the bottom motor on its own no prob. Then went for series mode  . Ran a bit slower obviously (just 12v) but also fine.
.........get you motor(s) running ........

Sadly no. I've been tied up with work and getting the evbmw through its test. I will be returning to this project soon though as i have ordered new wheel bearings and a magura twist throttle.

Finally got back to a few jobs on the bike after a month and a half of fun getting the car through the test. The magura throttle turned up today but i was disappointed in the way the wire was setup. Got that sorted so next job is to sort out the back end ........

Well I got the back wheel off , cleaned and repainted. Also replaced the wheel bearings , sprocket carrier bearing , sprocket , brake disc and brake shoes. All in the back end of this bike was in bad shape. Cleaned up the swing arm a bit but this is a conversion not a restoration. I had to make a simple tool to push back the caliper piston. Just a piece of 50x10mm flat steel with a 8mm tapped hole for a bolt. worked great.
I've been wrestling with the battery choice ever since i started the project and came to the conclusion that building a lead acid bike would , quite simply , be a waste of time. My first thought had been odyssey pc680 agm to keep the weight down but the range would have been abysmal. Anything bigger would have yielded a two wheel battering ram.
I bit the bullet and purchased some headway cells for testing and have been blown away with the performance. Based on that I made a further purchase of a quantity of 16 off 16ah cells to begin sizing up a pack. Plan is to start off with a 20s2p pack and work up to a 30s4p. That would allow for at least 600amp peak discharge.
