Re: I need to replace the BMS on my bike but I don't know what the wires are for. What are B-, B+, P-, P+, and C- for?

Some BMS are designed to just control the charge, and one power wire just goes straight to the controller. Others are designed to limit and monitor with the battery is in use, which looks like yours is, that's why it has battery positive and negative spots.

Re: New build: Gory Fisher hardtail 750w 36v rear hub -HELP!!

You only need the tool for removal, so if you order a new freewheel, you can just screw it on by hand without a tool, and pedaling will tighten it fully. Be ready to readjust your derailleur though, as it might not like up exactly where the old one was, leading to the gears skipping.

Re: New build: Gory Fisher hardtail 750w 36v rear hub -HELP!!

Freewheel tool.. this is the standard Shimano one, but other brands need their own special tool. Not to be confused with cassette lock ring tool (second picture), which has a different spline pattern. 81oaKk-YJzL._AC_SL1500_.jpg 719H2pTfm1L._AC_SX425_.jpg This is how you'll prob need to finish getti...

Re: New build: Gory Fisher hardtail 750w 36v rear hub -HELP!!

Freewheels aren't meant to disassemble... Just get a new one instead of messing with the old one. You unscrewed the lockring holding it together, it takes a special tool that fits the splines inside to remove properly. The extra connector is probably for PAS hookup. The spark is normal, it's the cap...

Re: Flaky throttle issues

That's actually one thing I almost suggested but checking connections is usually the problem....

Re: Anderson plug irritation

Maybe using the wrong insert for the power levels? The 45 amp ones are noticably thicker. I've had to rebend the tip down on a few after pulling them out of the housing, so they would catch on the spring better. They really don't like it when the wires are trying to twist the contacts in the housing...

Re: New Barnyard Find (Ohm/BionX)

Bionx used that weird 26v charger, then there's a voltage booster in the battery itself. It should be safe to plug in the charger. If it doesn't come on, the system might be too low for the charger to want to start... The factory guys talked me thru getting one going by pedaling the bike with the wh...

Fyi, careful testing...

Do you mean a missing component those should be plugged into? They look like the plugs for a low power controller, but there's so many different generic versions of what you have that's it's guesswork about your specific one, esp without more pictures.

But aside from the prettiness, it still shipped with the plastic of the gear shift housing so shrunk back from wire layer that the shifting was impossible to index because of the mushy end, which of course is terrible on crank drive.

Maybe stolen in the freight. Normally it is delivered fully assembled and tested at a Specialized dealer. And, people who are buying those expansive ebikes usually know what they are buying.

Re: Random buddy bike... Check out the prismatic paint!

I've seen other bikes with prismatic paint (and cars, and a building in LA, and whatnot) and it was hard to capture in stills, but the illusion of depth it had as it shifted, on the curvy contours of the carbon was really eye-catching.
