Re: BionX Motor Issue

does the motor/wheel seem to have higher resistance to pedalling even with the system powered off? if so, it's possible there are blown fets in teh controller (which is probably inside the motor)..

Re: There was a fire at my house today while I was not home.

No leaks yet on the pipe fix. :) My brain kept working on the problem anyway (like it usually does) and realized that if I have further problems with the crimped/soldered "fix", I could desolder that entire branch, taking it's "T" out of the pipe along with the extension from that T to the next one ...

Re: Manitou SX TPC fork Disc Brake adapter

The spacing on the mounts are not the standard spacing you have on forks now. I did some digging, and it seems they are 68mm. Would that cause any problems for me ? If the spacing is not the same between the posts on your fork and the holes in teh adapter, it wont' work. So you'd need to measure th...

Re: A2B problem

Could be blown FETs in the controller. If your controller is external to the wheel, then disconnecting that from the motor would let the wheel roll normally. At least some of the A2B bikes use the Ultramotor, which has a built-in controller. If yours is one of those, then disconnecting the motor con...

Re: BMS not balancing...

What is that BMS's balance point set to? What voltage does it turn on the balancers at? What voltage does it turn off the balancers at? You can measure this if you leave a voltmeter connected to a cell and note what it reads when the BMS lights come on and go off. Test each cell group as it happens ...

Once the tip/cap is off, just tap it on a surface...

Re: looking for recommendations for BMS upgrade

Unless you pack the cells like they already are, as a "brick", you can't apply even compression across their faces (without building something with individual cell compression plates and edge-mounting hardware). Without even compression, they're going to swell/unswell, even if it's just minutely (an...

Re: Strange problem with my bike. Controller?

Controller probably has blown FETs, shorted internally. http://ebikes.ca has a Learn page with Troubleshooting info on how to test for those.

The wheel rolling fine without ocntroller means wheel is fine, and so is wiring up to the point it connects to controller.

You can look up "sprotor" whcih is a brake rotor that is also a sprocket; that's one option. Might have to custom-make it if the size you need isn't available anywhere.
