Don, have you ever had any problems with the votol em260? Mine (E&C kit) is cutting out at full throttle in all power modes. Once I come to a full stop it will go again. I sent it back to E&C and they reflashed their tune but that didn’t fix it. It’s definitely the controller, my buddy let me...

I use a cycle analyst with a remote shunt. https://ebikes.ca/bundle-ca-hc.html It’s made for diy e-bikes but it’s got a ton of great features applicable for e motos. I just sized the shunt for ~500A and made the adjustments in the cycle analyst. Works great. Miles, speed, ah, wh/mi, pack...

No races, just a trail riding machine and banging bars with buddies. QS138 kit from E&C works great. Pack is five 4s 20ah Turnigy LIPO packs in series with a Daly BMS for charging and cell monitoring. I get about ~10 miles out of this setup (140Wh/mi). Currently building a custom pack in a...

There is some good info on this thread: Post in thread 'Battery Build' Battery Build https://www.aliexpress.us/item/3256805881158602.html This is what I use DALY Smart BMS Li-ion 20S 72V 40A https://a.co/d/2YiRZVQ

Spare parts and rear handbrake kits are now available from Stark. I decided to give it a try on my 2006 CRF250R conversion. I bought the master cylinder and brake line to pair with the CRF Nissin caliper. Parts showed up in less than a week. Master cylinder is manufactured by Formula Brake...

I only needed a couple of each unique shape so it was per part. I didn't get it quoted in higher quantities but I'd assume the more you order the lower the piece price.

For the next guy/gal stumbling across this thread; Based on the info/photos provided, the vendor might be WELLGO on Alibaba. They took my 3D CAD files and gave me a quote on 5 different designs. Roughly 8 bucks a piece for 1mm copper with a three week lead time.

Wow, would you be willing to share the vendor and rough cost? These look quality!

Hey Don, you mentioned cooling for the controller at high amperage a couple of times. Could you elaborate on some solutions you've found or heard of? I've got a kit coming from ElectroandCompany with the EM260 for a CRF250R.
