You might only be able to buy the stickiest rubber in certain sizes. So, while one tire\wheel size might have a huge contact patch it might only be available in non-sticky compounds...

Ok good, that would've been my next suggestion, LoL. Not sure what to suggest on your original question. I just charged in bulk @ 72v and checked the packs often....

Quick question, are you sure the BMSs on your packs actually do balancing? I built a pack as you described using hoverboard 36v packs. The BMSs on those packs were only for protection, they didn't balance. So I had to periodically check every pack and balance it if needed...

The app I linked used to show all the individual cells, but its been updating its versions very often lately and seemingly reducing functions with each update. I stopped allowing it to update, so my version is older. So I guess that app is useless now unless you can find an old APK...

Okay, I've got some more info on this BMS. For starters, I almost lost my entire pack due to this BMS! It got cold here and the bike and battery were left out in the garage with about 50v on the 14s battery. After a couple weeks I checked the voltage and the pack had discharged down to 15...

Just fYI 50% of all Kalk models sold are being recalled: https://www.webbikeworld.com/cake-kalk-catches-fire-leads-to-recall-of-over-260-bikes/

I've got the generic 100A BMS that BH sells. I thought I'd start a thread to focus some general knowledge about these units in one place, since BH doesn't offer support or manuals. I've got mine connected to a 14s battery and it's is working fine. For the Bluetooth module, I downloaded the...

If you're still looking into these cells, there's one guy on FB who has built a big pack with them. 26s4p User name is Ean Hubbell. Search for him in the Electric Motorcycle Builds group is this link doesn't work...

Awesome info. Thanks for the update.

Google:. Head tube angle set You can get up to 2 deg of head angle. That should help quite a bit...

Saw this on another forum. The posters were having a hard time finding info on this bike. Does ES have the knowledge? https://www.facebook.com/marketplace/item/1573964803051744/?mibextid=dXMIcH https://www.grassrootsmotorsports.com/forum/motorcycles-and-bicycles/early-trek-ebike/228295/page1/

Really cool build man! Where in PA are you? I'm very interested in the whole VIN aquisition process. Keep us posted on that.

Impressive build!

Do the cracks look like this? If so, I think my motor has always looked like this inside. I feel like it's from the manufacturing process, but I don't really know. But I do know that it hasn't gotten worse over the years & I will regularly push 6kw thru this 1500w motor...

If you don't go with the Zero motor, you could look into Lightning Rods offerings. They have some powerful ipm motors & controller options. https://lightning-rods10.mybigcommerce.com/xxl-motor/
