Maybe we’re getting off topic but my thane build wouldn’t skip as much because the wheels themselves would slide. On pneumies the tires don’t want to slide so then the belts skip more.

This is very true, since switching to gears from belts I have yet to be stranded anywhere due to a mechanical drivetrain failure. Worst thing that happens to me is maybe a flat once in a while. It’s hard to imagine going back to belts, the only reason I can see is maybe some weight saving or some very specific builds that gears can’t accommodate

for me the literal only reason would be all these wheels coming out that won’t mount to my gear drive.
but I plan to get an AT gear drive to aleviate that qualm, so it’s more my issue than an issue with gears or belts.
The green loctite on my BN drives failed once, wasn’t catastrophic either, just disabled that motor and went home. Just like if a belt broke, except it took me a year+ and 1,000+ miles for it to happen once

This is pretty much par for my experience too, but with the flying out Kegel pins.

Well! if the gear are made from POM and it break, i bet you already know the answer why that thing breaking down.

BN drives use hardened steel gears

Not the drive gear, only pinion that got hardened.

Yeah that’s a lot of miles, especially on small tires like we use, the amount of revolutions and vibrations our stuff goes through, it’s incredible that things are problem free for even that long.

Yeah you wouldn’t want both hardened

Hardened steel is brittle than un heat treat steel, you can think what going to happen if hardened steel drive gear going to face with high impact load without rubber coupling to soak that shock. Yike!

Properly designed steel gears are case hardened, not through hardened. (soft core hard surface)
I believe BN gears are case hardened.

The rubber coupling is also to help with reducing wear on the mating surfaces
Mmmmm not relly i can not see any of the heat treatment mark on drive gear, but for the pinion, sure~ it hard
I dont think anything is wrong with belts. Mine last a good 1200 miles and takes less than 30 seconds to swap out. But for pavement and nothing else, is fantastic. Way better than hubs.
Gear drives i would use if i wanted a closed system for exlcusively offroading. Keep out the fine dust and mud that can cake on to belts. Belts are terrible for offroading.
The resistance of the terrain alone with belts puts unnecessary axial force on the motor stem and can snap it. Had it happen to me on a 4wd drive build (grant it, it was an 8mm motor stem and was a build of Dave Derrickson, rest his soul), but it also happened to a buddy’s trampa build that was running belts.
20mm wide belt drives and better tensioners should help with that fwiw

Nothing about gearing ratio…?
