Unless you were approaching an intersection while going downhill, then it would be a 50/50 bet for me lol
Also I’ve yet to see any evidence that a broken plastic gear couldn’t lock up a drive

I had a hardened steel mod 1 pinion that lost half a teeth. Interestingly didn’t even notice it until I disassembled the drive for service probably much later. There were some weird sounds coming from the drive occasionally but kept running it being lazy to service it
Wasn’t jumping with it, but I was racing it. Pushing 200A into the poor reacher at 21S so it definitely took some abuse. Went to mod 1.5 since then.
I don’t doubt that it could, but anecdotally i’ve broken 3 or 4 plastic gears without major incident. I’ve had 1 steel gear related failure with major incident.
EDIT: in fairness I did have a motor failure with my jump drives that ended without major incident, but I did have to walk my board several kms out of the bush
But seriously, none of this is an issue with belts
Belts have their own issues though, like completely sucking ass in the snow.
Everything has pros and cons, it seems.
Without snow though, belts are pretty good…
Small pebbles do eat away at belts pretty quickly. I cannot really avoid that kind of terrain around where I live.
I prefer to have a new-ish belt and an old-ish belt on a two wheel drive. I try not to replace both simultaneously and if I do have to, I look for a used one for one side. That has been working really well for me.
They suck in the mud too. Also on sustained steep inclines, shredded the teeth off of countless belts. It would consistently happen when having to slow down then gun it in a steep spot. That was on the older Trampa pro belt drive. Maybe the wider ones are better now.
They’re perfect if your setup is perfect and conditions are perfect and and and and
I see steel gear drives lockups the way I see plane crashes.
Usually due to poor maintenance and very very very rare.
Why?
So as they both age, if one fails or otherwise just needs replacing, it’s unlikely the other one is anywhere near failure points. Putting a new one that side just repeats the cycle. So I’m less likely to get stranded anywhere, or otherwise be in a situation where I’m riding with two very-poor condition ones.
Even though I usually have extra belts also, but I really don’t like working on a vehicle in the field, ever. I’d rather finish the journey with a single motor, and also I don’t like being late for work.
And that my friends.
is everything you need to know about NewBee.
ah! he must Bee New 'round here…
A plastic gear doesn’t actually lock the wheels when the teeth break off. It starts to slow down, but the force during the ride is too strong for it to seize up completely—at least from my extensive experience.
Hivis has an m1at drive lock up and he broke his leg… failure moves to the weakest link and if the drive is solid steel… you become the weakest link
Was the root cause found? What specific piece broke in what manner?
Not my story, just drug him out of the road. Don’t know if he’s been up for figuring it out yet. Just another anecdote but you were asking for anecdotes. Ive had pom/steel hybrid break and the steel just eats up the pom and free spins… more anecdotes.
Once when i was full throttle and hit an un marked un filled street cut for construction - sucked but just had to limp home on one drive. Second time was a wreck so not applicable but failed similarly
What was the root cause? Broken gear teeth? Which piece of the machine malfunctioned first and in what manner, for each occurance?
Hivis steel gear failure: Don’t know, but the motor was locked solid, the gears wouldn’t move, tire was locked solid. If there was a weak link to break MAYBE it could have been a better outcome. Maybe it COULD have failed in a less catastrophic way. But even knowing the exact failure mode wouldn’t change the situation much - as there wasn’t any give in the system. Any of the components gets locked up and the entire drive train comes to a halt.
Not a reliable data point but there just aren’t any good data points in total. My FEELING is that i want my drives to be a point of failure that is not so unreliable as to break all the time in normal use but also not so strong as to make any failure catastrophic because the failure is going to cause the wheel to lock up. Belts just slip too much on the hills i ride. I want the gears so even though they can be run without attention for thousands of miles - i break them down and check on em and about every 6-800 miles. Been working so far ¯_(ツ)_/¯
Edit: I also think i bench my boards more than average, no trust
