Did 5 Sherman’s really die at overheat hill? Yikes!

Ok fess up... How many EUCs got broken this time?

The bonus day (day 8) at Overheat Hill was a wheel-pocalypse! One wheel went off a cliff, and 6 other wheels were incapacitated (4 Shermans, a 16x and a Nikola). The crazy part is that we never even made it to Overheat Hill itself!

Yikes. Lots of walking involved... at least it was downhill?

6 wheels died before overheat hill? Too much gear? Alternative path? Sponsors must be happy!

Actually the reason was something none of us expected!

Ahem ahem...

The morning started out with a constant falling mist/drizzle. The ride was going to be cancelled for fear of the trails being un-rideable but it let up just enough that we decided to go ahead with it. It started out fine and we were able to ride the early trails and the warmup to Overheat Hill with basically no issues. The sun peeked out slightly at one point and we thought the weather was going to take a turn for the better, however when we left the warm-up and headed for the actual Overheat Hill, we had to traverse some awesome cliffside trails, and that's when the rain started to actually come down. Not too hard, not like a downpour, but hard enough that it was actually "rain" and not just drizzle.

Anyway, it was at this point that one of our veteran riders just happened to go into a turn where the ground was significantly softer than expected. He slipped and the wheel took a tumble down into a ravine! He took off after it and a group of riders stayed behind to guide him back up as he and another guy dragged his wheel back up the side of the mountain for like 200 feet! 

While that was going on, another group of us pressed on to the next safe point on the trail to avoid causing a huge traffic jam. At this point however, the rain had turned the top layer of fine, powdery dirt on this particular section of trail into a super-sticky mud that glued itself to all of the knobby offroad tires. The first Sherman to arrive at the safe point picked up so much mud that its wheel jammed and seized inside the wheel-well. It happened so suddenly that when the rider tried to lean forward to keep from falling the control board blew! The next Sherman to arrive was still running, but when the rider tried to move up to the top of a nearby slope it also seized about halfway up. Next was a Kingsong 16x and a Nikola, followed by 2 more Shermans! 

All of the riders whose wheels had seized had to start dragging them out of the park... Dragging, not rolling! I'm sure that any of you who own one of the heavier wheels can imagine what they must have been thinking as they realized what the rest of their afternoon was going to be like!

Anyway, a couple of us with wheels that hadn't been affected by the mud managed to transport a few of the incapacitated wheels down the mountain and out of the park without slipping and falling to our doom, so the day mostly ended up being great fun all around despite everything that happened! 

One of the funniest things in my opinion is that a couple of the riders with street tires were worried in the beginning about traction in the possible mud, but by the end of the ride they were some of the only people who didn't need to worry about the safety of their wheels because the mud wasn't sticking to them!

V1 or V2?

To my knowledge, that would make no difference (as not particularly proud destroyer of Sherman board myself)

[Tawpie]

What I read had 4 die before they got to overheat hill itself. And a 16X and a Nik. Kinda spendy afternoon overall.

Sounds disrespectful toward gear and ressources to go on at such a rate. Rich frat bros?

There is a young man on YouTube that buys trucks that I would love to have, ( fully restored 4x4 1978 Ford, almost new Chevy trucks) and absolutely destroys them for YouTube views. Nothing left to salvage. It makes me sick. I can’t watch it.

Let’s hope Uber was available, or there was a sag wagon.

let’s hope it was just control boards for everyone.

There was a simple modification to change the fuse connected to the battery from 50amps to 30. Ewheels sent out fuses to those who requested them.  I’m curious how many made this change and if it would have made a difference?

No difference: the amount of current sufficient to destroy some components and have the battery wires start to desolder (mine) or burn-up entirely (a friend) a Sherman mainboard is lower than what what trips the 2x 30A fuses.

It would be great to find out the grade, temp, speed and distance on that hill that wiped out the Sherm’s. Maybe someone can share their data.

Agree! I'm interested in any related wheel log.

Purpose: create an algorithm for app alarms  tuned for Sherman.

Thanks for surviving to tell us this epic story! 

Do you think that all the wheel died because their wheel seized? I'm surprised about the 16X especially since no (good) knobby is supposed to be available in this size.

As far as I can tell, yes, all of the wheels were incapacitated in some way due to them seizing from mud. Luckily, I've heard that at least one of the Shermans we thought blew a board actually survived the ordeal and will still turn on now that the owner has cleared most of the mud from the wheel well! I know for a fact this is not the case for all of them though... I've seen pictures of the internal carnage...

I just wrote E-Wheels.

Just speaking based on my own assumptions here, but I'm going to say that no, the fuse change wouldn't have helped in this case. As far as I can tell, the fuses are there to keep a potential short from damaging the battery packs and/or causing a fire. They're not going to protect the board from blowing itself as it's perfectly possible for 30+30=60 amps to blow a board if it's put in a bad situation, such as the wheel seizing and all of the current getting dumped into a single motor phase for a solid couple seconds.

Never forget.

I'm surprised this didn't happen much before.

We had a similar story where my V11 also got totally stuck from the mud with a knobby on, I realized it in time and turned it off to avoid blowing anything. Had to carry it for a few kilometers, where I could finally get rid of the mud using a well.
