In the first pic of the lifted wirebond. was this after you tried some sort of repair? It looks like the white plastic ring insulator is discolored there and that part of the metal rim on the battery is eroded back or ablated. I think there must be heat in the wirebond process but I don't see...

First crude experimentation. I'm getting full voltage from the wire stuck to the cell. There is about 1 ohm resistance, though

Trip report, por favor. hope you had a good time. I'll be there in a month working the trails from denver to moab and back. everybody else has fire bikes but I dang sure aint leaving my Alta home this time. Any locals want to do some electric offroad activities? One blind spot I have is...

Can you look at your ride logs and tell how fast your rear wheel is spinning when you land a huge jump? Say your ground speed is 30mph and the wheel is going 70mph when you touch down. instantaneous deceleration? I wonder if a ktm cush drive hub would help a shaft to survive, flatten the...

It looks like it had a fissure forming around the circumference of the shaft given the look of the oil contamination. Finally weakened to the point of the remaining material shearing off "cleanly". Point is, maybe it was visibly cracked for a while and that area might need watching as our...

How can it have a bigger battery compared to ours and weigh less?

I'm game. whats the usual riding scenario as far as HQ and charging etc. Ive been twice, burma rd, i think but never on an electric

It looks pretty tidy to me. Mechanical water pump on the right cover? I wonder what the shutdown situation was.....

I see three flaws here. I wouldnt bother with the Boulder stop. I would avoid the 1-25 routes shown, plenty of back roads from Denver to Pikes peak to sand dunes. Lastly, Don't even consider not bringing the ALta. Fit it anywhere you possible can in your rig. You can ride it while your...

I'd buy the skidplate if its still available

incorporate a tunnel/huge culvert under the tabletop?

The ones in new zealand might come with real seats if they are ever produced https://www.ubcobikes.com/frx1-trail-bike/

Wouldnt a quick visual inspection be the next step? It's the bottom module so maybe this is another corrosion victim. You guys used to be on the East coast where there's water water everywhere.

I see no good reason for you not to get the cake bike. I'll be happy to read reports of how it works in your situation as there is not that much info out there as to how rugged it is when ridden enthusiastically. Horses for courses, it might be perfect under the powerlines.

I'm going to order some of the epoxies out of curiosity. Also, from the thread Ray linked to is this spot-welding-fuse-wire video

I can help with the multitool part of it

What inside a controller can turn into a breif fireball? BAC BAC looks like a plastic case but so is sevcon, mobipus and kelly. might a metal case have controlled this fire better?

I'll buy your inverter depending on the details. post it up or send me a message(y)

Here is the actual comatose machine. It was born a r&d machine and remains so. The crude reverse engineering I'm doing has turned into a hobby now and I'm absorbing alot of info. One of the avenues forward is to bypass the alta secret formula and settle for something less. To that end I'm...
