This is what happens when everyone rides ebikes instead of driving cars; assassins have to adapt from the tried and true car bomb :oops:

It's a stark reminder why we shouldn't go messing with the internal wiring of our eBikes... besides voiding our warranty, this is NOT do-it-yourself territory.

In both video examples above, they appear to be those high-powered eBikes (1000-8000+watts with suitcase sized batteries) but I guess some are in kit form and have to be assembled by the customer when it arrives - simply by following assembly instructions. I mean, how many DIY people can properly assemble an IKEA flat-pack piece of furniture with zero error - all screws accounted for, no stripped threads, and no misidentified panels?

I'm sure many of these bikes have been put together trouble-free, but I've also seen videos where well-meaning enthusiasts stuffed foam or fibrous packing material around the BMS and battery clusters to make it shock proof presumably. These things get really hot and need air circulation if any, but most certainly not inappropriate thermal encasement.

I still subscribe to the idea that especially because cyclists are inherent mechanical tinkerers, cyclists should really leave the entire electrical system alone - unless qualified in this specialist field. I've seen first hand what's involved when a team of electrical engineers develop a BMS for a specific battery and motor combination. They were constantly measuring and testing various output, loading, heat and cooling rates... sheesh!

I think the second video is a brand new bike on it's first start up as soon as the power was switched on. ?

Not disagreeing at all.

Just found this video. This dude suggests over charging coupled with physical damage (from a fall). I imagine physical damage could easily happen with poorly made aluminium casing (sharp edges, rivets etc). It sounds like he also limits the highest and lowest voltage output of his battery bank via the bms. Still no vents though - I'd go the extra distance :)

The good thing I got out of this, is that I'm going to get a fire extinguisher for the garage :oops:; geez why haven't I done this years ago :unsure:. Always had one in the kitchen.

Eric: "My weird wife"
Yuka: "It's you" :ROFLMAO:

Often I prefer to see how people who are still learning (still way above me) approach things. It is a bit closer to reality for me. This woman often amazes me. Her partner is precise and knowledgeable, but wary. Yuka is not so wary and not so precise or knowledgeable :ROFLMAO:, but she just does stuff

It might be a coincidence, but I did some live drops today. I'd been sessioning drops off concrete slab onto a nice grassy hill for practice. Today I rode over a couple of drops that I normally ride around - and did some sessioning on those. It's a definite step up for me, and yes I did watch Yuka's video this morning :ROFLMAO:
