"Shelley Green Pressure Connections Crimping Isnt as Simple as You Thought" from 2019 Hackaday Superconference Hacking conference

I have nothing original to add to this. If you've ever wanted to know the science behind a crimped connection, well there it is! 21 minutes all content and no filler.

that sales pitch *confused*  thanks for sharing, I guess? technical discussion always welcome.

"Elon said they were building the Roadster II "NOW" back in 2018.  How's that coming?"

Not sure of this comparison? Is there Ducati footage that Elon (Musk? assumed) claims to be the new Roadster II as well? That would also be misleading.

I don't like the word "scam". What is a better way to express that this is not a real product and the marketing is whack?

Renaming topic as such.

"Electric Motorcycles Discord"  o/t but can we get that discord bridged to the Electric Motorcycle chat on Matrix? Who's the discord server owner?

*edit* Found it. Request submitted to the Discord server owner role.

...Just to complicate things a bit more Zero has a copyright on a new model ...

Trademark not copyright; This is not a new Taylor Swift album.

Zero FX and DSR 2022 model year may be the last products of Cypher II parts that are getting phased out. Keep this in mind?

Maybe get a Sur Ron X to hold you over 2-3 years until the next generation Zero product lineup settles out? I might even suggest Sur Ron Storm but those are not common. If you are going with EV moto you should get whatever has the most aftermarket and a healthy DIY repair community. EV moped and motorbikes from any brand will be a lot of fun to ride on trails. Spending 2-3 times more money doesn't really equal more fun on trails at 25mph, it will just be heavier and more cumbersome to transport to get to the trail.

Such clear and useful photos unfortunately with a repair mistake that can lead to fire. Yikes.    12Vdc ? (not equal to) 125Vdc

EMF forums here tend to coalesce on commercially-available vehicles as a starting point. The "endless-sphere" web forums are known as a valuable resource for DIY conversions, and in great depth too.

Some of the secret sauce? Motor controllers! Quite a lot of motor controllers exist, and almost surely the controller you decide on will determine limitations of battery and motor selection, also just plain limitations as the motor controller may depend on computer programming that you are forbidden from modifying or even having knowledge of.

To that end I suggest first determine if the community-supported VESC brand of controllers would work for your application? If yes, do that. There are a wealth of examples for VESC-based powertrain on all manner of vehicles. If no, then consider taking the powertrain from any existing EV that has sufficient quantity of units "in the wild" you would be able to find support and advice about it from enthusiasts.

There are ready-to-go conversion kits from Luna Cycle shop based on the BBSHD e-bike unit. Wrecked Zero motorcycles often have a fully operable powertrain that can be salvaged as the frame cracked or some other disqualifying reason the bike was totaled out ; however you then depend on authorized dealers since there are secret sauce programming codes for the Zero motorcycle powertrain no one but dealers can interact with.

Looking for something complete? Expand your search to include: Sur Ron X, KTM Freeride e-XC, Cake Kalk OR, Sur Ron Storm (delayed to 2022/2023), Alta Motors Redshift MX (out of production / defunct manufacturer).
