I have searched but I couldnt findeth....

I need to change the drive chain, and I am wondering about the specs. This is for a Ribelle and an SS9 (but they both use the same chain as far as I know).

It is a Regina 525 o-ring chain, but how many links ?

Hi everyone

I just joined the forum today after checking out some of the other posts.

I started building an EV conversion recently using a 1981 KZ440 LTD cafe racer as a donor and have made some decent progress over the last few weeks. The drive system is now together and on the bench and I’m about to start the 12v wiring and the battery box fabrication. Just wanted to share what I’ve done so far as I’ve gone through a bit of pain in some areas and it may help other builders, plus I’ll have more questions so hoping to tap into some knowledge.

Overview for the conversion:
-1981 kz440 ltd with ktm duke 390 front end
-Custom adapted duke 390 brakes
-17” 8kw QS hub motor driven by a Kelly Controller
-24s NMC lipo pack @ 7.4kWh
-Thunderstruck tsm2500 charger with dilithium MCU, BMS and SOC meter
-Vicor 400W switch mode dc-dc converter
-8Ah antigravity 12v battery
-Motogadget mo.unit blue
-Motogadget motoscope pro

EST weight at ~140kg





I also put some videos together for the build if anyone is interested in checking them out. I ended up doing something a bit different with the drivetrain power so it may be of interest to some. The videos are a bit cringy as it’s my first attempt at anything like this so excuse the bad acting and terrible voiceover

Sorry man. That sucks. I've known owners with over 100,000 miles on their original packs. I've also seen what you're going through. Generally, unless someone abuses the pack, I would say in my experience the battery packs are fairly well-built and reliable. The vast majority of owners with functioning bikes don't come to forums like these and say, "hey just checking in everything is still awesome". And yeah there was a 5 year warranty on the pack, but that was 9 years ago. If this was me I'd just start casually looking out for used or crashed bikes that might have salvageable packs. Good luck.

Fantastic EV world….
After 20000km you can put your vehicle to the garbage unless you spend the value of the used bike in new battery….
For me : bought the bike 7000€ rode it for 13000km
Have to spend 7000€ more for 2x3.6 kWh new power packs….
Real cost 50 cents/km
Which compared to gas is 25litres/100km which is a v8 consumption !!!!!
And not even sure to sell the bike 7000€ with new batteries….

I didn’t have luck some bike for sale here in Europe have 50-70000km without too much issues…
I hope that zero will finally roll a program for people like me …
And keep those bikes alive…

The EU version of this lift is called Bike Tower...?

Useful for the dealer maybe, if it requires you to visit your dealer to have the updates installed. That gives them some action and while your bike is being updated (or you are waiting for that to happen) the dealer gets to put the screws to you to buy a new and even more updated Zero.   

I assume only the first update needs to be done at the dealer and after that they are done OTA.


But yeah, I also think the main purpose of these updates is so the dealer can make a little money on maintenance even on EVs.   But I will probably have them do it when/if it's convenient for me.


I have both 2017 Zeros here in Auburn. The first step will be getting them both back to Reno, since that house is close to the Reno Zero dealer (Eurocycles).

As I heard it (from Transport Evolved) he told the head of the supercharger unit to lay some people off and they refused so he fired the whole department as an example.

You are comparing him to Steve Jobs, a man who famously terrorized his employees, abandoned his family, took credit for the work of others, painted himself as a genius, and died from a very treatable form of cancer that he thought he could cure by changing his diet. Interesting.

So to fuck over one man that justifies shitting on 500 regular people? I'm sure there are other ways he could have gone about it, with the money and resources that he has, that didn't negatively effect his own employees. Shit he could have given them all $100k to make up for it and it would have been a water molecule in a bucket to him.

Also you saying they just shouldn't work for him. What you don't realise is those people didn't choose that job to work for Elon, just like people who work at Apply aren't doing so so that they can work for Cook, people don't work at Walmart to work for Doug McMillon, etc. They go there to work for the company. And it is not Elon's company, he's just part of the board of directors and they're just letting him run riot, because he's the major stakeholder I guess.

From what I have been hearing, this isn't the first time the man has fired people in this sort of manner.  Steve Jobs did this a lot as well.
So, with that in mind, don't work for the man then.  Really simple solution.  He can't get good employees, the problem corrects itself.  If it is a legit problem to begin with.

Even if it is a political gotya at Newscum, good for him !!!  F that little weasel, how many people has HE shitted on with his stunts.  Yes the little people suffer in the short term but Elon has an entire company full of people he's looking after, as well as himself of course.  If elon was smart he'd move every part of his company out of that craphole state and let it continue it's rot into oblivion.  Many other states would welcome his company that are much more friendlier to business.  Just the tax savings alone would probably pay the salaries of all those people that got fired.  That's another way to look at it as well.  Elections have consequences, maybe when the people finally start feeling the pain of their poor choices, they'll see the light.   Somehow I doubt it.  As long as they have their weed / wifi / and free shit, all is good.

So, lets see how long it takes for his entire network of chargers to finally die since nobody is repairing them anymore.
