Re: Luna Cycle's "world's safest battery" lacking MSD

I've only ever seen MSDS for individual cells from the cell manufacturer. I cant say I've seen one at the pack level. I would have thought if you know the cells in the pack you can obtain the MSDS for them from the cell manufacturer. Its been a long time since I've bought a pack - I've built my own ...

Re: Who here has/uses a Spoke Tension Meter?

When I started truing and building my own wheels, a number of books and threads recommended pinging the spokes and listen for the note made in the sound to understand their tension. I found this pretty frustrating and not particularly successful despite being in full agreement with the theory, proba...

Re: How many of you really use the wiki?

I find the information on the forum too scattered. The wiki provided some cohesion in some areas, and I remember consulting couple times at some point. I think it is very underutilised and on my eyes that is a fail because I see forum posts in internet era like 'tacit knowledge' and wikis as explic...

Re: Bafang BBSxx - fault finding and fixes

My dolphin pack connect socket did exactly the same thing. I trawled the internet for hours to try and find an exact replacement - no dice. Molex was a close as it would get that was attainable directly I gave up, contacted Em3ev to obtain replacement parts. It was caused by the socket coming loose ...

BBS Brake Cut Off Wiring Question

I've got some brake lever which incorporate a reed switch as a ebrake cut off. They use a two wire reed switch. I want to use them on a BBS01 kit, which has a three wire reed switch female higo connection. Can I use these two wire reed switches instead of the hall sensors? which wires to go which in...

Re: Found/Abondoned Bicycles

Yeah, they call these place bike co -ops - usually non profit, charity type organisations. Definitely worth looking into, for cheap donor bikes for projects. Yep, have picked up a few from places like this, the most recent an urban crusier style bike which still had the Shimano green dollops of grea...

Re: BBSxx on Big Hit donor

Very nice work, the gap at the top creates an EOM vibe to this, really like your framework! 8)

Did you replicate the Bighit's geometry or depart from it?
Would it be possible to see some more of inside the battery area?

I think building my own frame will be on the cards for the next project!

Re: Hi power inverter for Nissan leaf motor. Dyno's 302.3hp p15

..... the rough plan is to put it in an early MR2 like this: 1989-AW11-Toyota-MR2-Supercharged-01.jpg. Light, RWD, simplistic, some compartmentalised space for batteries. Won't have tons of range, but hoping to go fast.. I used to have the n/a version back in the day. Flying wedge! Would be a good ...

Re: 48 Volt Rear Hub Build

Mudhugger guard would be super nice, but its a pretty expensive option. A guard on the front wheel is the most effective way to keep water off the controller. Failing that a guard over the controller is an option. If all else fails, and you are caught out in the rain - pinch a dog poo bag from a dog...

Nice. Is that frame welded or brazed?

I'd be interested to see your hitch arrangements particularly for the longer trailer. I've decided I would quite like to be able to pick up larger stuff without having to burn more dinosaurs but the hitch is continually the design flaw/weak point.
