Re: Tubeless Rim's What Brands ? Prices ?

I done a ghetto tubeless job on a 26 inch rim with a 1.5 tyre and i got it to 80psi recommended max and the tyre slipped over the rim and blew clean off in my hand, the rim ended up a few metres from me where I'd chucked it out of reaction to what sounded like a bomb going off so do it outside I was...

Re: Razor e300 ultra. Technical guide

IMG_20190120_235603086.jpg _IMG_000000_000000.jpg Those with a keen eye will have seen the rear wheel is off centre by 5mm so the rear drop out needs to be 1cm wider to get perfect alignment. I'm going to cut the centre bar out of the rear and widen the frame in that area by the 1cm then I'm going ...

Re: Chaos 48v 1600w scooter upgrade / mods log

It's going below the low voltage threshold and the controller knocks off, seems like the lead is dead of get yourself some cheap Lipo if you can look after them or get a generic 18650 pack with bms but be sure it can discharge the amps you need. Lead is not worth replacing it's performance is obsole...

Re: $14.99 72v Sunwin Controller

My controller is knackered now if I hold the ride back it just acts like there's a bad hall but the motor is fine so it's sat in shed for a year nw it's gonna end up down the tip but it served well for the price, I think it's a simple fix properly not burned out but I just don't have the time and ha...

Re: Alternator into BLDC

You need to use a multimeter and link them in pairs if there's no continuity it's not the end of the coil on test, find the 3 linked pairs then connect them start to end and run a wire for each of these phase's to the esc for delta. I'd say run it in wye, there will be more efficiency at lower rpm a...

Re: Alternator into BLDC

Is that the cleaned up coil it look like it's got some age. With an alternator the coils you have are the start and ends of three phases that can be combined at one end for a wye config or joining the end of each phase back to the start of the next and that is then delta connected. The rotor with it...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

I don't think this will be an issue as we can make endless amounts of stationary energy that can be transferred through the grid to manufacture on a global scale Given the problems countries have with blackouts, high power prices and grid stability - I don't think that's true. And much of it depend...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

High embedded carbon energy content of batteries also raises another question beyond atmospheric emission: Can batteries and solar panels make and store enough energy to mine, refine, transport, and manufacture more batteries? Or will our capacity to do these big things slip away as oil leaves us o...

Your seat looks like it's facing the wrong way to me narrow at the rear but it looks comfy and it suits the bike in a position sense.
