Having just spent a couple of days there I'm convinced the only way to improve the every day life of people in London is to rub it out and draw it again. Sent from my HTC 10 using Tapatalk

Thanks for for the pics. Having never taken one apart I'd sort of concluded they had some kind of barb/ratchet inside. This makes a bit more sense now. Great post! Sent from my HTC 10 using Tapatalk

That's what eBay is for. Sent from my HTC 10 using Tapatalk

I'm pretty sure Jimmy could do it. With these new 3.5ah Panasonic cells you'd only need to get 21 cells in there for a 3s7p, giving 25v 10.5ah. Sent from my HTC 10 using Tapatalk

Why not re-cell it with modern 18650's? Sent from my HTC 10 using Tapatalk

You may be able to DIY, but you'll need a spot welder. I'm pretty sure Jimmy will be the most economic solution. Sent from my HTC 10 using Tapatalk

I think your best bet is to contact Jimmy, at insat. He Can re-cell it and is held in high regard around here. http://www.bga-reworking.co.uk/insat-li-nmc-ebike-battery-10ah-24v-36v-48v.html You don't say what nominal voltage the battery is, and the readings you give don't add up. I don't...

Well, it's powered by a battery and controlled with a throttle. Sent from my HTC 10 using Tapatalk

I've never actually done this, but I have heard that cable ties can work as temporary snow chains on a bike. Only works if you have disk brakes though. http://lifehacker.com/5719594/zip-tie-snow-tires-the-cheapest-way-to-blizzard-proof-your-bike You can do something similar on alloy car wheels...

Correctly adjusted derailleurs are nothing to be worried about, they just work, and should continue to do so for a few thousand miles. After that, you will probably need a new chain and a bit of a service, any bike shop can do that for you for around £50. You deffinately don't want to be...

...and the answer will be 22mm, unless you need to know the clamp size. Sent from my HTC 10 using Tapatalk

I'm not guessing. I have experience with SLA's. Those are at the very most 14ah, but more likely 12ah. Just from the colour (and here I admit I'm making an educated guess) I'd say 10ah. They could be less than that if they are the wrong construction for the application, or old/miss-treated...

I assume this is a school project, of which the the CDT teacher should be proud. Unfortunately the physics teacher needs to be taken outside and beaten like a ginger step child. Sent from my HTC 10 using Tapatalk

That's not correct. There are 4 x 12v/10ah batteries. SLA will only give about 50% of it capacity at the sort of C rate required for a pedelec, so this machine has about 240wh of usable capacity. It will be extremely heavy, having two motors in addition to the batteries. I'd be surprised if it...

It's utter nonsense I'm afraid. 'low friction generator' is the problem here. Assumining the generator is 100% efficient then it can only generate as much energy as the front motor produces. Since neither the motor or generator are anywhere near 100% efficient, then transferring energy from...

Must be when you said: "turn her over and stick in her dropout". Sent from my HTC 10 using Tapatalk

A top tip for easy removal of grips is to use compressed air. Assuming you don't have a proper compressor, one of those little tyre inflators with a needle type ball inflator will do. Or one of these air duster cans will also work. Simply put the nozzle under the inboard end, give it some...

I asked Russell (I think) and he changed me over to a new name. It's better, as all your old post get re-named so you keep them. Sent from my HTC 10 using Tapatalk

I've no idea, as you don't quantify your results in any meaningful way. Sent from my HTC 10 using Tapatalk
