Interesting point about the fiesta. I wonder if that was using two controllers or one with enough power to provide maximum amps to both motors. Mind you, a tilt bed can be pretty steep. The cooling will have to be investigated too. With full current available to both motors a few hill starts could l...

Yes, I have no problem with chains. They wouldn't even be too noisy if enclosed. Interestingly though, the small wheels on the 126 mean the shafts would be spinning at 1100 rpm at 60mph and, as the eteks are at about 3500 at 72 volts (from memory) I would only need about 3.5:1 so the sprockets would...

Thanks Jeremy. I had the feeling (and it is only by the scientific measuring system known as 'feel') that, in the bike case, the losses were greater but it occurs to me now that most shaft drive bikes have two sets of helical cut bevel gears as their crankshafts are accross the frame and the drive i...

Transmission losses

Here's a question for the techies.......... Just how much power do we lose through various types of transmission in a coverted EV? I've always been a biker and, over the years I've been led to believe (by bike mags, hear say and experience) that shaft drive bikes lose a lot of power in the bevel dri...

I've got a Zapi twin motor controller in my cupboard which is designed to run two motors with differential power control.


I meant the controller, not the cupboard. In case my lack of punctuation left you wondering.

Hi, those motors look great. Are there any more where they came from? I'm too green to give any help with the mini, I'm afraid, but it sounds like a sound idea to me. I've got a Zapi twin motor controller in my cupboard which is designed to run two motors with differential power control. It's rated ...

The law and how (not) to break it

Does any body have the definitive law on self built or converted electric assisted bikes? If I build my own, does it have to have a pedal pressure sensor? If I fit a 200w 24v motor and then run it at 36 volts, who would notice? After all, officer, it says 200w on the motor plate! Any comments peeps?...

You can definitely get chain driven diffs. Do a google on Trike conversions. They use them to drive a car axle from a chain drive motorcycle engine. People have been known to put big bike engines in things like fiat 126s with one of thes as well.

Interesting thread, this. I've been giving it a bit if thought lately. I'm working on a fiat 126, which weighs in at about 500kg but the suspension's a bit weedy for carrying batteries. If I didn't already have the fiat, I think a Reliant Fox (sort of Kitten pickup thing) or even a Kitten would be g...
