after a reduction gear starter motor... for an electric bike

Postby Psycho_Dad » Fri Apr 06, 2012 9:38 am

so im bored of commuting, i live in mt cook and drive my suzuki van to karori every day, i would bike but i work as a tree surgeon and biking up to karori is too exhausting for me to then slay giants

sooooooo


im building an electric bicycle and need a reduction gear system for it... many starter motors have such a system, so wondering if anyone here has a buggered starter motor they would like to donate to the cause of science!

i can come and pick up from anywhere in welly, i kinda need to get this gearing sorted before i buy up big on lipos, motors and speed controllers

if anyone here is interested by such a proqject ill get it all photographed and documented for people to check out

should be easier to build than my sensory deprivation tank proqject

If you have a bicycle with a total max power output of greater than 300 watts, it's a moped and the cops will have words with you about it.

cheers for that leon, i appreciate your input

300 watts off my legs on the karori hills sounds like relief to me(te aro climb kills me), my lipo battery i plan on using only has 177watt hours, so although my motor may be capable of doing such speeds, i coulid only maintain 300w for 35 min as it is

is the basic plans im working off, although i am not completely sold on it yet

but it all starts with a starter motor

:D

Just pick a part that shit. There should be heaps out there and then you would have a choice.

You'd be better off with a direct drive hub motor.
I'm in the process of building/evolving my electric bike, currently running a 72V system with a 1000w rear hub motor, not exactly legal, but the rules mean that a legal e-bike would be pretty much useless in Wellington (unless you somehow manage to stick to the flat). Mine gets me up Ngaio gorge at around 45kph pedal assisted. have a look at http://ev.geek.nz for some good info on what people are building. talk to Daryl @ www.EVlab.co.nz for motors etc (he's based in Upper Hutt).

is there a reason they seem to have no motors for 700c wheel size?
