Building a pedal power bicycle 12 volt generator, ghetto style - Page 13

There are a few different types of kick-stand,
so you might not be able to make a universal system for holding every bike stationary.

But, it's not going to harm the bike to remove the kick-stand.
I removed the kick-stands from our two new bikes, so I could bend them in a vise.

Took me about about 2 minutes to re-install them.

A lot of bikes these days aren't sold with kick-stands.
Many people have a bike hook in their garage, and park in public bike racks
when they are out for a ride, so they can chain their bike to the rack.
If they have to chain it to a tree or signpost, they don't need a kick-stand.

A friend asked me to look into pedal generators -- how does this homemade one work? What can you power with it?

Looks great!

Does it have a coasting ratchet on the flywheel?

Not a lot. Maybe charge up your Ipod, while you listen to some Itunes?

IMHO, use that extra carb energy to earn (shoveling snow?) enough money
to buy some solar PV.. That gets you a green power source..
Need to workout some more? (I know I do) Add to the size of your PV array!

I use a little 10W array w/ a charge controller & (old)12V car battery
to run my 12v RC nicad charger and some ham radio gear..

Of course it's all low power stuff.. Things like this e-scooter, won't work..

Could you post something on the exact geneerator you used because when I look up a permenent magnetic blower motor very similiar motors come up but not that same. What type of car is it from? What's year?

Way back in the 70s I made a bike stand with a friction coupled generator that you could just set the bike in, climb on and peddle. I picked up a couple of identical used front forks at the bike shop, cut the tail off of the "Y" welded them to some angle iron with a spacer of a length related to the bike to be used between the front and rear forks, to stabilize the frame. The generator with the drive tire was fastened to the rear fork. The forks are upside down of course. All one had to do was drop the bike axles in the fork groves and you're ready.

Piwoslaw,

it is a different kickstand, if you go to our last post you can see pictures of what we are dealing with....thanks for your help
if ANYONE has any ideas on how to help us out please don't be shy!!!

ScienceWiz · 12-16-11, 04:11 PM

I am trying to do this engineering design on my own. My only problem is...finding a suitable generator such as the one used in the video. I've been shopping for one and haven't had any luck. What is the name or serial number of the generator.What year is the generator. Who Makes it? Thanks!

Please use "simple-minded" language since I'm not familiar with it.

The one in the picture above looks like a permanent magnet electric scooter motor.

250W, 24v Electric Scooter Motor

That's a good idea.. This one looks ready for a bicycle chain..
