An year or so ago I had constructed a windmill alternator - dual rotor with 12 on each N35 grade 50x25x12 mm sized NdFeB magnets, 9 coils, 65 turns of 15 gauge wire, 3 phase. This was entirely out of enthusiasm about DYI windmill. Thanks to this forum/board for valuable source of information and examples.
However I could not find a suitable wind site hence decided to adapt the generator as a pedgen. My college time bicycle was all rusted and still there with its frame / chasis in good condition, so I decided to use it and convert into a pedgen. This is how it has come out.

Nice ....I prefer metallic blue ...
The ideal would be to have it geared so pedaling at a nice 60 rpm crank speed and hooked
up to a 12 volt battery.....1 phase 25 watts, 2 phase 50 watts, 3 phase 75 watts or something
similar.
In my case 3phases on a EMC conversion is just right with a ratio of about 1:8 pedaling at 60 rpm pedals
is 5 mph on the speedometer is easy just pedaling a little faster to 6mph is making a little over 50 watts
and I don't have it set up too good for 7 mph nor am I in condition ,it slips and very hard to pedal for more than a minute.
5mph. is the true speed of the wheel , were it to be touching the ground.
Charging a battery is a better way to make use of a pedgen
Norm.
