This is the second doomsday exercise bike I've created. Its considerably easier to pedal and makes far more voltage than my first model which uses an auto alternator.
This model utilizes a homemade PMA which I made from a handful of magnets and an old cieling fan motor. This doomsday bike makes raw AC power , unlike the first one with the automotive alternator which is converted to DC for automotive use.
I demonstrate powering a 40x2 watt light directly from the newest exercise bike generator, requiring no batteries or inverters or any expensive devices to power things like the 80 watt light, or a cellphone charger.
I'm far more satisfied with this model compared to my first model, because this one is far easier to pedal, however I'm unsure if it makes the same amount of AMPS. The first model utilized a 60 amp auto alternator where as this newer model utilizes a homemade PMA.
Here's a link to a video of my second and improved doomsday exercise bike build/fabrication :)
