In pedal powered sound system the
electricity is generated by peddling the bicycle.
The power output
is 12 volts DC.
This can be used to power any 12 volt DC device or
through an Inverter to power AC devices.
The out put power is 65
Watts. Or for powering a Sound System of up to 200 Watts with one
Bike. the Ginger Ninjas us 4 bikes to power a 1000 Watt sound system.

Engagement
leverThe engagement lever consists of a thumb shifter and shifter cable that is attached to the generator mount. It is used to engage the rub roller on the motor with the rear wheel. It is usually attached in a convention place like the handlebars. With this leaver you can engage the generator as needed, even while riding the bike down hill charging. There is a return spring that pulls the generator back away from the Tire.

With the rub roller it rubs against the side wall of tire. With the bike shifted into it´s highs gear the generator will spin at about 2000 RPM s.

The bike would be traveling at about 35 miles an hour if it was on a center stand. He motor needs to be operating at this speed to to put out the necessary voltage. It can out put 13 to 15 volts at 65 watts with a load on the power out. Typically an adult in great shape can peak at 300 to 400 Watts in short "Sprints" or bursts of speed. Also for a long 60 minute bike ride a person in great shape can average 100- 150 Watts of power. So in this case the max power would be 400 Watts, and the nominal operating power would be 150 Watts. This system only produces a maximum of 100 watts because of the size of the generator.

This next graph shows the the watts
to voltage out put that is possible.
The motor is only rated for 5 amps. Going over that will eventually burn out the motor. When the Permanent Magnets get hot, they wear out over time. Over working the motor will cause it to fatigue and fail over time. To avoid this be sure and us the proper number of generators for the output load.
We have used this DC Motor as a generator for the Pleasant Revolution Tour and has performed quite well.

F, 15 Volt, Ultra Capacitor
The idea of using such a large capacitor is to enable Real Time use of the the power the generator produces. While having the ability to switch peddlers or pause with a load on the power out. Like a battery the capacitor stores energy, but only for a short time. (1.5 min. at 45 watt. Load) When peddling is resumed the capacitor can be charged very quickly, unlike a battery.
Is very important to being able to pedal the bike in place. It keep the rear wheel off the ground and stabilizes the bike. It is made of steel tube stock. It was designed with many revisions while in use on the Pleasant Revolution. It uses a plastic bushing at its pivot point to prevent wear. Has a return spring that keeps it out of the way while riding. Comes painted in enamel, in one of three colors black, white, and blue.
The indicator is very important to the peddler operating the bicycle generator. This lets the peddler know what the charge on the capacitor is. You want the capacitor voltage to be under 15 volts. It can be adjusted to a high voltage of 13.5 to 15 volts. It has 5 lights that increment at about 0.5 volts. This can be adjusted. The fifth light blinks red, indicating to the peddler that that they are over the high voltage.
