Human Power Generator Series

Bike Power Generator

If you are a cyclist, you know the value of winter training. But, do you know the value of your exertion? Your energy is being turned into heat by your trainer. Recapture your energy! The Bike Power Generator is the answer.

Options

The Bike Power Generator can be sold alone and comes with a 10ft connecting cable of your choice for $ 595.00. This is for people who already have their own 12V battery and/or inverter.

You can also purchase the Bike Power Generator with a Power Pack (we use Black and Decker's Electromate 400 and have a custom connecting cable to match it) The cost for this set-up is $ 725.00.

Finally, if you want to accurately monitor the power you are producing, you can use our Power Monitor that can be connected in-line between the Bike Power Generator and the Power Pack or a simple 12V battery. The cost for the Power Monitor is $ 325.00 to $ 360.00 depending on the type of connector you need.

There is more information about both the Power Pack and the Power Monitor on our website. Just go back to the Human Power Series page and you will see them listed in the menu on the left hand side of the page.

Product Description

The Bike Power Generator consists of a powder coated steel trainer frame holding a permanent magnet DC generator. Your bicycle (typical adult 27 inch wheel diameter) is mounted securely to this frame and the rear tire is positioned to turn the friction drum that has been custom fit over the generator shaft. The amount of electrical power that can be generated by the Bike Power Generator is determined by the energy available from pedaling the bicycle. The stronger the user, the higher the production of electrical power. A well inflated tire with a smooth tread allows for maximum contact and efficiency.

How much power can a cyclist expect to produce with the Bike Power Generator? The average person can expect to produce in the range of 150 watts sustainably, charging variably at between 10A - 16A. The Bike Power Generator has been designed with a generator capable of handling 20A of current. When used to charge a 12 Volt battery, this produces a maximum PEAK power output of around 275 Watts (13.6 V x 20A = 272W) or just over a third of one horsepower (One horsepower is equal to 746 Watts).One can expect the peak output only in very short bursts.

While it is possible to directly power some DC appliances such as water pumps, the Bike Power Generator is primarily designed to charge a deep cycle, 12-Volt battery or to contribute to a 12 Volt battery bank. Most household appliances require alternating current (AC) which requires a DC to AC inverter (see our Portable Power Pack). Certain DC appliances, such as DC lights, can be powered directly, but it is important to observe maximum voltage ratings to avoid damaging these appliances. It is usually necessary to use a voltage regulator or carefully monitor output with a voltmeter or multimeter. The output of a permanent magnet DC generator is variable - based on rpm and load.

If the Bike Power Generator is purchased on its own without a Power Pack, it automatically comes with a heavy duty diode- protected connecting cable. You can choose the kind of wire termination that suits your application. The most universal cable uses plier style clips to attach directly to the battery posts. Ring terminals (5/16) are also very popular..

The diode is built into a small in-line aluminium box and prevents reverse current from traveling back from the battery to the generator. The diode is rated for 35A. It is also a full wave bridge, which allows for pedaling in either direction regardless of polarity..
