This bike generator can deliver regulated DC
voltage to low power items such as:
- Ipod (through 12V cigarette Lighter adapter)
- Portable DVD Player
- Power a 7 Watt 5 inch black and white
- Charge cell phones (All Types) using
cigarette lighter style plug. Some one in their mid teens or
higher can charge 5 or 6 phones at once.
- Charge a car battery through a 5 Ohm power
resistor. If you don't use the resistor it is too hard to
- Supply power to Playstation
(PS2) Video Game
- DC Fan
Generator Start Up Speed
23 Miles per hour ( 300 Rear
Once you mount the bike and pedal
fast to hit the startup speed of 300 RPM, the generator will
kick in. After that you can slow down and pedal at half that
speed. RPM stands for revolutions per minute.
Regulated DC Voltage Output
14.8 volts Direct
This is the same voltage that U.S. cars run
at. After traveling through your car's electrical
harness out to your cigarette lighter, the 14.8 Volts droops
down a bit to around the 14.0 Volts DC. So all of the time
you've been thinking that a car runs at 12 Volts right? It doesn't.
The only time it is at 12 Volts is when your engine is off and your
are measuring voltage from your battery.
20 Amps (4 Amps
Even though the
wiring for this project can handle 20 Amps, you will find it
extremely hard to pedal when it is putting out more than 4 Amps.
This is because the the alternator is innefficient.
This design uses a 68 Amp Car
. But the 12 Gauge wiring size used is
only good for 20 Amps. If this bike is hooked up to something
that draws 20 Amps of current, you'll be putting out 296
Watts. At that rate you'd be wiped out after 60 seconds
If you want to go gonzo and use
all 68 Amps, then use 4 strands of wire in place of 1 and buy
fuses rated for 68 Amps.
296 Watts Max (40 Watts
This bike generator will be able to supply power
to low Wattage items such as cell phones, Playstation
and small DVD players or
TVs. Anything over 40 Watts will be
Too hard to pedal.
Formula for calculating Max Watts
is: Volts X Max Current = Max Watts. So in this case we
have 14.8V X 20 Amps = 296 Watts
Regulated AC Voltage Output
110 Volts Alternating
If you decide to implement an
AC inverter into your design, then it will provide you with AC
power needed to power low wattage items like:

Road bike or Mountain bike with "Quick Release"
The Ascent bike stand is
supposed to work with a road bike or mountain bike that has the
quick release lever. You know the kind that doesn't
require you to use a wrench to remove your bike tires. You can
get it to work with a regular bike axle that has nuts on each end,
but the risk is that the stand may release the bike when you are
riding it and cause personal injury.
