## Overview

The 300 Watt Bicycle Generator is a durable, air-cooled DC generator designed for human, wind, or hydro power input. It delivers up to 300 watts peak power with a variable output voltage from 0 to 40 volts DC and a nominal current of 15 amps. Featuring a 3/8" belt drive pulley and 6mm mounting holes, it’s compatible with popular scooter motors like the MY1016 for cost-effective DIY energy solutions. Its ball bearing shaft and ventilation holes ensure reliable, heat-managed operation, making it ideal for sustainable energy generation on the go.

## Description

This DC Generator can be driven by human power, wind power, or hydro. The 3/8" wide pulley has a 2 inch outer diameter. You will be able to mount this generator to a bike stand using an adapter mounting plate. You can save more than 50% by making your own. Do an Amzaon search for "MY1016" scooter motor and a search for 2" V-belt pulley 5/16" bore. Or you can do a search for desertcart product code "B00T6CKSGY" It may be a big surprise, yes any DC permanent magnet motor also works as a DC generator. The MY1016 scooter is very robust engineered to operate in harsh conditions. It has ball bearings on its shaft as opposed to brass bushing bearings which are found in most cheap motors. To make your own, the basic steps are: (1) Remove the nut and gear off of the MY1016 scooter motor (2) Measure the shaft of your scooter motor (Usually 8mm). (3) Drill out the 5/16 inch inner bore pulley to meet the size requirement mentioned above (4) Grind a flat spot on the shaft of your scooter motor / generator where the set screw from the pulley can rest. (5) If you are really ambitious, you can take the MY1016 permanent magnet motor apart and drill holes in the sides to allow cool air error to enter so it doesn’t get too hot while running at 15 Amps output or more. It is very difficult to put it back together because the brushes that touch the armature are spring loaded and get in the way. NOTE: The generator shown in this listing has already been modified with these ventilation holes for you.

Review: Over Priced! - I bought this motor for a bicycle generator and it works great when used as a "pulley system" but does not work as a "direct drive" by putting the tire directly to the pulley/rotor. My guess is it can't handle the additional RPM's running direct but the motor does work well with the pulley. The problem I have is the motor I received does not look like the motor pictured. In fact, it looks identical to other motors sold on desertcart for electric scooters, search (Electric motors: Razor E300 & Ampflow P40-250). These motors seem to have the same spec's as this motor and are selling for around $50. In regards to the "specs", this motor is advertised in the product description as being capable of producing 40v, yet the spec's listed below the product rate the motor at 12-24v. (I have reached around 35v without a load with this motor and can charge 24v batteries). DO RESEARCH ON OTHER MOTORS BEFORE PAYING $200 FOR THIS! The back of this motor is cast with a company name of "UNITE MOTOR CO." I bet the same is cast on the back of the less expensive Scooter motors. The scooter motor's come with a gear or cog instead of a pulley but that can be changed.
Review: Great product - Performed exactly as described. - This product is excellent. Performed exactly as described. Came with an information sheet describing how to use it. It ran for over 2 hours with no excess heating. It was able to charge multiple 12 volt batteries with no problem.

## Questions & Answers

**Q: does direction of rotation matter for output?**
A: If you want to rotate clockwise then connect the negative wire (black one) to the negative one of the thing you want to power.  The red one should go with the positive end.  You can rotate in the other direction, but then the black wire is positive and the red one is negative so you just have to keep that in mind.

**Q: What are the lowest rpms that it can run to produce roughly 100watts? OR what is the curve?**
A: That is good resistance,  the answer is based on what the resistance is of what you are trying to power up.   Are you going to  power up a light?  A battery?   A cell phone?    Keep in mind that nearly any electrical system is less efficient at lower Voltages because of losses due to resistance in the wire and in the armature of the generator.    Is efficiency an issue?       Making the assumption that we are going to run at 500 RPMs (revolutions per minute),  then you would see approximately 3 Volts DC coming from the generator.     If you want 100 Watts of power at 3 Volts then the current going through your load would need to be  about 33.3 Amps     The generator is not rated for that much current.  So if we double that  speed to 1000 Watts,  you  would get about 6 Volts from the generator.   At this point you would need about 15 Amps of current to deliver 100 Watts to the load.    6 Volts divided by 15 Amps would be   0.4 Ohms resistance.   (Volts / Amps = Resistance).    Does this answer your question?   Best regards and good luck with your project,  Bradley Whaley  ELectrical Engineer  Pedal Power Generators

**Q: can it be used with a bicycle in movement or only a stationary one?**
A: When you attach this generator while moving it will add resistance to your pedaling so that you will have to work harder than normal.  So for instance if you wanted to put a 20 Amp Hour 12V Battery onto your bike and charge the battery while you ride the bike around town.   This would make it very hard to make your bike go faster than 5 miles per hour because it would place such a drag on your tire.  If you installed a button on your handle bars for regenerative breaking,  then you could use this button when you go down a hill or only when you want to stop the bike,  that way you could harvest the kinetic  energy  (1/2 x Mass x Velocity)  from your bike and put it into the battery.

**Q: Can it be used to charge a 48v ebike battery?**
A: You will have to have a inverter On a bike this gen. will make 12v or 24v. unevenly.  That is not  the gen.  It's the pedaling on the bike. If  you put a charge controller for a wind mill it will even out the highs. and the lows. Then invert to 48v

### ⭐⭐⭐⭐ Add a grid-tie inverter? :-)
*by N***E on February 15, 2012*

It seems to me that this $110 grid-tie inverter can make your electric meter run backwards if you are not using more than 300 watts of electricity in your house: http://www.amazon.com/Inverter-Converter-System-10-8-30V-Efficiecy/dp/tech-data/B005N2WHDI/ref=de_a_smtd And why buy the $499 kit, when the generator and mounting plate and adjustable belt and bike stand costs only add up to $429?
