DIY VIDEO 1 of 6 Permanent Magnet DC Pedal Power Bicycle Generator

[@MontgomeryPowell]

SO AWESOME! thank you so much for not trying to charge upwards of $50 for this info. You make it super simple for a novice electric hobyist! thanks!!

[@bicyclegenerator]

@lancerooke You can put a few drops of glue onto the set screw threads. The best to use is Loctite. If you set screw loosens up a lot it could be that your pulley is not balanced correctly.

[@bmq05]

Yes thank you this is what I needed to see. I didn't want to destroy my bicycle trainer.

[@bicyclegenerator]

@PatinOmaha FYI - the wire from the generator is size 12 AWG (American Wire Gauge) which is rated to handle up to a peak current of 20 Amps. When you are charging a battery you can hit 20 Amps of current for a couple of seconds if you are really great athlete. The charging voltage would be about 15 Volts DC. So Watts = 20 Amps X 15 Volts = 300 Watts!! you can have wire as thin as a single hair carry 300 Watts of power if the wire is at 300 Volts while carrying 1 Amp, that would = 300W

[@bicyclegenerator]

@sanjaydav Not sure which one is being used in NewZealand - can you clarify? We ship from the U.S. all over the world.

[@lancerooke]

@bicyclegenerator It hasn't popped off since I tightened it extra hard, but I purchased some Loctite anyway just in case it pops off again. I don't think it's the alignment. I am using a Schwinn World Sport bike and it's wheels are actually perfect for this application. Thanks for the info!

[@bicyclegenerator]

@Wahsayah If you get the PPG-R300-K then you will need just a blocking diode. Charge controller is optional. You don't need a charge controller if you have a volt meter hooked up to the battery and make sure you don't exceed manufacturer's specification for Max Charge Voltage. In most cases this is ~15 Volts.

[@bicyclegenerator]

@aymeey0 The generator is sold on the web page pedal power generator d o t com under the parts list section. It's a 300 Watt DC permanent magnet motor that works as a generator or dynamo. It comes with a pulley mounted to its shaft. Size 3L or 3/8 inches wide V- Belt.

[@BREGGREN]

One HELLUVA Great VIDEO - The Finest I've Seen!

[@bicyclegenerator]

So your profile indicates you are an 18 year old diesel mechanic? Impressive! I was under the impression that a fuel cell converts chemical energy to electrical energy. Where did you get your generator definition from? And the bike shops do call the round things with teeth a "Sprocket"? Not a pedal gear? Thanks for the input.

[@Dexter_Solid]

I would design the mounting plate for the alternator to be a bit larger, and have the mounting hole elongated so as to be able to adjust the tension on the belt, but otherwise good setup.

[@rainbowsalads]

i think it can take a 26" wheel with gears too,

[@bicyclegenerator]

@djsaimon2 The best way to go is to use 12 Volt light bulbs, and purchase the bike stand, the generator, the mounting adapter plate, the NC25A charge controller - which will be used as an over voltage protection circuit- to a dump resistor. The dump resistor come with the DIY wiring kit on the website.

[@bicyclegenerator]

This is an adjustable length belt drive system that can be used with full size adult bike, or children's bike. Either one is ok because you can easily add or remove links from this 3/8" adjustable length V-belt. All you need to do is watch the part of the video where it shows the belt length being altered.

[@launcheverything]

Suggestion: To solve the problem of adjusting the belt, rather than keep removing links, why don't you just incorporate threaded bolts into the alternator's mounting bracket???? Once the belt is reasonably snug, you adjust the tension by tightening the bolts, which pulls the alternator farther away from the wheel. Also, the rear wheel should be heavy, like 1 or 2-inch thick steel. This will be more difficult to start up, but once it gets going, it will be easier to pedal under high resistance.

[@createthisdotcom]

Hey, I'm curious about the math/engineering behind this. How can I predict how many volts/amps an electric motor will output at a given RPM when used as a generator? Does it get harder to pedal when the load is greater? I'm a self starter. Point me at some documentation or technical documents if that's easier. Thanks!

[@bicyclegenerator]

+createthis There is a rule of thumb that you can use to get this information. Take a look at a DC permanent magnet motor's rated RPM and rated Voltage. For instance 2800 RPM and 24 Volts. Then divide Voltage by RPM and you get 0.00857 Volts per RPM. So at 1000 RPM (Revolutions per minute) you have a theoretical output of about 8.57 Volts DC (Noisy DC that can be cleaned up by a capacitor). Now you apply a correction factor of something around 0.95 to 0.85 that accounts for losses in the motor. So using our example, a worst case output of a DC permanent magnet DC motor used as a dynamo generator would be 0.85 x 8.57VDC = 7.28 Volts DC

[@createthisdotcom]

+bicyclegenerator voltage is only one half of the coin though. what about amperage? Is it similarly linear?

[@bicyclegenerator]

+createthis Hello, yes you are right, take a look at my daughter's Voltage / Current measurements here: pedalpowergenerator.com/floating-ball-energy-display-bike-generator.htm

[@julieCCouture]

Thanks for all the info! I can't wait to get started with this project!

[@arseniyonline1234555]

in the future, would it be possible to have bigger generator, may be one that would require more resistance from pedaling?

[@aymeey0]

I am building a pedal power bicycle myself for a science project. I have been looking EVERYWHERE for a generator like yours, but I cannot seem to find one. Can you please tell me where it is you got yours? thank you! :D

[@bicyclegenerator]

@faststronghorse It takes about 30 minutes to assemble and take the tire off your back wheel and then put the belt on. The costs are: Generator $100, Stand: $80, Belt: $70

[@osvaldoperez3294]

Where can I buy the generator

[@essexgary]

Hi.Where did the pulley come from and are you selling the motor mount plate already made? if so can you give me details of how and where to buy and a price too. Cheers Gary

[@bicyclegenerator]

+Essex Gary Hello, the pulley is a common 2" diameter - size 3L (3/8") wide V-belt pulley. It has a 5/16" bore. It needs to be enlarged to fit to 8mm to fit this generator - permanent magnet DC motor called the "MY1016 scooter motor" , I bought it from chicago pulley. Best regards Brad at pedalpowergenerator.com

[@London_UK654]

It's gonna burn out motor one day. Thank you for the demonstration

[@CommanderRedVega]

Okay does your kit need anything else required to buy aside from the kit or does the kit include everything except a powerpack/rechargeable battery so I can charge the powerpack/rechargable for my appliances to run from? Like that mounting block at 1:07, does that come with the kit or what?

[@arseniyonline1234555]

every gym in the world could power themselves, from bikes to weight lifting, it can all be connected up to generate electricity for treadmills, light and music. integrate it with a grid in case it;s not enough

[@pedro75823]

Hey I am looking forward to do my own experiment, but first i cannot find the right DC generator. Could you please advise me on some names?. In every junkyard I have took a look they only have alternators and i am looking for a Dynamo generator. Cheers!

[@lancerooke]

@bicyclegenerator How can I make sure that the pulley stays affixed as a pinion to the generator? Mine has fallen off twice despite the fact that I tightened the set screw both times. Is there some sort of glue or putty I can use?

[@faststronghorse]

@bicyclegenerator How much time did you take to construct the whole setup? and can you give me a rough estimate of the costs required for the DIY bicycle generator? Thanks a bunch. :)

[@bicyclegenerator]

@lancerooke It is a bell motivator bike stand

[@rainbowsalads]

make a better demo too. and if it charged something up , might be worth having something like this, if the grid is cut off.

[@shivambhatt5352]

@bicyclegenerator For a school project I am planning to building a bicycle generator and I would appreciate it if I could get you advise. When connecting a motor to a battery, would you recommend using a charge controller or diode to get the energy from the motor to charge the battery?

[@bicyclegenerator]

Hello Shivam, you ask a good question. The short answer is either one will work. Since you are doing a school project then it would be better to use just a diode with a Volt meter on your handle bars to provide more of an educational experience. The Volt meter would be used to make sure you do not exceed the maximum Voltage of your battery. For example a lead acid AGM 12V battery will have a max charge Voltage at around 14.8 Volts DC. So by having the Volt meter on your handle bars you can verify that you are not exceeding this level. Best Regards, Bradley Whaley PedalPowerGenerator.com

[@jayshaw3971]

谢谢你的视频。

[@jmoney6652]

How do you find the bracket for sale?

[@arseniyonline1234555]

does it not come with wires connected to something already? i don't wont to bother with wire clippers and all of that

[@VideoClubMuenchen]

Cooles Teil ! Wo kann man das in Europa kaufen ?

[@ARICIULL]

What is te name of generator, where can I find one to by?!.... I really need one of this!...

[@bicyclegenerator]

Cristian Steclaru This generator is simply a DC permanent magnet motor used with kids electric scooters. It has amazingly large magnets and puts out DC Voltage up to 20 Amps of current. Ihave graphs posted on my website showing the Voltage output and internal resistance. This is much much cheaper than using a 3 wire PM alternator. You can buy the scooter motor for around $26.00 and then the pulley costs about $4.00 . You can find it on Google by searching for 300 Watt bicycle generator

[@sanjaydav]

Any chance of getting the generator you are using in NewZealand?

[@SIVPAO]

I'm looking for this kind of belt but cannot find out. Can you tell me the belt name or can give me a link to buy on eBay?

[@bicyclegenerator]

@djsaimon2 Yes- in UK there is electric pedals dot com

[@bicyclegenerator]

yes it can take 26" length wheel too. See comment above.

[@bicyclegenerator]

@arseniyonline1234555 You will be very happy with the amount of resistance if you go to your higher gears and hook this generator up to a 100 Amp hour battery to charge. This is very similar to riding at 15 MPH and feeling the wind pushing back on you. Then you go to 20 Miles per hour, the wind gets SUPER hard to pedal against.. It's the same way when charging a 100 Amp Hour Deep cycle battery or a 18 Amp hour Duracell power pack that is powering a television set.

[@lancerooke]

What brand bike stand is that?

[@lexus14blacklist]

open end adjustable wrench not cresent wrench

[@robertwhaley6325]

Good job R ad.

[@JayBenedictBrown]

Thanks!

[@bicyclegenerator]

+55commander Let me know if you have any more questions on this. Best regards, Brad at pedalpowergenerator.com

[@munmunnisharahman8157]

Assalamualikum, I am from bangladesh, i want to build a paddle powered generator for my mom. She lives in village, where load shedding is excessive. To run a water motor w-746, v- 450 ... 1hp. Will you help I am weak in english & know nothing about these things. ...

[@bicyclegenerator]

You would need about 7 bike generators to run a 746W pump. I can help you build something simple if you want. Best wishes, Bradley Whaley Electrical Engineer, Arizona , USA

[@pisocaceres9222]

you can see this system in the 70's film Soylent Green

[@midway27272727]

good info....thanks !

[@rithurajr8501]

can i put this in ma elctric cycle?

[@bicyclegenerator]

+RithuRaj r Hello RithuRaj, If you already have an electric cycle then most likely already have a DC permnanet magnet motor built into the hub of your wheel. This means you can use your electrical cycle as a generator by adding some addtional wiring to your system . Like a fuse, and a blocking diode. The question is what do you want to do with your electric cycle? Do you want to charge batteries or deliver power to lights? Best wishes, Brad at pedalpowergenerator.com

[@lboopathiraj_karaikudi]

NICE VIDEO

[@zorasingh4117]

Make the bicycle wheel weighty to maintain the RPM.

[@bradwhaley7639]

Zora - thanks for your comment - adding mass to the wheel can help stabilize the revolutions per minute (RPM) which in turn can help make the Voltage more stable, but keep in mind that does not make a difference when charging a battery or powering something with a regulator built in. Best Regards, Bradley Whaley - Electrical Engineer, Gilbert Arizona

[@PatinOmaha]

I have my doubts that the wires coming out of that generator can handle 300 watts of power.

[@UDSETIAWAN]

how much the rpm can result 100 watt on those generator?

[@bicyclegenerator]

Assuming we are going to operate at the 12 Volt range charging a 12V Battery: Assume a charging Voltage of 14 Volts with a 20 Amp Hour Battery. Then you would pedal a full size bicycle with the rear wheel spinning at about 5 Miles per hour. Thanks for asking, Bradley from Pedal Power Generators LLC

[@mmo8bcn8]

Why do you feel it necessary to over explain the most simple and logical processes? Removing a tire should be explained in less than 5 seconds. Unfortunately modern American vernacular has allowed for the legitimization of words such as tightness; such a colloquial, almost pigeon adaptation of the proper word tension. Also your chain is not tensioned properly.

[@bicyclegenerator]

mmo8bcn8 Oh then... you definately don't want to watch my other video here: kzbin.info/www/bejne/fH-VgpRpaLutaNE

[@ahwell9748]

Will it still work if i uses a AC induction motor

[@bicyclegenerator]

+John Pama Unfortunately an AC induction motor does not have a built in magnetic field so it is not able to be a generator dynamo. Best regards, brad at pedalpowergenerator.com
