Clearly, in this day of global warming, a necessity, not merely a luxury like bright lights.

I concur. I would buy this right away for my 80cc build

Absolutely! I've seen a few riders modify the charging base, so it acts as a holster for the battery. Clicks in and out for quick battery changes.

Yeah but it’s annoying just like u

Nah, it's been done. Too simple.

JAFO I'm not aware of who that is, but, thanks? I think?

Will do. It's currently unavailable but I'm working on revamping it to eliminate the big hole in the side cover,as well as a brand version that will be completely encased inside.

Cody Watson , I've done something similar to this for a rider in Canada. So yes, I'm sure we could work together to get you the rig you need

Those exist now. Its the yd100 I think. Problem is that the internals have alot of plastic and a small chain drive next to the crankcase. Could be problematic if you don't completely re machine parts in metal. Its like 280 bucks. It has more torque than stock and has centrifugal clutch

@@dankennedy8757 its the bt 80 and its shit but people have done custom work on standard engines to make it work dunno how but its been done

I have two of the electric-start 2-stroke kits, bikeberry sells them, and they are called BT80's, it's actually a quality kit except for the pull-start, they have little plastic ears that pop out and turns the engine when you pull it, when the little ears break-off, it sounds like the engine is going to lockup any second, other than that, I love them.

@@jerryb1234 never had trouble with any anbull

Cory Miller , yes that would be optimal, I might think on that idea. Have a bearing included in the kit. Since the end user is the one to drill the hole in the side cover, I didn't want to make it"the hole had to be exactly yadda yadda yadda size, our it won't work". Lol. Without the seal, there's a little more room for slight error with the hole size, with the sacrifice of a completely sealed side cover. But, if done carefully, there's very little room for crud to get in there. But I agree with you, sealed would be optimal.

Two alts would be excessively cool on my fat bike too.

elitew4rri0r _ Good idea, but this is a generator only, it doesn't work like an electric motor. Some of the 49cc pit bikes have that function, where the starter turns into the alternator after the bike has been started.

Bill Collins I'll send a pm

Thanks brother,,, much appreciated.

Where there's a Will...

😅😅😅😅

I haven't seen that. I have seen the auxiliary charge coil that goes inside the case,but the power it puts out is negligible,as there's not enough space inside the case for the windings needed to produce real usable voltage and amperage.

Cody Watson , it's the cinch that's really close. The actual alternator is inside a steel guard that's clamped inside the chrome cinch, and is actually about an inch or so away from the exhaust. But depending on your bike, you could move the downtube clamp down a little farther away from the exhaust.

Bill Collins , yes, a PMA still outputs ac voltage. So a regulator/rectifier would still be necessary, unless it was a very low voltage output, and you plan on running only filament bulbs, as they can run on both ac and DC, as long as the voltage doesn't run past their maximum input voltage ( that for if your using ac voltage with no regulator)

awesome.... thanks for the info...

It's advertised as 12 volts. It will achieve that bit only at wide open throttle. And only gives about 1/4 of an amp. There simply isn't enough windings on the coil to produce any real usable voltage/amperage. Plus it shares the magnet with the spark plug coil,and robs you of power for the plug

I've been using An auxiliary coil for over 30 years to charge my battery. It puts out 1.3amps at Idol. I have no issues with it pulling power from the bike or the coil. I am charging a 18 amp Hr lithium battery with it and it runs everything you can put on a bike, headlight tail light turn signals and all my accessories and the best part about it is it's all inside the case and watertight, the only thing I have external is the battery which is in a weatherproof enclosed case, along with my voltage regulator and fuse box. If you can handle basic electricity and Ohms law this is the way to go, especially if you're on a budget. Keep it simple and factory and most important. Have fun doing it.👍

Randall Russell no sir, this is a 12 volt system, it would never do what you need it to do.

Get an adjustable dc-dc boost converter off eBay, even high amp ones are cheap

I'm not sure, but I believe some pit bikes use that same idea? The starter becomes the generator when it's not being used as a starting device.

Older VW's did this as well

In a stock 66cc the only test i had was with and without the generator installed,driving the same 2 mile course around town. I did notice a 1-2 mph difference in top speed,but no way to tell if it was the generator or possibly headwinds/weather conditions. I didn't notice any difference in acceleration. Top speed without it was 37mph according to gps speedometer. 35 to 36mph with the generator installed.

Agreed. Pros and cons no matter what. I guess it just depends on the individual and their particular riding habits and road conditions./weather conditions.

Good eye. You're exactly right. It works perfect for the application.

It works perfect! Lol.

Eclipse Gaming , they are made here in my shop.

Do you have a web site or email to see your products sr!?

Agreed Shane. But as long as your load doesn't exceed the input,there's only a negligible load put into the engine. In past tests I've only experienced a less than 1mph difference in top speed,and no noticeable difference in acceleration. At half throttle, the alternator is putting out 14.7 volts dc and 7 amps. A fully loaded led lighting system should only draw about 3.5 amps. That's a great point you brought up though.

Drcool52 , yes the little mini gen that doesn't work. It's impossible to get any workable voltage out of those small windings, no matter what the claim is. There just isn't enough room under the side cover to put the amount of magnet wire you would need to achieve any real voltage. You also have to take into account that you need rectification of the AC voltage coming out, to make it into usable DC voltage. After experimenting with that particular"mini gen", the most voltage I could ever get out, at wide open throttle, with no load on the rear wheel, was about 3 volts AC. After rectification your left with around 2.2 volts DC and 1/8 of an amp. My system is designed for people who want to run full lighting systems on their bikes, as well as a few accessories.

Thats why you get an atv battery and a rectifier. During the day your battery charges and then at night you should have plenty of power to run a lighting system as long as its led. As for your claim that you only got 3 volts and an 1/8 amp I doubt that a bit. I'll come back here when I get one and show my results. But I do respect that you actually argued your product instead of just deleting my comment.

Drcool52 Not at all, I appreciate the input. I've had a couple mini gens, one from the eBay seller"mightywonderful creations" and another from gas bike. The eBay seller also sold a small external black box that zip tied to your seat post tube. It contained a half wave rectifier circuit, as well as a few voltage doublers. That's how he was able to get that small winding to produce 12 volts from 3. But, if you double your voltage a you half your amps. That's why it just can't work. What can you run from a 1/8 amp? Maybe a small flashlight LED, if you're lucky. My system was designed so you could use anything you want, 24 hours a day, lights, USB chargers, etc. It's modeled after a motorcycle system, just not as many amps. Mine tops out at 14.8 volts and around 8 amps. My complete LED lighting system only draws 1 amp. I have the voltage regulated and rectified with a universal 4 wire regulator/rectifier. This system is the culmination of about 2 years of experiments. I can give detailed answers but that would not be in this thread. Lol.

Drcool52 Been looking for that thanks, but how many lumens of light where do you get the lights? I got Solar lights got over 7500 lumens but its battery I was thinking of having it run off magneto so I can run day and night without electric drain loss.

You would have to find a light you can wire up. Theres plenty on ebay just make sure its a 12v light

Hi Keith. The charging system hasn't been produced for a couple years now. Parts prices went through the roof and most importantly, the company that made the alternator itself went out of business.

Cody Watson , currently the alternator kits are sold out, but usually can be found on the website. www.djwillk.wix.com/vbbl

251omega actually with most standard pedal cranks, they clear by about a 1/4". It's designed so most riders won't have to buy wide pedal cranks. That saves money. Good eye though!

Well, I just adapted one of those 80cc engines to my 1981 Stump-Jumper and the engine was too wide for my cranks. I tried to get a set of offset cranks for my Shimano Bio-Pace chainrings but not available. I slid the engine up the front tube and made a cross bracket for the rear mount. I had to lengthen the chain about 7"... works great! I would like to find rubber motor mounts, and an engine-mounted chain-tensioner pulley that's loaded with a heavy spring... chain keeps getting extra "play" as the stock pulley vibrates out of adjustment... hard to clamp it onto a tapered tube and I don't want to drill an index hole...!

The LoL Post around the world www.djwillk.wix.com/vbbl You can check it out there. There's contact info on the site, to get a hold of me to order. Thanks.

bradley morgan gram force millimeter? Decimeter? I can't remember. But it's a miniscule amount. With my lighting kit only drawing about 1.5 amps, and that's with high beam, brake lights and a set of turn signals blazing, the generator has no problem keeping the 12 volt 5 amp battery fully charged. It's putting out 12.9 volts and close to 4 amps at idle speed, and then 14.8 volts and close to 7 amps around 1/2 throttle. That's the bike being under load, with 180# rider. Under normal lighting conditions, headlight on low beam, and just tail lights, the current draw is 0.86.

that's not bad, pretty efficient lights it seems. but torque units are a measure of force (usually newtons in SI) multiplied by a distance (meters). so a torque of 1 newton meter will rotate a wheel that's one meter in diameter with a linear force of one newton along the outer rim.

bradley morgan thanks for the explanation, I was trying to explain the necessary forces needed to run the generator. It's almost negligible, but lacked the correct terminology to explain it so most could understand. I know it uses neodymnium magnets with North/South running the length of each magnet, so while it's being attracted to one set of windings, it's simutainiously being repelled by the previous. It's quite a remarkable little unit. Took a bit of research and a chunk of my own change in failed attempts before I found it.

Matt,thanks for the comment. This version of the charging system is no longer in production. I am currently working on version 2 which will be a totally enclosed system. I post updates and pics on my Facebook page. Heres the link. Thank you facebook.com/Verybrightbicyclelights/

The pulley gearing is designed to work from the rpm of the main shaft, depending on how fast or slow the jackshaft spins, would determine the final output voltage of the unit.

Will Kidd Okay where do I buy this kit?

@@monkeyboy991000 , normally from the website, but I'm currently sold out. www.djwillk.wix.com/vbbl

Wish .com has them- $115.

Good question,T.J. , I have other videos on KZfaq showing the alternator working, and I'm also a member of many motorized bicycle pages on Facebook. You can look up very bright bike lights on Facebook, or under my name, Will Kidd. I have many happy owners of the alternator. You could ask around in there, also have a web site, visit www.djwillk.wix.com/vbbl. My number is listed here in my logo, and also on my web page.

s14duma www.djwillk.wix.com/vbbl but they are currently sold out.

@@djwillk thank you!

Lol. I can do that.

Will Kidd I have to 80cc Motors I need to start charging batteries with this is the best idea I have found yet there is not a place to buy these online do you have a location are these customes and how can I buy these

You can contact me directly at verybrightmotorbikes@gmail.com, and I'll get your direct contact info. I can give you all the information you need on the charging system.

I appreciate the input. But those " 12 volt coils" that go inside the case dont put out any real usable power. You possibly get around 12 volts at wide open throttle, but only about 1/4 of an amp. You cant charge a battery with that tiny amount of power. The coils simply do not have enough windings to produce any sort of usable dc voltage. I tested them in depth before building mine.

@@djwillk Unless you use it to charge lithium batteries maybe.

@@djwillk I apologize for sounding like such a dick, clearly, you have done your homework and know what you're talking about. I'm thinking about buying a high compression head, any input on that?

@@GhettoRanger01 you don't sound like a dick at all. Lithium batteries can't be charged using a "flood charging" method,which is what those in case coils,and my system as well,utilize. They would destroy the Lithium batteries and possibly cause s fire. No bueno. High comp heads are nice but i believeyou'd need a little internal engine work to really make them sing. Not my area of knowledge really. I just make accessories..

zakarya hamzeh that's incorrect. This generator only takes 0.05 nanograms of torque to keep it going. That's less energy than is used to snap your fingers. It's a zero drag alternator, that's been field tested for over two years.

@@djwillk How did get that statistic? Surely you can't measure that.

Dr Din why not?

@@QuinnHartmann Do you know how small that value is? Also, nano grams isn't even the correct unit for torque, it's newton meters. Btw, 0.05 nanograms is 5*10^(-11)g. Even if he meant to say newton meters, such a small amount would suggest that he has an impossibly efficient system lol.

Different strokes is why. VBBL lights will pass a dot inspection to get your bike street legal, in States where it's viable to do so.

@@djwillk all I did was I want to Walmart got some led strip and got a battery on ebay hook it up and it work just find....

@@djwillk there's a video I made how I got my lights hook up. It's just as bright then on this video and you are running down your power on your engine meaning it won't go fast as it should.

@@derekthompson6653 I agree. I've got some lighting systems that are rechargable, so no alternator, bit over also got systems out there that use a battery and my generator system, that have been going for years. I believe options are good. What might work for one, might not speak to another.

@@djwillk I agree with you too.
