I must say, I have the pit bike with that engine, and it STINKS! the motor constantly was falling to pieces. If you ever build a motorized bike, please don't use this motor, save yourself a headache.
@John Brier I've been wondering about that, thinking a strong rider of a pedal bike going up a steep hill, and standing up on the pedals, puts out quite a bit of torque; and never worries about the chain failing under those circumstances. (At least, I don't.) So the engine only applies the torque needed to move/accelerate the bike and rider, which wouldn't make us worry about the chain if the rider were applying the same force to the chain. Do the bicycle chains often fail under engine torque?
@@stephenandloriyoung5716 So many things wrong with this build. A bicycle chain won't last long with the constant torque of the engine, and the gears won't either. Plus those sprockets can make it go way past anything safe and the derailleurs will disintegrate. Also you would have to use all the gears gradually to get up speed and the speed he clocked had no load, not realistic at all!
My respects to you bro, the net you raffled off with the electronic ignition and with the gear changes, the net if you search on RU-vid there is no other video where they do the same, you are the only one
@@ShortCrypticTales yea and where is the starter dude? I saw the relay and the ignition switch and there is something else left, the starter motor. You can't physically wire the engine up with some wires and hope it works. It's a f*cking patent you cant do this bc there is no starter on these 50cc engines, he just wired up the relay for the starter and while it clicks it tricks you into thinking it crancks up
Tremenda quedo me encanto el sistema de cambios que supuestamente frizaba los 99 km/ h (una bestialidad para una bicimoto) y me gusto mucho el arranque electrico
drill press, vice, welder and hand tools. without these good luck even though its not too difficult to do. but these tools are a must or it aint happenin!
These CAG engines are so superior to use on a motored bicycle! The re coil start and clutch make so much more sense.The only down side is the extremely poor mounting holes that just won't take much abuse and require rubber washers and very careful torque to avoid snapping chunks of the motor case with the bolts along with them. Lots of performance parts for these little screamers!
Yes I’m building one just now these engines are great to use once the carb has been charged and stronger clutch springs these engines also last a bit longer with the cooling shrouds extended I’ve had the 80 and 100cc engine kits you can buy to fit straight onto a bike in the past but the reliability of those engines are poor I’m keen to see how this engine holds up on my bike when it’s built
Basically it is called Luna, which in India 80's and 90's mens use to ride, but 60cc with 2 seater capacity, chassis bit heavier, and one thing, pedals were there to start the vehicle by holding clutch and few pedals, leave the clutch, here we go, ur luna is ready for a ride, when run out of fuel or some issues, pedals use to help riding it. This guy have removed the pedals, the whole video is super excellent awesome, but no pedals means, any issue arrives, u need to push all the way.
Check your states rules. In Utah, the moment you change the motor drive to a multi gear setup it becomes a motorcycle. Same goes for removing the petals. That mean, a motorcycle license, insurance, and license plate. Now if you keep the petals, you can have the petal side be a multi gear, but the motor drive side must be a single speed to stay a bike.
the song sounded like a broken fan plus the grinder sounds were like razor blades in my ears. The exauhst pip is still gonna fall off. they always do. and i usually share why they do and how to fix it. not this time. good luck
I tried to make one too without welding, but nah. The gear ratio were horrible. I had a less than one gear ratio and the sprocket was probably bent too. It could have worked though. I plan on building a motorized bicycle trailer. That way I can get power both me and my motor and put it on an off road bicycle. I hope I can post a video on it soon.
Looks like some good work to me. Never seen an electric start on one of those bike motors. I hope your braking system is s good or better than you motor and and gearing system!
Bet, I'll probably do this to my old mountain bike! If I remember correctly it has 6 gears and 3 big gears where the pedals are at, I could still reuse them for the motor right?
Thanks for the video everone, very nice, keep up the great work everyone ,hope to see An off road video of how it, pulls at low speed ,on light grade Trails. Go 2stroke Keep up the great work everyone ☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆
@@filipotv en el Video donde dice que hacer cuando no prende el motor ,en ese tipo de motor se le puede poner arranque eléctrico,gracias por su respuesta
That is almost exactly the same setup I used on my 1st build but with a go-ped engine. After lots of test rides and pushing it home very occasionally, version 2.0 i kept the ability to pedal home 🥴
Bella invenzione, peccato che questi cosi fatti veicoli per legge non possono circolare su strade pubbliche, altrimenti dovrebbero essere omologati, ciò vuol dire che devono essere targati e assicurati e per essere omologati non solo bisogna pagare ma un tim di ingegneri deve dare l' approvazione specialmente per quello che riguarda l' affidabilità e la sicurezza
Hello my friend, first of all thank you for your useful video. I have a 49cc 4-stroke motorized bike. I want to connect the ignition coil to the battery just like you. Can it be connected to this engine? I don't know how many volt batteries are needed. Can you help? Thanks.
FELICITACIONES... También quiero aplicar tu idea pero sin sacrificar los pedales y colocar el motor en la parte trasera. donde puedo conseguir esos motores de 49cc. soy de Lima Perú. Te lo agradeceria.
It'll do maybe 40 mph with a person on it. Tall gear ratios are great, but without the horsepower to get the rpms up in that gear, you can only go so fast. Nice build though. Those pb motors have pretty decent power and sound good when they rev too.
i wouldnt even bother with the front derailer. that can get stuck jam up! i would rather have all gearing on the back wheel. put the chain on the medium or middle sprocket. take out the front derailer system.
Очень интересно сколько проживут велоцепи и звезды под нагрузкой? Километорв 100? What resourse of chain and sprockets in real riding? One hundred kilometer?
@@jaydangier1110 you're right like I said before I can't understand why they don't do that every time they put a motor on bicycle you'll get a lot more power and speed from using the gears.
I would change the rear derailleur its too sloppy, front also. And a bigger tire ratio. Awesome build. Crap bike. If this was on a purpose built MTB it would be a super badass motorcycle!!
Doesn't matter what front or rear derailleur is used, the rear bearings in the pulley wheels will be dead in no time and the front derailleur chain guide will be worn through in a week tops at those speeds the way the chain is flapping. Not only that, the freewheel will either explode or be forever frozen after a couple weeks at even half those speeds under load. As a long time bike mechanic, it was cool to see how it was done, but those parts will never hold up under those conditions. Hell, even the bottom bracket will have so much friction, it could blow the entire frame in half if it gets too hot and destroys itself.
Сделал из велосипеда недомотоцикл, сделал заужение на выпуске, куча колхоза и инженерных просчетов... Без возможности крутить педали этот проект бессмысленный. Видео о том, как делать не надо.
