Homemade open crank motor bicycle

Close up view of the engine at 3:35.
Hope you enjoy!

[@grandpaseed]

thank you for not putting some crap music over the video I get so tired of lame music overlays, great motor congratulations on the build.

[@StupidEarthlings]

That really is worth something, especially the retarded volumes that the kids use, as they cant edit well..

[@MemphisApplegate]

Robin Hood vs nobody, as nobody is going to challenge your engine building skills. Man, if you designed and built that yourself you are a very talented guy. Seems like a lot of guys take lawn mower engines and rig them to a bike, no big deal. But that engine is a WORK OF ART, and I don't think many will disagree with me.

[@robinhooodvsyou]

It is a homemade engine, but I also have a couple of bikes with lawnmower engines on them, thanks for your kind words !

[@godshumbleservant1472]

God bless you, and He obviously blessed you with a n outstanding mechanical vision and the hands to make it work. Brilliant, simply brilliant!!! I love it all!!!! That is by far the coolest bike engine I've heard. Really digging on the build!!!! You should teach people how to build these, and who knows what other fantastic ideas are in your head and the people you inspire? I am loving the positivity of your video, too!!! Keep up the classy builds!!! Stay blessed

This isn't steampunk, this is gasoline punk! Wow, an open cranked 4 -stroke engine- powered bicycle! Fantastic job of home design and machining! Good work :)

[@SquillyMon]

WOW....THIS IS A FANTASTIC ACHEIVEMENT!!! I am a mechanic and fabricator as well so I can appreciate the time, EFFORT AND SKILL this project took to pull off as well as you have. I don't say this often but you are EXTREMELY TALENTED... We people seem to be too far an few between these days....Nice to see that someone else holds the basics PROUD AND TRUE. WELL DONE INDEED!!!

[@robinhooodvsyou]

I think you`re over-estimating my skills to some extent, but THANKS FOR THE SUPER NICE COMMENT !!

[@SquillyMon]

No Sir...I am NOT Over-estimating anything. Like I said...I am basically the same type of guy that you are. We can make anything using items that have no business being utilised. We are creative, we are fabricators and we LOVE a challenge...even if its just for FUN. So no...I see exactly the type of guy you are just from this project of yours. My hat is off to you Sir. You should see some of the things lying around my house man...LOL Like a Mad Scientist got loose around here and made crazy stuff nobody ever thought of...or maybe never needed either...but hey...IT WAS FUN!!!

It's funny to me how wise people can take something that is complicated and make it simple. Others take something simple and try to make it complicated. Great job, and thanks for sharing.

[@ducati1957]

Excellent work young man. I'm very impressed with your ability to create something from nearly nothing. A thoughtful blend of existing equipment into a very cool looking exposed engine, You are a very skilled integrator. Keep up the great work! I love the chain drive cam shaft and open valve train. Very sweet. You've created a work of mechanical art, really.

[@neardood1]

Gotta hand it to whoever built this, they sure had skill and determination.

[@nibbunrep]

What an inspiration your engine is! I love the old timey hand crafted antique quality that you have implemented in its construction. Many tinkerers and builders who love the old style early 1900s motorbikes could emulate this type of motor or variation to homebrew your own modern day antique machine.. well done sir, well done!

[@IcechickenSr]

robinhooodvsyou this thing is really cool, you did a very nice job, and now after all that hard work you put into it, you have yourself a real good starting point and completely functioning prototype. From here you can really go to town tinkering away and getting things fitting nicer, working nicer, looking more pretty ect. I think you could have yourself a neat little seller here. It seems to me like it is lacking a lot of power,I'd imagine you need a larger carb, or maybe it's just not opened up very much because it starts to choke and load up, in which case one could simple snag a governor off an old tractor carb and use the levers and mech's and have a nice mechanical govern'd setup that can keep itself running smooth when it begins to load up and run out of power etc. just an idea. Great work man! Cheers, IC.

[@franksgarageandcustoms8321]

[@Replevideo]

Very nice piece of engineering. Such engines were around back in the 1960s like the Power Pak and Berini. Your set up is very like the Power Pak, except that was only about 50 cc. At the time special steel reinforced tyres were available for use with these friction drive engines, but I don't know if you could still get one. A standard cycle tyre will not last long.

[@schabanow]

You guys are talented. It was like real Music for me. Thank you very much for your video! A little bit unpractical for our country (the roads here is often mud and/or water, dust, etc.) but really BRILLIANT. Thanks again!

[@vincent7520]

Very nice !We had the same in France called the VELOSOLEX the engine was more compact and on the front wheel.From 1946 to the mid 80's they sold millions, it was the cheapest indidual motorized transportation.Engine was more compact, gas tank was on the side of it, cylinder was on top, flywheel was on the other side of engine. Headlight was incorporated to the engine. No acceleration system, but a decelaration system by cable, and ebgine coul be lifted by a small handle behind the cylinder. It was 45 or 50cc 2stroke engine.I had three of them when I was a student and in my early 30's. It was perfect for errands in town'I do regret ut sometimes : now we're asking for more performance but basic objects had a lot to say for themselves although it is true that on icy and muddy roads riding the SOLEX as we called it was sometimes a challenge !!!However it couldn't meet pollution standards these daysI was told the SOLEX now has an electric version but I'm not sure. You should google VELOSOLEX or SOLEX for more info. Good job anyway !!!

[@robinhooodvsyou]

I`m very well aware of the velosolex. In fact, the very first motorized bicycle that I built years ago was sort of based on the same concept. Thanks for the comment !

[@1JohnMills]

There is a "solexmillenium.fr" (a French website). But, production stopped around 2006 (and, after 1988, it was already on the decline).

i,m a professional auto mechanic and your little engine is very, very cool. the whole thing is scary but cool. watch the grease cup bobbing up and down. damn that's the most mechanical machine i.ve seen in a while

[@JackpineGandy]

wonderfully conceived and executed project! appears to be what would be called a total loss lubrication system, just like the very early racing motorcycles. I think I'd like a brake, somewhere, but that's just me. I like this project! Well done!

[@torchyboyz]

Wow, what a cracking job you have made there. Well done, very imaginative

[@haistandardstv-music4035]

This is great for teaching purposes :) because all the mechanisms are very visible. It also has some disadvantages but it's for sure very interesting for students to study this also.

[@Iflyagrasshopper]

Great engine! The best way to understand a 4 stroke engine is to see it in action! Sounds 1,0000 times better that a weed whacker motor!

[@trentonjennings9105]

Very impressive. Reminds me of the developing technology of early 1900's when motors were being added to bicycles for what became motorcycles. But dude, you really need to wear a helmet to protect that formidable ingenuity between your ears!

[@captaingreenbush]

Beautiful work, I've got a 1941 Schwinn I've been wanting to stick a motor on, I was thinking of using one of the Chinese 2 stroke kits that are so readily available but after seeing this I think I need to rethink that and build an engine instead, the open crank design is badass! I think I'd rather mount mine in frame though and use a belt drive, and probably geared timing rather than a chain. I hope you did a video on the build, I'm going to look for it now, if you haven't you should, excellent work..

Good Job-but- Rainwater in the Piston?

[@hootmanwillie]

that must be hard on tyres but you can get special tyres that last longer, you are a genius to have made that amazing engine

[@robinhooodvsyou]

Actually, it`s the size of the "roller" that largely affects the wear rate of a tire, I once had (still have a video of it) a similarly built bike which had a 20 cc weed trimmer engine and a 25 mm roller, as a result I could really tell how much the tire was worn just by looking at it.

+grabir01 The little oiler on top of the crank pin - total loss I guess. He shows it towards the end of the video

[@rivaldilambadokoharahap1536]

awesome, so simple. how to lubricate piston and cam?

[@KiwiPowerNZ]

+Rivaldi Lambadoko Harahap I was thinking the same thing. The cam lobes will collect a lot of dust from the road back there and it will mix with the oil and make like a grinding paste on the cam lobes.

[@Sohave]

+Rivaldi Lambadoko Harahap I think it has a bearing like the one you would find on the crank of a steam engine and it would require similar attention.

[@Sohave]

+Rivaldi Lambadoko Harahap 7:43 there is an oil cup fixed to it.

[@petermalable]

+Rivaldi Lambadoko Harahap you mix the oil like 2 stroke

[@brucethehealer]

What a wonderful invention, however in the u.k it would need so much protection around it to comply with Health & Safety Regs it would not function...well done Robin!

[@thephilpott2194]

The mathematics of this are flawless. Every time VW barrels are used that's one more Beetle off the road.. Could you make a few using Citroen 2CV cylinders..? Please? The low compression has made this work- it is a rare engineering gift of being able to see things in 3D before you have finished designing them. well done.

[@robinhooodvsyou]

Thanks. I think citroen 2CV cars are pretty rare here in finland, so if I am to build any of these contraptions again I`ll probably stick to one of my VW cylinders. And, I suppose I have some kind of engineering "gift", my mild autism makes it very easy to design mechanical things in my mind.
