That does sound like a WWI/WWII plane. the engine being a radial is one reason and it's the same concept as the knome engines from the first world war planes except they used cylinder deactivation to control engine speed which explains the sound of an engine surging and spluttering in flight.
Is it possible to disengage the drive (clutch / Kupplung), or does the engine stall if the motorcycle stops ? That would make it difficult to drive..... It's OK, I got my answer on another video, not possible to disengage engine/drive.

Is this engine able to idle while the wheel is in standstill? I'm just asking because at the beginning we don't see how the rider started rolling and at the turnaround on the parking place he did not stopped at the Stop sign 🤔😅
When you come to a stop (like at an intersection) the engine stops too. When you want to start moving, you move forward and re-start ignition. There is no clutch.
This is sitting in the motorcycle museum in Solvang CA if you're ever in the area it's definitely worth the $10 admission. Showing is by appointment only.
haha no gears, no clutch, a mess to start up but the tradeoff was that you got front wheel drive on a bike. it is as fascinating as it is lame. never thought that such a beast could exist
Ok guys... so how does it work? Carburetor stays stationary and the intake runnes get aligned to it as it spins? Do the cylinders fire as they reach the same spot? So many questions...
Like the fighter planes from the great war with rotary engines. That technique had been state of the art these days. Google rotary engine in wikepedia and you will see how it worked thousands of times in the fighter planes of WW1 and in this motorcycle.
It messes with your brain to think of the crankshaft as the axle and of it being stationary while the rest of the engine spins around it and takes the wheel with it.
So fuel delivery on these "rotary engines" was a problem. It was fed through a hollow crankshaft into the crankcase which doubled as an intake manifold. There were identical tubes running from the crankcase up to the intake of each cylinder. Apparantly, changing the engine throttle takes genius level artistry.
@@7MPhonemicEnglish Throttling was only a significant problem on the "monosoupape" (one valve) engines. Those had a transfer port like a two-stroke. They opened the exhaust early so that when the piston is at BDC the cylinder is already at ambient pressure and no exhaust gas goes back into the transfer port (that of course is some lost efficiency already), then they push out the remaining gas, suck in air through the SAME valve (and cooling it that way), close it early so that there is vacuum in they cylinder which then sucks the very rich mixture from the crankcase through the transfer port into the cylinder, where it mixes with the pure air to get the correct mixture. en.wikipedia.org/wiki/Gnome_Monosoupape That of course only works at one throttle setting. Later rotarys (like the one in the megola) had 2 valves and a standard carburetor.
In the 1920ies they still had belt driven and no gear box motorcycles. These had the same "problems". So that had been no problem in these days. Do not judge from todays perspective.
Da sieht man, wie einfallsreich die Fahrzeugtechniker vor über hundert Jahren schon waren. Heutige Konstrukteure könnten sich durchaus etwas abschauen. Ein eindrucksvolles Gerät, wenngleich in der Optik und Ausführung nicht ganz nach meinem Geschmack. :)
The real doktorbimmer Oops. From wikipedia: Rotary and radial engines look strikingly similar when they are not running and can easily be confused, since both have cylinders arranged radially around a central crankshaft. Unlike the rotary engine, however, radial engines use a conventional rotating crankshaft in a fixed engine block. So the frontaxle of the Megola is also the crankshaft. Does that make this a radial or a rotary engine? I'm getting a bit confused here since with the term rotary engine I imagine the Wankel engine like Mazda uses and that looks completely different from this. However when I google "rotary engine" I also get pic's of engines that look like the starengine that's in the Megola ???? So with the cranckshaft staying in place when the engine is running and shutting down the completely when the vehicle stops makes this a rotary right?
OpaSann0 Yes, some Rotary engines do have reciprocating cylinders in a "Radial" arrangement, but not all do. Rotary engines do not have a "Conventional Layout" which includes a rotating mainshaft or crankshaft and flywheel. Rotary engines spin concentrically on a "AXLE" or other fixed, non-rotating hub. The entire engines mass "Rotates" on its axis Invented by Felix Millet, the Rotary layout was also used by Felix Wankel for his "Orbiting Piston" Supercharger and a failed engine prototype design called the DKM-54 The later Wankel KKM-57(Orbiting Piston Motor, not designed by Wankel himself) discarded the Rotary layout in favor of a Conventional Non-rotary layout used by many manufacturers including Mazda...

Yes it's a 5cylinder rotary plane engine of BMW. They have built plane engines in Eisenach and it's a Wankel engine and good racing motocycle 14 HP 640cc 143km/h in the 30s.
Our great-grandfathers were crazy!
It's awesome to see these crazy ideas that companies had in the past
Well, at least the engine will never overheat. xD
Please do a video on how you start riding this Megola. Thanks!

😇
Toll, ich freue mich das Windgesicht im Café gestern getroffen zu haben. Sehr netter Mensch. Danke und viel Freude am Gespann, sowie der Megola.
Well, so much for doin' wheelies.
First version had engine in rear wheel
It even sounds like an Old Biplane !
Yes :))))
jackpontiac52 Because it is roughly the same engine design.
Correct !
Duh?😆
@@Call_Me_The_Storyteller Do you get out much?
This should have been made with an engine in both the front and rear wheels.
It would be AWD bike instead of FWD & RWD bike
Здорово,что такие аппараты ещё живут!
Love it , Great machine Love the handlebars
Oh my goodness! I need one of these in my life!
Fantastic.. time machine............. Bravo...! Riding position appears comfortable .. well done indeed.. indeed.
Dangerous and most cool thing I have seen.
Some very different engineering and solutions here. Great video. It sure is a great experience riding it.

technically this is a rotary engine, (by this I don't mean a wankel engine with the triangle).
Is it possible to disengage the drive (clutch / Kupplung), or does the engine stall if the motorcycle stops ? That would make it difficult to drive.....
It's OK, I got my answer on another video, not possible to disengage engine/drive.
once you stop, thwe engine stops too...
It doesn't have either a gearbox nor clutch. en.m.wikipedia.org/wiki/Megola
Just amazing!!!
Totally impractical bike, but.. but... what a sound it makes...wooow
Thanks for saving this for the future by video.

how do you start off or put the kickstand down?... the wheel is already moving. I NEED TO KNOW, i am so confused.
Kick stand only to warm-up the engine. To ride you push start it.
When you come to a stop (like at an intersection) the engine stops too. When you want to start moving, you move forward and re-start ignition. There is no clutch.
they don't show you putting that wheel down because its ridiculously dangerous…that is by far the scariest and most clever motorcycle i've ever seen.
You push start the bike, the stand is only for warm-up or tuning

What the hell happens if the traffic light shows red ?
Gun it lol

There is no stopping! Choose death beforehand.
Sounds like a fighter air craft from WW1. Prima!!!
that was awesome motorbike!
Why is it front wheel drive? Seems like more of a hassle to make than rear wheel drive
I love that grand pa is nuber 1 .
how do you stop does it have a clutch of some sort?
Johnny Pasillas no clutch, the engine stops!
HOW DOES IT IT GET FUEL !!!!!!!
NICE !!!!
how is the clutch of this motorcycle?
Ich liebe Umlauf Motoren bei Flugzeugen ganz besonders
That must be incredibly stable with the gyroscopic forces of the engine
Which also means difficult cornering. Harley may want to adopt this principle.
Awesome!
I wonder why they just didn’t do it to the back wheel.?
Not that that would solve the problem of stopping …!
comme lavion !
Nummernschild? Bekommt man heute für die Megola eine Zulassung?
How can such a weird bike look so comfy to ride?
Amazing bike
cool
And how does he stop???🤔🤔🤔
toll das man durch den heldenhaften Kameramann, der das Mikro genau in den WInd hält nichts von dem Sound hört ohne Ohrenkrebs zu kriegen
how does it work on stop and go traffic, like in the city?
Very poor, the engine does not disengage. You can only shut it off.
Designed primarily as a racing bike, no stop lights back in those days.. not many cars on the roads either.
The last thing I want to have is a front wheel drive motorcycle😂
Awesome machine
i like this bike
❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
Incredible
Engine is IN the wheel, yes its crazy nowdays o0
He didn't stop at the stop sign.
Unglaublich drei Daumen hoch!
And.... how do you stop?
gibt's ne Kupplung um anzuhalten wo dann die Achse durchdreht oder Wie?
Nein, es ist ein direkt Antrieb.
Der Motor geht beim anhalten also folglich aus.
@@greenfox9413 na das ist im heutigen Verkehr sehr schlecht
Preciosidad
this optimizes the idea of a mad german.
☺☺👍👍👍👍👍
FWD scooter in 1921! And with wich engine!
Front-wheel drive, in a motorcycle, in the early 1920s.
How do I Stop with this bike? The engine runs instantly.
kill switch- apply brakes or coast to a stop.
How much?
Maxl auf den weg zur schule be like
Absolut!..
Wie funktioniert das mit der Kupplung?
Ganz einfach, das Ding hat keine. Anhalten heißt Motor aus.
the old gnome has balls !
How does the clutch work?
There is no clutch, or transmission, if you stop the bike dies.
Is this bike a kind of Tamagotchi?
I want to know how you get it moving from a dead stop?
SAFECE MENGOLA YAZIŞMITŞIM.
No, the Engine stops!
In the 1920ies they still had belt driven and no gear box motorcycles. These had the same "problems". So that had been no problem in these days. Do not judge from todays perspective.
I you have to stop is it now a running start again and then jump on
Same as a bicycle. The rider on a bicycle does not pedal when he's stationary. In the 1920s motorcycle riders were real men.
Unbelievable
A SOUND OF A PLANE LOL
