An often overlooked important difference between a radial engine and a rotary is the fuel and ignition systems. On a radial the carburetor feeds the cylinders as on any modern piston engine, with a intake ring, which is a manifold- and an intake valve. This isn't possible with a rotary engine because the carburetor would be spinning along with the cylinders. So a rotary engine has a specialized fuel inlet at the bottom of the cylinder which feeds the fuel air mix through the crankcase. Some rotary engines have only an exhaust valve such as the gnome Monosoupape aircraft engine, where fuel enters through a bottom port. All radials use an intake valve and an exhaust valve, a stationary carburetor and can be throttled. A rotary also has no throttle and its speed is controlled by either the load itself or an ignition cut out.
HI Dave cool explanation ...i was wondering how they dealt with the ignition on those rotary engines ...i understand that the noise of a world war one aircraft coming in to land was the cutting in and out of the ignition as there is no way to fine tune the fuel and i suppose a rotary engine would have to be two stroke ..but the spark eludes me
If the engine is rotating around a stationary crank then the fuel has to be delived via the crank and in the case of the rotaries shown here the exhaust exits from the same location - a form of 2 stroke engine, I think. The same goes for a special arrangement for sparks. If the engine stays still the fuel, sparks and exhaust can be delivered in a conventioal manner as in the 18 cylinder beauty shown at the end. Great video - thanks.
Bearing in mind its size and shape, placing a radial engine in the middle of the driven wheel would seem optimal. But why, in the first example, was it placed in the front wheel? This arrangement means that all piping must be flexible and electrical connections longer, as well as vastly increasing the mass to be turned, and massively increasing understeer and scrubbing on corners. Placing it inside the rear wheel would avoid all of these problems, and place the centre of mass further back. Any oversteer would be predictable but avoidable.
There is a electric motor for the front wheel of a bicycle now. While considering the application i had the same thoughts, albeit with a little less knowledge
Contrary to what one comment here says: not oversteer but understeer, which is the problem commonly seen in front engine front wheel drive cars but applies just as much to a motorcycle with front engine front wheel drive. Who knows, he might have just gotten autocorrected
Cj T I have ridden electric bicycles with motor in the front. For an ebike this works pretty well as long as the rider is aware of its limitations. My bike had enough torque to spin the front wheel (causing loss of balance) if the surface was wet or covered in dirt/gravel so I was always extremely gentle accelerating except on dry clean pavement. I also had a good front-rear weight balance due to electrc motor being in the front wheel and battery being above the rear wheel. With more torque, or if it were used mainly off pavement, I'd view the front wheel drive setup as pretty dangerous.
Doug... thats because like a V8 the powerstrokes are usually overlapping when cylinder is on its exhaust stroke another 1 or more are on the power stroke depending on how many cylinders..fighter pilots prefered them because if an inline V12 lost a cylinder it would shake itself to bits were as a corncob could loose a whole jug or 2 & still get you home.

Very interesting and fascinating! However, a slight correction is in order. The first two bikes shown with the engine in the front wheel... these are rotary engines, NOT radial. Very easy to tell the difference. In a radial engine, the cylinders are stationary and the pistons, eccentric crank, etc., move inside. In a spoke-type rotary engine, the crank and etc. are stationary and the cylinders rotate. This type of rotary engine was used in early bi- and tri-planes; a notable example is the Sopwith Camel. That last engine, the 18-cylinder radial, was quite fascinating! I have never seen a two-row radial engine that small before! Must be capable of rather high rpm. I'm willing to bet the timing is a royal you-know-wbat, though! Thank you for sharing. ☺👍
The Megola has a rotary engine, not a radial. They're very similar, but in rotary engines the pistons rotate around a stationary crankshaft, while a radial engine has fixed pistons and a rotating crankshaft. And a Wankel Rotary is something else altogether, it has no pistons and is the one used in the Mazda RX series.
As there was reports of a few radial engines powering motorcycles when the few were built as FWD could have been that rare when finding one today in original condition could be like the saying to find a bone needle in a haystack as the saying the radial engines were like the saying they were that rare when the saying the engines were like hen teeth.
Just FYI: The engines that are mounted in the wheels that spin. They are NOT radial engines. They are rotary engines. They came out before the radials and tho they look similar and sound almost the same but the Radial is a far superior engine. Nice little video even if it is miss labeled.

@@bredbeddledehautdesert4561 "ro·ta·ry en·gine noun an engine that produces rotary motion or that has a rotating part or parts, in particular. an aircraft engine with a fixed crankshaft around which cylinders and propeller rotate. *a Wankel engine.* As I said, the mait difference between the radial engines and the original "rotary" engines is how the were mounted. They were still radial, they just had the crankshaft locked so the entire engine spun. In other words, the different name was because of how the engine was used, not to any real difference in the engines themselves. Where as the Wankel is a true rotary.
Iariwoo When the Megola was built, few motorcycles had clutches. If you had to stop, you killed the engine. Keep in mind that there was very little traffic, few stops and no traffic lights at the time. Later versions did have a clutch.
Remember that rotary engines, i.e., engines that rotate ABOUT the crank shaft (NOT radial or inline engines that remain stationary while the crankshaft rotates as in modern engines), were the principal engine employed in many First World War military aircraft used by both sides. So, in the years after the war, these engines were plentiful (and likely cheap) and well-understood. They were lighter and ran cooler that radial and inline engines. It's a wonderfully creative idea.
If the cylinders move around a stationary crankshaft, it's a rotary, not a radial. Wankels aren't the first engines to be called rotary engines. On radial engines, the cylinders are fixed and the crankshaft rotates
That effected exists whether it is driven or not, as long as it's spinning. This effect actually helps bike stability. Though the extra weight would indeed affect how steering feels.
Well kind of, harleys do have single pin cranks but they utilize a knife and fork rod configuration vs the master/slave rod setup found in radials. And boy oh boy do i love my harley garbage! 😁
@@BagpipekilR Right, they are basically two cylinders cut out of a radial. Don't get me wrong, I respect all bikes, Im just not a fan of certian brands and types. I did like the Pro Street Breakout they made, that was a very cool looking bike. In my eyes were all brothers of the road.
When the Megola was made, almost all radial engines were rotary, ie rotating cylinders and stationary crank. Also, it would be difficult to package a radial engine not inside the wheel, so it just follows....
Radial engine was an utter failure ... If engine is placed on front tire .... It is very hard for the driver to move handle because of shaking and weight and torque produced
no the handle was not the problem, but the speed controll was close impossible and if the motorcycle stops did the engine stops...the all firt rotary engined motorcycle was the 1893 Felix Millet (5 cylinder)

an aircraft engine with a fixed crankshaft around which cylinders and propeller rotate.
*a Wankel engine.*
As I said, the mait difference between the radial engines and the original "rotary" engines is how the were mounted. They were still radial, they just had the crankshaft locked so the entire engine spun. In other words, the different name was because of how the engine was used, not to any real difference in the engines themselves.
Where as the Wankel is a true rotary.
Even for their size they sound badass.
The first motorcycle can go straight, but can not turn right or left?
Amazing bike legendery....good
So how do you pull away on that fist bike, and what do you do at traffic lights? It doesn't appear to have a clutch
Iariwoo
When the Megola was built, few motorcycles had clutches. If you had to stop, you killed the engine. Keep in mind that there was very little traffic, few stops and no traffic lights at the time. Later versions did have a clutch.
The Megola iser manual says you should "orbit" at a stop sign.
So what does that mean!!? lift the wheel off the ground, or ride around in circles!! :D
If you look closely it looks like theirs a kick stand in the front so I'd assume you lift the front tire
Simple: you don't stop at traffic lights! just keep going until you reach your destination
That's some true engineering right there
Beautiful 🇧🇩
Remember that rotary engines, i.e., engines that rotate ABOUT the crank shaft (NOT radial or inline engines that remain stationary while the crankshaft rotates as in modern engines), were the principal engine employed in many First World War military aircraft used by both sides. So, in the years after the war, these engines were plentiful (and likely cheap) and well-understood. They were lighter and ran cooler that radial and inline engines. It's a wonderfully creative idea.
If the cylinders move around a stationary crankshaft, it's a rotary, not a radial. Wankels aren't the first engines to be called rotary engines.
On radial engines, the cylinders are fixed and the crankshaft rotates

I wonder if the bike fights you when you try to turn. Wouldn’t this engine create a gyroscopic condition?
Good question.
That effected exists whether it is driven or not, as long as it's spinning. This effect actually helps bike stability. Though the extra weight would indeed affect how steering feels.
If is attached then only wind resistance, if it is balanced
The pistons have reciprocating motion, if you clock them then you'll cancell all the gyroscopic stability which makes the bike easier to handle
The only gain of gyroscopic resistance would be resulting because of the weight of the engine which creates a more important inertia
Fantastic ! 👍🏻

In the U.S. there were a few motorcycles built using full sized radial engines out of ww2 airplanes. One of them was called Radial Hell.
Me:Wankel eingine or this eingine?
Shrek meme:good question
Wow this is awesome.
I have a question. Can we control the speed of the bike?
No, the bike decides what speed it wants to go
Harley Davidson's are a radial engine ...only 2 cyl worth of garbage..but it's still a radial engine. The rods are on the same journal/pin.
Well kind of, harleys do have single pin cranks but they utilize a knife and fork rod configuration vs the master/slave rod setup found in radials. And boy oh boy do i love my harley garbage! 😁
@@BagpipekilR Right, they are basically two cylinders cut out of a radial. Don't get me wrong, I respect all bikes, Im just not a fan of certian brands and types. I did like the Pro Street Breakout they made, that was a very cool looking bike. In my eyes were all brothers of the road.
Não senhor, o motor Harley Davidson tem vibrequins, é o único motor com vibrequins alinhados, mas o motor radial não tem vibrequins.
Best sounding engines ever made.
I think the first bike would actually be referred to as a rotary motorcycle even though it's a radial engine. not trying to start an argument here.
Correct. Now maybe we can answer why Mr. Megola thought this was a good idea.
It's a rotary radial engine as used in many WW1 aircraft.
twe ak
Those airplanes used large displacement rotary radials designed for aircraft use by various manufacturers, they didn't use Megola's engine.
Because he was a crazy inventor who liked spectacular and unique machines maybe.
When the Megola was made, almost all radial engines were rotary, ie rotating cylinders and stationary crank. Also, it would be difficult to package a radial engine not inside the wheel, so it just follows....
Really good thank you for the share
The Verdel is fake, its not 1912 , more like 2000.. made by a chap near me in Gisburn near Clitheroe Lancashire
Michael Schofield so a reproduction?
No, it is a total fabrication. There was no Verdel Rotary built in 1912, or any other year
@@2bitmarketanarchist337 No not repro, it was the imagination of a talented engineer, he never wanted it to be portrayed as old
@@michaelschofield1537 Ah
Awesome video love it thanks
the first bike has a rotary engine not a radial engine
first one was a rotary. Rotary engines have fixed crankshafts, the load is connected to the engine which spins with it.
What is a "radial engine Ever Built"?
Well that brings up more questions than answers.
Radial engine was an utter failure ... If engine is placed on front tire .... It is very hard for the driver to move handle because of shaking and weight and torque produced
no the handle was not the problem, but the speed controll was close impossible and if the motorcycle stops did the engine stops...the all firt rotary engined motorcycle was the 1893 Felix Millet (5 cylinder)
Wow pretty cool I love the sound of them especially the 18 cylinder
my father has a NEW HUDSON 1914
Thank you for sharing this, something I've never seen
Hi and i have a mate with the brough superior radial 3 if your interested
wow
I gotta admit, a rotary engine in the wheel hub is pretty darn ingenious - but how do you idle and keep the engine running?
can i have the intro music please? Thanks :)
