The design of the motorcycle was developed by Tamas Jakus, giving the name to the concept Jakuza Atlantico.

Liquid Cooled?

 

edit:  NOPE!!  Built on a FatBoy framework.  Must be a big oil cooler to make up for the lack of air flow.

"

The Megola motorcycle was designed by Fritz Cockerell in 1920, it’s powered by a 5-cylinder radial engine mounted inside the spokes of the front wheel. The are a few benefits to this layout and a couple of drawbacks, on the positive side there is very little power lost to mechanical drag and the engine’s simplicity means that it’s quite reliable.

On the negative side, there was no clutch, gearbox or neutral – so whenever the bike need to come to a halt the engine had to be turned off. In 1920 when traffic lights were a rarity this wouldn’t have been nearly as problematic as it would be now."

Sounds like new cars today.

By definition it's a rotary engine

 

Quote

A rotary engine is essentially a standard Otto cycle engine, with cylinders arranged radially around a central crankshaft just like a conventional radial engine, but instead of having a fixed cylinder block with rotating crankshaft, the crankshaft remains stationary and the entire cylinder block rotates around it. In the most common form, the crankshaft was fixed solidly to the airframe, and the propeller was simply bolted to the front of the crankcase.

 

Rotary engines utilize a total Loss lubrication system as the centrifugal force of the rotating cylinders prevented recovering the oil. 

 

Radial Engines have fixed cylinders and a rotating crankshaft. The lubrication system is a closed system as most of the oil can be recovered and recirculated through the system.

Some brilliant geometry on that wheel. 


A totally exaggerated rendition of the old “SPRINGER” suspension!

 

It works, but that example is pretty much ridiculous!  You’d be hard pressed to make right turns in downtown traffic!!  That hydraulic drum brake ain’t much either!!

I posted that long chopper to see reactions. 
 

Me personally, I cannot imagine a more useless vehicle. 
-You’d have to figure out what gas stations to use based on access and egress. 
-Riding into and around in some small towns would be ridiculously awkward.

-Going into and navigating the average parking lot would be a chore.

-If those foot pegs are solidly mounted it looks like your max lean would be about 30°

-It looks like a hard tail. That right there puts it into the “Suck” category.

@Blackwater 53393 Was referring to that particular rocker, not the type of front end as a whole.Screenshot_20241008-000651_DuckDuckGo.jpg.ed9f5f73caa76aba406519761a43c60a.jpg  Yes, it will work, horribly.


you’re right about the rockers, no doubt, but as long as those forks are you practically don’t need the rockers.  That is, until the whole thing breaks from stress! <_< :rolleyes:

If that bird was a little bigger, there’d be no need for other transportation!!  :lol:

I rode a bike twice wearing shorts.
The first time I got a piece of what I am pretty sure was a 2 1/2” long piece of wire from a wire wheel was stuck in my right shin. 1” of it was sticking out. The rest was in my leg. I think the lady in the car next to me at the red light nearly feinted when I pulled it out and was looking at it. I heard a funny noise (I also wasn’t wearing a helmet) and when I looked over she was staring at me and was a lovely shade of gray. :lol:
The second time I was washing my bike on a sunny day. All I was wearing was a pair of shorts. After I dried it all off and put tire shine on the rubber and polished the chrome I wanted to take a spin around the block to blow any water out of the nooks and crannies.   
As I rounding the second turn my rearend slid (remember the tire shine?) and I instinctively put my bare right foot down to stabilize the bike. I folded my little toe backwards against the right side of my foot. Boy, did that hurt. I somehow stopped the bike and hopped over and sat on the curb. 
A lady friend / coworker of my wife’s happened to live right there and she saw what I did. She ran over, looked at my foot, then reached down and snapped my little toe back into position. I never made a peep as all the air left my body and for a brief time my body wasn’t letting any air back in either. 
That hurt like crazy but I did get back on the bike and ride it home. 
 

It’s my opinion that my guardian angel gave me a warning and I didn’t heed it so I got an even more painful warning the second time. 
I haven’t ridden a bike since without footwear or pants. In those days I wore jeans. These days I wear cargo pants. For a time I did wear sneakers on my bike and decided that was stupid. Since 1990 I have worn boots on my bikes.

That hurt just reading about it.

Back in the late 90s while driving on the 14 in southern Cal, I saw a guy in a crotch rocket wearing flip flops, speedos, and a full face helmet that cost north of $1000.

 

Thought to myself that when he had a wreck they would be able to id the body as his head would survive unscathed.

The worst thing I have seen in this regard was a guy and a girl wiped out on a bike in Palm Springs during Spring Break of ‘83. No helmets. They both had on swimsuits. They were wearing sneakers. 
She had something like this on.

They passed my wife and I on a 2 lane road heading out of town. We were doing around 50. They were probably doing 80 when they went around us. 
I remember saying to my wife “They better watch it on these roads. Lots of sand to make traction exciting on a bike.” Or something like that. 
A couple of minutes later we came upon several cars stopped in the road. Apparently there was a car crash. To avoid the car crash the guy operating the bike laid on the brakes, slid and lost control. The bike went down and the guy and the girl slid on the rough asphalt. 
He didn’t slide as far as he made contact with the wheel of a car. He was out but alive. She was about 60-70 feet further away. She had severe road rash from head to toe. Part of her left buttock was missing. The back of her head looked scalped. Her top was missing. She was conscious and in lots of pain. 
My wife ran back to our car to get our trunk blanket. (We always have emergency supplies in our vehicle.)

The ambulances and police showed up and the couple was  taken to the hospital. 
 

This was in the days when you could call a hospital and get info on a patient. My wife called and found out that the girl had no broken bones but would undergo lots of surgery for skin and muscle loss. The guy had less road rash but broke both legs. We found out later from the police that they were both college students that had just met in a bar that day.
