Struggled with where to post this so pointless drivel seemed appropriate. Soz if a repost. Get over it.
My small brain is struggling with the dynamics of this layout.

Looks like the rear might be castor-ish, with the front steered like a hub center steered bike, and the middle wheel being like the normal swing-arm. Reckon it'd have to be tested in the white heat of racing to get any traction (swidt) as an idea.

How would one do wheelies?

Moot point for me. Can't pop it up for shit.

What's the point? Is it two wheel drive? better braking?

It will still fall over! and tyre changes have just got significantly more expensive.

The design will limit engine configuration.

Again - what's the point?

I like both wheels on the ground... but so many don't and I thought I'd ask the question.

What could it possibly do that the Piaggio MP3 and its siblings can't?

Probably designed by the tyre industry to sell more product!:blink:

Well then this is the bike for you perhaps? (although I just committed the first faux par by calling it a bike, which implies two). Anyways with a hydralic ram arrangement you could pop a wheelie & still keep two wheels on the ground. Result.

A guy once showed up at the Brass Monkey rally with an inline three wheeler Dirt bike (Home built). Both rear wheels were driven. He had no issues ... and tried hard to get it bogged. And failed. He rode over the roughest bit of public road in Otago (the Old Dunstan road) in the shittiest of weather. The road was actually closed due to snow.

He rode home to Dunedin the same route.

Fall over when stationary.

There are plenty of US Hyabusa and Z14 drag bikes that have a driven trailer wheel - for 'traxtion' when you give it the gas, man.

Just got round to viewing now I'm home. Good mockup, but fails in some clear areas of packaging. Like weight of engine too high. Frame rigidity questionable, suspension of middle wheel dire, ( virtually no travel and packaging of linkage and shock troublesome ). 10l gas maybe. No airbox. Where's the clutch and gearbox again?

still kinda cool exercise
