Another progress shot. Not any radical changes from the initial shape. Have smoothed out some hard corners, added stabilizing fins and changed the cockpit canopy.

This is awesome but...

... it would suck if the monocycle crashed like McLean's V-8 back in 2007 link, my condolences to him, his family and friends. McLean's been designing and creating his monocycles for years... he's not the first to create the monocycle but, he is the first man to attain the Land Speed record on one wheel @ 53 miles per hour. You might want to take a look at his YouTube Channel for further inspiration (McLean's YouTube Channel). His Drag Wheel is bad ass but, if you watch his opening video... it explains a lot of information. Stability is probably one of the biggest problems you'll have with a monocycle, as there's only ONE point the vehicle touches ground and having the wheel by itself isn't enough to keep it upright. You might want to add larger tail fins that compliment the design of your monocycle. Based on McLean's response to my question about his creations 3 years ago, a monocycle works almost in the same manner as a recreational aircraft, minus the wings and propeller.

Can-AM's BRP Embrio (link of vehicle) utilizes a couple unique features. A set of smaller wheels in front of the main wheel help to increase longitudinal stability. When the vehicle speed reaches 20 km/h the wheel-set retracts. Another unique feature in the Embrio is it's on-board gyroscope, even without the smaller wheels touching the ground in front, the Embrio would be stable when motionless because of the gyroscope. The engine mechanics of the Embrio are impossible to fit in such a small design, I did my high school senior essay on Hydrogen Vehicles in 2008... while my theme wasn't as exciting as my other graduating class members it does shed light into the world of hydrogen vehicles as an alternative and renewable fuel source vehicle. Sorry I went into a tangent. ^~^;

I'm not sure how far you thought about the mechanics of a concept like this but if you would like to talk more about it, I wouldn't mind sharing with you what I know. :meow:

Hi mate, yes please share! I am familiar with the McLean V8 and his most unfortunate crash. It was wobble that made him crash I believe, and it looked really quite nasty. I hope he survived. It's easy to say in hindsight, but McLeans bike was an accident waiting to happen, and if it was me building that contraption I would've built a spherical  roll cage around it with just enough clearance at the ground to lean without scraping. That and a five point harness in a racing seat. That way, when he did crash he would litterally just roll to a stop. The inherent problem with his setup was always balance. His bike relied on gravity/weight of the V8 and human body alone. Problem was, that that is never going to be enough. The engine produces a lot of torque so accelleration has to be real slow. Same goes for braking. The torque allready in the spinning wheel tries to counter the force of the brakes, which makes driver and engine want to climb the rim when he brakes too hard. This is probably what led to the crash, bechause as all the weight from the engine and body climbed the rim it off set the balance of the bike and started the wobble. when he let go of the brakes all the weight "fell" back down and increased the wobble to catastrophic results.
 I have thought about that a great deal. This monocycle will have a serious gyro setup to avoid those kind of problems. I don't know if you've seen this www.youtube.com/watch?v=VkvvsR… This bike uses a gyro setup and it's not possible to tip it over, it just bounces back up.  I figure we're in the dawn of gyro controlled vehicles, and... 
I'm putting a nuclear fusion power plant, jet turbine and afterburners in my bike so ultra realism is pretty much out the window from the get-go hehehe. The idea here is to make a monoracer from the 22nd century that is going to be used in 1000mph endurance races on tracks at various places on the solar system.. It's science fiction (read bs)
But anyway, back to the gyros. This bike will have four of them, adjustable in three axis, so the bike will be able to accellerate, decellerate, lean and turn with gyro control alone. This system is in a loop with esp, road surface sensors and driver input etc.  Now, bechause these gyros have to be within the rim, together with the reactor, turbine, generator  and linear el-mag drives for the wheel, I opted for an offset, external cockpit. I also stretched that out a bit since the bike is asymmertical. The idea is that the huge intake on the other side will create more drag, therfore the cockpit has to stick out more since it's streamlining will create less drag. The onboard turbine is going to create a lot of torque, but it's going to have counterrotating impellers to balance itself out and not f**k with the gyros.
 This is the theory anyways, but what the hell  I'm only gunning for plausibility and coolness since this contraption along with all my other ones will never be built, hehehe.

How does it stand up when it isn't rolling?

Hi mate, thanks for the question . It's held upright by a series of computer controlled, 3axis moveable gyros. Should make it rock steady. It's ment to attain speeds of 1000mp/h so it needs to handle well, hehehe.
