It’s not a bicycle you are looking at. The Hoverbike is a motorcycle-like ultralight aircraft that’s powered by a flat twin 4-stroke of 1170 cc with a 12:1 compression ratio that you kind of ride like a motorcycle to go up (estimated 10,000 ft) then at a speed of (?) to do what? Inventor’s suggestion: Aerial Cattle mustering, Search and Rescue, Aerial Survey, Wildlife and Parks Observation, Powerine Inspection, Film Shooting, Impressing your friends, etc.
You lift off by increasing thrust via a throttle grip exactly the same as the throttle on a motorcycle. To fly forward you must both increase thrust and deflect air from the front control vanes by twisting the left handle grip to accelerate forward or twisting back to go backwards. Turning right & left requires to push down the handlebars down on the side you wish to turn. Limited ground testing done thus far confirms that the Hoverbike performs exactly as predicted. You can test ride it if you travel to Sidney, Australia. Price to be announced after a rich investor is found… Hoverbike.
