Last month we covered the launch of an interesting Kickstarter project that aimed to jump-start sales of a drone version of a fully-functional hover bike. The quadcopter drone acts as a proof of concept for the full-sized manned vehicle, with proceeds from the crowdfunding effort intended to fuel the continued development of the final vehicle. Gizmag visited the Malloy Aeronautics workshop in the UK to take a closer look at the Hoverbike project.

With more than a week remaining before the Kickstarter campaign concludes, its funding goal has been exceeded and development is moving forward at pace. Though the manned Hoverbike is what tends to garner the most attention, the one third scale drones are actually the focus of the Kickstarter effort.

The quadcopter drone can be accompanied by an anthropomorphic, 3D-printed figure known as Cyborg Buster, which features a space to fit a GoPro camera in its head. The drone is capable of following the pilot, following a predetermined flight path, and even has the ability to perform automatic take-off and landing maneuvers.

At this stage, there are three versions of the Hoverbike. The original two rotor manned vehicle, the quadcopter drone, and the still-in-development second prototype Hoverbike.

Thanks to the crowdfunding campaign, we’ve seen quite a lot of the drone, but the full-sized vehicle, in its MK2 state, has remained something of a mystery. Though we’re still a few months out from seeing the finished prototype, the full-sized Hoverbike is already an imposing sight. The quadrotor frame is similar to the drones offered on Kickstarter, but decidedly more angular, constructed from a combination of carbon sheet and aircraft-grade aluminum.

The design of the manned vehicle is cleverly thought out and features a number of interesting design points, such as adjustable weighting in the central section to ensure correct balancing regardless of pilot physique, a self-cutting rotor channel, and offset rotor placement.

In its current, rotor-less state, the inside of the circular, protective blade housing is filled with UV-stabilized polycarbonate (as pictured below). Once the rotors are fitted, they’ll cut through the material, creating a channel that reduces the clearance between the propeller top and duct wall.

The offset design of the four rotors allows the protective frame around one of the blades to be used as a mounting for the other, meaning that the revised vehicle can keep its narrow profile, making it practical for negotiating difficult terrain.

Though the act of designing and creating a fully functional hover bike may seem technologically Herculean, there’s no practical barrier to making it happen, at least not with the quadrotor design Chris Malloy and his team are working on with the Hoverbike. While public skepticism may be a significant barrier, the real challenge is bringing together existing technology, while making the vehicle safe, practical and economically viable.

The move from a dual to quad rotor setup is all about stability. The original Hoverbike design was certainly eye-catching, but it suffered from significant practical problems – namely, that if it were to reach a certain angle in a turn, it would become difficult for the pilot to right the vehicle. This is no longer an issue with the quadcopter design, with the varying thrust of the four rotors affording the vehicle significant stability.

If you find yourself talking to someone about a project such as this, one paramount area of concern that quickly arises is safety, and understandably so. Despite its name, the Hoverbike is not a hovercraft. It will travel up to altitudes in the thousands of feet, as well as achieve significant forward momentum.

One key piece of the puzzle here, and something that should assuage many safety concerns, is that the manned Hoverbike will be equipped with autopilot capabilities, just like the drone version. This means that though the vehicle can be piloted, a significant margin of human error can be removed from the equation.

The autopilot function also provides the option to remotely control the craft, making it well suited to supply drops, search and rescue operations over difficult terrain, and a whole host of other applications. From mountain rescue scenarios to Red Bull Air Race-esque sports applications, the list of potential uses for the vehicle seems practically endless.

With the Kickstarter project having already exceeded its funding goal, and with murmurs of outside funding, the project is moving full steam ahead. Once the crowdfunding effort concludes on August 31, the team will continue to sell the quadcoptor drones, and plans to test the manned-vehicle within a few months.

If you’re interested in being part of the effort, then you can head over to the project’s Kickstarter page. For more images of the both the first and second prototypes of the Hoverbikes, and the quadcopter drone, head to the gallery.

where is the engine compartment? if its not UNDER , it will suffer the same consequences as the "millieum Jet". good luck flying, seems like a good project.

This is where all this is heading. Fantastic job. You could send a person on a flight and control it from the ground. Can't wait to see future follow ups.


Will it include a parachute for both rider, & vehicle?

Bob Flint

@Bob, just the vehicle, the rider went through the propellers causing the crash

Bill Bennett

surely it would make more sense to sit under the thing, not on it?


I assume that it is completely 'fly-by-wire' with stability maintenance built into the flight algorithm. If so then the only danger is something falling off the rider into the fans, such as a video camera, or a bird strike. Whatever it is would dramatically increase the much vaunted clearances between the fans and their housings! Unfortunately, working on the 'if it can happen, it will happen' principle, this eventuality will have to be catered for in the design This will both add weight and impede the airflow somewhat, probably to an unacceptable level, assuming that it is even possible, of course.

As for a parachute, well, it would need to be explosively deployed to get it through the intake airflow and clear of the rotors, three of which might not only still be functioning, but also at full throttle in an attempt to maintain stability.

I think Mr Malloy would find development of the drone version far more lucrative than continuing with the uphill battle to get the manned version operational, especially seeing just how popular drones are today, particularly with the military. Let's face it, one death because of a loose flight map falling into one of the rotors and all the hard work would come to naught in an instant with a CAA or NTSB grounding. That would a tragedy for the pilot and a shame for the venture.

This will need radar and computer to pilot the swarm.

Art Toegemann

This is stuff you dream about when you are a kid, but then, you grow up and relies it's a pipe dream, and probably dangerous as H-E double toothpicks

Jay Finke

Love to see developed & then mass produced.

And other than be a toy for the 1% what real function could something like this have? None!

Nelson Chick

When I was younger, I read comic books, one of which was named total war. They had vehicles like these but were used as jeep or HMMVV type utility vehicles for scouting, quick deployment, special teams and ambushes. A that time not everything was air-mobile, but it did not require a special license like a helicopter does.

On these demos I believe they are all electric motor at the hub of each fan with a central power supply, and either quick change or quick charge. t should also be easy to put some rare earth batteries in the rotor as an alternate charge source, producing a trickle charge with every revolution of the fan.

The technology is not far off that could reduce the rotational friction of the fan and motor to near zero.

If it was wider it would be more stable. "...meaning that the revised vehicle can keep its narrow profile, making it practical for negotiating difficult terrain." Difficult terrain? Just fly over it.


Would you please, please, PLEASE, stop calling anything with 3 or more propellers a drone!?

Hobbyists are having enough troubles with the FAA shutting everything down without every ignorant Tom, Dick, and Harry putting the word drone on anything that flies.

The model show is not autonomous, does not carry weapons or spy cameras, nor does it live in a hive to serve a queen!


After such a plethora of fictional vehicles with enclosed rotors have been popularized in recent years, seemed something similar might finally be attempted. Very, very cool, esp with the 2nd prototypes quad-based stability.

My two cents would be, would it be practical or possible to even further enclose the rotors with a fine grid composed of very light, strong and aerodynamic filaments criss-crossing the top intake prevent any objects larger than a few inches from getting accidentally passed through?


This is basically modified helicopter tech that is old.It makes cute gadgets but the real advance in tech will be when mankind learns how to manipulate electromagnetism. When that happens props and jet engines and even photon thrust engines will be jettisoned and intergalactic travel will greatly benefit and the "speed of light theory" that puts a speed limit on space travel speed will no longer apply with a force field protecting the craft. You think that this is science fiction well go ahead it's you right to think whatever you want but after the singularity occurs I imagine that it won't be long before the problem is solved.


I think it's pretty cool. Personally, I'd rather not fly one, but I'm not found of having my feet off the ground.

@Mel - This falls into the experimental category as far as aviation authorities are concerned. The whole grounding thing is applied to production airframes and variants. Safety applies everywhere, so dropping something is pilot negligence and would result in some type of prosecution.
