ROADMAP

Follow us on our journey to change transportation.

PROTOBIKE 1 'BEATRICE' (2018)

Named Beatrice, Protobike 1 is the first, most basic prototype we had constructed. Professionally machined and completed in November 2018, it was designed to test several very fundamental principles of how our end-goal systems may work. Preceded by six months of effort, the testing that Beatrice allowed us to engage in verified that:

  • Elimination of rotors reduces barriers to adoption and creates a safer vehicle

  • Removal of ground friction has an unquestionable effect on efficiency

  • Our Hoverbike can be built to the same size/scale as a motorcycle

  • There exists room for wheel well hydraulics and engines after removal of the ICE Column and replacement with an electric drivetrain

  • Weight targets could be hit with core systems integrated, with a significantly lower dry weight

  • There is a high level of confidence maintained in riders seated on a flying vehicle

  • The hoverbike's more 'aggressive' seating position is comfortable

  • Rider reactions are overwhelmingly positive and optimistic

  • ...among other discoveries!

PROTOBIKE 2 'KIRBY' (2020)

Manned Prototype Flight Vehicle currently under development

After completing Protobike 1, we have confirmed the most fundamental engineering questions and gained a more thorough understanding of the practical design of our technology. The next step is to advance towards mass-market through a series of prototype vehicles. For this Protobike 2, we plan to integrate an electric drivetrain, high-power flight engines, flight control, hydraulics, and electronics among other components such as fairings (finally!). Designed for professional applications, Kirby is a high-power adaptation of our platform and will produce the most generous performance and cargo characteristics. Protobike 2 will be a fully driveable Hoverbike, and a giant leap towards mass-market in the professional field.

  • Electric Drivetrain w/Hydraulic Suspension - We plan to integrate an electric motor, delivering more torque and off-the-line acceleration than the most powerful 1000cc sport bikes in production - along with the benefit of a more compact powerplant. Also, use of a hydraulic suspension will allow the wheels to retract into and extend out of the body of the vehicle. This is to reduce drag and streamline aerodynamics of the vehicle when in flight. We plan to separate the suspension from the steering column and braking system by use of a purpose-built steering column. The drivetrain incorporates lightweight, supersport class elements - such as magnesium wheels, Brembo brakes, purpose-built Lithium-Ion Battery Packs, etc.

  • Hover Engines & Assemblies - A system of safely integrated, high power microjet engines are envisioned to propel the vehicle forward and in VTOL (Vertical Take-Off and Landing) when wheels are no longer in contact with the ground. Each engine will be equipped with appropriate plumbing/safety systems. Rosa's R1 can utilize sustainably-sourced biofuel such as Bio-SPK to replace traditionally sourced Kerosene/Jet A. In addition, the R1 is one of the world's smallest turbofan engines, reducing fuel consumption and noise output. ROSA aims to become a leader in the production and/or distribution of such fuels in the long-term and will take action to limit or prevent the operation of their vehicles with pollutant fuels. We calculate propulsive force to throttle up to a many hundred lb-ft of thrust, and expect the top speed to be several hundred miles per hour. 

  • Body, Flight Control Surfaces, Dashboard & Electronics - We plan to integrate an entire painted body, as well as motor driven wheel doors, flight control actuators, head/taillights, etc. We hope to introduce a next-generation dashboard that forms a vibrant control arc in the rider's view. This also includes the vehicle's computer, sensors, and electronic controllers.

This vehicle, when completed, will be a drivable and mature Hoverbike. It is intended to be the precursor to a refined professional model further down the line. Professional-spec models will require flight training and other regulatory aspects due to the higher-performance characteristics, along with increased weight compared with consumer-spec models. We hope to reduce the learning curve of the vehicle as well as design for regulatory constraints. 

PROTOBIKE 3 'SCARLETT' (2020)

Manned Prototype Flight Vehicle currently under development

After completing Protobike 1, we have confirmed the most fundamental engineering questions and gained a more thorough understanding of the practical design of our technology. The next step is to advance towards mass-market through a series of prototype vehicles. For this Protobike 3, we plan to integrate an electric drivetrain, moderate-power flight engines, flight control, hydraulics, and electronics among other components such as fairings (finally!). Designed for consumer applications, Scarlett is a moderate-power adaptation of our platform. It is designed in compliance with FAA ultralight constraints, eliminating the need for a pilot's license or registration. Protobike 3 will be a fully driveable Hoverbike, and a giant leap towards mass-market in the consumer field.

  • Electric Drivetrain w/Hydraulic Suspension - We plan to integrate an electric motor, delivering more torque and off-the-line acceleration than the most powerful 1000cc sport bikes in production - along with the benefit of a more compact powerplant. Also, use of a hydraulic suspension will allow the wheels to retract into and extend out of the body of the vehicle. This is to reduce drag and streamline aerodynamics of the vehicle when in flight. We plan to separate the suspension from the steering column and braking system by use of a purpose-built steering column. The drivetrain incorporates lightweight, supersport class elements - such as magnesium wheels, Brembo brakes, purpose-built Lithium-Ion Battery Packs, etc. The drivetrain of Scarlett shares similar performance characteristics with Kirby and has minimal compromise in this field.

  • Hover Engines & Assemblies - A system of safely integrated, moderate power microjet engines are envisioned to propel the vehicle forward and in VTOL (Vertical Take-Off and Landing). Rosa's R2 can utilize sustainably-sourced biofuel such as Bio-SPK to replace traditionally sourced Kerosene/Jet A. In addition, the R2 is the world's smallest turbofan engine, reducing fuel consumption and noise output. Each engine will be equipped with appropriate plumbing/safety systems. Scarlett will be able to reach ground speeds of over 130mph and flight speeds of 60 mph, all while weighing under 250 lbs.

  • Body, Flight Control Surfaces, Dashboard & Electronics - We plan to integrate an entire painted body, as well as motor driven wheel doors, flight control actuators, head/taillights, etc. We hope to introduce a next-generation dashboard that forms a vibrant control arc in the rider's view. This also includes the vehicle's computer, sensors, and electronic controllers.

This vehicle, when done, will be a drivable and mature Hoverbike. It is intended to be the precursor to a refined consumer model further down the line. Weight is a prime factor in the design of this vehicle. We are working for a significantly low dry weight of under 250 lbs by itemizing every component of the vehicle for weight reduction. Traditional electric motorcycle manufacturers do not design with this level of weight reduction in mind since flight is not a concern, and instead opt for offsetting power-weight by increasing power. We instead opt to offset weight in this relationship while maintaining power in excess of the vehicle's needs. We envision eliminating the need for a pilot's license and aircraft registration under the FAA's 'Ultralight' classification.

Proudly founded for a better future.
