"2 FORM BIKE"

Two-form bike

The “2 FORM BIKE” is an innovative solution that combines the advantages of recumbent and upright bicycles. Thanks to its unique design, users can switch the bike’s configuration from traditional to recumbent and vice versa in just one minute.

The recumbent bicycle provides superior aerodynamics, greater speed, and comfort, while the upright configuration allows better visibility in urban traffic and easier overcoming of terrain obstacles. Patented worldwide, the “2 FORM BIKE” eliminates the need to choose between one model or the other, offering versatility in one vehicle.


Motivation

Recumbent and upright bicycles each have their unique advantages, as well as limitations:

Recumbent bikes are faster, more aerodynamic, and comfortable, but can be less visible in urban traffic and more challenging to maneuver on uneven terrain.

Upright bikes provide greater stability, better visibility, and easier handling, but are less comfortable on long journeys and generate more air resistance.

The “2 FORM BIKE” resolves this dilemma, offering instant configuration changes depending on riding conditions. As a result, recumbent cyclists gain mobility in urban spaces, and enthusiasts of classic bicycles can enjoy the comfort of a reclining position.


Prototype and Design Development

We currently have a working prototype that has passed the testing phase. The final version is ready for production, optimized for durability, lightweight construction, and ease of use.

Prototype 1

Prototype 1

Prototype 2

Unlike the original prototype, the second design does not include a Cardan joint. The tubes rotating within the steering tubes are connected by a cable, which does not need to be removed during transformation from the recumbent to upright position. Our design can easily become the basis for mass production.


Formal Status and Patents

The “2 Form Bike” project is protected by patents:

📜 International Patent PCT/IB2019/051265
📜 National patents in the USA, China, India, Brazil, and Poland

These protections enable technology development and implementation on the global market.
