Freee F2 Balance Wheelchair – Segway PT Based
The Freee F2 is an active self-balancing electric wheelchair based on the Segway PT platform. Acceleration and braking are controlled through movement of the rider's centre of gravity, while direction is controlled through the steering bar.
A distinctive feature of the Freee F2 is the seating and parking-support system developed by Fried Kunststofftechnik. The electrically controlled parking supports stabilise the vehicle for transfers and automatically adapt to the surface.
PT Pro provides Freee F2 vehicles, accessories, spare parts and technical service, supported by extensive experience with Segway PT-based balance wheelchairs.
Freee F2 – Active Balance Wheelchair Based on Segway PT
The Freee F2 is a self-balancing electric wheelchair developed by Fried Kunststofftechnik and based on the Segway PT platform.
It combines Segway PT electronic balancing technology with a purpose-developed seating system, steering bar, footrest and electrically controlled parking supports.
This places the Freee F2 within the generation of classic Segway PT-based balance wheelchairs and Seat-Segway systems.
How Is the Freee F2 Controlled?
The Freee F2 uses an active control concept. Speed is controlled by shifting the rider's centre of gravity.
- shift forward: move forward and accelerate
- shift backward: decelerate, stop or reverse
- move the steering bar left or right: change direction
The electronic balancing system continuously stabilises the vehicle on its two parallel wheels.
Suitable physical control is therefore required, and individual suitability should be assessed during a practical test ride.
Dynamic Balancing Technology
According to Fried Kunststofftechnik, the Freee F2 stabilisation system uses five gyroscopes to continuously monitor terrain and body position for electronic balance control.
This allows the vehicle to travel on two wheels and turn on the spot.
Electric Parking Supports for Stable Transfers
A distinctive feature of the Freee F2 is the parking-support technology developed by Fried.
The integrated supports are electrically controlled and automatically adapt to different surfaces. When parked, they stabilise the vehicle and provide a stable position for transferring into or out of the seat.
Adjustable Freee F2 Seating System
Depending on vehicle and configuration, the Freee F2 can include:
- adjustable and folding backrest
- replaceable seat cushion
- adjustable transfer supports
- adjustable and removable steering bar
- adjustable footrest
- electrically controlled front and rear parking supports
The actual equipment should always be taken from the individual vehicle description.
Key Freee F2 Specifications
Specifications can vary depending on vehicle version and configuration. Available Freee F2 information includes:
- Technical platform: Segway PT
- Vehicle width: approximately 68 cm
- Vehicle length: approximately 81–89 cm
- Height including backrest: approximately 87–95 cm
- Vehicle weight: approximately 74–75 kg
- Maximum user weight: up to approximately 110 kg
- Batteries: two lithium-ion batteries
- Charging time: approximately 8 hours from empty
- Steering bar: adjustable and removable
- Footrest: adjustable
- Parking supports: electrically controlled
Speed and range can vary according to vehicle configuration, programming, battery condition and applicable legal requirements. The specific vehicle and its documentation are therefore decisive.
Freee F2 as an Active Wheelchair
The term active primarily describes the Freee F2 control concept. The rider actively influences acceleration and deceleration through movement of the body's centre of gravity.
This differs significantly from conventional joystick-controlled electric wheelchairs.
Freee F2 or Genny 2.0?
Both the Freee F2 and Genny 2.0 belong to the generation of Segway PT-based balance wheelchairs.
Both use Segway PT self-balancing technology but differ in seating system, parking supports, steering, equipment and construction.
Freee F2 or Genny Zero?
There is a fundamental technical difference between these vehicles.
The Freee F2 is based on the Segway PT platform and uses its balancing, drivetrain and battery technology.
The Genny Zero was developed as an independent modern balance wheelchair and is not based on the Segway PT platform.
A current comparison should therefore consider not only handling and comfort but also spare-parts availability, battery technology, serviceability and long-term use.
Freee F2 or Hoss R1?
The principal difference is the control method.
The Freee F2 uses active body weight shifting for acceleration and braking.
The Hoss R1 is joystick controlled and does not require weight shifting for driving.
The appropriate concept depends on trunk stability, hand and arm function, preferred physical involvement and individual requirements.
Segway PT Spare Parts and Technical Support
Because the Freee F2 is based on the Segway PT platform, many of its technical components are directly related to Segway PT technology.
Depending on the technical case, PT Pro provides:
- Segway PT batteries and battery technology
- InfoKey diagnostics, repair and programming
- gearboxes and drivetrain components
- tyres, wheels and rims
- electronics and sensors
- steering and attachment components
- diagnostics, maintenance and repair
Freee F2 Batteries
The Freee F2 uses the two-battery system of its underlying Segway PT platform.
Particularly with older vehicles, the actual condition of both batteries should be assessed. Age or displayed charge level alone is not sufficient to determine battery performance.
PT Pro provides diagnostics, repair and suitable technical solutions for Segway PT batteries.
InfoKey for the Freee F2
As a Segway PT-based vehicle, the Freee F2 uses the Segway PT InfoKey.
PT Pro can diagnose and repair suitable InfoKeys and program appropriate replacement or second InfoKeys. Suitable proof of ownership is required for programming.
Freee F2 Test Ride
A practical test ride is particularly important with an actively controlled balance wheelchair.
It allows seating position, transfer, parking-support operation, trunk stability, weight shifting, acceleration, braking, steering, manoeuvrability and everyday suitability to be assessed.
Transporting the Freee F2
The steering bar and various seating components can be adjusted, folded or removed to facilitate transport.
The specific vehicle should nevertheless always be checked against the available car. Loading opening, loading height, vehicle weight and any required ramp or lifting system should be considered before purchase.
Registration and Public-Road Use
With Segway PT-based balance wheelchairs, vehicle configuration, speed, registration status and available documentation can affect legal use.
The legal status should therefore always be assessed for the specific vehicle and according to the applicable national regulations.
PT Pro Service for Freee F2
PT Pro combines Freee F2 support with extensive technical experience in Segway PT and Segway PT-based balance wheelchairs.
Depending on the technical case, this includes diagnostics, maintenance, repair, battery technology, InfoKey service, gearbox service and spare-parts supply.
Who Can the Freee F2 Be Suitable For?
The Freee F2 can be particularly relevant for users looking for an active balance wheelchair with weight-shift control, an adaptable seating system and electrically controlled parking supports.
Because it is based on the Segway PT platform, a current purchasing decision should also consider the age and condition of the technical platform, batteries, spare-parts availability and long-term serviceability.
PT Pro therefore recommends a practical test ride and direct comparison with other current balance and electric wheelchair concepts.
