BUILT AROUND THE WHEELCHAIR
Attach. Align. Move.
LegMaker is being developed as a patented, compact motor-assisted pedal unit designed to attach to 16-, 18- and 20-inch manual wheelchairs, with a focus on lower-limb movement, configurable sessions and connected software.
Lower-limb focus
Seated leg exercise with configurable cadence, resistance and session duration.
Connected sessions
Planned patient and provider software for RPM, duration, power, resistance and other session metrics.
DESIGN PREMISE
Start with the mobility system people already use.
The chair stays central.
LegMaker is designed around a seated wheelchair setup rather than a separate exercise station.
Movement becomes configurable.
The product direction brings passive, active and resistance-based exercise into one motion architecture.
Sessions become readable.
Connected software is planned to organize device settings and session information in a clear experience.
WHY LEGMAKER
Exercise technology should adapt to the person’s existing mobility setup — not ask the person to adapt to the machine.
THREE MODES
One platform. Different levels of support.
MOTOR-ASSISTED
Passive motion
The system drives the pedal cycle to provide continuous lower-limb movement.
Assist
Passive
Motor-assisted cycling where the system provides the movement.
Active
User-driven movement with session sensing and tracking.
Resistance
Adjustable resistance with up to 15 planned levels for progressive training.
LEGMAKER PROTOTYPE
Built around the wheelchair.
Real development hardware showing the LegMaker attachment, wheelchair integration and current prototype configuration.
Prototype shown for development illustration. Product configuration and specifications may change.
A SMALLER FOOTPRINT
Designed to meet the chair — not replace it.
LegMaker’s product direction centers the wheelchair itself, with the motion unit positioned around the user’s existing seated setup.
PHYSICAL AI + CONTROL
Adaptive by design.
LegMaker’s architecture is being developed around closed-loop sensing, responsive resistance control and connected software for a more measurable exercise experience.
