Conclusions
Next steps

3. Narrow-Track, Tilting, Recumbent Tricycle
“Narrow-track” means it doesn’t take up the whole bike path/road.
“Tilting” makes it stable at high speeds even with a narrow axle track.
“Recumbent” makes it comfortable to ride, reduces air drag, and allows for a full enclosure.
“Tricycle” means you can ride easily at low speed and stop without putting your feet down.

4. Analysis
Unstable
Stable

5. Physical Testing

6. Conclusions Kinematic analysis verified by physical testing
Tricycle exhibits two distinct modes (stable and unstable) with semi- stability during the transition
Resulting design carries a provisional patent

7. Next Steps Derive equations of motion for the tilting trike
Perform physical testing to validate the derived equations of motion
Implement a truly user-controlled bell crank with mechanical actuation
Begin to design a new vehicle that will offer better aerodynamics, handling, comfort, and adjustability
