Design considerations for rickshaw construction and stability
18 years old. Gear and prices may have changed since.
DisputedParticipants disagreed and reached no conclusion. Read the findings as positions, not as an answer.
What the thread found
- Rickshaw designs can be categorized as top-slung (frame mounted higher) or underslung (frame mounted lower), which affects stability and balance characteristics.
- The vertical position of the attachment point and force displacement relative to the wheel axle influences how a rickshaw handles during acceleration and deceleration.
- A design where the combined weight of rider and equipment is positioned to place force distribution behind the wheels rather than entirely forward improves safety by reducing forward flip risk.
- Lowering the center of gravity and force displacement point helps prevent the rickshaw from tipping forward over the wheels.
- Adjusting wheel position backward or forward can help achieve desired center of mass placement relative to the wheel center.
- Bicycle wheel size options for rickshaw construction include both 20-inch and 26-inch wheels.
Depends on
- The discussion does not provide definitive experimental data comparing rickshaw designs under various load and speed conditions.
- The physics explanation regarding force displacement and stability contains some conflicting interpretations among participants that were not fully resolved.
- The practical safety implications of different design choices are discussed theoretically but not backed by crash test data or field accident reports.
- Specific recommendations for wheel size selection are requested but not answered in the thread.
