Specifications for the rear bike wheel
- Decided "Pit Bike" rear wheel looks right.
- Decided Steel rails for side (stronger ... & fast to make)
- Decided would prefer rear wheel of at least 30cm (12in) diameter ("direct" speed 24kph 10:14 speed 18kph, 14:10 speed 35kph) ... preferably more !
- Decided must be at least 20cm wide tyre at back (8 inches) preferably more.
- Drive chain sprocket on one side, and disk brake on the other.
- This means axle must be "rotating", and "floating" (ie wheel slides on)
- This means cannot use standard ATV axle (too wide ... and cannot cut down +++ not 'floating' axle)
- Choices: (1) find a different kind of hub for ATV wheel, or (2) use Kart parts.
- Carefully considered options. Choices, in order of preference are: (1) Start with full cart, and adapt rear axles (with perfectly "floating" parts) to single wheel + create adaptor for ATV rear wheel; (2) Start with full "ATV Buggy" (ie already large wheels); (3) Start with Quad bike 125cc +, and adapt rear power to single wheel.
Timing now
- Each morning, do "saved" search for: (1) Kart rolling chassis (no motor) for under $350; (2) ATV buggy with huge wheels, for under $300; (3) ATV quad 125cc ++ under $200.
- Create accelerator (can swap the potentiometer)
- Create vacuum electronics
- Create balsa/fibreglass rails for future use.
