Krater
After 100+ parts and 45 hours of practice, I did it
A video on YouTube. In Science & Engineering, a Krater category.

An engineer tries to build the world's smallest working bicycle, redesigning parts through multiple iterations to match and beat the Guinness World Record size while remaining rideable.
From the video
Answers: Can you build and ride a bicycle smaller than the world record?
- micro-engineering
- bicycle design
- CNC machining
- 3D printing
- world record attempt
What it concludes
- A bicycle built with a frame and pedals scaled down to 5.3 cm is fully rideable with enough practice and proper geometry.
- Pedals placed too close together or extending too far past the front wheel cause the bike to tip forward and twist uncontrollably.
- Using a belt drive system with a one-way bearing in the rear wheel allows the bike to coast when not pedaling.
