Picture of Fat & small wheel bicycle

I built the bicycle from a used childen bicycle fame, and repainted in black. The two wheels are small and fat trolley tyres. And I redesigned the brake system.

How did you mate a sprocket to the wheels? Can you publish the full instructions?
How is the gearing? Part of the mechanics of gearing on normal bike tires is size of the wheel itself. Those small wheels will have to spin 3 times as fast as normal wheels. Not much use if you have to peddle faster than you would walk.

Cool bike! Can you share some of the modifications you made to adapt the small wheels?

It doesn't look easy to ride...

Hang on, does the back brake grip the tyre??

I am 175cm, 80kg, it is easy for me to ride

Yes, the back one is solid tyre.
