Strange question.
A bicycle is a fabricated mechanical machine, so you need the raw materials, metals. plastics, rubber...
Then you need the factories that can turn these into useful bits, tubes, axles, nuts and bolts. Then you need someone to assemble the whole thing.
Depends on what you mean. Building a bicycle from scratch requires some pretty serious metal working tools, grinders, drills, hacksaws, welding/brazing equipment. And then a good bunch of hand tools, and a smaller bunch of bicycle-specific tools.
If you're just talking about assembling a bicycle from parts, then it's easier. Some torx keys, some Allen keys, a screwdriver or two. Bke specific bottom bracket, cassette tools. A hacksaw for the steerer tube. Pliers for the cables.
It needed a trick cyclist.
Pretty much all of them
People needed to get to places but they did not have a car.
It means that the thing which is being referred to is totally unnecessary, just like a bicycle is not needed by a fish.
You would need 317 pedal turns are needed to travel a mile on a bicycle.
The frame is needed to hold the different parts together to form a rideable vehicle.

Force is directly proportional to mass. Therefore, even both the car and bicycle are being accelerated to the same velocity, accelerating a car would require more force since it has a greater mass.
Most tandems can be ridden by one person, although they're meant for two.
F = M A = (80) x (1.85) = 148 newtons

Most bicycle owners maintain their own bicycle. But, a bicycle shop may be willing to maintain a bicycle, if you ask.
