History of bicycle

What was one major design challenge faced by early bicycles in achieving higher speeds?

• The pedals were too far from the ground.
• The pedals were directly attached to the wheel.
• The wheels were too small.
• The handlebars were too low.

How did increasing the size of bicycle wheels affect speed?

• It increased the weight of the bicycle.
• It allowed the bike to travel farther with each rotation.
• It reduced the distance traveled per pedal rotation.
• It made the bike harder to steer.

What was a common issue with early bicycles known as 'bone shakers'?

• They were uncomfortable on uneven surfaces.
• They were too fast.
• They had no gears.
• They were too heavy.

What was a significant drawback of the high wheel bicycle design?

• It was too slow for racing.
• It was too heavy for casual riders.
• It had a low center of gravity.
• It was difficult to balance due to its height.

What mechanism was developed to allow different sized gears to work together without reversing rotation?

• The brake system
• The pedal system
• The chain drive
• The wheel axle

What is a trade-off when designing bicycles regarding speed and torque?

• Higher speed requires more weight.
• More torque reduces the ability to steer.
• Increased torque can decrease speed.
• Larger wheels provide less torque.

What was one of the initial solutions to the problem of needing more torque in bicycles?

• Using smaller wheels
• Flipping the rear wheel to change sprockets
• Adding more pedals
• Increasing the weight of the bike

Which historical development in bicycle gearing systems was first introduced in 1895?

• The introduction of disc brakes
• The first multi-gear chain-driven bicycle
• The penny farthing design
• The use of lightweight materials

How did innovations in gear systems influence bicycle racing?

• They increased the cost of bicycles.
• They were initially rejected by racing organizations.
• They allowed for easier gear switching.
• They made bicycles heavier.

What was a significant change in bicycle design accepted by the Tour de France in 1937?

• The implementation of disc brakes
• The adoption of larger wheels
• The use of derailleurs for gear shifting
• The introduction of lightweight frames
