Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the vehicle classification?Human-powered two-wheeled vehicle utilizing a chain drive for propulsion
2. Why is a safety bicycle safer than the old penny-farthing?Because the safety bicycle has a lower seat and two equal wheels, it keeps the rider's weight closer to the ground. This makes it less likely to tip over or fall.
3. How does the chain drive help a safety bicycle?The chain connects the pedals to the rear wheel, so the rider can pedal without turning the front wheel. This lets the bike use gears and makes it easier to climb hills or go faster.

Penny-farthing: An early bicycle design featuring a large front wheel directly driven by pedals, known for its instability and difficulty of use.
Chain drive: A mechanical system that transmits rotational force from a power source (pedals) to a driven component (rear wheel) via a chain and sprockets.
Center of gravity: The average location of an object's weight, crucial for determining its stability and balance.
