which of the following changes will increase the demand for bicycles?

An increase in the demand for bicycles comes from changes in buyers’ preferences, incomes, or related conditions, not from the bike’s own price changing. In other words, anything that makes more people want bicycles at any given price will shift the demand curve to the right.

Key ideas: what raises demand?

Typical changes that would increase demand for bicycles include:

• Higher income for people who like cycling (if bicycles are a normal good for them).

• A new health or fitness trend that makes cycling more popular as exercise or transport.

• Greater concern about the environment or climate change, making bikes more attractive than cars or motorbikes.

• Higher fuel prices, making biking a cheaper commuting option relative to driving.

• Better cycling infrastructure (more bike lanes, safer routes, new bike paths) that makes biking easier and safer.

• Urban congestion and parking problems that push commuters toward bicycles and e‑bikes.

All of these shift the demand curve for bicycles to the right because, at each price, more people are willing and eager to buy.

What does not count as higher demand?

Some changes affect supply or cause only a movement along the demand curve:

• A fall in the price of bicycles: this increases quantity demanded , but is just a movement along the existing demand curve, not a shift.

• Better production technology that makes bikes cheaper to produce: this shifts the supply curve, not demand, even though the market quantity sold may rise.

• A new, more fashionable substitute (for example, if scooters or rollerblades suddenly become the cool choice): this would decrease demand for bicycles, shifting demand left.

So, if your multiple‑choice options include things like “incomes of bike riders rise,” “cycling becomes trendy,” “fuel prices go up,” or “more safe bike paths are built,” those are the ones that increase the demand for bicycles.
