Two wheels are becoming more popular than four.
Bike shops are reporting strong interest in bicycles as people turn to pedal power rather than petrol power.
Cargo bikes (also known as utility bikes), which can carry heavy loads and children, have become very popular as people choose to use them rather than vehicles to do grocery runs or take children to school.
Bike House salesman Paul Gough said the store had noticed an increase in people buying bikes in the past couple of weeks.
Some people were looking at e-bikes, but most were choosing regular bikes which varied in range and price.
Many who had bought bikes said the reason was to get away from motorised vehicles.
He said the cargo bikes were being used by people for jobs and to carry children. They had become more popular over the past couple of years.
People from all walks of life were buying them, he said.
Supply was becoming tight for the next few months as demand ramped up, Mr Gough said.
Prices for the bicycles had remained relatively stable, though might increase in the future, he said.
Evo Cycles manager Jamie Fraser said there had been an increase in cycle sales over the past few weeks.
It appeared the rise in fuel prices had been the tipping point for many when deciding to buy a bike.
They had wanted to buy one for some time, but decided now was the right time to take the plunge.
He said most people were buying regular bikes, aiming to use them for recreation and also to get to work or use around town.
