But hipsters could be ready to one-up themselves again with a new take on wheeled transport, which uses a treadmill instead of pedals.
For riders of the Lopifit, getting from A to B is as easy as putting one foot in front of the other, with its quirky design enabling users to ride around by walking.

Designed by Dutchman Bruin Bergmeester, the electric walking bike called Lopifit is a blend between a scooter, an electric bike and a treadmill.
, bike enthusiast Bergmeester came up with the idea while training in the gym, pondering: How can I use the treadmill outdoors? What about a treadmill on wheels?
Four years ago the initial concept was created in the Netherlands, now the Utrecht-based firm is distributing the bikes to several countries, including the United States, Mexico and the Caribbean.
The bikes use a motor to
assist the treadmill
, so using the bikes takes no more effortthan a walk in the park.
As the rider walks, sensors register the turning treadmill and kick the motor into gear to assist the movement and set the wheels in motion.
According to its makers, the bikes can travel 30 to 50 miles on a charge and a selection of gears enable the user to change the walking pace from a leisurely stroll to a brisk walk.
Depending on terrain, gear selected and how energetic the user is feeling, it can achieve speeds between 417 mph (627 kph).
On downhill stretches a freewheel kicks in, so users dont have to break into a sprint to keep up.
Lopifits bikes come with a hefty pricetag, at $2,495 (1,980) per bike. But bikers can customise their walking bike with a range of colours.
, the company is currently struggling to keep up with demand.
Its name comes from a combination of three words - 'lopan' (the Dutch for 'walk'), 'pi' for the technical aspects, and 'fit' for healthy living.
from earlier this year said: Our goal is to make the electric walking bike available for as many people as possible. We want to change the way people move.
We wish that everyone can benefit from a greener and cleaner way of transportation that simultaneously improves your health.
