Riding a bike around is a great way to get around in urban environments with lots of traffic. Kwiggle is one of the most compact bikes around. It weighs only 8.5 kg and can be unfolded in 10 seconds. It fits into carry-on luggage sizes 55x40x25 cm.
The bike lets you travel at speeds up to 30 km. It supports riders up to 92kg. The Kwiggle bike is made of high quality materials. You can find it on Kickstarter at this time.
