Visitors to the Czech Republic (also known as Czechia) will discover that virtually everyone who has the ability to ride a bike does so. That's what we noticed on our recent trip to the country.
Also, bicycling is not simply a leisure activity for Czechs, but it is also a means of transportation for many.
It didn't matter what time of day it was or what the weather was like, Czechs were on bikes, whether it was sunny, cold, rainy, or windy. From babicky (grandmas) on one speed bikes without helmets and children to traditional cyclists in Lycra with helmet and all the gear, cyclists were frequently found in or between villages, heading for somewhere. Whether in the morning, afternoon, or after sunset, it didn't matter the time of day, bicycles were on the road.
Not only were cyclists on the road, but they also enjoyed exploring signed bicycle paths, which form a web across the country. Czechia has thousands of kilometers of such paths that allow cyclists to enjoy the green countryside (in spring and summer) without the buzz of traffic nearby. When my wife and I took a one-day cycling tour, we saw many retiree-age riders early in the day. By late afternoon, a younger, teenage to middle-aged crowd was out enjoying the beautiful day.
During our travels around the country, we also saw busses which were specially equipped to hold bicycles vertically in a rear compartment. In Hradec Kralove, we witnessed an enclosed, see-through bicycle parking house, which was the only one of its kind in Europe as of 2015. The parking house held bikes, several stories high, for a nominal fee; the bikes would be robotically lowered to street level when the owner came to claim them (see http://www.alamy.com/stock-photo-parking-house-for-bikes-hradec-kralove-bike-cycling-parking-lot-parking-89653206.html for images of the parking house).
Overall, it was highly encouraging to see how a small country (1/3 the size of Kansas) can create such a great bicycling infrastructure. United States, it's time for you to step up to the plate!
