—  about cats  —

The CHICAGO AREA TANDEM SOCIETY is a bicycle club formed of members primarily located in the suburban area surrounding Chicago Illinois USA. Membership consists of just under 100 riders. There are only 2 meetings a year, one in February for our planning session to determine the year's rides, and one in October as a recap for the year. We have approximately 15 rides a year starting in May and ending in December primarily on a Saturday or Sunday. There is a ride called the Prairie State Tandem Rally we try to sponsor once a year as an invitational to other tandemists. Approximately every 6-8 years we sponsor the larger Midwest Tandem Rally.

Founded as an off-shoot of hosting the 1984 Midwest Tandem Rally, the Chicago Area Tandems (later changed to Chicago Area Tandem Society) has become more than just a means of riding with fellow tandemists. It has developed many relationships, including friendly rivalries with other tandem clubs around the nation. Many clubs adopted the animal name and carried on the fun.


From our beginnings of simply having monthly rides, we have expanded to occasional overnight rides in different states as well as attending the annual Midwest Tandem Rally (MTR) each year as a group. Basically we remain a friendly group of folks who enjoy riding together and promote the healthy and social sport of tandem bicycling.

Any tandemist will tell you that riding a tandem is great fun, and a good deal more social than riding a single. What you might not know is how much more fun it is to ride with other tandemists. It's hard to beat the exhilaration of riding in a pack of a dozen or more cruising tandems.

Tandemists naturally band together, because tandemists are, by nature, a little different than the average single bike rider---we have tandems. And we love 'em! You can't be an anti-social tandemist! Our membership is made up of teams from all over the Chicagoland area, we even have some members in other states. Member's ages range from 3 years old to 86 years young. We have teams that ride 100-mile rides every weekend, and teams that barely get a 100 miles in during the year. There are speed demon teams and there are teams that amble along at very comfortable paces. Whatever your style or pace, you'll fit in.


Most weekend rides start at 9 a.m. and are between 25 and 65 miles in length. Often, for some reason, food is a factor on rides, either in riding to a restaurant and back, or riding out and back to a restaurant. As always, the goal on any of our rides is to have fun, and enjoy each other's company.

We are affiliated with many national and local advocacy groups, such as the League of American Bicyclists, Ride Illinois, the Active Transportation Alliance, and the Tandem Club of America,.

CATS is organized to maximize the fun and minimize the effort to make it happen. Volunteerism makes it all work. All members ride entirely at their own risk. Members encourage everyone to wear helmets, obey the rules of the road, and to ride safely at all times.

No matter what style of riding you like, no matter what type or age of tandem you have;(or even if you don't have one yet); no matter your age or condition; you'll find you're welcome in CATS as long as you like tandems.
