Sometimes a BUG performs a social function. It's there as a way to organize rides, get-togethers, and social events among people who bike, would like to bike, or like people who bike. You can also talk to other BUGs about their successes and frustrations. Many BUGs work towards getting better parking and shower facilities at their workplaces. Some BUGs create projects and events for the annual Bike To Work Week.
Some BUGs are theme related.
Some BUGs form within residents' associations and among users of certain streets. Some BUGs are big and electronically connected. The CIBC BUG has over 120 members who communicate by office e-mail. And there are all sizes and purposes in between. Some BUGs keep on ticking, acting, and dialoguing.
