Chicago's #1 tourist bike rental shop with a convenient location at Millennium Park. See images of the bikes they rent on their website, but suffice to say they have something for all riders, from city cruisers to road bikes.
If you have a large group (10 or more), you can send an email to the store and they will arrange a group ride for your party. Inline skate rental available too, as are fun quad cycles and tandem bikes.
There are additional locations around the downtown Chicago area: Navy Pier, Riverwalk, North Avenue Beach, Museum Campus on Lake Shore Drive, Oak Street Beach and Ohio Street Beach.
