The mechanics are our most important asset, and the repair department is the heart and soul of our business. Our repair areas are visible to customers, and we invite you to have a look.
Cosmic Bikes is home to some of the most senior, continually working bicycle technicians in the city. While anyone can grasp the basics of bicycle repair, true expertise in this field, as in any highly specialized trade, comes only through years of work and hands-on experience. Our mechanics have honed their skills at some of the most respected and demanding repair shops in Chicago, making our Service Department second to none.
Our mechanics are passionate about their work, highly skilled, personable, and, because they are themselves cyclists, they can clearly explain how the recommended repairs will improve your ride. You can count on their expertise, and solid, street-tested advice, and have the confidence that when you bring your bike in for repair, you're leaving it in good hands.
We cannot offer estimates online or over the phone, however when you come in with your bike, you will receive a complete estimate for your approval, including labor, parts and time-frame for completion, before we proceed with any repairs.
A thorough estimate is the foundation of solid service, and can forestall surprises and unexpected costs down the road. Before we proceed with an estimate, we try to find out a little bit about you, your projected use of the bike, and your relationship to it. Please understand that we always recommend the most complete solution that will ensure the safety and longevity of the bike, and give you the best riding experience. If possible, we can scale the repairs to match your budget, as long as safe functioning is not compromised.
Our labor estimates are $25, which will be deducted from the cost of the repair if you decide to proceed, or —if not— applied to the purchase of a new bike at Cosmic Bikes within six months.
Safety inspections of bicycles and helmets used solely by children under the age of 18 are always free.

The Fine Print
Please keep in mind that the prices listed are for Labor only. Many bicycles will require replacement parts for safe and proper functioning.
All bicycles, including children's bikes, are vehicles, and require certain components to operate properly to ensure safety. We cannot be responsible for the safety of the components that you do not allow us to service or replace, and may therefore decline to perform any repair that will not result in a safely operating bicycle.
We charge $5 supply and recycling fee on all our major tune-ups, complete assemblies and custom builds, and some a la carte services. This is to help offset the cost of cardboard recycling, and shop supplies and materials, including cleaners, lubricants, small hardware and shop towels.
All of our labor is guaranteed for 30 days. Specific services carry longer guarantees, as described above. We stand behind our services, and promise to make any needed corrections or adjustments free of charge during the period covered by the guarantee.
In rare cases, additional parts may be needed to correct the problem. With the exceptions of inner tubes on warranty flat repairs, additional parts are not included in the guarantee.
In order to keep track of your repair history, we keep detailed records of your services under your account. Our Labor Guarantees are non-transferrable, and apply only to the original purchaser.
