    I came to Chicago, slept for three hours on the plane, and I was still full of energy. So, my friend and I decided to take a bike and ride from the suburbs to downtown. The maps showed us that it would take about two hours. Unfortunately, halfway through our ride, my bike's rear tire blew out. But we were lucky enough to be near Cosmic Bike. We got there 10 minutes before it opened, but the employee was friendly and kind and took my bike right away. We waited about 15-20 minutes, which I was glad about because it's pretty quick. After that I was able to ride for about three more hours with no problems. Thank you very much! P.S. The first photo shows a broken tire, the second a repaired one.

    Great find of a place since it been around forever. I was surprised to find this place using my internet search. I usual frown upon finding places at the last minute. To my surprise, they had a place to get my bike inner tube in stock although my tube was a common size. It's one of those things that when you want to find something now, you need it get it fast and at a reasonable price. I have seen a bunch of bikes stores that would charge you an 'arm and leg' to get something basic like this. I am not sure if there prices for other things and I would think it would be competitive enough since you can get things online these days. As with any higher priced item over $300, I would check online. Anyways, it was a nice thing to meet friendly people on staff and older guys like myself to handle and work with customers. Check out my other reviews and smash the thumbs up button on a few of my pictures and reviews if you find something useful. Swipe left on my other reviews and click on pictures.

    We bought a cargo bike and the customer was incredible here. A very big thank you for helping us find the right option, for your patience and care, and for delivering it.

    I really like this place, my wife and I used to be very avid bike riders. Until my older son borrowed my bike left a chained in the rain. Don't have kids. However, I blew a flat which tore my brake system off. Weird accident. I called, Chris said he had a huge delay, but just to take care of the flats with insulation was a quick pitstop. I will bring my wife's bicycle here for a tuneup, I like the way they work here. Very professional. And some products, Surly. And city style bicycles. While shopping, I searched Walmart, for basics, like gel chairs etc. Cosmic bikes was only a few bucks range, give or take. These folks are nice, and I decided to buy some accessories with my tuneup. Support good local vendors.

    Always reliable and fair pricing. Convenient location on Broadway. I mean if you get a flat on LSD…read moreit's relatively easy to walk over to Broadway since it runs parallel and throw your bike on a bus. For my single speed and racing bikes always on time with good service and fair pricing. Nice selection and if you don't see it they have no problem ordering direct. Quality small local business. Check them out, Spring is coming.

    In response to the (mostly) positive reviews to this place, I trusted them to provide quality…read moreservice. My rating is due to bike service issues, not personnel. The workers were what you'd expect as far as being nice - but the mechanics are amateur at best. After my first disappointment with their routine "maintenance service", I wanted to give them another shot with my brakes. After all, I yearn to have a good relationship with a local bike shop. And sadly, it's a bigger disappointment than my first visit. I asked for them to bleed both brakes. I received a call saying they're "fine" and suggested NOT bleeding brakes; but the pads and rotors were caked in oil and other residue (I cleaned them both 3 days ago). But I figured you gotta trust the pros, right? Wrong. I figured they'd replace the pads, clean the rotors and call it a day. After all, I hadn't sanded the pads this past time and they are getting old (10 months). Nope, just VERY poorly sanded the existing brake pads, cleaned the rotor below my normal standard and was charged nearly $50. For that. To sand 4 little brake pads and (presumably) apply some rubbing alcohol to the rotors. $50. Look at the picture of the brake pads after they serviced them. Lmao. I could have done that for $2 at home since all I need is a little more rough sand paper. Ha. And no, it didn't help my brakes at all. They produced very little friction, we're extremely loud and there was even a clicking noise from my drivetrain on my ride home I haven't even diagnosed yet. I just had to write this review. Ha. Should have just told them to screw off and bleed the damn brakes. To me, it's simple. This is a classic big city bike shop that is money hungry. $50 for that is LAUGHABLE. I could take this to my hometown bike shop and for that money they'd do a bleed, drivetrain clean, fork pressurization, frame clean, etc. And after all that, I still need my brakes bled. They didn't do it. Ha. EDIT: Attached is the video of my new wheel sound! I think it's just the dork disk, but still.
