While the invention of the wheel was perhaps mankind’s greatest innovation, it wasn’t until the invention of the second wheel that man was finally able to ride his innovation to work. Pamper your bi-wheeled wonder with today’s Groupon: for $22, you get a basic bike tune-up (a $45 value) at Tri-Sport Bicycles, across from Woodward Park.

Tri-Sport Bicycles is a fully equipped bicycle store and repair shop staffed by bikethusiastic staffers who know how to make any rust-riddled beater ride as smoothly as a hoverboard. The basic tune-up ($45) begins with a thorough wipe down and lubing. Surgical adjustments are made to the tension of the brakes, ensuring riders can stop on a dime, pick it up, and buy a Chiclet without ever dismounting. Derailleurs are inspected and rebuffed to transform sticky gears into smooth shifters. Wobbly wheels undergo a truing process to increase pedal-pumping efficiency and ease momentum retention.

Boasting their own company bike team, the fearless owners and employees at Tri-Sport understand what makes a bicycle tick. The staff naturally sympathizes with the constantly roller-coasting emotions of modern bike riding, facing a barrage of potholes, glass shards, and open car doors every day. Without proper attention and regular checkups, your bike’s life could become jeopardized by something as simple as passing an open manhole.

Tune-up does not include replacement parts.
