Bike shops fix everything from rusty bike chains to frames bent by the hooves of vengeful, unemployed horses. Spruce up your mechanical steed with this Groupon.

Choose Between Two Options

• $25 for a spring tune-up for one bike (a $60 value)
$45 for a spring tune-up for two bikes (a $120 value)

Bike owners haul two-wheeled transports into the shop, where bike experts recalibrate cycles during a 17-point safety check that takes roughly one hour. Spring tune-ups begin with an adjustment of the brakes and gear cable. Technicians tune and true wheels before applying proper tension. If the bike requires it, the hubs, headset, and bottom bracket are adjusted and tires are given air.
