They say you never forget how to ride a bike, but the ride itself can still get plenty rusty -- make yours look and move like new again with today's deal: Score one complete bike tune-up (this includes the cleaning, adjusting, and tuning of each and every part of your bicycle) from Bike Boom for $35 (regularly $70). Located on Highland Avenue just off Davis Square, this popular bike shop earned "Best of the New" honors in 2011 from The Boston Globe. Get your two-wheeler into gear with a component cleaning and lubing; brake and shifter adjustments; a thorough frame and chain cleaning; tire inflation; and a free part installation (when necessary). With your newly spiffed up ride, you'll be passing cars again in no time. Want more? Check out Bike Boom on Facebook.
