Bottom Line Bottom Line

Critical Cycles' distinctive fixie style includes BMX-type handlebars for the adventurous rider and comes in more than 10 different color combinations. Customers rave that it's easily customizable with upgrades. A versatile flip-flop hub and brand-name components all add up to a valuable single-speed package.


Not too twitchy. The Critical Cycles Single Speed Road Bike receives very positive feedback for performance at, where it's currently the No. 2 best-seller behind the Takara Kabuto Single Speed Road Bike (Est. $200). A hand-built steel track frame with bar-spin clearance and flat-top tube makes this bike a standout in its price range at where Pete Prebus notes, "the handling of the bike was quick but still comfortable -- not too twitchy."

ProsSolid components, Flip-flop hub, BMX handlebarsConsNo front brake, A bit heavy, Rims could be stronger

A flip-flop hub allows riders to easily switch from a fixed-gear mode, in which the pedals move with the rear wheels, to standard single-speed for the ability to cruise. Distinct straight BMX-type handlebars are a hit among those looking to try freestyle tricks and stunts. Other reviewers say they prefer the straight handlebars for city riding.

Some users dislike that the Critical has only a rear brake. Prebus says the stock brake pads wear out quickly, probably because there's only a rear brake and "the pads' material was also low quality."

The Single Speed Road Bike's gear ratio of 48:16 pedal crank cog to rear cog is pretty high for climbing hills but cruises along the flats comfortably, making it great for city commutes. Prebus calls it "a quick bike, like you would expect from a road-style track bike," but says if you live in a hilly area, you may want to change the chainring or rear cog size.


Stiff seat. Several owners describe the seat as stiff but say it provides comfortable stability, adding that they like it overall. While's Prebus is impressed with the Critical's BMX-style handlebars, he finds the toe grips to be "a little cumbersome" and eventually removes them.


Strong, TIG-welded steel frame. Reviewers like that the Single Speed Road Bike's bottom bracket comes sealed against moisture and dirt, and although owners say the Promax brakes are a nice touch, the pads need to be switched out sooner than later. Stock tires also receive kudos, with some riders calling them "really good quality."

Critical Cycles describes the deep V, double-walled rims as adding "strength and rigidity," but several users say they seem weak. At this price point, this feature is most likely more for aesthetics than performance.
