Bell Citi

The Bell Citi bike helmet is a favorite of reviewers, and it's often recommended for commuters. With 16 vents, reviewers say it is well ventilated, and a small visor helps reduce road glare. The Bell Citi also has a round, smooth profile, with few pointy edges that can snag in the event of a crash. The Citi bike helmet does well not only in government impact tests, but also in independent impact tests. The helmet comes in only one size, so it may not fit larger or smaller heads, but it does come in a variety of colors -- including bright yellow or orange for visibility. Most reviewers are impressed with the Bell Citi, but several have complaints about the chin straps. Some say the air whistles noisily through the chin straps and vents, and another reviewer says the straps do not stay put easily. If you prefer a sportier-looking helmet, the Giro Indicator (*Est. $40) also gets good reviews.

The Bell Citi receives reviews from both experts and consumers. The most comprehensive review comes from ConsumerReports.org, which tests the helmet on impact absorption, fit and ventilation. However, this test is several years old. Other reviews from sources like CommuteByBike.com or Time Out New York are helpful, but they are less detailed and not comparative. Almost 30 owners at Amazon.com and Buzzillions.com rate the Bell Citi, with a focus on ventilation and comfort.
