Customer Reviews

5 / 5 stars
All Terrain Cycles

The new 2015 Defy road bike was put to the test by the editors at BikeRadar and came away with a strong rating of 4.5 (out of 5) stars. Calling the Defy “a bike you can ride all day on, commute on in comfort, race on, and have fun on,” the review highlighted some of the key changes to the frame and parts kit for 2015. “It’s a fine, almost unbeatable balance of handling, speed and performance, and our tester’s ultra-experienced posterior reckons this Giant is more comfortable than its predecessor—smoother over rutted roads and perfect for long days. You can even squeeze in 28mm rubber if you want extra plushness.” Summing it up, BikeRadar offered this verdict: “Ace refresh of a beloved steed, tweaking comfort and value for the better without tampering with what made it great in the first place.”
