This Defy is faster and more fun than before, but it doesn’t forgo its signature forgiving ride quality.
BikeRadarIt almost perfectly balances performance and comfort and the spec list at this price point is almost unbeatable.
Cycling WeeklyGiant has struck an excellent balance to keep the Defy confident without it becoming dull.
CyclistGiant’s revamped carbon fiber Defy Advanced ticks an awful lot of boxes.

Our Road Bike of the Year winner for 2024
Balanced handling
Comfortable
Stable but still quick
Tyres lack sense of speed but are very grippy
Apr 2024 · Martin Staffa
Lightweight, comfortable, and fast. The 5th generation of the GIANT Defy promises all this and more. Can the endurance bike deliver, or is its beauty just skin deep?
Racy, stylish, and modern look
Efficient acceleration
Excellent climber
High fun factor
Lack of attention to some small details like the stem bolts
Bar tape is too short
Sept 2023 · John Stevenson
Excellent do-almost-everything endurance bike; practically the type specimen for the genre
Perfect handling for all-day riding
Versatile; unfazed by dirt roads and easier trails
12-speed Shimano 105 Di2 is excellent and massively tunable
Set up for tubeless, just add sealant
Heavy wheels
Even wider gear range would be nice
Sept 2023 · James Huang
Giant’s fifth-generation premium carbon fiber endurance road bike, updated with a lighter chassis, additional tire clearance, and a more refined ride quality.
Impressively lightweight
Composed ride quality
Quick handling
Some semblance of cockpit customization
Looks brilliant.
Composed-but-not-cushy ride quality
Handling is arguably too quick
Questionable wheelset spec
Still a proprietary stem.
Sept 2023 · Troy Templin
The Giant Defy is for going longer. It’s for climbing higher, riding faster, and doing it all with confidence and smooth control.
Jul 2020 · James Bracey
Giant's Defy moves into more versatile territory with an updated frame and bigger tyre volume

Giant’s latest Defy is future-proof, versatile, fast and far less expensive than equivalently specced alternatives
Fast
32mm tyres
Predictable handling
Well priced
Slightly heavy
Fiddly seatpost bolt

I love the bike in every way. Unfortunately, i feel i made a mistake with the size. I should have bought the XS. Short legs longer torso would have su
Fast, light and very agile. Looks great.
Nothing to dislike.
