The bike is from around 2012, but everything’s in excellent shape, fully tuned up, and ready to go. It comes with the Di2 charger as well.
This was Giant’s top-tier Defy model back then—great for longer rides thanks to its endurance geometry, but still quick and responsive when you need it.
Size is Medium, ideal for riders roughly 5’8” to 6’ tall.
Original MSRP was $4,550 (plus tax).
I collect and restore vintage bikes, and I enjoy bringing gently used more recent models back to like-new condition. It’s always rewarding to see them back on the road, helping people stay active and reduce car use. I also offer repairs and tune-ups for the bikes I sell - please check out my Instagram - sfbikemarket.
I’m a great resource if your bike was made between 1970–2015, since I have those harder -to-find parts from Shimano, SRAM, and Campagnolo 7–10 speed drivetrains, as well as appropriate and matching replacement wheels.
My tiny “one-man-orchestra” operation is on Treasure Island, SF. It’s easy to get here - Bus 25 runs every 20 minutes from the Salesforce Terminal and in 10–15 minutes drops you off a block away from my place. There’s also a $5 ferry from the Embarcadero, a fun option if you want to explore the island or visit Mersea for food and views and don’t mind walking a little.
Oaklanders and "Berkelenians" might need to add a Bart ride into the city first, but have the luxury of riding their newly acquired bike down the bay bridge back home.
