Details

Every trail, every steep climb, every thrilling descent. Tested and developed by Giant's E-bike enduro pros, this updated trail ripper gives you the power to enjoy the best parts of the ride again and again.

A 29-inch front wheel and 27.5-inch rear wheel work together to offer superior handling and agility on technical terrain. The updated frameset features new geometry with a shorter rear end and longer reach. New control units include RideControl Go, which is integrated into the top tube, and RideControl Ergo 3, attached to the handlebar near the grip. A new flip chip feature lets you adjust frame geometry for riding style and terrain.
