GT eGrade Amp Electric Gravel Bike
Since its inception, Grade has continuously pushed the boundaries of adventure riding. As the pioneering carbon gravel bike, it made a remarkable impact upon its launch, receiving numerous industry accolades. In 2019, the introduction of our floating Triple Triangle™ seatstays propelled the bike to new heights, earning prestigious distinctions such as Gravel Bike of the Year from Bike Radar and Bike Rumor. Never satisfied with past achievements, Grade has undergone further enhancements. The latest iteration features refined geometry, expanded tire clearance, internal cable routing, and ample frame protection, ensuring it is more capable than ever for off-road adventures.
