More Dirt, Less Hurt.
The GT Grade Bolt is the sporty e-gravel bike of the Power Series, with drop bar and Shimano GRX.
Model description
The Grade Bolt combines the proven EnduRoad geometry and the aluminium frame in Triple Triangle design with the light MAHLE X35+ hub motor. The motor assists naturally and subtly, so climbs and headwinds become easier without the bike losing its sporty character. The battery is hidden in the down tube.
The Shimano GRX 2x10 drivetrain offers close ratios on tarmac and enough range for steep gravel ramps. The hydraulic GRX disc brakes give you full control, while the Floating Stays and 42 mm WTB Nano Comp tyres absorb bumps on rough roads.
What it's for
