GT GRADE BOLT BIKE

The GRADE BOLT is a gravel bike that is perfect for riding on gravel trails as well as for daily commuting in the city. The bike features an aluminum frame, a carbon fork and the Mahle Ebikemotion drive system (X35 motor in the hub and 250 Wh battery).

The bike is extremely versatile and features a triple triangle frame design for maximum comfort and connection of the rear chainstays to the top tube for a smoother and more enjoyable ride on both paved roads and off-road terrain. The "floating" chainstays, specially designed to give the body an optimized shock-damping capacity, allow a better absorption of stresses (about 50% more than a traditional hardtail frame).

As far as the geometry is concerned, the bike features a head tube angle of 71° (69,5° for size S) and a vertical tube angle of 73 and an orientation towards a more sporty and comfortable ride, ideal for those who ride for several kilometers.

The fork, made with tapered tubes, is made of carbon fiber and is prepared for the mounting of fender and rack.

The bike is also equipped with several attachment points, located on the top tube and seat tube, to attach water bottles or bags for bikepacking.

The Mahle Ebikemotion X35 motor, with 250Wh of power and 40 Nm of torque, provides assistance up to a maximum of 25km/h and is positioned in the rear hub. The 250Wh battery, on the other hand, is fully integrated inside the down tube.

To interface with the drive system you can either use the special button on the top tube or take advantage of the dedicated App available for both Android and iOS. The Mahle ebikemotion SLU App connects to the bike via Bluetooth and allows you to keep an eye on all the data relating to the electric drive system.

The wheels are 28 "and are designed to tackle dirt and gravel paths typical of gravel trails and can mount a maximum tread of 42 mm.

The bike has a double crown crankset, 10-speed transmission, Shimano GRX 400 disc brakes and is compatible with a telescopic seat post. Racing handlebars with the traditional fold.
