Bontrager Line Pro OCLV Carbon

Handlebar

The handlebar and stem are where your hands steer the bike. Their width and length set how upright or stretched out you sit.

OCLV Mountain Carbon

Frame

The frame is the bike's backbone: every other part is fixed to it. Its material and shape decide its weight and how it feels to ride.

RockShox Vivid Ultimate

Rear shock

The rear shock lets the back wheel move over bumps. Its travel is how far the rear wheel can move; it is tuned to the rider's weight.

RockShox ZEB Ultimate

Fork

The fork holds the front wheel. A suspension fork absorbs bumps at the front; its travel is how far it can compress.

SRAM Maven Silver

Brakes

Brakes slow the bike. Disc brakes squeeze a rotor fixed to the wheel hub; rim brakes squeeze the wheel rim itself.

SRAM X0 Eagle AXS T-Type

Drivetrain

The drivetrain turns your pedalling into motion: the cranks, the chain, the cassette and the derailleur that changes gear.

Bontrager Galbraith/Brevard RSL SE

Tyres

Tyres are the bike's only contact with the ground. Their width and tread decide grip, comfort and rolling speed.

TQ HPR60

Motor

The motor adds its power to the rider's effort. It sits either at the cranks or in the rear wheel hub; its torque, in newton-metres, tells how hard it can push on a climb.

Battery

The battery stores the energy the motor uses. Its capacity is given in watt-hours (Wh); how far it lasts depends on the rider, the terrain and the assist level.
