Hybrid Cycling technology combines the natural feel of traditional cycling with intelligent electrical support. Hybrid Cycling works with precise sensors that monitor pedaling power, cadence and speed. Based on this data, the motor delivers exactly the power the rider needs at any given moment. The result is a natural, smooth and quiet ride, without jerky reactions or a feeling of "engine push". It also contributes to better efficiency and longer range because the system only uses battery power when it is actually needed. This makes driving not only more comfortable, but also more economical.
All SyncDrive engines use Smart Assist technology, which adapts engine assistance to the needs of the driver. It is the only system in the e-bike category that uses both rider data and feedback from the field to determine the ideal level of engine support, using information from multiple sensors. It delivers a smooth and natural ride with enough power for the riding situation, while saving power when less is needed.


ALUXX SL Aluminum is a high-end aluminum alloy developed by GIANT for the production of lightweight and high-strength electric bike frames. It offers lower weight, higher strength and better stiffness, which directly translates into riding performance.
ALUXX SL frames are manufactured using advanced hydroforming, which allows the individual tubes to be precisely shaped according to their load. This makes the frames light where it's possible and strong where it's needed. The result is an optimal balance between strength, comfort and weight. The great advantage of this alloy is also its high resistance to material fatigue and corrosion, which guarantees a long frame life even under intensive use.
The GIANT E-Lock System is a modern electronic security system designed for GIANT electric bicycles that significantly increases protection against theft. The system is fully integrated into the electronics of the e-bike and connected to the RideControl / Giant E-Bike App. When E-Lock is activated, the drive system is electronically locked so that the e-bike cannot be used or ridden without the owner's authorisation. Unlocking is done simply via an app on a smartphone or via a paired display.

GIANT Fathom E+ - sporty hardtail e-MTB for trail and everyday trips
The GIANT Fathom E+ is a sporty hardtail mountain e-bike that combines the performance of a trail bike with modern electric assistance. It is the ideal choice for riders who want to tackle forest trails, more technical terrain and longer trips without unnecessary compromise.
It brings a host of improvements. First and foremost, it's an all-new frame with a modern, sporty design and geometry. Next is the powerful SyncDrive Pro 2 motor and the EnergyPak Smart 750 Wh battery. The suspension fork travel has been increased to 130 mm.
At the heart of the bike is the powerful Giant SyncDrive Pro 2 mid-motor, which provides smooth and natural pedaling assistance. Thanks to sensitive power delivery, it helps you climb climbs efficiently and maintain a steady pace even on longer trails. The integrated 750Wh EnergyPak battery is neatly recessed into the frame and offers ample range for all-day rides.
The lightweight and durable ALUXX aluminium frame with modern trail geometry ensures confidence and stability on the terrain. A front suspension fork with higher travel effectively dampens bumps and increases comfort when riding on rocky or rutted roads. Large 29" wheels improve off-road handling and contribute to a smooth ride.
The e-bike is equipped with reliable components, including hydraulic disc brakes for confident braking in all conditions and clear assistance controls directly on the handlebars. Thanks to the simple hardtail design, the Fathom E+ is low-maintenance yet highly versatile.
The GIANT Fathom E+ is a great choice for sporty riders looking for a powerful and reliable mountain e-bike for active outdoor riding and everyday commuting.
