Responsive hard tail handling: Frame is designed for and fitted with a 120mm suspension fork for smooth off-road control.

SyncDrive Pro: SyncDrive Pro is tuned to deliver a powerful, performance-oriented riding style. The lightweight and compact motor is updated for 2019 with the possibility to tune it just the way the rider wants. With a predictable output that reacts to human input, the motor produces linear support to give you more control while riding.

The 80Nm power output offers superior torque and support ratios up to 360 percent. This means that, in the Power mode, 100 percent of human torque input offers 360 percent pedal-assist. This offers more freedom in how the E-bike rides and handles.

Made for performance minded riders, this motor offers 80Nm of powerful support with up to 120 max rpm in the three upper support modes (Active, Sport, Power). The rider experiences no power loss while reaching higher levels of cadence, which makes steep climbs more accessible and comfortable. At the two entry support modes, the rider is rewarded with 110 max rpm and 80Nm of motor torque.

SyncDrive Pro is tuned to give quick and direct response to pedaling, delivering 100% of motor torque in less than 190 milliseconds. Both the ISIS bottom bracket interface and clutch have been updated to provide a quicker, more direct response. Backlash of the ratchet mechanism is reduced by one third and a hollow axle shaft creates a quicker, more direct response. With the narrowest Q-factor of 168mm, SyncDrive Pro makes performance riding even more natural.


SUPERIOR POWER OUTPUT: Giant’s most powerful motor technology with a massive 80Nm of torque for steep climbs and a 360 percent support ratio.

TUNEABLE PERFORMANCE: The rider can adjust the support ratios for a more dynamic ride experience that matches every rider’s individual needs.

EASY HANDLING: With only a few button controls and indicators, it offers simple control of your E-bike

PedalPlus 4: Giant’s PedalPlus 4-sensor technology precisely measures the amount of force a rider is applying to the pedals so that the motor delivers a seamless power boost. The system uses speed and torque sensors along with motor and pedal rotation sensors to produce even power across the entire gear range. The result is predictable power that feels totally natural in any gear and makes riding the bike feel smooth and powerful on all types of terrain.

TORQUE SENSOR TECHNOLOGY: The torque sensor reacts to pedal pressure. The more pressure you apply to the pedals, the more support you get from the motor. It precisely measures this force so that the motor can deliver a seamless power boost.

SPEED SENSOR TECHNOLOGY:The speed sensor works independently from the pressure you are putting on the pedals. It precisely measures the speed the rider is traveling.

MOTOR AND PEDAL ROTATION SENSORS: Allows the motor to run as smoothly and seamlessly as possible

NATURAL FEELING: The torque sensor measures the amount of power the rider is applying to the pedals so that the motor can replicate the natural riding style, adding assistance when needed.

EFFICIENCY: The PedalPlus 4-sensor technology maximises energy efficiency for both the rider and the battery system.

Instant Support: The combination of the sensor technology and the instantaneous response of the SyncDrive motor creates a smooth and powerful riding experience.

Downtube EnergyPak: Future-proof with the new down tube EnergyPak. This updated EnergyPak is mounted in the down tube of our E-bikes. The biggest difference between the side release and top pull EnergyPak is a more minimalist down tube design. This makes it look more integrated and streamlined with the rest of the E-bike frame.

With an aluminium casing, a moulded bottom protector and a double lock feature, this Down tube EnergyPak can handle rough rides. It is able to communicate with the charger and has highly innovative cells that are individually controlled by the smart charger. This gives the Down tube EnergyPak a longer lifetime.

Heat build-up is managed internally by having double the space between cells giving more temperature control. This makes it safer to handle.

This EnergyPak is also easy to access. With one turn of a key, it releases from the down tube and is ready to charge. The EnergyPak is equipped with highly innovative cells that charge to more than 60% within 90 minutes with 6A charger.


INTEGRATED DESIGN: The Down tube EnergyPak offers a well-established, integrated design with more minimalist down tube profile.

EASY TO OPERATE: Easy and safe to handle, the Down tube EnergyPak has two locks so it can be easily removed without any hassle.
