GIANT FATHOM E+ 0 PRO
Ride rough roads, paths or single tracks with power and control. This new off-road e-bike helps you conquer hills and challenging terrain in a whole new way.
Giant Hybrid Cycling technology. With RideControl, switch on the electric drive and select the desired power level. As soon as you start pedalling, you activate the PedalPlus sensors that transmit information to the control unit. This ‘brain’ of the entire system quickly sends a request for an adequate amount of energy to the EnergyPak. Subsequently, the energy is transferred to the SyncDrive, which starts to help you pedal immediately and smoothly.
High performance and long range. The Yamaha SyncDrive Pro centre motor delivers high torque of 80Nm and support up to 360%. The fully integrated Giant EnergyPak Smart lithium battery offers a capacity of 500Wh. Ultra-fast charging is made possible by the 6A Smart Charger, which can charge 100% in 3 hours and 40 minutes; for a fully discharged 500Wh battery, 80% in just 2 hours and 20 minutes.
Smart Assist automatic mode. In addition tot he 5 driving modes that you select manually, you also have Smart Assist mode, which automatically adjusts the amount of motor support so you don't have to worry about it. Due to this function, the 6-sensor PedalPlus technology is used, which adds an acceleration sensor and an inclination sensor to the four basic sensors.

Giant SyncDrive center 250 W electric motors are the result of the close cooperation of Giant with the leader in electric motors – Yamaha, guaranteeing their high quality and reliability.
Despite the compact size, they deliver a high torque of up to 80 Nm, which shows just as soon as you start your ride. Their immediate response is also important – the motor starts running as soon as you begin to pedal. This quick response will not only help you when accelerating, but also truly comes in handy in many steep climbs, when you rely on the e-bike to "pull" you up.
The SyncDrive motors produce proportional and linear support, and their operation is predictable, smooth and quiet, simply a natural boost to your own energy.
