E-Bike Motors

Giant E-Bikes are built around powerful, reliable motors designed to elevate your cycling experience, no matter your chosen path. But what exactly makes these motors stand out? Let's delve into the key factors that define Giant's industry-leading E-Bike motor technology, the perfect companion for any electric journey – from thrilling electric road rides to smooth electric city commutes and heart-pumping electric mountain escapes.

Sustainable Torque

Torque, measured in Newton meters (Nm), signifies a motor's strength – crucial for tackling hills and accelerating effortlessly. Giant's latest central E-Bike motors are: SyncDrive Core 55Nm, SyncDrive Sport 2 75Nm and SyncDrive Pro 2 85Nm. In each case, this figure is a sustainable torque level. This means that our motors can consistently deliver their maximum torque, unlike some competitors whose peak torque drops significantly after a few seconds.

With Giant E-Bike systems, you conquer climbs with unwavering torque throughout. While excessive torque can cause wheel spin, our 85Nm sweet spot offers optimal performance.

Customise Your Ride

Assistance levels dictates how much power the motor provides relative to your pedalling effort, typically expressed as a percentage.

For instance, if you the rider generates 150 Watts the motor multiplies this and the output would be -

  • In a 100% mode, the motor outputs 150 Watts
  • In a 200% mode, the motor outputs 300 Watts
  • In a 300% mode, the motor outputs 450 Watts
  • In a 400% mode, the motor outputs 600 Watts

The high power outputs of Giant E-Bikes can take the sting out of any terrain. Each bike features 5 pre-set modes ranging from 50% up to 400% assistance, easily adjustable with the RideControl app. The maximum assistance for our motor is - SyncDrive Core 300%, SyncDrive Sport 2 400%, SyncDrive Pro 2 400%.

If 50% as a minimum isn’t enough then no problem, increase it so the bike does more of the hard work in every mode. On the flip side, if 400% is too much for you and you want more of a workout out then reduce it so you have 5 separate modes that work for you and how you want to ride.

Smart Assist

Every Giant E-Bike has a unique 6th mode called Smart Assist. This is the default setting when you switch on the E-Bike, in this mode the bike works out which mode you need to be in automatically.

In any of the regular 5 modes, 4 sensors are monitoring what’s going on.

  • Bike speed
  • Internal motor speed
  • Rider input in Watts
  • Rider’s pedalling rate known as cadence

In Smart Assist two additional sensors come online.

  • An inclinometer to detect if you are going up or down a steep hill or anywhere in between
  • An accelerometer to get a real feel for how you are riding

With all 6 sensors feeding back to the brains of the system, the motor gives the right amount of assistance, instantaniously based on how and where you are riding. This changes constantly based on the terrain or what the rider is doing. Smart Assist takes the guesswork out of mode selection, all you have to do is pedal but don’t forget you still need to change gear.

Best-in-Class Power

Power, measured in Watts (W), fuels the motor's ability to deliver torque. Giant motors boast high power outputs across the board, with the high-performance SyncDrive Sport 2 and Pro 2 motors reaching well over 600 Watts.

This translates to exceptional responsiveness in high-assistance modes. With such potent power, we can confidently offer 400% assistance for unmatched performance.

Advanced Motor Tuning, SyncDrive Pro 2 Exclusives

SyncDrive Pro 2 takes customisation to a whole new level. Beyond the standard assistance level adjustments, this motor allows you to fine-tune -

  • Torque levels, adjustable from 20Nm to 85Nm, creating unique personalities for each riding mode.
  • Launch control adjusts how quickly the power and torque are delivered, with 7 levels to select, the torque “OOMPH” can kick start in a fraction of a second. For instance, Level 1 kicks in within 2.5 second and Level 7 in 0.19 seconds. For some riders, it might be too quick, so adjust the assistance and you can select the mode. Customise the modes to suit your riding style, Giant E-Bike systems offer the ultimate personalisation for your ride.

Giant E-Bike motors offer a winning combination of high performance, adjustability and user-friendliness. Explore the possibilities and discover the perfect E-Bike for the ultimate ride.
