Giant Bicycles (France) – Giant unveiled its new SyncDrive Pro motor technology for E-bikes at a global media event on the island of Corsica, France.

Delivering superior power output for performance-minded E-bike riders, SyncDrive Pro represents the most advanced motor technology in Giant’s latest line of E-bikes. SyncDrive Pro hardware is produced by Yamaha, and the software is programmed by Giant. The result of this partnership is a lightweight and powerful pedal-assist technology that’s tuned to give riders a seamless power boost for performance riding applications.

Superior Power Output:
The new SyncDrive Pro offers five support modes (Eco, Tour*, Active, Sport and Power) and powerful assistance with a maximum support ratio of 360%. This means that, in the “Power” mode, 100% of human torque input offers 360% of pedal-assist power.


To provide a quicker and more direct response to pedaling, both the ISIS BB interface and clutch are updated. A new ratchet mechanism and hollow axle shaft result in faster engagement and a quicker, more positive feel.

High Performance Ride Quality:
For performance-minded riders, this motor offers 80Nm of powerful support up to 120 max rpm in the three upper support modes (Active, Sport, Power). The rider experiences no power loss at higher cadences, 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 also tuned to give quick and direct response to pedaling. It delivers 100% of 80Nm of motor torque in less than 190 milliseconds.


Giant’s flagship Full-E+ 0 SX Pro model offers 160mm of rear travel with its Maestro suspension system. It gives performance-minded trail riders smooth, confident control on rugged terrain.

Lightweight and Compact:
With reduced weight (380 grams lighter compared to the SyncDrive Sport and Life) and reduced volume (13% less volume compared to SyncDrive Sport and Life) this new SyncDrive Pro motor is the ideal candidate for high performance E-bikes. The light and compact motor allows added ground clearance and a more seamless integration with the frame. A hollow axle shaft is used to further reduce weight, and a 128mm ISIS interface BB allows for a narrower Q factor to fit MTB standards.

The SyncDrive Pro will be first available on the Full-E+ SX Pro and Full-E+ Pro full-suspension mountain bike models, available in select markets in February.

* The "Tour" name will be changed to "Basic" for bikes delivered in June.
