More pedaling power means more fun on the trail. That’s the idea behind the new Fathom E+ and Fathom E+ EX, two new E-MTBs that blend modern MTB design with powerful E-bike technologies to give motivated off-road riders more of what they love.

Both are built on a lightweight aluminum hardtail frame that’s totally reengineered from the previous generation. New geometry, including a slacker head angle, results in more control and confident handling on challenging trails. Add in a smooth suspension fork with 130mm of travel and stable 29-inch wheels, and the result is greater efficiency and a smoother ride quality on off-road terrain.

These new E-MTBs give off-road enthusiasts a whole new way to take charge of their riding experience. Whether you’re ripping laps on your local trails, or embarking on a multi-day trek, you can make the climbs go by faster and have more time to enjoy the best parts of the ride.

SyncDrive Motor

Getting up to speed and maintaining momentum is now easier than ever. Your pedaling power is backed by Giant’s proven SyncDrive motor, which helps you climb faster, accelerate quicker, and extend your ride beyond the usual limitations. Tuned to deliver up to 85Nm of torque with a support ratio of up to 400 percent, both the SyncDrive Pro and SyncDrive Sport motors offer instant engagement and a smooth, natural feel.
