ALUXX Aluminium Frame

The Giant Fathom E+ 2 features a lightweight ALUXX aluminium hardtail frame with trail-focused geometry, designed to provide stable handling and efficient pedalling on varied off-road terrain.

Its 12x148mm Boost rear thru-axle provides a secure wheel connection, while the oversized OverDrive head tube contributes to front-end stiffness and steering precision.

The frame also features an integrated KSA40 kickstand mount, offering a practical option for riders who use their bike for everyday journeys as well as trail riding.

SR Suntour XCM34 130mm Fork

The SR Suntour XCM34 suspension fork provides 130mm of travel, helping absorb bumps and maintain front-wheel traction on uneven terrain.

Its 34mm stanchions provide a sturdy chassis for trail riding, while the 15x110mm Boost thru-axle helps maintain steering precision through corners and rough sections.

Combined with the hardtail frame, the fork provides front suspension comfort while retaining the direct pedalling feel of a rigid rear triangle.

Giant SyncDrive Pro 3X Motor

The Giant SyncDrive Pro 3X motor delivers up to 100Nm of torque, providing powerful pedal assistance for steep climbs and challenging off-road terrain.

Giant's PedalPlus 6-sensor technology monitors rider input and riding conditions to adjust motor assistance, helping deliver a responsive and natural pedalling experience.

The motor provides support when accelerating, climbing or maintaining momentum over uneven surfaces, allowing riders to tackle demanding routes with less physical effort.

Giant EnergyPak Smart 625Wh Battery

The integrated Giant EnergyPak Smart 625Wh battery provides power for extended assisted rides, with its position inside the down tube helping maintain a balanced centre of gravity.

The battery is designed to work efficiently with the SyncDrive Pro 3X motor, providing consistent assistance across changing terrain.

Using Giant's 4A Smart Charger, the battery can reach approximately 80% charge in under four hours, helping reduce downtime between rides.

Actual riding range will vary depending on terrain, rider weight, assistance level and riding conditions.

Giant RideControl Dash 2

The Giant RideControl Dash 2 combines a full-colour LCD display with integrated controls, allowing riders to monitor ride information and manage motor assistance.

Five support levels provide different amounts of assistance to suit the terrain and riding conditions.

The system also features Smart Assist automatic mode, which uses sensor information to adjust assistance without requiring riders to change support levels manually.

Shimano CUES LinkGlide 10-Speed Drivetrain

The Shimano CUES LinkGlide 1x10-speed drivetrain provides a wide gear range and durable shifting performance for electric mountain biking.

Its 11-48T cassette offers low gearing for steep climbs and suitable ratios for faster trail sections, while the Shadow+ rear derailleur helps reduce chain movement over rough terrain.

Shimano's LinkGlide technology is designed to improve drivetrain durability and deliver smooth gear changes, particularly useful when riding with motor assistance.

Shimano MT200 Hydraulic Disc Brakes

Shimano MT200 hydraulic disc brakes provide reliable stopping power and controlled braking for trail riding and everyday use.

The bike features 180mm rotors front and rear, offering consistent braking performance when descending or riding in changing conditions.

The hydraulic system provides progressive braking control with relatively light lever effort, helping riders manage their speed on loose and uneven surfaces.

Giant XCT 29-Inch Wheelset

The Giant XCT 29-inch wheelset features e-bike-optimised rims with a 25mm internal width, designed to provide durability for off-road riding.

The larger wheel diameter helps maintain momentum and roll over roots, rocks and uneven ground, contributing to stable handling on varied terrain.

Shimano TC500 Boost hubs and stainless steel spokes complete the wheelset, while the tubeless-ready rims provide the option to convert to a compatible tubeless setup.

Maxxis Rekon 29x2.4 Tyres

The Maxxis Rekon 29x2.4 tyres feature a versatile tread pattern designed for trail riding, offering a balance of rolling efficiency and off-road traction.

Their 2.4-inch width provides a useful contact patch for grip and comfort, while the EXO casing adds sidewall protection against cuts and abrasions.

The tyres are well suited to hardpacked trails, loose surfaces and mixed off-road routes.

Trail-Focused Finishing Kit

The Giant Connect TR riser handlebar measures 760mm on size small and 780mm on medium through XXL, providing steering leverage and control on the trails.

A forged aluminium seatpost and Giant ErgoContact Trail saddle provide a straightforward, durable setup for regular riding.

Large platform pedals with 28 pins provide a broad surface for foot support and grip.

Built for Off-Road Adventures

With its ALUXX aluminium frame, 130mm suspension fork, 29-inch wheels and powerful SyncDrive Pro 3X motor, the Giant Fathom E+ 2 is designed for riders looking to explore more challenging off-road routes.

Its combination of Shimano CUES gearing, hydraulic disc brakes and a 625Wh battery makes it a practical choice for trail riding, woodland routes and longer off-road adventures.
