The Giant Fathom E+ is designed to give you easy, predictable support when you’re tackling off-road climbs or linking together woodland trails. The SyncDrive Sport motor delivers up to 85Nm of torque, and the assistance comes in smoothly as you put power through the pedals. It feels natural and steady, especially when the gradient changes or you’re picking your way up a technical section.
Its ALUXX aluminium frame uses trail-friendly geometry that centres your weight well, helping you feel planted on loose surfaces. The SR Suntour XCR34 fork offers 130mm of travel to soften the feel of roots, rocks and trail chatter, giving you a bit more confidence when the terrain turns rough without pushing the bike into more extreme territory.
The fully integrated EnergyPak Smart 750Wh battery gives you solid range for longer days out. Using the Fast Charger, you can reach 80% charge in around two and a half hours, making it easy to top up before a ride or during a break. The RideControl Dash 2 display keeps your ride data clear, with high-angle visibility that’s easy to read in changing light.
Shimano’s CUES 10-speed drivetrain handles the shifting, paired with a wide-range 11–48T cassette to help you manage steep climbs without grinding. The Shimano MT200 hydraulic disc brakes provide steady stopping power with simple maintenance and a familiar lever feel.
Strong 29" Giant XCT wheels are e-bike optimised and come tubeless ready, giving you better puncture protection and the option to run lower tyre pressures. Maxxis Rekon 2.4" tyres offer balanced grip and rolling speed across mixed trail conditions. A Contact Switch Core dropper post rounds things out, helping you shift your weight easily on descents.
Altogether, the Fathom E+ offers supportive power, confident handling and a reliable spec for riders who want to explore off-road terrain with a bit more ease and range, without overstating its intentions. If you’d like this adapted for a shorter format or category page, I can do that too.
