Fathom E+ EX 2024

The Giant Fathom E+ Ex 2024 is an aluminium full-power hardtail eMTB built around Giant's in-house SyncDrive Pro2 motor, pitched as a do-it-all entry-to-mid-level full-power hardtail. Headline numbers: 85 Nm of torque, 800 Wh removable Giant EnergyPak battery, 120 mm of front travel, a 66.0 degree head angle and 24.8 kg claimed. There are no curated community quotes on file yet, so this verdict draws on the gold spec sheet and Giant's broader platform context.

Drive system and range. The SyncDrive Pro2 is Giant's own-brand mid-drive unit, built in partnership with Yamaha, producing 85 Nm of torque and a 600 W manufacturer-claimed peak, at a 2.75 kg motor weight. The 800 Wh EnergyPak battery is removable and is one of the largest packs in this class, paired with the 120 mm front-travel hardtail format which keeps frame weight modest. Real-world range on a hardtail 24.8 kg eMTB with 800 Wh is exceptional — expect long all-day rides comfortably within reach on mixed terrain, and 100 km-plus tours feasible in lower assist modes. The trade-off versus Bosch CX or Shimano EP801 is the smaller dealer network for SyncDrive units outside of Giant's own retail channel, though the motor itself has proven reliable across multiple model generations.

Geometry and handling. The Fathom E+ Ex runs five sizes (S, M, L, XL, XXL), with reach progressing from 416 mm (S) through 446 mm (M), 466 mm (L), 481 mm (XL) and topping out at 486 mm (XXL). The head angle is fixed at 66.0 degrees across the range, which is appropriately conservative for a 120 mm trail-leaning hardtail. The 470 mm chainstay is shared across all sizes — long even by hardtail standards — and the wheelbase grows from 1,197 mm (S) to 1,284 mm (XXL). This is a stable, planted geometry profile that will reward steady climbers and tour-style riding, but feel slow to flick into corners compared to shorter-rear-centre rivals.

Build and value. Only the base trim is on file, with the alloy frame, SyncDrive Pro2 motor, EnergyPak 800 battery and Giant's component spec. Price for the UK market is not listed in the gold facts, but Giant's direct-to-shop distribution typically prices this segment well below carbon full-suspension rivals at equivalent motor and battery specs. Buyers should expect a Shimano-leaning groupset and house-brand wheels at this level.

Verdict. The Giant Fathom E+ Ex 2024 makes sense for the rider who wants a high-capacity 800 Wh battery, a robust full-power motor at 85 Nm, conservative trail-friendly geometry and the Giant dealer network behind them, all on a sensibly-priced alloy hardtail platform. Less suitable for buyers who prioritise aggressive trail handling, full-suspension comfort on rougher terrain, or the very latest Bosch CX Gen 5 / Shimano EP801 motor systems.
