With the Stormguard, Giant presents an e-bike that has been specially designed as an SUV. Equipped with a suspension luggage rack, this bike is designed to be a comfortable alternative to traditional touring bikes and also impresses off the beaten track.

High weight, a sturdy carrier, mountain bike tyres and a banana swingarm-style rear triangle: the Giant Stormguard was one of the very first bikes on the market to be developed specifically as an SUV, making it the pioneer of an entire category.

Here, the development department has thought much more deeply than simply equipping an e-MTB with a rack and mudguards. Everything on the Giant is specially designed for adventure, riding comfort and travelling. Fittingly, the Stormguard is also available in a version with continuously variable Enviolo gears and belt. For this test, we focussed on the sportier version with derailleur gears and Fox suspension.

Globetrotter with suspension luxury

The consistent focus on cycle touring also makes the Giant somewhat special in other respects. The pannier rack attached to the main frame is the most striking feature of the special concept. It has the advantage that the Giant's suspension remains undiminished even when loaded. All other test candidates in our E-SUV test have to be converted to rucksacks instead of panniers for serious off-road use. However, the expansive design requires agility when getting on and off the bike and only carries a maximum of 15 kilograms. Neither is ideal for everyday use. The Syncdrive Pro 2 drive, on the other hand, is convincing even when commuting. Giant has taken the powerful mid-motor directly from its own E-MTBs.

The Giant performs well off-road, but can't hold a candle to the MTB competition with its touring geometry and rather short suspension travel. But it doesn't have to, because Giant still has the Stance E+ SUV with mountain bike geometry in the programme (test here). However, the bike shows its strengths when travelling and on extended tours. Here, the upright riding position and neutral handling are a pleasure. The steering damper costs a little agility in handling, but should improve the bike's directional stability when loaded. The Syncdrive Pro 2 motor pushes comfortably and is usually quite quiet. Thanks to the 800 battery, the bike has a long range. However, the haptic feedback of the control buttons and the information density of the central display could be a little better. There is no sat nav function, for example.

MYBIKE review of the Giant Stormguard E+ 1

Strengths

  • High touring and travelling comfort
  • High-quality equipment
  • Suspension performance with load

Weaknesses

  • Specialist with limited suitability for everyday use
  • Luggage carrier only carries 15 kilograms

The MYBIKE conclusion

Giants Stormguard performs particularly well on long tours and journeys and masters rough trails with a high level of comfort. Thanks to its moderate geometry, the heavy Stormguard is easy to ride, but with its limited suspension travel, it is not a proven trail pro. The high-quality equipment, from the Fox suspension to the expensive Cues gears, is impressive. - Adrian Kaether, Test Manager MYBIKE

Adrian Kaether's favourite thing to do is ride mountain bikes on bumpy enduro trails. The tech expert and bike tester knows all about Newton metres and watt hours, high and low-speed damping. As test manager at MYBIKE, Adrian also likes to think outside the box and tests cargo bikes and step-through bikes as well as the latest (e-)MTBs.
