Orbea Wild ST H20

The Wild ST H20 is Orbea's option for riders who want a full-power e-MTB built for climbing hard and covering technical trail all day, without moving into the longer-travel Wild's more descent-biased setup. It pairs a 150mm, full-29in alloy chassis with a genuinely capable spec list: a strong motor, a large battery, proper trail suspension and brakes with real stopping power. That combination makes it a sensible pick for anyone whose rides involve a lot of climbing and a lot of ground covered, rather than someone chasing the steepest, roughest descents.

Full-power climbing without the longer-travel compromise

At the centre of the bike is a Bosch Performance Line CX motor, matched to a PowerTube battery rated at 750Wh, a genuinely large capacity that gives you plenty of runway for long days with a lot of vertical gain. A motor's headline output can depend partly on firmware settings, so treat any figure you see quoted as a general guide rather than a fixed guarantee on every individual bike. Orbea doesn't currently list this exact version in its UK catalogue, so you're more likely to find it through individual retailer offers than through Orbea's own site, which is normal and doesn't change what the bike actually is.

Suspension, brakes and a mixed-tier drivetrain

Travel is 150mm at both ends, delivered by a Fox 36 AWL HD Sport fork up front and a Fox Float Performance shock at the rear, a pairing built for technical trail riding rather than bike-park abuse. Stopping power comes from Shimano's M6120 four-piston brakes, which give you the kind of consistent, strong braking you want when carrying the extra weight of a motor and a big battery down a descent. The drivetrain is worth understanding properly before you buy: it's a 12-speed, 10-51 tooth cassette with a Shimano SLX rear derailleur, but paired with a Deore-level shifter rather than a full SLX groupset. That's a sensible way to keep the price down without touching the parts that matter most for shifting under load on a climb, but it's not the same as an all-SLX build, and it's worth knowing that distinction rather than assuming a single component tier throughout.

Choosing your size

Orbea's published height guidance overlaps between adjacent sizes, so it's worth checking the specific ranges for your height rather than assuming you already know which one fits. Dropper post travel and stem length both scale with frame size too, giving taller riders more post travel to play with and shorter riders a shorter stem for quicker steering. One detail worth flagging if you're looking at an XL: Orbea's original 2025 geometry gives that frame a 460mm seat tube, while the geometry chart attached to a 2026-labelled UK offer states 450mm instead. It's a small difference, but if your minimum saddle height is already tight on an XL, it's worth checking which figure applies to the specific bike you're considering rather than assuming the two charts agree.

Understanding the battery and any range claims

The battery you get as standard is the 750Wh PowerTube, with no range extender fitted to this build. Orbea does list a separate 250Wh PowerMore range extender as an accessory, which is worth knowing about if you regularly ride further than a single charge comfortably covers, but it's an optional extra you fit yourself, not part of what the bike ships with. You may also see individual retailer listings quoting a wide range estimate, sometimes as broad as 30 to 160 miles. That kind of spread reflects the difference between the most efficient assist mode on flat ground and the most demanding mode on steep technical terrain, so treat it as the outer limits of what's possible rather than a promise of what you'll get on a typical ride.

Wild ST, Wild TR and the longer-travel Wild

It's easy to get the Wild family mixed up, and UK listings don't always help: some reuse generic Wild copy that describes 170mm of travel before getting to the ST's actual 150mm figure. The Wild ST H20 is not the same bike as the Wild TR H20, which has its own frame designation and standard build; a similar name and similar trail intentions don't make their frames or parts interchangeable, so compare the actual equipment on any TR listing rather than assuming it matches this bike. It's also worth keeping this ST version separate from the standard Wild H20, which is the longer-travel, more descent-focused 170mm bike built around a different fork. If what you want is climbing efficiency and all-day trail capability rather than the most aggressive way down a hill, the ST is the one built for that job.

Set up this way, it's a bike best suited to riders who measure a good ride by how much climbing they got through rather than by how steep the way down was, a genuine long-day trail companion with the motor and battery to make that kind of riding realistic rather than exhausting.
