Orbea Wild TR M20

The Wild TR M20 sits at the sharp end of Orbea's electric trail range: a carbon-framed, 150mm-travel machine aimed at riders who want proper climbing assistance without giving up a bike that's genuinely capable and playful once you point it downhill. If your rides tend to involve a testing climb followed by a technical descent, this is built to make that pairing feel realistic rather than exhausting, and the specification backs that ambition up rather than just promising it.

Bosch power and a fitted 750Wh battery

The motor is a Bosch Performance Line CX Gen 5, and Orbea states a maximum of 120Nm of torque and 750W of power. That's a peak figure rather than an ordinary-use promise, so treat it as the ceiling the system can reach under load rather than what you'll feel on every climb, but it still tells you this is a serious, full-power trail motor rather than a lighter-assist compromise. Power comes from a 750Wh Bosch PowerTube battery built into the frame, charged with the bundled 4A charger; that's a genuinely useful detail because Orbea's alloy Wild TR H20 only gets a 2A charger, so the M20 tops up noticeably quicker between rides. No manufacturer-stated range or riding-time figure comes with this build, so it's worth judging battery adequacy by that 750Wh capacity and the terrain you ride rather than by any advertised number of miles.

If you regularly ride further than one charge comfortably covers, Orbea's configurator lists an optional Bosch PowerMore 250Wh extender, which takes combined nominal capacity up to 1000Wh. That's a useful upgrade path rather than something fitted as standard, and it's not a distance claim either, just more stored energy for the same motor to draw on. The standard bike also comes with Bosch's System Controller and Mini Remote rather than the fancier Kiox 400C display, which is a paid configurator option; if on-bar navigation or the Kiox's USB-C charging port matters to you, check whether a particular offer includes it before assuming it's fitted.

What the carbon frame buys you over the alloy Wild TR H20

Both the M20 and the alloy Wild TR H20 share the same 150mm-travel intent and the same fitted 750Wh Bosch system, so the choice between them comes down to frame material and the components built around it. The M20's Orbea OMR TR carbon frame is paired with a FOX 36 Performance GRIP fork and a FOX FLOAT Performance 2-position-adjust shock, both specified at 150mm, while the H20 gets a RockShox Psylo Silver RC fork instead. Shifting runs through a Shimano Deore M7200 rear derailleur and shifter with a wide-range 10-51T cassette, and braking is handled by Shimano MT420 hydraulic discs paired with 203mm Galfer Wave rotors front and rear, plenty of stopping power for a bike that's clearly built to be ridden hard downhill. Race Face AR 30c tubeless-ready wheels come wrapped in a Maxxis Assegai front and Minion DHR II rear, a sensible pairing for a bike that needs to climb on the front tyre's grip and descend confidently on the rear.

Don't confuse this with the Wild LT M20

Orbea also sells a Wild LT M20, and it's a genuinely different bike rather than another version of this one: 170mm of travel front and rear, an Avinox M2S motor instead of Bosch, and a larger fitted 800Wh battery, all aimed at more gravity-focused riding than the Wild TR's climb-and-descend brief. If a listing simply says "Wild M20" without specifying TR or LT, check which suspension and motor system it actually has before comparing prices. You may also see this bike labelled as a 2027 model by a particular retailer; that's a shop's own year convention rather than an official Orbea model-year designation, so it's the specification here, not the label, that tells you what you're actually buying.

Picking your size

Orbea publishes full reach, stack and geometry figures for S, M, L and XL, and reach grows steadily from 440mm at S up to 509mm at XL as the frame gets bigger. Head angle stays a consistent 64.5 degrees and seat angle 78.4 degrees across every size, which means the bike's basic descending stability and climbing position are built into the platform rather than changing size by size. Stem length, handlebar width and dropper-post travel do change with frame size though, scaling up through the range so that a taller rider on an XL gets a longer dropper and a smaller rider on an S gets a shorter cockpit, and the full breakdown is worth checking against the size you're considering. What Orbea doesn't publish on its accessible UK page is any height or inseam guidance, so there's no substitute here for working from the reach and stack figures directly, or trying the actual size if you're between two.

Ownership: warranty, charging and price context

Because the 750Wh battery is built permanently into the frame, day-to-day charging happens with the supplied charger while the pack stays in place, rather than by pulling a removable battery out to charge indoors; if you don't have power near where you store the bike, that's worth thinking through before buying. On warranty, Orbea offers lifetime cover against manufacturing defects on the frame, but as the original owner you need to register the bike within 30 days of purchase to qualify; normal loss of battery capacity over time isn't covered by warranty, which is standard for e-bike batteries generally. On price, £6,159 exists as list-price context for this build, though it isn't confirmed directly on Orbea's current UK page, so treat it as a benchmark for comparing today's offers rather than as a fixed or current figure.

Put together, a genuinely trail-capable carbon chassis, a full-power Bosch motor and a battery you can extend if you need more range mean the rides you plan around this bike don't have to be built around its limits; more often, it's a question of how much trail you want to fit into a day out.
