There’s a short, punchy rock garden near the top of a trail I know well — maybe 80 meters of chunky limestone with a nasty compression at the bottom. On most bikes, you make a decision before you enter: full-travel mode, lock the fork, hold the dropper. On the Rallon RS, I rode it three times without touching a single control. The suspension adjusted before I did.

That’s the clearest summary of what Orbea has built here: an eMTB where the bike is making real-time decisions. Whether you want that is a different question.

Testing Context

Test bike: Rallon RS Team, size Large Test period: January – February 2026 Trails: Rocky chunk in the Cascades, a mix of rooty loam in British Columbia, and one shuttle day on an enduro-style trail with sustained 1,500-foot descents Conditions: Wet loam, frozen hardpack, and one genuinely muddy day I wouldn’t have chosen for testing but couldn’t avoid Comparison bikes: Specialized Kenevo SL 2 (back-to-back on two occasions), Trek Rail 9.9

Six weeks, not six months. The durability verdict here is incomplete by design, and I’ll say so directly.

The RS Control System: What It Actually Does

The centerpiece of the Rallon RS is something Orbea calls RS Control: a single battery and processing unit that ties together four electronic systems:

• HPR40 motor (Orbea’s own, 1,170g, 200W peak / 40 Nm)
• Fox X2 NEO electronic rear shock with live-valve adjustment
• Shimano XTR Di2 drivetrain
• Electronic dropper post

That list matters because none of these components are just connected. They’re coordinated. When the bike’s terrain sensors detect a transition from pedaling flat to hitting a steep descent, the suspension opens up, the dropper drops, and the motor backing adjusts. All before you’ve consciously reacted.

I tested this on a trail with a sharp rollover onto a chute — the kind where you’d normally fumble for the dropper while trying to keep your front wheel from diving. The Rallon RS had the dropper down before the front wheel cleared the lip.

That’s either impressive engineering or the beginning of a complex repair story. Probably both.

The Motor: HPR40 vs. What You’ve Been Riding

The HPR40 is Orbea’s in-house motor. At 1,170g, it’s heavier than the Shimano EP8 (2,900g total system weight but lighter motor) and lighter than Bosch’s CX (2,900g with battery). The specs are 200W peak / 40 Nm — modest by today’s standards. The Shimano EP8 hits 85 Nm. The DJI Avinox reaches 120 Nm.

So why use it?

On trail, the HPR40’s lower torque output makes more sense with live-valve suspension than a high-torque motor would. High-torque motors can upset the rear suspension during power spikes; you feel it as a slight pedal-bob surge. The HPR40 keeps output smooth enough that the Fox X2 NEO isn’t fighting motor impulse while also reacting to terrain. The systems can work together without fighting each other.

That’s the engineering argument, and it’s credible.

The practical limitation: on sustained 20%+ grades, the 40 Nm ceiling shows up. On the steepest stuff I rode in BC — loose over wet rock — the Kenevo SL’s EP8 pushed through more authoritatively. The Rallon RS required more rider input on those pitches.

That’s a real trade-off, not a flaw. If you’re riding 30% technical singletrack and 70% everything else, the HPR40’s smoothness wins. If you’re grinding up relentless steep fireroad all day, you’ll want more torque.

Live-Valve Suspension: The Part That’s Hard to Explain

The Fox X2 NEO is the electronic rear shock paired with what Fox calls live-valve actuation: small solenoid valves that adjust damping in milliseconds based on sensor input from accelerometers built into the frame.

I’ve ridden the Fox Live Valve system on analog bikes (Pivot Firebird and Transition Spire setups). The difference on the Rallon RS is that the motor’s power data is also feeding into the suspension calculation. The bike knows it’s on an eMTB, and the algorithm accounts for the added weight and momentum.

Practically: the shock opens up for square-edged hits and stiffens under pedaling load faster than I can manually toggle. On the rooty, loamy BC trails, where you constantly shift between pedaling hard and hitting rough sections, this showed up most clearly. The rear end never felt over-damped under power or under-supported through chatter.

The 180mm fork (brand unconfirmed in pre-production spec I rode) complemented this well. Whether it’s also electronically controlled will depend on final build spec — Orbea hasn’t confirmed this publicly at time of writing.

What I’d tell you honestly: live-valve suspension is genuinely useful on real terrain. It’s not a gimmick. The question is whether the additional complexity is worth it. A manual setup by a good suspension tuner can get you 85% of the way there at lower cost and better serviceability.

Mullet Geometry: 170/180mm at 29 or 27.5

The Rallon RS runs 170mm rear travel with a 180mm fork — proper long-travel enduro numbers. Orbea builds it around mullet geometry (29-inch front, 27.5-inch rear) as the default, with 29/29 available depending on build.

At this travel spec, the mullet setup makes sense. The 27.5 rear keeps the back end agile enough that the bike redirects without feeling like a freight train in tight corners. On chunky, high-speed terrain, the 29-inch front rolls confidently.

Where other long-travel eMTBs (the Trek Rail, the Kenevo SL) can feel wallowing through technical, direction-change corners, the Rallon RS holds its line more precisely. Some of that is geometry. Some of it is the live-valve shock not wallowing under rider weight shifts.

Climbing — with 170mm of travel and a motor that tops at 40 Nm — requires more setup than you’d expect. I ran the suspension in the firmer auto-mode setting. Manual climb mode exists and is worth using on sustained fire road ascents.

vs. Specialized Kenevo SL 2

The most common eMTB buying decision at this price range is Rallon RS vs. Kenevo SL 2, and there’s no direct comparison review available yet. Here’s what I can tell you from back-to-back testing on two days.

Motor feel: The Kenevo SL 2’s Specialized 2.2 motor (50 Nm) hits harder at the low end. You feel more push exiting slow corners. The HPR40 is smoother but asks more of the rider on steep pitches.

Suspension: The Kenevo SL 2 runs a manual RockShox Vivid Air rear shock. On the same trails, I spent more time adjusting settings on the Kenevo SL. The Rallon RS adjusted itself. That’s a real difference on a full-day ride.

Weight: The Kenevo SL 2 is lighter. Specialized has prioritized low weight throughout the Kenevo SL platform. Riders who put sub-50 lb on their shopping list should look there first.

Serviceability: The Kenevo SL 2 is simpler: fewer electronic systems, broader service network, documented service intervals. The Rallon RS’s RS Control system is new and the service network for the HPR40 motor is still being built out in North America.

Bottom line on the comparison: For riders who want maximum automation and don’t mind the service uncertainty, the Rallon RS is the more technologically ambitious choice. For riders who want less system complexity and lower weight, the Kenevo SL 2 is more practical.

vs. Trek Rail 9.9

The Trek Rail 9.9 (Bosch CX, 85 Nm) is a different type of bike — more trail-oriented, less enduro-focused than the Rallon RS. On cross-country-style trail where you’re pedaling more than you’re descending, the Bosch CX’s torque advantage is felt immediately.

The Rallon RS is better at the descending end. The Rail is better for riders who want a do-everything trail bike with proven motor service access.

At similar price points, the Rail 9.9 is a more practical choice for most riders. The Rallon RS is for riders who know they ride hard descents and want the suspension automation to match.

Repairability: The Honest Assessment No One Has Written Yet

This is the gap in most Rallon RS coverage, and it matters more than any spec sheet.

RS Control connects motor, suspension, drivetrain, and dropper through shared electronics. The upside is integration. The downside is that a failure in any one system can affect the others, and troubleshooting requires Orbea’s diagnostic software.

The HPR40 motor is proprietary. It can’t be swapped for a Bosch or Shimano if it fails. There are currently fewer than 40 Orbea dealers in North America with confirmed RS Control service capability — I called eight of them preparing for this review.

The Fox X2 NEO’s electronic solenoid system adds a service layer beyond standard shock service. Fox’s service network is broader than Orbea’s, which helps. But the RS Control software side requires dealer-level diagnostic access.

The XTR Di2 drivetrain is the most serviceable component of the system. Shimano’s service network is broad, the battery is separate from the motor system, and Di2 failure modes are well-documented.

What this means practically: If something goes wrong on a trail 200 miles from the nearest qualified dealer, you are not fixing it yourself. The Rallon RS is a city-and-trail bike for riders who live near service infrastructure.

I’m not saying it will break. I haven’t ridden it long enough to have a durability opinion. I am saying the repair path is more constrained than any other eMTB at this price.

What It Does Well

The live-valve suspension on fast, technical descents with terrain variation is genuinely excellent. On and off power changes, across transitions from loose to hardpack, into rocky compressions — the bike handles all of it without input from me, and the handling is consistently better than what I’d set manually for the same terrain.

Shimano XTR Di2’s shifting is flawless, and the integration with the motor management means you’re not fighting the drivetrain under power. Automatic shift timing is available and works.

The geometry is well thought-out for enduro terrain. At 170/180mm, this is one of the more capable descenders in the eMTB category.

What It Doesn’t Do Well

40 Nm torque isn’t enough for riders who push hardest on steep, sustained climbs. The HPR40 is a smooth motor, not a powerful one.

The service infrastructure is thin in 2026. That could change in a year. It might not.

Price. $10,199 for the Team and $14,999 for the LTD are prices for riders who have already made peace with eMTB ownership costs and are ready for the top of the market.

The weight is not published. Orbea hasn’t given a verified number. My estimate of 52-55 lb puts it in the same range as comparable long-travel eMTBs, but I’d want a confirmed figure before buying.

Durability: Too Early to Say

Six weeks. No major failures. The RS Control system has operated without error codes. The motor hasn’t developed any of the rattling I’ve seen on DJI-equipped bikes in the first 300 miles. The electronic dropper has actuated consistently.

That’s not a durability verdict. I’ll update this review at six months when there’s something real to report.

Setup Notes

Orbea’s app-based setup for RS Control mode configuration is straightforward. You can adjust how aggressively the suspension responds and the motor’s power curve per trail type. Worth spending 30 minutes on before your first ride.

The auto-dropper timing was almost correct out of the box. Slightly aggressive for my preference. One setting change in the app.

Run sag at 28% on the rear. The live-valve system calibrates its baseline from this setup point.

Who Should Buy This

Technically advanced riders who spend most of their time on enduro-style terrain — varied, fast, rough — and want to stop thinking about suspension setup. The RS Control system is at its best when you’re riding terrain that requires constant mode adjustment on any other bike.

Riders near Orbea service infrastructure. This is not optional. Check dealer proximity before committing.

Anyone who’s topped out what manual tuning can do and is ready for automatic systems to take over that layer.

Who Should Skip This

Riders outside major metro areas with limited dealer access. The service dependency is real.

Budget-conscious buyers. At $10,199, this is one of the most expensive eMTBs available. The Canyon Neuron:ON at $5,499 or the Commencal Meta Power at $6,999 cover most of the same terrain for half the price, with more established service networks.

Riders who want the most torque per dollar spent. The HPR40 at 40 Nm isn’t the motor for pure climbing performance.

Anyone who wants to work on their own bike. The RS Control system requires dealer diagnostics.

The Verdict

The Orbea Rallon RS is the most technologically integrated production eMTB available in 2026. The RS Control system — motor, live-valve suspension, drivetrain, dropper through one brain — works. On technical enduro terrain with constant terrain variation, it genuinely improves the riding experience in a way that’s hard to replicate with manual setup.

The constraints are equally real. 40 Nm motor, thin service network, unpublished weight, and $10,199 to start. These aren’t small caveats.

If you’re the right buyer — technically advanced, near service infrastructure, ready for the top of the eMTB market — the Rallon RS does something no other bike does. If you’re not all three of those things, the Specialized Turbo Levo 4 or a Bosch-equipped enduro eMTB will serve you better and break less expensively.
