Honda stopped teasing today. At EICMA in Milan, Honda gave the RN0 its official world premiere — Honda’s first high-end e-MTB, and the first mountain bike to wear the wing badge in roughly two decades. We’ve been tracking this bike since a prototype surfaced at Sea Otter Europe in September, and the headline back then was that Honda had skipped the horsepower war and picked Shimano’s existing EP8 motor. That headline just changed. The production bike doesn’t run EP8. It runs something that doesn’t even have a public product page yet.

Here’s the short version: carbon monocoque frame, a “Gullarm” single-pivot rear end braced by three linkages, and an all-new Shimano drive unit — the EP810 — putting out 100Nm and 750W from a 720Wh battery. One build. Three sizes. No price. No region. No ship date beyond “2027.”

This Isn’t the Bike We Saw in September

Honda and the real surprise here isn’t that the RN0 showed up — we already knew it was coming. It’s what changed between the Sea Otter Europe prototype and this EICMA production reveal. Back in September, the prototype ran Shimano’s EP8, an 85Nm motor that’s been shipping on bikes like Kona’s Remote line for a couple of years now. We called that choice deliberate — Honda picking the known, trail-smooth option over DJI’s or Bafang’s bigger numbers.

Turns out it wasn’t the final choice at all. It was a placeholder. The RN0 that premiered today runs the EP810, a drive unit Shimano hasn’t released to any other bike brand, with more torque (100Nm vs. 85Nm) and more peak power (750W vs. EP8’s figures) than the motor Honda showed five months ago. That’s a meaningful swap this late in a development cycle, and it tells you Honda wasn’t just waiting on Shimano to finish a paint job — it was waiting on an actual new motor generation.

What Is the Honda RN0?

The Honda RN0 is a carbon-frame, full-power e-MTB co-developed by Honda and German e-MTB builder ROTWILD, running a new Shimano EP810 motor (100Nm/750W) and a 720Wh battery. It premiered at EICMA 2026 in a single build spec — Fox Factory suspension, Shimano XT brakes and Di2 drivetrain, DT Swiss wheels, Schwalbe radial tires — with a claimed weight near 24kg and a targeted 2027 launch.

That ROTWILD partnership is the same arrangement we flagged in September, just described more directly now. Honda’s earlier materials routed the relationship through ADP Engineering, ROTWILD’s parent company. EICMA’s messaging drops the middleman language and just says ROTWILD. Same company, same expertise, clearer billing.

How Does the Shimano EP810 Compare to Other eMTB Motors?

1. Vs. Shimano EP8 (the prototype’s motor): EP810 adds roughly 15Nm of torque and more peak output, and at 2.3kg it’s a genuinely light package for the numbers it’s claiming — not a bigger, heavier unit bolted on for bragging rights.
2. Vs. DJI’s Avinox platform: Still well short of DJI’s triple-digit-torque, attention-grabbing output. Honda and Shimano are chasing smoothness, not the top of the spec sheet.
3. Vs. Bosch’s latest Performance Line CX: Reviewers who’ve actually ridden the RN0 aren’t convinced EP810 wins this fight yet — more on that below.
4. Vs. Trek’s Rail+ (120Nm) or Specialized’s Turbo Levo 4: EP810’s 100Nm sits below both of the full-power eMTBs Honda is actually cross-shopped against. On paper, Honda showed up to a horsepower fight without the biggest horsepower.

The Build: One Spec, No Options

Honda isn’t giving buyers a choice here, and the spec it picked leans hard into “known-good” rather than flashy. Fox 36 Factory up front at 160mm, a Fox Float X Factory shock controlling 145mm out back, Shimano XT four-piston brakes, and an XT Di2 12-speed drivetrain with auto-shift. DT Swiss M1900 wheels run a mullet setup — 29-inch front, 27.5-inch rear — wrapped in Schwalbe Albert tires built on Schwalbe’s radial casing, the same perpendicular-thread construction we found delivers real grip gains at a real cost in sidewall durability during our own testing.

That radial spec is worth sitting with for a second. Every radial tire we’ve tested so far has been an aftermarket swap — riders and reviewers bolting Alberts or Magic Marys onto bikes that shipped with something else. The RN0 is the first bike we’ve seen spec radial tires straight from the factory, on the only build it offers. If Honda and ROTWILD trust radial casings enough to make them the only tire option on a bike with no price and no market yet, that’s a vote of confidence from people who had every reason to pick the safer, more durable bias-ply default instead.

A 2.2-inch color display sits in the top tube, charges over USB-C, and ties into a Shimano app for ride customization — standard-issue stuff for a 2026/2027 premium eMTB, not a differentiator.

Does It Actually Ride Well?

Here’s where the skepticism has to kick in, because the people with actual seat time on the RN0 aren’t uniformly impressed. BikeRadar’s first-ride review calls the bike “merely okay rather than exceptional” — praising “playful handling” and “surprisingly composed suspension” while flagging two real problems: a hollow carbon frame that’s noticeably noisy on rough ground, and a motor that “feels inferior to the latest competition,” specifically naming DJI’s Avinox M2S and Bosch’s latest Performance Line CX as the motors EP810 is losing to on feel.

That’s a blunt verdict for a motor Shimano hasn’t even released publicly yet, and it’s worth taking seriously precisely because it’s not a hit piece — the same review likes how the bike handles. A new motor and a first-generation frame getting mixed marks on a first ride isn’t unusual. It’s also not nothing. Honda built its whole re-entry pitch on “Man Maximum, Machine Minimum” — minimizing mechanical intrusion so the rider feels like the star. A motor that reviewers can feel underperforming, on a frame loud enough to notice, cuts against that pitch before a single unit has shipped.

Where the RN0 Actually Has to Compete

Honda isn’t launching into a vacuum. A ~24kg, 160/145mm-travel, 720Wh full-power e-MTB with no confirmed price lands in the same conversation as Specialized’s Turbo Levo 4 — which we measured at 52lb (about 23.6kg) for the S-Works build, running at $8,999-$13,499 — and Trek’s Rail+, which ships today with 120Nm and an 800Wh battery for 160mm front and rear travel. Both of those bikes have years of real-world mileage, established dealer networks, and motors riders already trust. The RN0 has a motorcycle brand’s name, a boutique German frame partner, and a motor nobody outside Honda’s test program has logged real hours on.

That’s not a knock specific to Honda — it’s the position every first-year eMTB from a new-to-category brand starts in, the same spot Ducati occupied when it brought motorcycle styling and performance targets to bicycles through a manufacturing partner rather than building the expertise from scratch. Brand weight gets you noticed at EICMA. It doesn’t get you a service network, and it doesn’t make a loud frame quiet.

What We Still Don’t Know

The list of blanks is longer than the list Honda actually filled in:

• Price. Nothing. Not a range, not a market position relative to Levo or Rail+.
• Region and availability. Honda hasn’t said where the RN0 sells first, or whether “2027” means early or late in the year.
• Long-term EP810 reliability. It’s a brand-new motor. Nobody has logged a season on one.
• Whether the noise and motor-feel complaints get addressed before production. EICMA bikes can still change between now and a real production run.

Who Should Actually Care About This

Anyone tracking the eMTB motor fight. EP810 landing first on a Honda, ahead of any other brand, is a real data point — Shimano handed its newest motor to a company with zero eMTB track record before giving it to anyone with an existing dealer base.

Riders curious about motorcycle brands crossing into MTB. Honda joins Ducati as a second major motorcycle manufacturer building a real eMTB program instead of a badge-engineering exercise, and the RN0’s early reviews suggest that transition is still rough around the edges.

Shoppers who want to see how this shakes out before buying. If you’re choosing between a Levo 4 and a Rail+ right now, nothing here changes that decision today.

Who Should Skip This

Anyone shopping for an eMTB this winter. No price, no region, no ship date beyond a calendar year. Treat 2027 as a floor.

Riders who need a quiet frame. BikeRadar’s complaint about the hollow carbon construction being noisy on rough terrain isn’t a small thing if trail noise bothers you — and there’s no fix confirmed yet.

Anyone assuming EP810 beats Bosch or DJI on feel. The one outlet with actual trail time says the opposite, for now.

The Bottom Line

Honda’s first mountain bike in nearly twenty years premiered today with a motor nobody outside Shimano’s own test fleet has ridden before this week, a single build spec that leans on proven Fox and Shimano parts to de-risk everything around that new motor, and the first factory-spec radial tires we’ve seen on any production eMTB. That’s a genuinely interesting bike on paper. The first people to actually ride it aren’t fully sold — the frame’s loud, and the headline new motor isn’t winning on feel against Bosch or DJI yet. Worth watching through 2027, not worth cross-shopping against a Levo 4 or Rail+ until Honda names a price.
