Greg's Weekly eMTB Briefing - 15 June 2026A week that's equal parts consumer warning, regulatory musing, and the eternal search for the right cassette. The AmFlow direct-sales situation has kicked off what might be the forum's most useful thread of the year, the Dutch are doing interesting things with bike lane speed limits, and E-Mountainbike Magazine's 2026 group test is out in full — 30 bikes, one winner, and a motor landscape that looks increasingly like a two-horse race. Strap in.
E-Mountainbike's 2026 Group Test Is Out — All 30 Bikes, One Uncomfortable ConclusionE-Mountainbike Magazine has published their headline 2026 eMTB group test, pitting 30 bikes against each other in what is, frankly, the most comprehensive annual benchmark the category has. The headline finding won't shock anyone who's been paying attention: the Avinox M2S — quoting 150Nm and 1500W claimed peak, with independent measurement coming in at approximately 1450W — is setting the performance ceiling, and bikes built around it are dominating the upper tier of the test rankings. The Thömus Lightrider E_MAX and Haibike AllMtn CF 11 TRN/IQ both received individual test coverage as part of the same editorial push, which tells you something about where the editors' attention is landing.
What's worth pausing on is the broader implication. Bosch's Performance Line CX Gen 5 has, via its May 2026 Performance Update 2.0 OTA firmware, finally reached 120Nm — matching where Avinox launched the original M1. Respectable. The problem is Avinox didn't stand still: the M2S is already at 150Nm. Bosch has closed the gap to where the gap used to be, which is not quite the same thing. It's like showing up to a drag race having trained very hard to match last year's record.
The Haibike and Thömus tests are worth reading individually — Haibike in particular represents a serious statement of intent from a brand that's had a complicated few years, and the AllMtn CF 11 specification reflects a clear attempt to compete at the sharp end rather than the safe middle. The full 30-bike comparison is the one to bookmark if you're in any doubt about which motor platform you want under you in 2026.

Thömus Lightrider E_MAX: The Swiss Entry in the Motor WarsE-Mountainbike have also published a standalone test of the Thömus Lightrider E_MAX, which is notable primarily because Thömus is one of those brands that tends to get overlooked outside central Europe, despite consistently building bikes that testers find extremely difficult to fault. The fact it's in the running for best eMTB of 2026 alongside considerably larger-budget competitors is, to put it diplomatically, an editorial statement. Swiss build quality doing Swiss things, quietly and without a great deal of fuss — which, given the noise levels from some other corners of the market, is almost a political act.

Haibike AllMtn CF 11 TRN/IQ: A Proper Return to FormThe Haibike AllMtn CF 11 TRN/IQ lands as the brand's most credible high-end eMTB push in some time, and E-Mountainbike's test reflects that. The carbon frame and top-tier spec sheet suggest Haibike have looked at where the category is heading and decided to stop hedging. Whether they've fully nailed it or merely got very close is what the full test unpacks — either way, it's in the group test conversation, and that alone is progress.

TQ's Toni Rossberger Profile: On Building Things Because You Want ToE-Mountainbike have run a thoughtful long-form piece on Toni Rossberger and TQ Systems — the engineering philosophy behind the HPR60 and its predecessor the HPR50. The framing is essentially: what happens when an engineer-led company decides to build a motor that satisfies their own standards rather than chasing headline torque figures? The answer, in TQ's case, is a 60Nm, 1.924kg unit that measures ~350W claimed peak — numbers that look modest next to the Avinox M2S's 150Nm until you're actually aboard something TQ-powered and wondering why it feels so composed. Not everything worth riding shows well on a spec sheet. This piece is worth your time if you care about the 'why' behind the hardware, not just the 'what'.

The Dutch Are Trialling 12mph Bike Lanes — And Nobody Is Entirely Happy About ItA piece in The Guardian this week covered a Dutch trial of designated 12mph (approximately 20km/h) bike lane speed limits — and, predictably, everyone involved is mildly annoyed for slightly different reasons. For eMTB riders the direct relevance is limited, given most of us are transporting the bike to a trailhead rather than commuting on it at regulated speeds. But the broader conversation around speed and power limits is one that tends to drift in the direction of 'and therefore all electric bikes should be restricted', which makes it worth watching. Speed pedelecs already exist as a legal category — registered, insured, MoT'd — but they exist in a regulatory uncanny valley that makes them impractical for most riders. As @Fangs2k noted in the forum thread, the solution technically exists — it's just been designed to be inconvenient. Classic regulatory approach.

FROM YOUR FORUM THIS WEEK
WARNING: Do Not Buy an AmFlow From the AmFlow WebsiteThe week's most practically useful thread, and the one you should send to anyone who's currently got an AmFlow tab open. With 73 replies already, the thread has accumulated enough consumer experience to constitute a genuine buyer's resource — and the headline is not ambiguous. The AmFlow PL Carbon is built around the Avinox M1 (120Nm, 1000W claimed peak) and has attracted serious interest as a high-value performance option, but the direct-purchase experience via the official website is, apparently, a different proposition entirely. The community's collective intelligence is doing the work here that brand PR isn't. If you're considering an AmFlow, read this before you do anything else.
Join the discussion Chainring Guards for the AmFlow PX: A Community Engineering ProblemRelatedly, @Big Ted has been working through a DIY bash plate solution in aluminium — 2mm stock, spaced off the motor cover rather than bolted through the M4 mounts — and is now wondering whether a PL spider swap would open up the world of 104 BCD chainring guards. It's the kind of thread that starts as a practical question and becomes a minor engineering seminar. @Kr1s suggested frame film as the priority, which @Paulquattro received with appropriate scepticism — if you're worried enough about chainring impacts to fabricate aluminium bash plates, PPF is not quite the solution you had in mind. Good thread, useful for anyone running an AmFlow on anything rocky.
Join the discussion SRAM Wireless on a Shimano Cassette? Danny's Got Questions@Danny521 dropped a drivetrain compatibility question that is, by his own admission, possibly dumb — could a SRAM wireless shifter run a Shimano 12-speed cassette, or vice versa? The answer, delivered calmly and without condescension by @nickf in what is genuinely one of the clearer explanations of drivetrain indexing you'll find, is: no, and here's exactly why the cable pull ratios and derailleur leverage geometry don't agree. Not a dumb question at all, actually — it's the kind of thing that isn't obvious until someone explains it properly. Worth a read if you've ever wondered the same thing and not asked.
Join the discussion Dutch Speed Limits Hit the Forum@Roughshod flagged the Guardian's Dutch 12mph bike lane trial and opened up the speed/power limit debate, noting he commutes on a Fazua-powered electric gravel bike and would feel the pinch. A compact but worthwhile discussion for anyone who thinks regulatory creep only happens to other people.
Join the discussion Crashes — The Thread Nobody Wants to Need@Just gan opened a sobering thread referencing a serious local accident, and @RustyMTB[/URL] [URL='https://www.emtbforums.com/posts/698705/']added news of a 26-year-old from Worthing left paralysed following an accident in Tasmania[/URL]. [USER=45651]@Pizzman[/URL] [URL='https://www.emtbforums.com/posts/698687/']put it plainly[/URL]: his riding buddy broke his chest plate and three ribs sliding out on a green warmup berm — not a black diamond, not a jump, a warmup lap. "It's a dangerous hobby to be sure." Worth reading, if only as a reminder that armour isn't just for the nervous.

[B]🆕 Mystery Cassette Identified[/B]
[USER=15309]@_Jason_South_Wales_ couldn't identify the cassette on his 2022 Cube Reaction Hybrid SLT 750 — @dreys identified it as low-end Shimano 12-speed Deore and confirmed the upgrade path (Deore → SLX → XT → XTR, all compatible). @Pyr0[/URL] [URL='https://www.emtbforums.com/posts/697018/']confirmed via spec sheet it's the CS-M6100 10-51T[/URL]. Thread closed in under an hour, community does its thing. Nothing flashy, just useful.

[B]🔥 ONGOING DEBATES[/B]
[B]Avinox M2S Rattle — 304 Replies and Still Going[/B]
The M2S rattle megathread continues to accumulate posts at a rate that suggests this is not a problem that has quietly been fixed in production. If you're hearing something from your bottom bracket area on an M2S-equipped bike and hoping it's nothing, the forum's collective troubleshooting experience suggests it is, in fact, probably something. The thread is a genuinely useful diagnostic resource at this point.

[B]Avinox M2S Launch Thread — 522 Replies[/B]
Still the forum's busiest ongoing motor conversation. The M2 and M2S announcement thread has long since evolved from hype to detailed real-world ownership discussion, and at this volume it's functioning more as a living FAQ than a news thread.

[B]Trek Slash+ eMTB — 311 Replies[/B]
Still generating discussion. The Slash+ remains one of the more talked-about recent launches, and the thread hasn't reached the "is anyone still posting here?" phase yet.

[B]Bosch + Garmin Integration Project — 333 Replies[/B]
Community-built Bosch/Garmin integration project, still active. One of those threads that exists entirely because the manufacturers won't do it themselves. Nothing says 'market opportunity' like a 333-reply workaround thread.

[B]📚 BIG THREAD UPDATES[/B]
The SZZS CEF50 main thread remains the forum's single most information-dense resource, with over 5,000 posts logged since the last summary update and 1,673 community facts accumulated. If you're doing anything unusual with a Specialized motor system or need a tuning reference point, it's the first place to look. At this rate it'll need its own search engine.
[URL='https://www.emtbforums.com/threads/32042/']📎 Thread[/URL]
The Levo Gen 4 rumours thread has over 3,500 posts since last summary and over 1,000 community facts — still the forum's best barometer for where Specialized's next generation is heading, and still definitively in the "rumours and some facts" phase.
[URL='https://www.emtbforums.com/threads/35957/']📎 Thread[/URL]
The BLEvo thread, Trek Fuel EXe Megathread, and Official Levo SL Thread are all ticking over with steady activity — between them they represent the forum's institutional memory for three of the most popular light-eMTB platforms. Worth knowing they exist when the diagnostic questions come up, because they will.
