Sea Otter 2026's e-mountain-bike hall split into two camps - familiar Bosch-powered trail rigs led by Polygon's eye-popping Collosus TE on one side, and a wave of 150Nm DJI Avinox superbikes on the other.
Polygon's Collosus TE: the bike everyone stopped to photograph
BikeRumor opened its Sea Otter 2026 eMTB round-up by noting it had already 'covered the explosion of brands adopting the Avinox motor' - and then spent much of the show looking at everything that wasn't chasing peak watts. The breakout looker was Polygon's Collosus TE, a full-carbon trail/enduro eMTB built around Bosch's Performance Line CX motor and finished in a deep emerald green that pulled crowds at the booth.
It is the more aggressive of Polygon's two e-trail platforms: 160mm of RockShox (or Marzocchi) fork up front, 150mm out back on the brand's compact IFS (Independent Floating Suspension) twin-link, 29in wheels, SRAM Eagle T-Type AXS shifting and four-piston Magura MT7 brakes on 203mm rotors.
“Prices start at $7,500 (~R124 000) and, damn, that color really pops.”

TE vs TLE: two Polygons, two philosophies
Polygon builds the Collosus in two flavours that sum up the whole 2026 eMTB debate. The TE is the full-power bike (Bosch CX, 800Wh, 100Nm). The TLE is the light-and-natural alternative, swapping in Bosch's compact Performance Line SX (60Nm, 400Wh) with a 250Wh PowerMore range extender thrown in as standard, dropping the claimed weight to 22.2kg. The Loam Wolf, which dissected the TLE, reckoned its chassis punched above its travel.
Collosus TE vs Collosus TLE
| Collosus TE | Collosus TLE | |
|---|---|---|
| Motor | Bosch Performance Line CX | Bosch Performance Line SX |
| Peak torque (Nm) | 100 | 60 |
| Battery | 800 Wh | 400 Wh + 250 Wh extender |
| Front / rear travel | 160 / 150 mm | 160 / 140 mm |
| Claimed weight (size M) | 23.8 kg | 22.2 kg |
| US MSRP (from) | $7,499 (~R124 000) (TE 8) | $6,299 (~R104 000) (TLE 8) |
“The geometry and suspension platform combined to encourage an aggressive riding style with impressive support and confidence to ride above the typical 140mm bike class.”
The real story: the Avinox power surge
If the Bosch bikes felt familiar, the other half of the hall did not. DJI's Avinox M2S - 1,500W peak and 150Nm of torque - has become the motor of the moment, turning up on the Commencal Meta Power SX, Ari's sub-$5,000 (~R82 500) builds, the Propain Ekano and more. It is, on paper, the most powerful mainstream eMTB drive unit yet, and it has kicked off a genuine torque arms race that runs from Bosch's measured 60-100Nm right up to the 185Nm Bafang unit in HPC's near-moto Trail Blazer.
The chart below lines up the peak-torque figures the major outlets quoted at and around Sea Otter 2026. More is not automatically better - which is exactly what the reviews started to push back on.

| Peak torque (Nm) | |
|---|---|
| Bosch SX | 60 Nm |
| Bosch CX | 100 Nm |
| Avinox M2 | 110 Nm |

The power question: what the testers actually say
Independent verdicts from across the cycling press — follow each link for the full review.
Awesome, but situational
“You do not need the M2S. But once you have it, it's hard to ignore what it can do.”
Read the full reviewBrilliant hardware, questionable direction
“Both motors deliver their power rapidly, yet never chaotically. They respond instantly to rider input and adapt dynamically to shifting terrain.”
Read the full reviewThe Bosch counterpoint: calm, not crazy
“The Meta Power SX 800 remained notably calm as a result, delivering good traction and seated comfort without feeling overly sluggish.”

Plenty of the show's eMTBs wore badges you already know - but with meaningful firsts. Kona rolled out the Remote 160, its first carbon eMTB, on Bosch's lighter SX motor with a range extender fitted as standard and a claimed weight around 20.8kg. Norco pitched the alloy Sight VLT Bosch A squarely at value at $4,799 (~R79 200)-$6,599 (~R109 000) (US), while Ari showed an Avinox-powered enduro bike aimed at under $5,000 (~R82 500). And after a battery recall, Canyon's Torque ON and Spectral ON are shipping again with revised, aluminium-clad packs.
At the wild end sat HPC's Bafang-powered Trail Blazer, with a 1,050Wh battery and a torque figure that BikeRumor flagged as edging into motorbike territory.
“And it certainly doesn't lack power, perhaps blurring the lines between e-bike and moto, with a Bafang motor delivering 185Nm of torque.”
The case for (and against) a full-power eMTB like the Collosus TE
- 100Nm Bosch CX plus 800Wh means big climbs and all-day range without anxiety
- Full-carbon frame with flagship RockShox, SRAM AXS T-Type and Magura MT7 kit
- 160/150mm travel is genuine enduro-capable terrain coverage
- US pricing from ~$7,499 (~R124 000) undercuts much of the European full-power field
- Optional 250Wh range extender for marathon days
- At ~23.8kg it's a handful to flick on tight trails or lift onto a rack
- Full power is often only fully usable riding solo or on quiet trails (per reviewers)
- Premium money in a crowded, fast-moving segment
- Lighter SX bikes - including Polygon's own TLE - feel more natural for many riders
A genuine full-carbon, full-power do-it-all eMTB at a price that undercuts a lot of the European competition - provided you can live with roughly 24kg of bike.

Buyer questions
How much is the Polygon Collosus TE, and is it sold in South Africa? +
US MSRP runs from $7,499 (~R124 000) (Collosus TE 8 AXS) to $8,999 (~R148 000) (TE 0 AXS). Polygon is sold largely through online retail; South African pricing depends on the importer and includes duty and VAT, so check the live prices above rather than converting the US figure.
What's the difference between Bosch's CX and SX motors? +
The Performance Line CX is the full-power unit - 100Nm and around 750W peak - for big climbs and heavier bikes. The Performance Line SX is lighter (about 2kg) at 60Nm/600W, aimed at lighter, more natural-feeling eMTBs like Polygon's Collosus TLE.
Is the DJI Avinox M2S's 150Nm too much power? +
It's the most powerful mainstream eMTB motor yet at 1,500W peak. Testers love the effortless climbing but note the extra drive is 'only fully usable when you are riding alone, or on quiet trails' (BikeRadar), and several question whether the wattage war is healthy.
How far can the Collosus TE go on one charge? +
Polygon claims up to 190km in Bosch's most efficient ECO+ mode from the 800Wh battery, with an optional 250Wh PowerMore extender. Real-world range on full power and steep terrain will be far lower.
Are these Class 1 / pedal-assist eMTBs? +
Yes - these are pedal-assist trail eMTBs, with assistance typically capped at 20mph (32km/h) in the US/Canada or 25km/h in most other markets. They aren't throttle motorbikes, though high-torque units like the 185Nm Bafang on HPC's Trail Blazer blur that line.

Sea Otter 2026 confirmed the eMTB split-screen: Bosch's refined, well-supported CX/SX platform powering polished do-it-all bikes like Polygon's striking Collosus TE, while DJI's Avinox storms the high-power end with 150Nm. For South African trail riders, the Collosus TE looks like one of the better-value full-carbon, full-power packages on paper - just remember that a ~24kg bike rides (and loads onto the bakkie) very differently to the analogue trail bike it replaces. Watch the live prices above before you convert any US sticker.
