This new Avinox motor is crazy.

Product Reviewed

Avinox MS2 e-bike motor (used in the T-Wing Flux long-travel carbon e-bike).

Key Features Mentioned

Motor: New Avinox MS2

• Up to 1,500W peak power (with the higher-end build kit)
• 150 Nm torque
  • ~25% more torque than the prior MS1 (described as changing the game)

Efficiency / Noise Improvements (Claims)

• Less resistance than MS1 → expected more efficient battery use
• Reduced clutch noise/rattling

Bike Platform Tested: T-Wing Flux

• High-pivot long-travel design
  • Different from the previously released T-Wing Turbo Forest Pro
• Suspension:
  • 180 mm fork
  • 178 mm rear travel
• Mixed-wheel capability
  • Can run 29er or mixed setups
  • Switching to a 29er reduces travel to 170 mm
• High-low flip chip
  • Adjusts for wheel size / ride characteristics
  • The lower mixed-wheel position is described as slacker
• Short chainstay
  • Helps with maneuverability

Pros (What Stood Out)

• Extremely strong climbing performance
  • Rider describes it as “very very torquey” and “a weapon”
  • On climbs, it holds speed easier and keeps higher RPMs longer
• Clear advantage vs MS1 and competitors (positioning)
  • MS2 is another step above MS1 in power/torque
  • Claim: MS1 already outperforms top-end Bosch / Shimano / SRAM in torque/power
• Trail ride feel / performance
  • Traction praised on the first ride
  • Playful and maneuverable, aided by the short chainstay
  • Quietness improvement:
    • XT Di2 derailleur quieter than before
    • Motor/drive noise expected to benefit from reduced clutch noise
• Downhill control comfort
  • Described as comfortable with strong control
  • Still manageable even though geometry leans toward steep terrain

Cons / Concerns (or Tradeoffs)

• Wheel-size tradeoff
  • Running a 29er reduces travel to 170 mm
• Cornering feedback from first-ride notes
  • Some rear wheel skating on flatter/drier corners (expected with smaller/mixed traction)
  • Some front-end pushing / understeer
  • Requires staying “on it” through corners
• Potential durability concern
  • Main worry: durability of the “little idler wheel”
  • Rider observed it already being noisy, raising concern about wear under high torque

Comparisons Made

MS2 vs MS1 (Previous Avenox Motor)

• Higher peak power: up to 1500W
• Higher torque: 150 Nm (+25%)
• Claims:
  • Less resistance
  • Less clutch noise
• Noted performance difference:
  • Better speed holding and sustained RPMs on climbs

T-Wing Flux vs Other T-Wing Model (Turbo Forest Pro)

• Flux uses a different high-pivot configuration
• Flux also offers more travel

MS1 vs Other Major Motor Brands

• Claim: MS1 is already more powerful/torquey than top-end Bosch / Shimano / SRAM

User Experience / First-Ride Impressions (Narrated)

• Climbing
  • Required careful assist-mode selection (auto vs turbo) due to strong torque
  • Rider joked about getting “spat on your ass” if not careful
• Trail behavior
  • Strong traction and comfort
  • Geometry favors steeper / rowdier tracks
• Jumps / rollers
  • Suggested it may feel slightly heavier or more lethargic than shorter-travel or lighter setups
  • Still described as rideable and maneuverable
• Noise test mentioned
  • Rider describes performing a noise test on a rocky trail, implying attention to drive noise under load

Unique Points List (Distinct Product-Related Claims)

1. Avinox MS2 motor introduced; mentioned as part of International Avinox Day coverage.
2. MS2 delivers up to 1,500W peak and 150 Nm torque.
3. 150 Nm is +25% torque vs MS1.
4. Expectations of new battery/drive behavior (noted as drawing more amps); battery usage vs MS1 to be tested.
5. MS2 paired with the T-Wing Flux: 180 mm / 178 mm high-pivot carbon e-bike.
6. Flux described as a monster truck, aimed at aggressive trails.
7. High-pivot design highlighted as different from earlier T-Wing models.
8. Mixed wheels supported; 29er possible but reduces travel to 170 mm.
9. High-low flip chip adjustability; low mixed position felt slacker.
10. Short chainstay improves maneuverability.
11. MS2 torque may reach the rider’s personal comfort limit; careful mode selection needed.
12. Two build kits: - Both: carbon frame, MS2, and an older internal 800 Wh battery - Higher-end kit: 1500W peak - Lower-end kit: 1300W peak (still up to full 150 Nm torque)
13. MS2 vs MS1: better speed holding and higher RPMs for longer on roads/climbs.
14. Claim: less resistance → improved efficiency (battery expected to last longer than MS1).
15. Claim: reduces clutch noise/rattling (less noise than MS1).
16. Stock weight noted: ~48 lbs (22 kg).
17. Cornering behavior depends on setup/terrain: rear can skate; front can push.
18. Rider worries about idler wheel durability; already noisy.
19. Rider ends excited and expects tuning/setup improvements.

Speaker Views (Separate Contributors)

• Primary rider/reviewer (main narrator):
  • First-ride impressions on climbing, traction, handling, noise/comfort, and the idler durability concern.
• Show host / Pinkbike intro voice:
  • Launch context and spec/marketing framing (MS2 torque/power + bike links).

Overall Verdict / Recommendation

Strong recommendation for riders prioritizing climbing punch and aggressive long-travel handling. The Avinox MS2 is presented as a clear step up over MS1, with major torque and speed-holding gains and expected improvements in efficiency and noise.

Main potential downside: unknown long-term durability of the idler wheel, which the reviewer is specifically watching for during future testing.
