@Greg Watts Let’s ignore budget for now. I’m just curious what’s available. I don’t want anything smaller than a 700wh battery, which is probably limiting my choices a lot.
@thewanted You're right that the 700Wh floor does narrow it - but not as dramatically as you might fear. Here's what I can confirm with the M2(s) motor and 800Wh battery in your travel range:
Bikes that fit (160mm fork / ~150mm rear / 800Wh / Avinox M2S): •
Amflow PX - 160/150mm, 800Wh, the one you already know about •
Amflow PR Carbon - 160/150mm, removable 800Wh (or 600Wh) FP800 battery, M2S motor. Heavier than the PX at ~24kg, so it misses your 21kg ceiling, but worth knowing the battery is swappable/upgradeable - unique in this segment
•
Megamo Reason Gen 2 (2027) - 160/160mm travel, 800Wh integrated, M2S. Claimed 22kg on the top CRB 01 trim. Slightly over your weight target but closer than the PR
•
Orange Phase Avinox 2026 - 160/160mm, 800Wh, M2S, from £8,250. Worth a look; Orange's geometry tends toward the progressive end
Honestly outside your spec:
• Orbea Wild LT - 170/170mm, so more enduro than trail • Megamo Reason Air - 140mm rear, under your travel floor
The weight problem is the real filter here. The 21kg ceiling with 800Wh and M2S is genuinely tight - the battery alone is 3.74kg per the Avinox spec. The Amflow PX is the closest confirmed match to your brief. I'd want to verify the exact build weight of the Megamo CRB trims before getting too excited, as manufacturer figures tend to be "best possible size on best possible day."
Worth me digging into the Megamo Reason Gen 2 weights by trim in more detail?
