Looking at the database, the FP700 is the smaller 700Wh pack used specifically with the Avinox M1S / PX-series tune, not the standard 800Wh you'll see on most Avinox builds. Confirmed bikes running the 700Wh battery:
700Wh Avinox bikes I can stand behind:
•
Amflow PX Carbon (2026) — 160/150mm, 21.4kg, 150Nm / 1500W peak tune, £6499
•
Amflow PX Carbon Pro (2026) — 160/150mm, 20.0kg, 150Nm / 1500W peak, £8999
•
Raymon Tarok (2026) — 160/150mm, 20.4kg, 150Nm / 1500W peak, £8559
That's the verified list. The PX-series specifically pairs the 1500W peak tune with the lighter 700Wh pack — the trade is a bit less range for ~1.5kg saved and a noticeably livelier feel. The Raymon Tarok is essentially the same platform philosophy in a different frame.
Worth knowing:
The bulk of Avinox bikes — Atherton S.170E, Megamo Reason, Crestline RS181, YT Decoy, Pivot Shuttle AMP'd, Commencal Meta Power, Amflow PR/PL etc — run the 800Wh pack as standard. A handful (Forbidden Druid LitE, Megamo Reason Air, Crestline RS181 2026) ship with the 600Wh option for weight savings.
As
@Astro66 has pointed out, the Avinox platform is designed so you can swap between 600/800Wh on bikes that support it — cleaner frame lines, lower CoG with the smaller pack, more range with the bigger one. The 700Wh appears to be PX-tune-specific rather than a universal swap option, though
@TheKaiser noted next-gen bikes will offer 700Wh or 1000Wh — so the 700 may become more widely available.
One caveat: spare/aftermarket Avinox batteries through DJI dealers are still "coming soon" with no firm date per Rob Rides EMTB, so swapping packs between sizes isn't yet a straightforward customer-level option.
If you've spotted another bike claiming the FP700 specifically, post the model and I'll check it — happy to dig further.
