Forbidden Druid e — how do you remove the battery?
- Thread starter Chopchop

Right, here's the honest answer on the Druid E: that 800Wh Avinox battery is not a quick-swap job. It lives in the downtube and the consensus on here is that you need to drop the motor to get it out — it's not a trailside fumble-it-out-the-bottom affair.
The reality of the Avinox setup:
@Rob Rides EMTB found the DJI Avinox battery swap requires motor removal, which makes it distinctly not user-friendly compared to, say, a Bosch PowerTube or the Levo Gen 4 (which Polar reckons comes out in under 10 seconds). So if you were hoping to carry a spare for back-to-back bike park laps, the Druid E isn't built around that idea.
How it's done:
• It's a workshop-style job, not a roadside one. You'll be removing the motor (and display/cabling as needed) to access the pack — Astro66 noted exactly this pattern for accessing the battery on these systems.
• That means motor mounting bolts, idler/guard clearance, and unplugging the battery connector — all of which want doing carefully and torqued back correctly.
• Realistically, unless you're confident with the motor mount and have the right tools, this is one for your dealer or a decent workshop. Getting the torque wrong on motor bolts or pinching a cable is a far more expensive mistake than the inconvenience.
One genuinely useful Avinox quirk:
@jcmonty found the eDruid still gives motor support and AXS shifting at a displayed 0% — so "empty" isn't actually flat. Handy to know if you're nursing it home rather than wrestling the pack out mid-ride.
Why are you taking it out? That changes my advice:
• Air travel — worth a proper plan. Kitnz has shipped a Forbidden battery separately in a plastic plan-carrier tube with foam padding, so there are sensible workarounds.
• Storage / fault / replacement — book it in, frankly. Not worth the risk for a one-off.
• Range — the 800Wh pack genuinely goes a long way; reviewers got 3,800ft of climbing with 25–30% still showing.
If you want, the owners' thread is full of people who've actually had theirs apart:
Tell me what you're trying to do — travel, fault, or just storage — and I'll point you at the exact steps.

Looks like Forbidden is dropping some eBikes in 2025 and have been testing the DJI motor. Thought that's pretty exciting as its a local brand for me and we sell them at the shop I work at. A little disappointed to read they might only have a 600wh battery but I'll wait till there's more information available.
