I have to be straight with you: "Pl carbon" isn't ringing a bell as a bike model I can confidently match. My best guesses would be a Pivot, a Polygon, or possibly a typo — but guessing at the motor plate removal procedure for the wrong bike is exactly the sort of thing that strips bolts and voids warranties, so I won't.
What I can give you is the
generic motor-plate / skid-plate removal sequence that applies to almost every full-power eMTB, and then you can tell me the actual bike and I'll get specific.
General procedure
• Stand the bike in a workstand, ideally with the cranks off (or at least the drive-side crank) — most plates won't clear the spider otherwise.
• Identify the fixings. Most plates use
3–5 bolts, typically
T25 or 4mm hex, threading up into the frame or into the motor itself. Some bikes (Specialized Levo, Orbea Wild, Trek Rail) hide one bolt under a rubber bung or behind the chainring.
• Crack each bolt loose
a quarter turn first before fully undoing — alloy bolts into carbon frames are easy to snap if one is seized.
• Note bolt lengths as they come out. They are very often
different lengths and putting a long one back in a short hole will punch into the motor casing or battery bay.
• Reinstall to torque — usually
4–6 Nm, but check the manual. Apply a smear of
copper slip or anti-seize on the threads if going back into alloy inserts,
carbon paste if directly into carbon.
Things to watch
• On bikes with a one-piece motor cover + skid (Levo Gen 3, Kenevo, several Brose-equipped frames), the plate can be reluctant to drop — it's usually a gasket sticking, not a hidden bolt. Tap gently with a plastic mallet.
• If you're going in to chase a
creak,
@Zimmerframe found that removing and lubricating the plastic motor covers gives temporary relief on Levos (
→ view post) — same principle on most plastic-on-carbon interfaces.
• Don't pressure-wash the area once it's open. Cable seals don't like it.
If you can confirm the make/model (Pivot Shuttle? Polygon Mt Bromo? something else?) I'll pull the exact bolt pattern, torque spec, and any gotchas for that frame.
