Tunturi Emullet 2025 — upgrading to a full suspension frame with Shimano motor?

My bike is a Tunturi Emullet 2025.

Upgrade full suspension frame shimano motors.

Let me make sure I've understood what you're after, because "Upgrade full suspension frame shimano motors" could go a couple of ways — and I'd rather get you the right answer than guess.

Here's what I can pin down and what I can't:

Your bike — the Tunturi Emullet 2025
I don't have verified spec data on the Tunturi Emullet in my local database, and Tunturi isn't a brand that crops up much on here (it's better known in the UK as a fitness/exercise-bike name, so the eMTB line is a bit of an unknown quantity in these parts). Before I send you down the wrong path on a frame or motor swap, I'd want to confirm:

• Which Shimano motor it actually runs — EP6, EP8, or the EP801. That matters a lot for any upgrade conversation, because:
– The EP6 (DU-EP600) is 85Nm / 500W peak, cast-aluminium housing.
– The EP8 (DU-EP800) is 85Nm / 500W peak, magnesium.
– The EP801 is the same 85Nm but 600W peak via firmware, with Auto Shift and Free Shift support.
All three share the same 85Nm torque, so a motor "upgrade" between them is more about firmware features than raw grunt — the EP801 firmware (latest is 5.3.2, per @kla456 → view post) is the one worth chasing if your frame's wired for it.

Now — the bit I genuinely can't answer without more from you:

"Upgrade full suspension frame" — do you mean:
1. You've got the Emullet and want to know what's worth upgrading on it (shock, fork, drivetrain)?
2. You're looking to move to a different full-suspension Shimano-motored frame and want recommendations?
3. Something about swapping the motor itself?

Each of those is a completely different answer, and a couple need me to know the exact motor and rear shock size your Emullet uses (Tunturi don't publish that as freely as the big brands).

One thing worth flagging if it's a drivetrain upgrade you're after: Shimano's XT Di2 M8150 was designed around the EP6/EP801 motors, so it's a clean match if your bike runs either — @HandsomeDanNZ → view post makes that point well.

Tell me which of those three you're after — and the motor model and rear shock size if you've got them to hand — and I'll give you something concrete to work with.
