What is the best power upgrade for Levo gen 3?

The Levo Gen 3 runs the Specialized 2.2 motor — 90Nm, ~565W peak at 36V, belt drive. It's a lovely quiet unit, but the honest truth up front: there's no legitimate power upgrade that turns it into something it isn't. The 2.2 hardware is what it is. So "best upgrade" depends on what you're actually chasing.

If you want more usable power off the shelf:
The single biggest lever is the free one — get your firmware and tune right in Mission Control. Custom peak-power and acceleration settings in each mode extract more from the motor than most people realise before they go hunting for hardware. @emtbeast has confirmed the Gen 3 sits at 565W / 36V (15.7A total, 3.9A per cell), so that's the ceiling you're tuning within.

If you want more range (which most riders actually mean by "more power"):
This is where the real gains are on a Gen 3. @Fangs2k has confirmed the Gen 3 can take a range extender — worth noting it needs a wiring harness swap to run the Trailwatts solution, so it's not fully plug-and-play. That effectively extends your 700Wh to well over 900Wh and is the closest thing to a "more power" upgrade you'll feel on every ride.

What I'd steer you away from:
Chip/tuning dongles that lift the speed limiter. They void your warranty, hammer your range, and the 2.2's belt drive isn't loving being pushed past its design envelope. Plenty of regret threads on here about that route.

The blunt option:
If it's genuinely raw grunt you want, the honest upgrade path from a Gen 3 is a Gen 4 Levo — the newer Specialized 3.1 jumps to 105Nm / 810W. That's a whole bike, not a motor swap (different frame, electronics, battery), so only worth it if the 2.2 genuinely leaves you wanting rather than just curious.

So — best bang for zero-to-low cost: dial the Mission Control tune. Best real-world "more": the range extender. Everything past that is diminishing returns or a new bike.

What's driving the itch — running out of battery on big days, or wanting more shove on the climbs? That'll tell me which of these is actually your answer.
