Hey everyone, news of bike, motors, frames, bike, I ride a Turbo Levo Gen4 Pro.

Welcome to the forums, @anttohax. A Turbo Levo Gen 4 Pro is a solid machine to be rolling on, so let's get into what you're working with.

The Gen 4 Levo platform is built around Specialized's S-Works 3.1 motor (Brose-based), putting out 111Nm and 720W in its current firmware state. There was a notable OTA update that bumped the numbers up to 850W and 111Nm, so if you haven't updated yours yet, that's worth looking into as it's a free power unlock. The battery is the big 840Wh unit housed in that distinctive large flat downtube, though a 600Wh variant exists on some builds. It's a side-loading removable battery, which is a welcome design choice for home charging or swaps. Worth noting that in these winter temperatures, expect 10-20% less range than you'd get in summer.

Frame-wise, it's 150mm rear travel paired with a 160mm fork, running MX wheels (29 front, 27.5 rear) with a 64.5° head angle and 77° seat angle. The frame is rated for up to a 180mm fork if you ever fancy slackening things out further. @cañonaco weighed an S4 with the 840Wh battery at 22.13kg with a Fox 36, Hope brakes and BikeYoke dropper, so that gives you a ballpark for what these weigh fully built. @berglex managed to get a custom CEF55 frame build under 20kg with careful component selection, though sub-19kg was the ambitious target.

On the motor side, @jgusta noted the Brose unit feels mostly natural with no belts and plastic internals, which is one of its strengths over belt-driven systems, though there have been isolated reports of bikes shutting off mid-ride. If yours has been running reliably, you're in good shape. The Pro spec sits in a nice sweet spot: you get the same frame and motor platform as the S-Works without the eye-watering price tag (the S-Works complete runs around $15,400 USD / €14,500 for context).

Our database shows the S4 geometry as 480mm reach, 638mm stack, 435mm chainstays and 1254mm wheelbase, though I'd recommend cross-referencing with Specialized's official numbers as those entries are unverified.

If you're after specifics on component upgrades, suspension setup, firmware updates, or how owners are finding the bike long-term, I've got plenty more community data to dig into.
