OpenLevo exists because your bike generates fascinating data and you should own all of it. Your data never leaves your phone unless you export it, and the app never shows you a number it can't stand behind.
Pairing, riding, recording, range, and tuning all work with zero network. There is no server because there is nothing a server should know about your rides. Your activities are files on your phone — exportable as FIT/GPX with rider and motor power as separate channels.
Your bike's serial number and your home location are excluded from every share and export unless you explicitly opt in. No analytics SDK ships in the app, and this website carries no trackers, no cookies, no fingerprinting.
Your rides are files on your phone, not rows in someone else's database. Export any of them as FIT/GPX and take your data wherever you like — the honest math travels with it, rider and motor power as separate channels.
These are settled decisions, written down, and guarded by automated tests. They will not be re-opened, and pull requests that cross them are rejected on sight.
No slider, no hidden gesture, no "debug menu". Removing the assist cutoff legally reclassifies your bike as an unregistered motor vehicle — illegal on trails and paths, voiding warranty and insurance, and shifting crash liability onto you. It also overruns the motor's thermal duty cycle. Worst of all, it's the single biggest reason e-MTB trail access gets revoked for everyone. No code path in OpenLevo writes the speed-limit parameter — and a regression test proves it on every release.
Settled decision D-001 · regression-testedThe protocol is reverse-engineered. Writing unverified parameters risks a configuration your dealer can't recover. OpenLevo writes only the documented tuning set — and reads every write back to verify it took.
D-002 · D-009Without a validated recovery path, flashing firmware can brick a motor. OpenLevo reads version information and nothing more.
D-003The rider stays in control. Every write requires a standing-still bike and an explicit confirmation showing exactly what changes. Nothing "optimizes itself" mid-descent.
D-005Every number carries its provenance — measured, derived, or estimate. Range projections wear a ~ and a confidence band that widens when the model knows less.
D-006Recording is phone-authoritative and journaled to disk as it happens. A Bluetooth drop, a locked screen, or even a crash costs you seconds of data, never the ride.
D-007Honest status, like everything else here.
