A Sisyphe creation
Your iPhone becomes
your bike's dashboard.
Live lean angle, route corners colored by your speed, danger zones announced, and a summary of every ride. No account: everything stays on your phone.

MotoLean is coming soon to iPhone. The app is currently available in French only. Write to us to be told when it launches.
Features
Designed for a handlebar-mounted phone
Numbers you read at a glance, colors rather than text, and large touch targets you can use with gloves on.
Live lean angle
The iPhone's motion sensors measure the bike's angle, left and right. One calibration is enough, as long as the mount doesn't change.
Corners ahead
On a planned route, upcoming corners appear on the map and change color with your speed: green, orange, then magenta when you need to slow down.
Danger zones
Zone entry and exit announced, speed limit shown, audible alert when speeding. Based on French road-safety open data, presented the way French law requires.
Navigation
Search for an address or a place: MotoLean plots the route and guides you on a tilted 3D map with the camera behind you — or a top-down view, your choice.
Gas stations
Nearby stations show up as large markers you can spot at a glance, on the home map and while navigating.
Ride summary
Distance, duration, average and top speed, maximum angle on each side, and the track colored by lean: slide your finger along it to relive the ride.
GPX export
Every ride exports as a standard GPX file, ready to import into Strava, Files or any other mapping app.
Riding tips
Lines, braking, anticipation, gear: simple pointers to take corners better and progress with confidence.
Suitable speed
A bit fast
Too fast for this corner
Corner speeds are physics-based estimates (curve radius, dry or wet grip), not guaranteed limits: they replace neither road signs nor your own judgment.
Under the hood
