Lean Angle Calculation on the EatSleepRIDE App

Lean and Mean Angle Calculation

The EatSleepRIDE App is as diverse as the motorcycle community that it serves; many people say it's like five apps in one, and everyone is bound to use it differently. The data nerds among us tend to be most interested in getting their ride analytics.

EatSleepRIDE Mobile provides a highly secure platform for riders to record a wide range of data relating to bike performance, fuel economy, personal riding style, routes and locations, including calculating a rider's lean angle.

Lean Angle Calculation

We use internal iOS sensors to calculate a rider's position in relation to the road, which provides the lean angle calculation. Your lean angle is presented on a 180 degree scale: 0 to -90 degrees is your left lean angle. 0 to 90 degrees is your right lean angle.

If you see a wonky lean angle reading i.e. greater than 90° degrees or -90°, it may be due to an adjustment in the device's position when you're holding it in your hand just before or after your ride. Or maybe you're doing cartwheels on your bike, which we would be very interested in hearing more about.

Where should you keep the iPhone, iPad or iPod Touch to collect accurate readings?

Readings may differ based on where you keep your device; it's important to make sure the device is snug in a spot where it won't be moving around.

The most accurate readings have been taken when the device is oriented screen- facing-upwards, lying flat towards the sky in a tank bag. We also achieved some very accurate readings with the device mounted on the handlebars - just make sure you're watching the road.

Riders who subscribe to CrashLight can do either but it's best to keep the device in a breast pocket in the event the rider is separated from the bike in a crash.

How have you been using the lean angle, and what kind of readings are you getting? Let us know in the comment section below.
