Mountain Bike Ride

Here's a great example of the varied and detailed information logged from a short mtn bike ride around Los Alamos, NM. The logger board was worn in a small hydration backpack while a wireless g-force sensor was placed on the handlebars of the bike. The bike used had a front shock with ~3.5" of travel, and a small ~1" shock in the rear.

Note the difference between the shocks received on the handlebars to those of the rider, showing how much of the vibration is absorbed by the arms of the rider. There's also a direct relation between speed and the magnitude of the shocks to the bike.

The track can be viewed in Google Earth by clicking here. The color of the track indicates the speed. A combination of bike g-forces and speed were used to give an indication of how bumpy the trail was, and is displayed with smoother sections lower to the ground, and bumpier sections higher from the ground. You will need to tilt your view away from vertical and zoom in to see this.
