Vololights works purely on physical sense. Riders of a high torque sports bike may report different behavior of Vololights than a rider of a large cruiser- BUT in reality, for the first time in motorcycle riding history, deceleration indication is based on actual deceleration!
When we set out to design Vololights, one of the toughest question we had was in what condition should the lights come on? We know that
1.) It can't come on all the time as it would annoy and de-sensitize drivers.
2.) We have to reduce the "false positives" that comes from hard shifting and normal bumps on the road.
The first trigger point is meant to be a gentle reminder to the following drivers that you are decelerating and they should take their foot of the gas. Sportsbike riders can trigger this simply by letting go of gas at highway speed. Large cruiser bikes may not reach this deceleration trigger without shifting down a gear.
The second trigger point is designed to let the following drivers that you are decelerating at a high rate and they should apply brake appropriately. Riders with ABS will notice that this comes ON well before the ABS is activated.
We recommend asking your riding partner to check the function of the Vololights. If he/she finds that it is coming on too often or too little, you may want to recalibrate the product on a flat surface. Or you might want to adjust the sensitivity as shown below:
Sport - Least sensitive
Default - Ships in this sensitivity
Touring - Most sensitive
