Bicycle riders generally have little suspension available to them to cushion rough city roads and paths. Impact from the road surface travels right through the bike and is absorbed by my arms, legs and saddle. This contributes to fatigue but often occurs unconsciously as the act of navigating through traffic demands persistent attention. I wondered, just what forces do I experience while riding?

The vibration I experienced while riding a bicycle was recorded over several months using sensors and a mobile phone. The visualization will display an aggregate of the largest forces as well as a detailed view of individual rides.
