Smart City Bike Lights conserve power, but brighten when it’s essential to alert drivers to a cyclist’s presence. Accelerometers monitor various conditions including swerving, sudden braking, road surface condition and falls. City planners are using this data to improve road safety, cycle track planning based on desire lines and reducing surface repair costs.
