The Lumotec IQ Fly is the less expensive little brother to the IQ Cyo.  It features the same technical advances, but with slightly less output and a lower price.

Light is provided by a high power LED so no bulb replacement should ever be needed.  The LED should last many thousands of hours.  The LED will come to full power at slower speeds (<5mph) and be brighter than a halogen.  

We stock the Plus version and the Senso Plus.  The Plus has Busch and Muller's "Standlight" feature.  Standlight is a condenser that is charged while riding so that when the bike comes to stop the light will stay on for several minutes.  Standlight uses no batteries and requires no maintenance.  The Senso Plus version adds a light detecting sensor that will turn the light on automatically when it is dark.
