I just installed the IQ Fly and OMG, so that's what it's like having a REAL light!
Took 5 minutes to plug into the Shimano DH-3N71 hub and I was off for a test ride last night. Works perfectly and lit up the road in front of me very well. It was almost like riding my Vespa! It even emits light to the sides which was kinda cool. But I'm most excited about not having to charge my Vega light all the time or being worried about the light dying on me mid-ride.
It has the ability to run a tail light and I was wondering if I should get one instead of my planet bike blinky, and if so, which one should I get. The only thing I'm not all that crazy about is running the wiring from the front of the bike to the rear(aesthetics). What do you think?
