I think with Monkeylectics and other wheel lights the emphasis is more on providing a side show. My purpose is just to get me seen. I wish there were more choices. The rimfires work but I could wish for something that is more easy on / easy off. Real important to have a battery compartment that blends more with the bike and creates no "wheel balance issues". It would be nice to have the battery compartment made to clamp around the hub of the wheel and yet cause no balance issue. Better to have the batteries horizontal ( with the hub ) and preferable with Li-ion cells. I like the rimfires as "proto-type" but I'd like something better engineered. I would also like to be able to choose the color of my LED's. I don't want so much of a show I just want to be seen.
