I have used the Cat Eye Strada Wireless on both my Dahons and it works great. The wireless range seems to be better than most. And I have one less wire to deal with when I fold.
But yes, as energyandair pointed out, super bright LEDs can screw up wireless cyclometers. Mine go screwy when I run my Fenix L2Ds at Turbo mode. LOL.
My only complaint is that the Cat Eye Strada Wireless has gone up in price in my neck of the woods. I paid S$78 (US$52) for my early ones, and they are now S$95 (US$63).
Ouch.
