There are a handful of spoke LED devices out there which use persistence of vision (POV) to show designs. The Monkeylectric monkey light is perhaps the best marketed and looks like it's actually pretty decent, but the price is prohibitively expensive for those looking to just experiment.
Hokey Spokes are cheaper, but more.. hokey.. lol.. not nearly as cool, and with some of the *really* cheap ones on the market today, almost seem like they are outdated.
Then there are the cheap chinese ones all over ebay for ~$10.. or some even cheaper that go on the valve stem. Those $10 ones dont look like they would stand up to much use.
I've been interested in trying out some of these devices, but it seems like you need at least 2 or more to get a full wheel, and it seems like they only display on one side, so you'd have to have a lot to get a full wheel on both sides. the cheaper ones seem to be only one color (or static multicolor, ie not changing colors)
Anybody have any of these devices and care to offer a review? Mostly would be using them for social rides, not continuous use
