Anyone who's ever done any bike riding in a big city knows that it's one of the more harrowing experiences of modern society. So, why not protect yourself as much as humanly possible? The VisiJax electronic cycling jacket seems like a pretty solid start. The neon-colored waterproof windbreaker features some 23 LEDs worth of butt-saving protection, with white lights on the front and red on the rear. The iMASS active signaling system, meanwhile, detects when the cyclist lifts his or her arm and triggers the corresponding turn signal. The jacket runs on three AAA batteries, which should give you around 200 hours of use. You can pick one up now in the UK for £129 (or £149 after May 31st).
