Biking is usually touted as a wonderful, healthy activity—and with good reason. Cyclists get good exercise and reduce their carbon footprint in the process. Plus, it's just a fun way to get around. It can't be possible to make bicycling even better, can it? The British erotic store Sexshop365 apparently thought so and, accordingly, devised its appropriately named vibrating Happy Seat ($44.89 plus shipping). Yes, it's essentially a vibrator for a bike seat. So, exercise, save the planet and get happy while doing it. Safety issues aside, it's a sure thing. www.sexshop365.co.uk.
