SpeedX's Unicorn bike knows how much effort you're putting in
SpeedX is back with another "smart" road bike that promises to track your rides with a sleek, blemish-free design. The Unicorn is a sequel to the Leopard, which I took for a spin last June, and comes with a new, detachable bike computer on the stem. It has a 2.2-inch touchscreen and runs a custom version of Android, clearly indicating your current, average and maximum speed, among other information. Despite its color display, SpeedX says the new "SpeedForce" computer will be visible in direct sunlight and last more than 20 hours on a single charge. There's also a wireless button on the handlebars for convenient screen switching.
