The Azur Z12 bike computer has all the basic ride data you could want at a very affordable price. This unit comes in both a wired and wireless version - the wired version connects the handlebar and sensors with a hard wire, which makes the performance much more consistent and reliable, and the connectivity a lot more stable. It also has a single battery that runs the whole unit, making charging a bit simpler. The downside of a wired computer is that the wires can feel a little messy on your bike. The alternative is the Azur Z12 wireless computer. Wireless computers are a little more pricey but provide a much tidier look and experience. Wireless computers run down a little faster so it comes down to personal preference.
