I have a Bontrager Node 2. It is wireless and will accept any Ant+Sport sensors plus read a power meter. I comes with a HR strap. It will display speed,HR, cadence, time, and temp all at once. The most power non Garmin cycle computer. Buy as much functionality as you can because upgrading is expensive. I have my old cycle computer in a drawer because I did not learn this lesson when I bought my first unit. Good luck.
