Are there any reliable wireless computers that have the option to mount the speed pickup on the rear wheel?

You can do this with the Polar 720 as well. You must change the jumper inside the speed sensor so as to have a longer range (greater output)
How do you do this?Caadrider

I would love to do this, can you tell us how?
Here's how you increase the range of the Polar S720 sensorsglia

Remove the sensor from the bike. On the inside (what would be facing your fork) there are two small philips head screws recessed. Unscrew carefully. Then pull the plastic housing of the sensor appart. It contains a single board with electronic compenents on it including the little red light that flashes to test the sensor and the battery. (This by the way is how you change your battery when it gets low). You can get these at any CVS pharmacy or at Wallmart. You will see three pins, one of which (the inner one) will have a black jumper on it. However, it does not bridge any pins in default so it is just over one prong. You can move it over either to the two inner pins for medium reange or the two outer pins for maximum range. This will increase the power output and will drain your battery slighlty faster. You may need to replace it every 1000h-1500h instead of every 2000h (a small price to pay). Then reassemble and your done.
Best of luck!
