I would like a new cycle computer. I have done some searching on-line but I think I am confused about what some of the terms mean in the descriptions.

These are the characteristics I would like it to have:

Handle 2 bikes including being able to set the tire diameter for each bike
Have settable odometers for both bikes and for lifetime mileage
Be waterproof to the extent it works in the rain
Auto start and stop when the bike and I do
Have a trip timer and average speed for each ride (doesn't need to store that information)
Have a backlight
Be able to display current speed (with comparison to average), elapsed ride time and one other line of data through which I can scroll additional data including; time of day, average speed, bike odometer, lifetime odometer, temperature, maximum speed

I would prefer a wired computer but would accept wireless.

I haven't been able to find a cycle computer that I could tell had all of these features.

I am looking for recommendations.

I have two Garmins. They are horrible at the start and stop conditions I ride in in the city so no, a GPS unit is not a good answer.

If you use a wheel speed sensor (wireless), you may resolve your issues with "horrible at the start and stop conditions." Tall buildings and park tree canopies can cause havoc with GPS reception. Wheels speed sensors fill in for that short coming.

And with a GPS computer in open area not influenced by buildings and trees, the head unit can auto calibrate the wheel circumference.

I like my Garmin bike computer. I currently have an Edge 820.

I was looking at the settings on my Garmin 820. I noticed on the auto start/stop, it does not start until you get up to 6 mph and it cannot be set any lower than 6 mph.

I just re-did the settings on my Garmin Edge800 so that I don't have a minimum start speed (less than 1 mile per hour) Like others said it automatically calculates my wheel circumference and uses that. I check to see if it is working by spinning the wheel.

That is strange, I have my 820 set at 4.0. And when I go to the settings, I can choose my speed auto start.

I have a couple VDO MC1.0 wired computers that do most of what you want. Experience from my conventional cyclometer days showed it easier to have a dedicated computer for each bike, but the MC1.0 will handle two wheel settings and maintains several different odometers. I never challenged water resistance; easier to simply put a plastic baggie over it when it rained.
It does NOT have any screen illumination.

I started using GPS about 10 years ago (Garmin Edge) and abandoned the wired computer about 8 years ago. Today I use a Wahoo Elemnt and love it. As others observed, you can skip wheel calibration altogether and just put it on the bike. It even works in a back pocket should you find yourself on a borrowed bike or want to expand your GPS tracking to other endeavors such as running/hiking.

Wahoo doesn't have the same capability to maintain individual bike data that the Garmin Edge has, but I've learned to let go of some obsessiveness and just enjoy the ride. The Wahoo auto feeds any number of cloud based tracking sites which allows me to keep track of equipment life (tires, chains, etc). I use Sport Tracks for that. The one thing I wish the Wahoo did better was to allow me to touch a button to illuminate the backlight without activating the button function.

One of the VDOs currently reside on my wife's bike, but the other is looking for a home.

Let me know what I am doing wrong, because mine sure won't take anything below 6 mph.

I have both an Edge 500 and an 820. I will have to play with the settings a bit more but the way my 820 is configured the display just shows elapsed time since the start of the ride. It only stops if I manually turn off the device.

The 500 does a better job but it still has a tendency to start up again with the type of GPS drift that occurs in an urban area even if there is a wheel sensor which now costs more than one of the more basic wheel sensor computers.

The VDO line of cycle computers look very promising. What does the auto start/stop being based off of motion sensor do compared to stopping after a set number of seconds if the wheel magnet hasn't passed the sensor on the fork?

Also, where does one get VDO cycle computers? It looks like the US distributor is in Ventura, CA.

I have never gotten that issue. I just went in and changed the minimum speed multiple times to 1.0, 2.0, 3.0, 4.0, etc and it took every one.

First I suggest doing a soft reset that does not delete any information on your unit.

www8.garmin.com/manuals/webhelp/edge820/EN-US/GUID-46A06A7C-1F46-4DBA-B010-DAD7BA6BE59E.html

Then again try to set your minimum speed

I found the manual for the Velo 9....
www.cateye.com/intl/support/manual/data/doc/CC-VL820520_Odo_HP_ENG_v1.pdf

I've always liked Cateye computers. They always used to have two tire sizes for bike A & B, not sure if they still do. They check all your boxes except backlighting.

Let me check to see if I have an old Mity 8 I no longer use. If I do I'll give it to you. I know they have bike A&B wheel circumferences.

I have a cateye wireless that has worked flawlessly for many years. I believe the functions meet your requirements. The price is easy on the pocket book too.
