I have a cateye velo 7 wireless computer on a Hybrid bike and I use it mostly to check the speed and track my miles like an odometer. I love it, its simple and cheap and works.
I recently got a road bike that I am going to use on the weekends and but I want the same computer to track my miles. It is possible to have two sensors on two different bikes and use the same computer?
the wheel size on both 700C
It depends on the bike computer.
Some computers have this feature, others don't. A brief look at the manual of this computer says yours only supports one bike and you'll need to get another computer for the other bike (or recalibrate it each time you swap them). If the tire sizes are the same, you might be able to get by by just swapping the computer between two sensors of the same type, but there may be enough sensor variation that the results may be off by a measurable amount, so I wouldn't recommend that. If the tire sizes are different, you'll obviously need to either recalibrate or have the computer have settings for 2 bikes since the circumferences are different.
In any case, you need 2 sensors, and if you're using a cheap bike computer, the cost of the other sensor will be close to getting it with another of the same bike computer.
I have been using Cateye Mity 8 for my 2 bikes. It has a dual bike function, where you can select Bike A or Bike B. Upon setting up, you can specify the tire sizes for respective bikes. Odometer count is for the total mileage done on both bikes. However, there is a trip meter which tells you the distance for the current trip, independently for Bikes A and B. Not wireless, no backlight. Odometer can be programmed i.e. you can set the odometer count (say for transferring the odometer count from previous cyclomemeter).
I have a GPS/watch/activity tracker/HR computer that I wear on my wrist. It will connect to the two cadence sensors I have on two different bikes, but measure speed/distance/HR on ANY bike I ride. The newer wrist enabled GPS/HR stuff is spendy, but much more flexible than older style setups using a computer designed for X number of bikes. It also connects to the manufacturer's website which allows me to track the totals from any activity and/or the mileage on individual pieces of equipment.
If the tyre sizes are the same there is no reason you can't just get a second wiring kit and swap the computer between bikes. The computer won't distinguish which bike you rode but you'll be able to keep track of total mileage. A wiring kit like this would do the job:
(for example, from fawkes cycles)
If you have different sizes of tyre on each bike then the mileage captured would be inaccurate.
There are several bike computers that support different settings for two bikes. Cat Eye Velo 7 is not one of them.
