Rated 5 out of 5 by from Easy to install, simple to use Went through other bike computers (wireless, more whiz bang features, and more expensive)and realized all I needed was speed, distance, average. This fits the need perfectly and at a great price. Very easy to install. The preset measurements for wheel diameter were very accurate. Liked the simplicity of the screen layout and the information it provided. Bought one for my wife's bike as well.

Rated 5 out of 5 by from Simple, easy to use I opted for Velo 7 vs. the Velo 9. I didn't think the extra $5 was worth counting calories and the carbon offset. The computer was simple to set up and seems to be accurate. I'm mainly concerned about how far I go, how fast I am going, average speed, and the time elapsed during my ride. This computer does everything I need without any frills.

Rated 4 out of 5 by from Simple, it works I just needed the basics (speed, trip distance, average speed, odometer) and this does the job. As far as I can tell it is accurate - I calibrated it by entering the distance covered in one wheel revolution, rather than rely on the tire size. Installation was straightforward. It uses zip ties; although they work I'd prefer a better mounting mechanism, such as bracket + bolt or similar.

Rated 4 out of 5 by from No frills, easy to install and accurate The one I had used previously was wireless and after reading some blogs I realized that some crazy speed readings I had received were not an isolated incident. This unit was cheaper, was easy to install, and provided all of the basic features that I needed. This wired unit also seems to be more accurate so losing the wireless unit was a blessing in disguise.

Rated 3 out of 5 by from It works Easy to use, clear display, has all the basic functions other than GPS, cadence, or power-meter. It's already been in the rain a few times and no issues. The price is right. One thing to note is it doesn't seem you can set the odometer. I go through bike computers and batteries and would like to be able to set the ODO to the last known mileage on the bike.

Rated 5 out of 5 by from Decent Value Great price for a basic device. It is made much more cheaply that the Cateye that it replaces however it is much easier to use and the size of the display is much easier to read. I've only had it a month. Time will tell if it will last as long as the old model

Rated 5 out of 5 by from okey mokey I wanted this, & after receiving it, I figured, wait, I don't need it and I don't want it, because it'll get in the way of my enjoying the ride. It might turn a ride into a desire to perform better every week or month, when I realize that I don't want to do that. I'm only built for speed going downhill and for hitching a ride up if it's too long or steep. I just want to enjoy riding. My smartphone with a cycling app (S Health) will track my route, speed, etc IF I want/need. My map app will take me home if need be. This computer is another doodad that will just own me. That said, I did play with this and found it easy to install & set up for my bike. Information? Enough and too much. Durability? I'll not ever know, if I take it back to the store.

Rated 4 out of 5 by from great to look down and see current information! I bought this a month ago. It was very easy to install and calibrate. I've loved having real time information available to glance down at.

How long is the wire? I'm trying to figure out if I'll be able to put it on my back tire rather than front? Thanks!

Asked by: mjramaker
The wire is not long enough to reach the back tire.

Does the CatEye Velo 7 bicycle computer have a compass? I don't see it in the specs, but a little arrow appears on the product's picture. 

Asked by: gerardopatroncano
This cyclometer does not have a compass reading. What you are seeing is a pace arrow. It indicates if the current speed is faster or slower than the average speed.

Is there a limit to the number of miles the odometer can accumulate? My 13-year old Sigma just stopped at 20,344 only because the wire finally broke. I'd like to add that in & keep it going. I noticed one other computer that topped out at 999.99 miles. 

Asked by: raybob
The CatEye Velo 7 bicycle computer odometer will record up to 99,999 miles. However, it does not allow you to manually enter odometer miles, nor does it retain them when you change out the battery. The lowest-priced, wired computer in CatEye's line that does allow you enter odometer miles is the Cadence.

I see that the speed is shown in km/h. Is there an MPH option?

Asked by: RachelF
Yes, MPH can also be shown. A manual is available on the CatEye web site to see how to make the change.

Is the sensor/wire/mount supposed to be included? Or does one have to purchase the accessory kit as well to actually use the computer?

 I'm interested in buying this wireless computer for my spin bike. Will it mounted on a spin bike?

Asked by: Sasspin
This bike computer is not wireless. It is a wired computer with sensors that are designed to take readings from a rotating front wheel. It will most likely not work for your spin bike.
