RSP 20 Function Wire Free Cycling Computer

Does what it says on the tin ,just don't have it next to electrical devices ie lights ,phones etc as it has a fit and before you knknow it you'll think your doing 100mph

Got this to replace a wired computer which never really worked. Found the instructions ok to follow once I'd realised the sensors had to be 2mm apart for the computer to work. Nice size font so I can easily read the settings when cycling and pretty accurate for mileage covered. Good value for the money.

Further to the post about the cycle computer giving out spurious readings, mine did/does the same but only when it is dark. I did a test this morning as I was walking up the railway platform at 2.5mph by switching on my front light, immediately the reading shot up to 10mph, going back to 2.5mph when I switched the light off !!

Having read some of the lesser reviews of this product, I would have to agree that I was confused by the extremely fast MPH readings that I was getting after first using the device - thought I had set it up incorrectly, but after reading these reviews, this would obviously not appear to be the case. The installing of the device on my bike wasn't particularly difficult and the components etc. look the part, but all pretty pointless if its not working correctly!!

Really fantastic little computer. Really easy to set up and in easy to use even whilst cycling. Really clear instructions on how to install, set-up and use.

The only bad thing I can say is that it is not strava compatible but for everything else its a fantastic piece of low cost kit.

Very easy to install, instructions clear and easy to follow. No trailing wires to worry about and great wireless reception unlike a previous wireless product i used to have!!

Great replacement for my lost cycle computer

Excellent Computer, Never had a problem with it since I got it in July, So happy with it that I'm getting another one for my Mountain Bike, Agreed with a previous review that it switches off after a set time, once you know this then you know to just switch it back on when you set off again after a long break. I have done several hundred miles on it so far without any probs. (Reviews are only a guide as different people have different perceptions of what they are buying or expect, for £20 this is well worth the money)

It started out alright but goes haywire frequently, gives strange readings for the top speed, i.e. 39 mph on a mountain bike. Gives different distances for the same route.
I would've thought that like many others that it would automatically work when you start pedalling, not so, if you stop for a break and exceed the standby time, it's very easy to start again without realising that it has turned itself off.
Very disappointed with this product.

This was not a good buy. It hardly ever works and is completely unreliable. wish I had bought a wired model.

Really great product, easy to fit to bike and seems straight forward to set the computer. Have recently purchased a second one to go on my road bike. HIGHLY RATED!!
