CooSpo Realroad CS300

CooSpo Realroad CS300 GPS bike computer

The CooSpo Realroad CS300 GPS bike computer is a GPS enabled unit that will track all the usual metrics that us cyclists want. It doesn’t have any navigation features, but for the price that’s hardly an issue. CooSpo have been around since 2014 and produce cycling sensors, heart-rate monitors and gym software.

While we may be used to having full navigation features on our GPS computers, they’re often not needed. I know most of my rides are on roads I know well, so I don’t need any navigation. Having a simpler unit that just shows your ride metrics might be more useful for some riders. Consequently a unit like the Realroad CS300 will probably be just what some riders are looking for.


Open the box – all card packaging, well done CooSpo – and you have some nice white packaging. Unpack it and there’s the CS300 itself, a manual, charging-cable, tether cable, quarter-turn mount and mini bungees. CooSpo also have an out-front mount, heart-rate, speed and cadence sensors, which you can get from their store.

The outside of the CS300 is all plastic, with three buttons, a rubber-covered charging port and an attachment point for a tether cable. Once switched on you have four pages that you can scroll through, with a fifth one available if you want. Each page can be adjusted to show the data you want, although the layout stays the same. It would be nice to be able to select what kind of layout you see, as I often like just to have only one or two fields. This customisation is done via the CooSpo Ride app. I loaded it onto an Android phone and had no problems connecting to the CS300. Here you can record and review your rides and change settings. You can also start a ride recording on the app and follow it on a map, if you needed.

Dynamic Zone Chart

An unusual feature on the CS300 screen is a Dynamic Zone Chart in the top left corner. This can be set to display various metrics as zones on a radial display, could be useful for keeping you ‘in the zone’. The screen measures 38x52mm and uses tried and tested LCD technology to display your data. While it does look a little dated compared with newer units, it is easy to read. LCD displays also use very little charge, so battery life should be good.

The CS300 can connect to all the usual sensors using Ant+ or Bluetooth. So far I have only tried it with my watch, which connected straightaway. Hopefully my power-meters and other sensors will follow suit. So the CS300 seems like a straightforward basic bike computer for someone who wants to record their data while training. For more details check out the CS300 on the CooSpo website.
