I used to use that set up, I’m assuming it is the magnet and sensor set up.
Make sure battery is good.
I suspect the issue may be related to your sensor and magnet.
The spacing between the wheel and the frame tends to be a lot more on a MTB vs a road bike.
You may need to move sensor closer or get a speed sensor that attaches to the hub of the wheel.
I think you could still use the old one for cadence
Thank you for all the replies. I’m going to show the height of technical ignorance as I plod on.
Regarding the CooSpo drivers link, I don’t know how/what to download when I extract all the Zip folders. It talks about USB driver update but I don’t have a USB dongle? Just a complete novice here.
On my mobile Bluetooth setting under Coospo it says “an app is needed to use this device”.
Thanks
Samuel,
Have you downloaded the CooSpo app called Coospo Ride app to your phone? Let’s start and make sure the BK8 is functioning. Next is your laptop upgraded to latest version of Windows it is capable of handling?
