Hello,
What types of frequencies can be used by bike / cycle computers?
I’m trying to scan my Sigma RF bike computer without any success.
Any clues?

If I where designing this thing I would have used BTLE which is 2.4ghz but I didn’t design it and I have seen a few devices that were “odd”. A clue might be if your device is one of the versions that can be updated from your phone. it wouldn’t make a lot of sense to put two different radios in it when one could do the job.
It is rather simple device (no app-controlled): there is a sensor on the wheel (with magnet) and “base unit” on the steering wheel.

Lacking something better like an SDR and only using Flipper i would start by going to sub-ghz and use the Frequency analyzer near ther Bike device to see if it picks any frequency at all when in use/sending data from the sensor to the console… If Flipper can’t pick it up most likely it’s outside the frequency range that flipper do support… also google the exact model of device that you have to see if you can find the frequency and modulation that it uses …
Probably help if you shared the model info.
Hi, the frequency analyzer doesn’t detect any transmissions between the sensor and the console ;-(
Sure, it is Sigma BC 1009 STS (wireless).
