My first try with the FOBO Bike tyre pressure sensor (gift from my salesman who doesn't need it on his scrambler) and I configured the average tyre pressure as 32.6psi (front & rear). I have not touched the tyre pressure since the bike was bought. Looks like this bike is way over pressured. It is possible to release excess air by merely unscrewing the sensor which I did then clear memory and it gives the latest reading. Still, I recommend doing it next to a tyre pressure pump because you can over zealously release a bit too much... like me. Fortunately the petrol station is 5 lanes away. If you rarely use the bike, the sensor is ideal for checking tyre pressure.
