    Are they all equal?

    Just pieced together an old spesh wired computer, but waggling a wheel magnet of unknown provenance past the sensor is registering nothing.

    I suspect it’s the sensor that’s knackered? 🙁

    A magnet is a magnet…

    Yeah magnets are magnets in this situation.

    Yeah, I felt stupid asking the question! Just at a loss why a wired sensor (reed switch?) would pack up.

    Oh well, arse.

    Are you just looking for a basic wired one for speed?

    I am a cock, just in case it was ever in doubt.

    I was getting frustrated as to why it wasn’t working, so unraveled the whole cable.

    “Huh. That’s long”

    *brain ticks over ever so slowly….remembers last bike it was on*

    “Oh”

    It’s not a wired computer, it’s wireless.

    I’ve been cleaning contacts, holding the wired sensor up to my ears and general mucking about…..against the cadence sensor.

    Found the wireless sender for forks – worked straight off.

    Nob.

    However, I only have a wheel magnet – does anyone have a crank arm magnet thing please? I never took it off the last bike this speedo was used on (can you tell I haven’t ridden for some time?)

    Ta 😳

    I lost our running total milage for my “round the world” trip by standing next to a huge substation in Australia. It added 15,000km in a couple of minutes 😆

    I just used a rare earth magnet i had kicking around and it just sticks to the pedal axle.

    I don’t think i have any left but I’ll look.

    that some kind soul my have one in their spares box.

    Used to have one but stuck it on a friend’s bike as an ‘extra’ – he thought he was going twice as fast as he was 🙂 . Amusing when he found out

    As above, any decent small magnet. You can put a wrap of tape around it if it won’t stick to your crank or pedal spindle. I’ve got a spare spoke-mounted one (somewhere??) if that’s any good
