  • Electronic rev counter

    Has anyone fitted an electronic rev counter and do they just need a spark to operate or do you need a separate power source?
    Can anyone recommend a make?

        I would avoid the rechargeable one and use the version that has the 9v battery. The internal batteries only last a couple of seasons.

          Slightly off-topic, but you've got the right answer, so - is anyone aware of a self-contained GPS speedometer? All the ones I can see on sale need an external power supply, which is a bit tricky on a Villiers-engine trials bike.

          Any thoughts?

            Colin, Why not use an old Garmin sat nav? About 4 hour battery life, recharge in car, accurate speed reading. The older small screen probably last longer than the latest 5" screen and easier to mount. Colin

              If you just need a cheap speedo for a trials bike best idea is one of the cycle speedos available on line and from any cycle shop. You would need the wired version with a transponder fitted to the front forks & a spoke.
              Not GPS but cheap & effective.

                Yes John most trials riders use these from push bikes , although i would not worry to much at all with a trials iron, you are hardly likely to set cameras a flashing with a Greeves

                  Thanks for the comments, but I want one that actually looks like a speedo. There are a fair number of GPS speedos on offer that look like proper ones but all seem to need an external power source.

                  By the way, it needs to fit into a TFS binnacle...

                  Oh well...

                    I am putting a 12 volt battery in a cylindrical tool box with a plug in charger for my Ranger 3 project. I don't need it for the speedometer however it might be a neat solution as it would only be a couple of small wires and would not need charging that often, though always good to keep batteries on trickle charge.
