Digital speedo, GPS speedo and certifications?

No shit sherlock, what was your first clue? We also need to remind us that it depends on whether the speedo is turned on, has batteries, isn't drowned in water, and that we also need to avoid solar flares. Any other obvious shit we've missed?

It does seem silly but you'd be surprised.

I have seen pushies with this type of speedo fitted where they have just been left at the defaults, or set up for a rim size not tyre size. Then they pat themselves on the back or berate themselves over their top speed.

Like any tool / measuring device, only as good as the operator.


I do not wish to cast aspersions about someone I have never met bit most people on here would tear in and get it fitted, probably try it out and post a review before they got around to the instructions.


Ergo saying they are 100% accurate is subjective at best.

Setting the speedo up for our electric bikes was a pita!
Bloody cheap chinese electronics with no instructions worth a damn!

I can see why a lot of people leave them on default and hope........

Generally they recommend chalking your tyre and the ground with one stroke. Push bike forward in a straight line two rotations and chalk level with mark on tyre. Measure and divide by two. Input this into the tyre size.

Not sure which one? Just cycle through inputs until you get to one with one integer a decimal and two or three more integers.

Hi I have just fitted an Acewell to an old Beemer , I ordered the sender that fits straight in to the gearbox but it came with a magnet type sender for your front wheel , bit pricey around $400 but does revs, oil/water temp all the lights and indicator stuff as we'll . I got it from S3 performance in oz
