Bicyclo Speedo
I know this has come up before but need a bit of clarification....do bike speedo's pass SVA? If my speedo ETB isn't calibrated right can
I fit a bike (as in push bike) so that it'll pass SVA? Also if doing this does the speedo need some kind of back light?? If so anyone know any
good ways of building one in....do the wireless one's work other that big a distance? I can get them cheap from work so don't mind too
much having to pull one apart.....Cheers in advance...and sorry if some of this has been dealt with before....Oli.

You'll need illumination of some sort and a trip meter that can't be reset. Wireless ones have a very limited range, and are affected by
all sorts of crap. I've lost count of the times my Mountain bike one has had a hiccup. (cateye cordless).

Does anyone know of any (legal) way of checking if my speedo is calibrated properly before SVA??? Not gonna do an MOT or rolling road before
either....Should be OK as it was supplied by tiger along with the diff, gearbox, engine and wheels! Haven't changed anything but you know would
be slightly miffed anyway! Cheers Oli.

There was a spread sheet on one of the forums that gave diff, wheel and tyre combinations and speedo turns per mile for ford based cars, that allowed
you to work out revs per MPH.I jacked the back of my car up on axle stands and ran in gear to allow me to check the speedo against the rev counter.It
appeared to be reading slow and when i had it tested it was as the spread sheet showed, I just moved the needle around by a few mph to get it
passed.
If trying this method just be carefull to jack up carefully and chock the front wheels securely.

Buy a bike speedo to calibrate the car one, as long as you measure the circumference accurately along the ground with normal tyre pressures and
occupants they are super accurate, circa 99.9%, all you need to do is make sure the car speedo is showing a slightly faster speed than you are
actually doing, as it won't pass if it is showing on the slow side.

Yes you can use the megajolt , just connect it to your Laptop and log onto the runtime screen , the Rpm is shown on there.
