I am considering buying a cycle computer purely to get a reasonably accurate speedo reading. I read somewhere that the wireless variety might suffer from interference from the bike's electrics in some way - is this true? If this is the case, would the wired type be a better choice? Any other tips? Cheers!

every time I have used a wireless one , on several bikes they have been useless , numbers moving like a lotto machine! , wireless ones are getting harder to find now, if you want to try wireless aldi/lidl have some on offer next week about £6 ,

Even some of the wired ones can be disturbed by the ignition and just flicker around like mad. I fitted the cheapest cycle computer I could find on a 175 cc 2 stroke once, and it displayed up to 900 km/h even before I got the bike in 1st gear! The only time it was useful and gave reasonably correct readings was downhill with the engine stopped. I took it off again after a very short time. Can't rememeber the make and model.

I have had a Halfords wired one on my Francis Barnett for a couple of years now, it has worked fine, no problems at all.

I have had a wired version fitted to my Bullet for almost ten years. (Purchased from Lidl and a spare never used). I did try upgrading to a whizz-bang wireless model, waste of time, too much electromagnetic stuff going on. Stick to shielded wires.
The only issue; it shuts down if it gets too hot, I tried a sun shade, but then I couldn't read it..... Maybe not too much of an issue with UK weather?

Thanks for the info. If I decide to buy one, I'll go for a wired one then!

pretty accurate!

--------- OR, on any Sunday ( why does that sound familiar ?? ) just go full-bore past a speed camera van and note where your speedo needle actually is..... You'll have 2 things happen}----a) An automatic loss of pounds ( £ not lbs )-------- and b) A very accurate, printed record of what speed you were doing.......Using that knowledge you can now re-calibrate your speedometer.................Simples, fun and socially responsible !!...........and you only need to do it once..

I have a Tiny Tac on my 1953 Bullet and it works a treat but only gives revs. Wire wraps around spark plug lead and earth.

There are sites online where you can work out your speed and revs----http://www3.telus.net/modernmc/other/ratios.htm

Sory to be negative, but who on earth says that bicycle computer/speedos are accurate? Reasonably accurate? What the hell does that mean in real terms? This is like the people who believe that the speed shown on their satnav is more accurate that the vehicles speedo, when in fact it is often preferred simply because it shows a slower speed than the speedo. If you got a speeding NIP for doing say 2mph above the fixed penalty value would you dare to go to court and fight it on the basis of a bicycle digital device or a satnav? I bet nobody on here would be prepared to do that.
