Speedometers

If you are attracted to the cheap bike speedo currently on offer in ALDI stores (6th May)do not bother, it cannot be set low enough to suit the wheel sizes we use. Can anyone recommend one that can be used on 5" wheels?
Thanks, Colin Edmondson 4443

Malcolm High of Model Engineers Laser was offering suitable speedometers for our purposes. I don't know if he still does, might be worth checking out his website.

Stick with the aldi bike speedo and add extra magnets on the circumference of your sensing disc. Magnets from intruder alarm contacts are ideal. Mr Pythagoras can provide the number required

Don't forget to put a red marker on the display to move the decimal point so you are doing 9 mph not 90 mph

Another option is to use a satnav, no wires to worry about. My second hand one reads mph (and height too!)

Hallfords can supply suitable cheap cycle speedos, I have several on various rolling stock.

Yes, I spotted the typo, but too late!!! A case where being able to edit posts would be better.

I did of course mean Halfords.

The best answer that I can think of is that I'm no longer the Editor!!! lol.

In fact Halfords is correct, not Halford's

Could be known as Half Rods of course!

My remark was In Defence of the Ex-Editor! It was John's rejoinder which sparked it off! Oh! Bother! It doesn't matter!
Far too many exclamation marks here....

The cheapest one from Halfords (ca £10) does good service on both my Hunslet and Manning Wardle, each with wheels of about 5". The acned youths in the shop don't really understand, but you should be able to dial in a wheel circumference of about 160mm. and get away with it. If not try a 10X multiplier and kid yourself you are doing 100 mph. The correct value has worked for my two samples separated by 12 years.

Thanks for all your help. I bought the £10 Hallfoorddss!!!(excesses of everything in just one word). It can be set straight from the box to suit 5" wheels, it is square and black and looks the part. Thank goodness it doesn't feel the need to tell me how many calories I have burnt like some of the expensive ones! Cheers, Colin
