Need a speedometer for little wheels
Hey all, remember me? heheh. So I got a gas scooter just tonight off ebay and I'm lookin for a speedometer that will work with it's little wheels with only 80cm circumference (10in tall). Something must be around, anybody have an idea? I don't want to share my cyclocomputer on my bike with my scooter - it only goes down to a 100cm wheel size and I wouldn't want to mix my gas and bike miles anyways. Any finds?
Don't take me wrong ... this scooter is never going to come close to replacing my bike. I love biking. I thought this scooter was cool so I got it. And I can fold it up, stuff it in a locker or something at school, and take it home (if I'm lucky, it's not very compact). Plus I can take it to work without getting all smelly. I don't mind getting smelly when I'm on my bike, but I bet the boss would when I arrive!

One simple solution would be to mount two magnets on the wheel, this would double pulse the computer and make it think the wheel was 2x as large, then
enter a multiplier for a wheel 2x the size of your wheel. Just tried it with my
road bike and speedo reads 6mph with one magnet, 12mph with two. Put the magnets 180 degrees apart on the wheel. Steve

This should work.
Accepts wheels with a circumference of 1 mm to 3999 mm or a diameter of .5 mm to 127 cm (50 inches). The wired model is often used for non-bicycle applications such as motorcycles, karts, mopeds, scooter, road equipment, etc

Just roll out the wheels like a bike, then follow the directions to calabrate the computer.

[QUOTE=jump]lol ... no ... that would make it think that the wheels on the scooter has 1/2 the circumference. The ideal thing to do would have the speedometer pick up the magnet's field every other revolution, but that won't work unless I do some electronic work (and I don't want to cut up my probe). I could do that, but I'd end up with a permanent scootometer ... good thinking though ...[/QUOTE/]

That would probably work, but that Panoram computer looks like the ticket. Plus I don't want to use my bike's computer for this, so I'd be buying another computer anyway. Might as well get a Panoram.

I have the best answer. Get yourself the Garmin GPS and the handlebar mount. This will set you back $175.00 bucks but the GPS will tell you the speed you're traveling plus a whole lot more. I use mine all the time when exploring the MTA system in New York City. I ride the tain all the way to the last stop and the GPS just takes me home!

Hey look at that one! It's worthy too ... not quite as dashboardy as the panoram, but 1/2 the price ... hmmmm ... got me thinkin now ...
Don't forget about the Sigma sport BC800 it's about half the price of the Topeak Panoram. https://www.branfordbike.com/computer/comp3.html#item2
