I was walking through Target and saw a $10 bike speedo. Says it goes up to 99 miles an hour measures distance, time, etc... I get it to see if it works on my ped. It does! So sweet! The only downside is that it takes a measurement every 4 sec., but for $10! I would definently recomend. Will use on all my ped projects from now on. Just make sure there is only 1mm between the sensor and magnet like it says in the directions. Just thought I'de share.
Bump.
cool, cheapest i've found so far was twice that.
we got a bell brand one, it would only read upto 30mph, even when she was clearly doing 35 by pacing against my car.
i got two free speedos from frosted flakes
I got an $8 speedo at Kmart, works great.
I purchased one of the $8 Bell speedo units at WalMart for my Solex 3800.
The magnet-to-sensor-distance issue is a total joke, once you see how the magnet is fixed to the spokes. The magnet will make it a few revs before it shifts and possibly collides with the fork, Maybe this setup works on normal bicycles, but not on a Solex.
I might make my own wheel magnet for this speedo setup, but I wouldn't buy another one to install on a ped..

Mine works. I JB welded the magnet and just ziptied the sensor a few times.
i think i saw one of those at target and was wondering how it worked.
thanks for the heads up, if i decide to not go with the stock speedo thatd be a nice, small replacement.
Pics of setting it up? And is this in the bike section at Target?
shit is cheap for a reason. It usually sucks
I got the same target $10 speedo, and then picked up an 8lb "rare earth" magnet to replace the cheap magnet that came with it. Works fine, the stronger magnet allows for about an inch gap before the magnet stops closing the reed switch.
I almost always either brake, or disconnect my speedos on my bikes.
When I want to see how fast I am going I can just GPS myself.
"shit" is cheap cause little kids in indonesia make it.
Yeah, that's the plan over here.. I've got a pile of Neodymium magnets and I'll figure out the best way to fix one to the spokes. Good to know that it works out!
What's so silly about this, is that the issue with the spoke magnet is one of design - not manufacture. If they'd just change the design a bit, it would work fine.. and it wouldn't cost any more to manufacture them.

I don't have pics now but can work on that. Yeah I found mine in the bike section.
A junkyard bike I found had what looked like a first-gen Trek digital speedometer on it. I took it off to use on a different bike, and when I went to remove the magnet I was really impressed; the magnet was just a little circular one, but it was pressed into a slotted metal cylinder that was tapped for a little bolt.
I can see why this changed; heavy bicycle parts don't sell. Still, the vintage Trek one only _looked_ heavy - it was rock-solid, and outlasted the bike it was on.
To those with the rare-earth, and neodymium magnets: just remember that putting a super-strong magnet on means you have to watch how you park your bike.
If you park with the magnet right over the reed switch coming off the speedometer, you'll magnetize it. Once its magnetized it won't ever work right again (or it won't work at all).
This is also why you shouldn't really buy a used bike speedometer - most of the time, people take one off a bike and just put all the parts in a ziploc bag, which eventually destroys the reed switch.
I thought you were talking about speedo bathing suits. Of course you go faster just wearing them!
HA! erica, i thought the same thing. thats why i didn't open the post yesterday. i thouht it was some guy being funny. now i get it...
Nope just Speedometers. lol.
