Title: Bike speedo
Post by: Vegasrandall on March 31, 2011, 09:05:38 PM
My odometer quit shortly after buying the bike.my best option until I had the $$ to get the unit rebuilt was a bicycle speedometer.
A sigma 509 is very easy to install and gives you time,speed,and distance.I used a small magnet about the size of a hearing aid battery it sticks to the rotor rivets quite nicely at all speeds.to act as a trigger for the pickup lead for the speedo.
Cost here from REI was $24.00

Yep!  I've got one of those too.  Works great.  

I got one mainly because the odometer is reading about half.  Now I know for sure it reads a little less than half.  And I've found out that my speedometer is really close but reads a little high at lower speeds, right on about 50 mph, and a little lower at higher speeds. (or the other way around, I can't remember right not)    ::)  That I don't understand.  Anyway, I find I'm using the bicycle computer now to check my speed.   But you can't be watching the speedo all the time and I've surprised myself at the end of the day when I check out the top speed of the day.   :o   ;D  I like that it gives you trip mileage, the highest speed and the time spent riding.

I found that 2 of those little rare earth magnets stuck together in between the rotor rivets work great.  To make sure they stay where I want them I added a spot of super glue.   They've worked great for a few years now.  Although I found this year that I needed to reglue them on and they've collected lots of little iron fibers.  Makes it look like a fuzzy creature stuck there.  All cleaned up now.

My magnet, too, Melena, with the Vapor's trigger. I used a big, powerful magnetic pick-up tool to clean off most of the brake pad fuzz. Now then, how do I get the fuzz off my pick-up tool? :-X

You need to use a powerful electromagnet.  Turn off the power, off falls the fuzz!

 ;D  Yeah!  I get that one.  Hee hee!  I just picked it off with a paper towel and still didn't get it all.  But got most of it.  I didn't think about using my magnetic pick-up tool.  Now I'm glad I didn't!   ;D

Rob, your idea is a good one.  But I liked Monte's joke.   ;D

Oh ho! Melena's done swept out the Winter Doldrums. :)

Actually, I've always used a piece of duct tape to pull the fuzz off the pick-up tool and Vapor magnets.

Stay sticky, my friend. [smiley=beer.gif]   Monte

Yeah!  The winter doldrums left suddenly.  I don't think they like the light of that big round object in the sky.   ;)

Now why didn't I think of that.........Duck Tape.  That's another reason why I love this forum.  Always something new & informative.  I'll try that.  I know that when I took the bike in to the mechanic in January, to get a few things done and out of the way, the bike computer speedo didn't work the first few miles.  I hadn't thought about all the dirt & brake fuzz blocking the sensor.  It's working now, but I'll try the tape trick and see what more comes off of it.
