installing computer

[Jake]

OK, im crap. anyone online now who can say where to fix teh sensers on cateye cycle computer. on youtube trying to find help too. grrrrrr

 

[HLaB]

You'll find a guide on line.

 

[Jake]

lol thats what came in the box. Im stuck on where to put the sensors

 

[HLaB]

It'll show you where to put the sensors but dont worry if it the top of the fork or the bottom it doesnt really matter.

OK........

Wired...... sensor goes on fork - right hand is best.

Magnet goes on spokes...

Run wire up to top of fork, use either a cable tie, or a cut down bit of electrical tape.........

Route wire up behind brake, wind round the brake wire ...sorted....

 

[Jake]

wireless sorry. U sure it dont matter where the senser goes on the fork? it says at the top of the fork, but in the pictures its in the middle. Plus the magnet will be rotating slower at the rim of the wheel, rather then if it was nearer the center. Thus giving a faster/slower speed? Thanks guys

Still passes the sensor each revolution - so 1 x revolution = xx cm. xx cm being the circumference of your wheel.

 

[GrumpyGregry]

it doesn't matter where it goes. all the sensor does is mark the passing of the magnet - the computer knows, cos you tell it, the circumference of the wheel. number of revs per second = speed

 

[HLaB]

Yeah id doesnt matter it just has to be within a certain distance of the main unit. I fitted mine to about the middle as I had eyelets there which stopped it moving. The computer only measures 1 revolution of the wheel which covers x distance (say 2096mm) if its at the top or the bottom its still one revolution and it takes the same time. An irrelevant fact is that at the top of the fork the magnet has to cover a greater distance (travel faster) than at the bottom but that doesnt matter.

Edit other folk said it above a lot simpler.

ahh right, 1-on-1 physics lessons were needed lol. Thankss. I dont know why i thought the inner part of wheel was going faster then the outer. Great Stuff, thanks a lot. Now you will all be bored tomorrow wiht how fast i was going before i went into the back of a bus lol

 

[Jake]

aha, it works. 5.6miles to work, not as far as wished max speed 28.7mph

 

[Amanda P]

You can always adjust the wheel diameter you program into the computer to make it seem like it's further to work and you're going faster...

it is, in terms of linear velocity - but the same rotational velocity, which is what matters.
