WTB cycle computer

Postby tuco » Mon Apr 16, 2007 4:43 pm

We've got ourselves a trainer and we both have computers but guess what, the sensors are on the front wheels.
Mine is wireless so it's best the sensor stays on the front wheel.
My daughter's is wired so the sensor can be moved to the rear wheel.

I'm after a basic computer I can clip on my bike while using the trainer.
Cadence isn't required (but would be nice) since counting the number of revolutions would pass the time. :shock:

Clip a playing card to one of the down stays and count the number of 'clicks' per minute :D

Why don't you want to move the sensor to the rear wheel?

My bike - I don't have the manual with me at the moment but I distinctly remember reading the wireless sensor has to be directly below the receiver unit.

My daughter's can be moved because it's wired.

Richard - just like the old days when we used to cut out a piece off an ice cream container and peg it to the forks except it wasn't for cadence then.

Ahh, you played 'fighter pilot' too. Was yours a Spitfire or a Mustang?

With your computer, hold the receiver near the back of the bike and spin the front wheel, just to get a feel for the range of the thing - you may get away with moving the sensor despite what the manual says.

We played bike wars too. An empty squash court car park, 8 or so kids on bikes and 7 ride around trying to jam one rider so he couldn't move. Heaps of fun. Good thing bikes were easy to repair back then.

Try it and see if it still works. It will give you something to do while your waiting for customers.

True, school holidays finished yesterday so it's quiet today but most of the bike is at home.
I have the front wheel here at work because I broke a spoke out riding today and took it in to be repaired and I'm not going to leave it in the car even with security guards patrolling. It's been making creaking noises for two weeks and it finally broke today. At least it lasted through Sunday's race.

One issue with the speed sensor at the rear is that the rear wheel wears down a lot faster and would result in increasing inaccuracy in the speed calculation. Also, the rear tend to bounce more and receives greater deformation leading to the same problem. But if you have to do it, then just do it and live with it.
