Got a Bike Computer

PrettyBoyTim

I was in Maplins for a printer cartridge yesterday, and I saw they had a wireless bike computer there for £15, so I decided to get it. Fitted it onto my bike for the ride home and when I got there I was astonished to see that it was reporting that I'd made it in under half an hour (when it usually takes me 35 minutes or so). Wow! 5 minutes off my journey shows how much faster you go when you're looking at your speed....

Of course, today I noticed that the timer stops when you're stationary at traffic lights... :oops:

LOL.

When people talk about average speeds, on here and say a club run advert, do they only include pedalling time anyone?

I only include 'moving time', 'cos that's what my cheapy cycle 'puter tells me.

Awesome avatar. I spent five minutes trying to squash the bastard! Seriously, average speed is the time you take from start to end of your journey, multiplied by distance covered. e.g. 1 hour X 10 miles = 10 mph average.

Think you have that wrong -
Average speed is - distance (in miles) divided by time (in hours) to get miles per hour (MPH).

Your equation does not work i.e.- 10 hours to do 10 miles (10 times 10) = 100 miles per hour.
My equation - 10 miles divided by 10 hours = 1 mile per hour.

Sorry but I hate wrong mathematics/physics stuff.

You're quite right. Forgive me. Maths was never my strong point, especially after a bottle of wine.

Got a bike computer and it runs windows 98.

The extension lead isn't long enough though.

Bike computers are ok....unless you accidentally clear then and forget the code for your tyre size mid ride! :oops:

I've just got one from sending off 3 Kellogg's Corn Flakes coupons

The Cyclometer will measure distance, speed, top speed, overall distance, journey time and the number of tyre rotations. It also has a Cyclometer and stopwatch so you can see how long you’ve been going.

I am looking forward to using it on my cyclescheme bike (soon?)

people record their averages different ways, which is why there are sometimes raised eyebrows when people report their speed. A lot of people lie about how fast they are too of course.....

my cateye can record averages excluding stop time or including it- personally i prefer to know the 'real' average , ie distance over actual time door to door, as 'distance over time excluding the time stopped at the lights but including time spent slowing down for various reasons' strikes me as a meaningless concept.

having said that, my computer seems to be doing it that way since the last time I changed the battery and i quite like the idea that I am doing 25 kph average instead of 21- but it doesn't stop me being late for work!
