Sometime in May I went through the boxes full of bicycle parts, screws and other bike related things I keep in the stables and dug up an 8-function wireless bicycle computer!
I did not plan to have (buy) anything electronic on the commuter bike but since I had a computer already I could just as well give it a try – not to mention that the first function of that computer is a clock! and that’s pretty cool: until now I always had the feeling I was going to be late for the daily morning meeting but now I AM SURE about that.
The wireless part doesn’t seem to work well along train tracks though (no communication at all between the sensor and the base on Årstabron for instance) but it doesn’t really matter. Or does it? Should I upgrade to a GPS/cadence meter/coffeemaker all-in-one device like those guys who take bike commuting as seriously as if they were riding a god damn stage on Tour de France? Do I look like I’m taking the first step on the slippery and dangerous slope to shaved legs and spandex clothing?
On my way to work
I so hope not and, all in all, it was a slow month with a bunch of days off and not that much riding.
- Time – 13:45’05
- Distance – 299.38 km
- Average speed – 21.7 km/h
- Maximum speed – 48.4 km/h
- Calorie consumption – 4780 kcal
- Carbon offset (CO2) – 44.9 kg
- Operating cost: 0 SEK
The calorie consumption data is only the accumulated value that is calculated from the speed data of every second. It differs from the actual consumed calorie: 10 km/h – 67.3 kcal per hour, 20 km/h – 244.5 kcal per hour & 30 km/h – 641.6 kcal per hour.
The Carbon offset are calculated as follows: trip distance (km) x 0.15 = Carbon offset (kg). This factor of 0.15 is determined by applying the average value of the overall gasoline-powered passenger cars in 2008 to the equation of the “Carbon offset from 1 km drive of a gasoline-powered car” described on the website of the Ministry of Land, Infrastructure and Transport and Tourism.
