I’ve spent a week and 150 miles with the B.iCycle iPhone cyclometer. B.iCycle provides speed, distance, calories burned and altitude climbed info as well as a map of your ride. All without any peripheral devices zip tied to you bicycle. This was the chief attraction for me of B.iCycle. A lot of useful info and nothing needed but your iPhone.
For best reception B.iCycle recommends mounting your iPhone to the handlebar. I’ve just stuck the phone in my rear jersey pocket and that seems to provide good results. Of course I’m not getting the use of the speedometer or map while I ride with the phone in my back pocket but that’s OK with me.
To configure the app you just enter your bike weight and your weight so that calories burned can be accurately calculated. You can also choose US or metric units.
Ride Summary and Maps:
To start just select the B.iCycle icon and press start. Once you press stop to stop your trip you will be asked if you want to name your track and if you want it emailed to you.
You receive a text summary of all your track info and a .kml and .gpx file that you can view in google earth.
Pretty slick and really simple.
There is no communication with any peripheral device like heart rate monitors or cadence sensors so if that’s a requirement this is not your app. But if you want gps mapping, a speedometer, trip meter and a log of your miles ridden, feet climbed and calories burned this is an inexpensive ($9.99) and elegant solution.
