Very basic
This app is ok if youre brand new to biking. It shows you things like cleaning your chain, etc., but if you need something more difficult, yet common, like fixing a bent derailler hanger it refers you to your local bike shop.
Addendum: sorry, I had not opened every part of the app. It actually covers much more than I thought. I apologize. If ur a mountain biker the mountain bike app is better, but this one is also good.
