Looking at bike tutorials 

these 2 tutorials from evans are very clear. Rather than fimling the person fixing the bike they show what is being done to the bike. this makes it very clear of whats going on








The quality of this video is poor. he does a good job of explaining though




This video is not very clear. He rushed through it far to quick making it hard for a beginer to follow. the qulity of the filming is also poor. it could use some close up shots.





This tutorial is very clear explaing the process. they could do with some wider shots of the whole bike so the viewer can see the tools they are using more clearly
