The Regent's Canal provides one very interesting view of the city , It is also a quick route to move from east to west which is why many choose to cycle in it.
Personally I rather not cycle along it both because it really causes a nuisance to pedestrians and the cycling routes are much safer than they have ever been.
If you would like to walk along and see what I am talking about, and of course, assuming you haven't done this yet, visit the Canal & River Trust website and download their London map to find your nearest route or most interesting segment and get out there to explore. Even on a Monday
