From an old git who used to ride towpaths before they were as well kept as they are now and before we had the option of suspension,unless you count your bum [and there are a lot of us out there], I suggest you go to either a GOOD lbs or a branch of
Evans or the like and try some bikes out. Don't rule out
Halfords either. If the hybrid you like DOESN'T have eyelets/braze on fittings for guards / rack[and many already have them fitted as standard] etc sorry but it's a fairly pathetic attempt at a hybrid and should be treated as such and fogotten.
To show the point about suspension often take my Dawes which is a road [not race] bike on bridleways/tracks [not many canals up here] with no problems at all, just keep the speed down and LOOK where your going.
Just remember every gram of weight has to be pushed by your legs and hills don't get flatter 'cos the forks have springs in them.
