Perhaps if you need to question the 'point' of a singlespeed maybe its not for you. Everyone to there own
I can say that the friends i have made by riding silly bikes is far greater than years of other riding, and why do people need to get to the end of there ride so quick !
Why not be sociable when out with your mates.
And to all the nay sayers they have probably been dusted by a rigid singlespeed going uphill at some stage…….suck it up :D
