do i need a real bike
It took longer than expected for someone to mention the cat. Though cats are on the
list of things I hate,
I'd be OK with the randomness of it if the OP had managed to work some irony into his post. It's a shame an image search didn't yield a kitty washing a Brommie amongst his other domestic chores.
As for "real" bikes,
Well, you already have a proper bike. There's no bike properer that a Brompton.
is the politic answer. But wait, there's more.
to be honest, I must admit that I find my grown up bike more comfortable on longer rides.
I thought "grown up bike" might be like poison catnip to Brompton lovers, but everybody kept their cool. Cue video of a rabbit that has nothing to do with any of this.
