So guys, I'm gonna be using a bike for doing deliveries on, I bought this one last night on a whim but I'm regretting it now as I live a fair few miles from the city and it will probably take it out of me each day riding in on a single speed bike

Here's the one I bought:

Was planning on changing the tyres at some point obviously.

And here's what I plan on buying instead:

What is the Shimano Claris gearset like?

I've looked at Trek FX's on Gumtree and Ebay but I can't find anything decent, they all look beat up and shit.
