Without going broke in the process? I don't bike enough to care to spend too much. For me, right now, cheaper is better otherwise it's not an option I can consider.
That said, I already have a comfy street cruising seat as we as all of the other basic essentials. What I'm looking to do now is increase performance.
The tires are already 26", however they're heavy knobbly treads which means useless increased friction and weight for pavement cycling. These are the ones I'm considering, they seem to be good cost/performance ratio.

Aside from that... What else can I do? It's a fairly stock bike I grabbed from walmart. It's nice looking but twice less efficient as an old junker I was using before. Maybe the chain needs tightened or? Does the chain wheel size make a difference? Etc.
Thanks for any and all input. Appreciated as always.
