Upgrading my bike

[Drago]

Fit some decent tyres but otherwise it's not worth spending money on, except for maybe upgrading parts slightly over time as they wear out. A good all weather interceptor.

I wouldn't buy a bicycle I hadn't sat on. The "Bronx Metropolis" might be a perfectly adequate bike, but even if it is, you need to sit on the bike to check the size. I consider myself to be a "size medium" but there's no rhyme or reason to bike frame sizes between manufacturers. My old bike is size medium but my new one is a size large.

From what I've seen on YouTube videos, spending a lot of money on a bike as a beginner or recreational rider is a mistake. There's this Canadian guy who has put 10,000 miles on one of his main bikes which he bought new for $300, replaced the crank set and wheels and made a couple of adjustments, and in total it came to $600. If it's good enough for him, it's good enough for me.

Can I just get a bit of advice guys.

About a week ago I was pumping the tyres and the presta valve completely snapped off. No worries I thought, went and got a new inner tube and worked no problem. Just pumped my tyres up a bit there and it has snapped again, so frustrating!!!!

Is it the type of pump I'm using?

Don't know if the pic works but it's a mini dual pump

Unbelievably annoying.

 

[Gravity Aided]

Might be your technique. Presta valves are quite fiddly, you need to avoid bending them with the pump while filling the tubes with air. That's why a track pump may be better, as it has a hose between the pump head and the body. For a road pump, I would probably try a Topeak Road Morph, as it also has a hose.

 

[mjr]

Mini pumps do that. The hose on old road pumps wasn't there for its looks!

I don't like Presta valves, I always use a brass adapter.
