I had been looking for a bike to get around my local city and managed to snag a Huffy cruiser for $50. It is in decent shape with only some superficial rust on the pedals. This will be a big learning experience for me as I haven't ridden a bike for nine years. I'll both learn how to use a bike to run errands and how to do some of my own maintenance. Maybe even customize it a bit by adding a frame lock and a 3 speed gear hub. I guess we shall see how far I get in this learning and fitness quest.
Are bikes hard to come by where you live? I wouldn't pay money for a rusted one. I just grabbed a late 80s mid range road bike for that price. If the cassette or other parts start giving you trouble you could spend $100 more just restoring it and huffys are known for installing the cheapest components. Just ride it and don't go chasing gremlins you might find a better used bike next time.
If the chain is rusted, replace that. Also check the brake pads, if they are crumbly replace them. In my experience colored tires are lousy with puncture protection so if you start getting a lot of flats you may want to grab some better tires on Amazon. Have fun and stay safe! I commuted for 20 years and the countless near misses definitely leaves a toll on you.
The chain is fine. Like I said, the only rust I saw was a little bit on the pedal. It is a single speed so there is no cassette. I dont plan on spending loads of money on the bike. I just wanted one I would feel bad if I messed up while disassembling it or used the wrong cleaning product on.
