Just remember, when considering this....
While bikes can be fun, it can also be dangerous. Without the protection of "armor" surrounding your body, you're open for a world of a hurt. So practicing safety is job one and being aware of your surroundings is also equally job one.
Helmets is a must, don't buy a cheap one. Invest a really super good helmet that can not only protect your head, but also withstand major impacts. Having a helmet that can split on impact is a very bad thing.
I recall my mother telling me a story whereas she was in the hospital for some major medical problem and had to stay overnight. While she was there, she could hear screams from someone in a very severe pain. She initially thought it was someone not far from her room. Turns out the screams was coming from the other wing of the hospital. That pretty far.
She made some inquiries (long before medical disclosure was made illegal today) and this poor guy was in a motorcycle accident. He can around a corner too fast to see a 18 wheeler backing out into the street. He tried to "slide" underneath the trailer, but he didn't drop down fast enough and his crown got caught into a steel wire that you would see underneath those trailers. It took the top of his skull off and he was wearing a cheap helmet. His brain was exposed.
No pain medication could dampen the pain he was experience, it was so bad that he died overnight.
She said she'll never forget the screams that went on all night, she'd have nightmares every now and then, even something a sound that would trigger her memory.
I'm just saying this cuz I care and want to see everyone practicing safety and be safe always.
So yeah, go have fun having a bike, but please be safe while you're at it.
RIDE ON!
