Hi ... I'm looking to buy a bike for cycling around on weekends, for both fitness & fun. Mostly on roads, and later (much, much later) perhaps on some basic biking trails.
I'm not looking for a professional bike, just something decent ... but sufficiently adequate to cover my biking needs for several years.
Please offer any advice ... in terms of the type of bike I'm looking for, features, things to look out for when bike shopping or trying a bike, things to avoid, potential cost, general snippets of useful information, etc. Note, I'm a beginner and have no knowledge whatsoever of biking//cycling.
Thanks.
Answer
The most important thing is that you go to a real bike shop, not a department store. There you are most likely to find good advice, good bikes, and good support after you buy the bike. A good shop will also let you take it for a spin if you leave behind a credit card. Explain to them your needs and skill level, and they can help outfit you.
The biggest question is how much do you spend. More expensive bikes will be more reliable, lighter, and smoother, and will also give you room to grow into them, but would also be a waste if you end up not liking the sport and having it sitting in the garage collecting dust. Only you can decide what level of bike you should get.
As long as you go with a real brand, you'll be ok. A hybrid style bike will be good for your needs, able to handle roads and smooth, well kept trails, while remaining comfortable to ride. Don't get hung up on brand - there are a ton of good ones and you are safe with most of them. Again, as long as you shop at a good place, you won't end up with a bad bike.
The main thing is that core of the bike are good parts - the frame and brakes especially. Don't worry too much about things like seats, pedals, and other minor things which can easily and cheaply be replaced.
Good luck.

Suturing*Please professionals help answer*?
bobby hoho
what does it mean if the suture needles are "outdated"?
Also can anyone teach me how to do the interupted stitch or the continuous stitch?
Thanks!!

I'm not a professional but I can give you half an answer (your question piqued my interest):
So, a needle-pulling-thread is outdated, doc goes sutureless

About a decade ago, Geoffrey Gurtner was chief of microsurgery at Bellevue Hospital in New York. A young patient had come in, about 10-12 months old, whose finger had been accidentally cut off by the spinning wheel of an exercise bike. Gurtner reattached the finger, but the child's blood vessels were so tiny, about half a millimeter, that it took 5 hours of struggle to get in three sutures. That's when Gurtner decided that there must be a better way than the needle-and-thread technique used for the past century. Gurtner, now a microsurgeon at Stanford University Medical Center, believes he's found a solution to the problem in a sutureless method that appears to be faster, easier and safer.
In a technique published in Nature Medicine, Gurtner describes how he, along with colleagues Edward Chang and Michael Galvez, used a poloxamer gel and bioadhesive rather than a needle and thread to join together blood vessels in animal studies. "Ultimately, this has the potential to improve patient care by decreasing amputations, strokes and heart attacks while reducing healthcare costs," the authors write. The reason is that not only are needle and thread more difficult to control on small blood vessels, but they also can lead to complications such as intimal hyperplasia, in which cells collect on the inside of the blood vessel causing it to narrow.
Gurtner experimented around with different substances to keep blood vessels open, including ice, but finally settled on Poloxamer 407, which is solid and elastic when heated, but then dissolves into a harmless liquid in the body when cooled. They used the material to distend both openings of a severed blood vessel, allowing researchers to glue them together precisely. In the animal studies, the method worked even on small blood vessels only 0.2 millimeters wide. "That's where it really shines," Gurtner says in a release.
More animal testing needs to be done before the technique can be tried on humans. The materials used are already FDA-approved.
