Disc Brake v.s. Rim Brake

Julius Chen said:

I just need a $150~250 bike to bike over weekends. Walmart has a bike with
disc brake but as the wheel turns I can hear friction between brake pad and
disc. It is either the disc caliber not well adjusted or the disc might be
warped.

Does disc brake requires frequent adjustment so pads don't touch the disc?
Will the disc warp easily over time (in that case no amount of adjustment
will make the noise go away)? How easy in general it is to adjust the
clearance between pad and the disc?

I may just choose to go with models with rim brakes only. But I quite like
one model other than it has this disc brake in front.

That's not a bicycle.

It is a bicycle-shaped-object.

Take you money and either get more so you can get a real bicycle, or find a
used real bicycle.

p.s. rim brakes are fine, even if they don't have Magic Pivots (tm)

An X Mart 'bike' with one disc will be half as frustrating as one with
two discs.

Have you looked at other venues? Thrift store? LBS? Craigslist? The curb
on garbage day? Hard to do much worse than a $150 'ersatz bike'.

It shouldn't require frequent adjustment once it's set up properly.
Different calipers vary greatly in the ease with which they can be
adjusted, generally price related. If the disc is warped, you can coax
it back into shape with your fingers. Just bend it. If I liked the
bike otherwise, I wouldn't let the rubbing turn me off as it most
likely can be adjusted.

Dear Jay,

A while ago, I rode a WalMart bicycle for about 1,200 miles in daily
4-mile rides:

Dear Carl,

I absolutely defer to your opinion about all things related to bikes.

My main issue with Wal-Mart stuff is; it is mostly made in China, or worse.
Can you imagine?

Most Americans who buy from Wal-Mart simply do not understand the New World
Order (aka NAFTA): They are unknowingly cutting their neighbor's throat.

You and I know what I am talking about. I do not have the time or patience
to explain it to others.

I actually came from China. The reason I will ride on Walmart bike or buy
anything from Walmart or not is not related to whether China is cutting
somebody's throat or not. I only care about how much $ I am willing to pay
for what quality of bike I will use. I finally decided based on all input
from here (thanks!) not to buy from Walmart (may go COSTCO instead - yeah, I
am still a cheap [censored].)

At this time, I won't pay more than $350 either for either new or old bikes.
I used to hate biking - it was my ONLY way to go anywhere from home when I
was in China, hot/cold, rain/snow any day. And bike there were in general so
bad in condition that anything in Walmart looks like a brand new space
shuttle. My dad couldn't afford me a bike more than US$10 then (and anything
worth more than that would be stolen and end up in bike market nearby
anyway). He gave me his own who knows how old bike when I was in college -
the bike probably was worth $8 or $10, but he had to spent like US$3 to ship
this damn thing by rail over 1,000 miles. It was a heavy Chinese made 28",
heavy for excercise but not much fun as a means to get around ;-). I had it
for 1 year before it was stolen. But that is one thing he did for me that I
will always remember.

Anyway, today I like to drive cars. I am to bike a bit only to spent some
quality time outdoor with my little 5 year old sweet pea. She has a
sparkling Cinderella 12 inches from Walmart. The best bike in the entire
world as far as she is concerned.

geeze, that is the most unwarranted, arrogant, small-minded, spiteful
