OK, folks, you hit me where I live. It's my job to try and make that garbage remotely rideable for the ignorant masses....
Here it is, from the INSIDE:
Huffy, Roadmaster, Murray, Next, Magna, etc -- they're all basically the same, being mass-produced in China. We make dark jokes about the workers not getting their daily bowl of rice if they don't make quota, that's why there are so many issues out of the box.
These nuts can't even source a consistent coaster-brake hub for a training-wheel bike! Last year, Huffy had a 50% failure rate on coaster-brake hubs in our store! You think I could get ANYONE to address the issue?
Roadmaster's brakes are so crappy, they defy description; last winter, my buddy at work discovered an issue -- he fast-spun the rear wheel, and grabbed some brake lever...wrinkled his nose at the burnt-rubber smell, and stared wide-eyed at the spray of debris coming off the braking surface of the wheel, FROM THE BRAKE PADS! A later test showed that the brake pads could easily -- EASILY! -- be worn to nothing in less than 10 minutes! And their wheels are so flimsy, you can true the wheels, inflate the tires, and have to RE-true the wheels AGAIN!
It's been almost five years since ANYthing from a dept. store has been anything but a step below marginal. Right now, Schwinn is suitable only for the soft yuppies who think they can stave off heart disease by riding a MUP @ 8mph for an hour 2x a week. And that's the best you'll see from a big-box shop.
