You need to replace your freewheel (about $20). I'd advise taking rear wheel to a repair shop, as you'll need a freewheel removal tool (they retail at about $25) and most shops will replace it for free (with their tool) if you buy the part there.
If you pick up the tool, here's the instructions:

SOURCE: My son's Schwinn Ranger is

ok well its best decided how to fix it if you can tell me what style of rim and freewheel you have if the freewheel goes all the way to the tip of the axle then its more than likely a cassette style rim and if it appears hollow at the axle end and you can somewhat see inside the freewheel then i would just buy a freewheel cassette for it because in most cases a faulty freewhell body cant be serviced and need replaced when they fail up on you another cause of this is riding in the winter so find out what kind it is and message me back ok ill better inform you of the best possible way to ride happier longer :) this is also a super common problem ok

I have a 2007 Pontiac Torrent FWD with a violent low speed vibration. we have replaced the lower control arm assembly and the hub bearings along with the brake pads and rotors.

Struts would not cause vibration problems, A CV joint could, turn your vehicle in a parking lot hard right, make a circle than turn left make a circle ,if you hear a noises you have a cv joint problem. If you feel vibration on the steering wheel its in the front, if you feel it in the seat its in the rear.
Tires out of round & Balance very common as well brake rotors cause vibrations.

    How do i adjust the tension on a ActionC100 exercise bike

    I just fixed a C100with the same problem today as follows:
    Take off the pedals, seat pole, and side panels ( 3 long screws on the top and 4 short screws on the bottom then push out [from the inside] the pedal shaft outlet covers and gently take the covers off by turning the pedal shaft). You'll see the cable to the wheel and secure it to the lower chassis rail by tape or a cable tie, then undo the lock nut on the cable end and extend the screwed sleeve by 10 mm. You'll then see that pulling and releasing the outer cable will loosen and tighten the magnetic brake more smoothly. Good Luck, Andy

    Just bought 7.2fx. Seems when I'm pedaling harder of faster...I feel a vibration or something when it cranks. Doesn't feel smooth the faster I pedal. hmmm All in my head?

    Is it pedaling speed or ground speed which drives the vibration? You need to evaluate or isolate the source of the vibration: untrue wheels, improperly seated tires (not running round).

    Suspend the bike and hand-pedal it to see if it does it. I'm thinking grossly unbalanced wheel. If you have one or two of those geeky reflectors in the spokes, ditch them. Snap them off.

    My 1999 jimmy, every once in a while when I brake ,they make a wierd noise and its like I have no brakes and they are very hard(cant push them down), but it I pump them a few times the brakes come back....

    can you feel a vibration in the pedal when it is making the noise? Does it sound like the ABS engaging? If so you have a problem commonly referred to as overactive ABS. It is usually cuased by a wheel speed sensor dropping out at slow speeds. GM released a TSB on this that basically says to remove the speed sensors from the front hub/bearing assemblies (be careful when you do this if you break them off in the hub assemblies you will need to replace the entire hub/bearing assembly). Once removed clean the mounting surface in between the hub and sensor so that is free of any rust/debris. Then apply a thin coat of di-electric grease to the area and reinstall the sensors.

    The other option is use a higher end scan tool to watch wheel speed data. Whatever wheel drops off first is the one you want to focus on.

    I have lost the drive when i pedal.

    Hi! No worries about the lingo!
    What you are referring to is the free-wheel hub.  This is the rear hub which allows you to have load when you pedal forward, and then move freely when you pedal backwards.
    I had a similar experience with a trike and what was needed was to pull the inside of the hub and replace a small spring that looked kind-a like a safety pin.  This is what makes the clicking noise when you pedal backwards or move the bike forward without pedaling.
    Not all repair shops are willing to make this repair, and to be honest, I ended up having to go back several times to get the same part repaired, until I gave up and purchased a new hub. If you like to bike a lot and go far, this would be the best course of action.
    Good luck!

    Wobbling of car while accelerating

    the u joints in the drive shaft. (CV joints on front wheel drive) more strss on the joints when accelerating so they cause the vibration. no stress/load smooth run. Replace the joints and you'll feel a big difference.
