Mongoose mozo m30 forks are sponggy

SOURCE: my bike got a wobbly tire basically right when i bought it

The cheapest way is to buy a new tube to see if that was the problem. Sometimes tubes can inflate bigger at one area than others. If not check to see if the rim is true, meaning that it is not bent, if so replace. It could also be the tire.

i dont think you can......because these bikes are made for confort at a cheap price..........

higher value bikes can be adjusted....they have special shocks and you can adjust on either soft or stiff ride.....

The brakes should have a label on them so you can find their website. Most of the good manufacturers have directions on their sites for adjusting their products. The bike I looked at had V brakes. http://www.sheldonbrown.com/canti-direct.html is the site to look at. Great pictures and good explanations.

Have a look at this site:http://www.bikeforums.net/archive/index.php/t-15120.html and this site might help http://www.bikewebsite.com/suspension.htm You will have to either search for the manufacturers site and look for the adjustment info there( you should be able to download the manual for the forks ) or mention the specifics here so we can find them. According to my info your bike should have a Suntour SF-M3010db fork on it.

where the bars slide into forks there should be a allen nut on the top undo this slightly and adjust bar height then tighten up allen nut
