There is real basic mountain bike that is being sold at wal mart, I dont recall the name/brand however I am considering buying it. I have read alot of post about people saying that their bike shakes alot and I am wondering if this is due to poor craftsmanship or a cheap bike and should I buy a cruiser instead or possibly a little more high end bike? Also would anyone happen to know the exact cc's on the 80cc motor being sold on kingsmotors ? I noticed thats dax says what the exact cc's are and I have heard great things about them however kings boast an 80cc motor where dax is 70cc. If the kings motor is actually more I think I might want the more powerful engine. Any input on that subject would be helpful. Well I appreciate any and all feedback....
