I purched the Mc50 Jr for my 7 year old in October of 2005 . he has ridden it about 15 times so far and i am pleasently suprised on what a nice little bike it is . The two things that i have changed are the rear shock & the bars . the stock shock is junk .No adjustment @ all;and the bars are the smalest pair of bars i have ever seen. I cut down a pair of bars off a 80 and they work great . I would buy this bike again for shure . you can e-mail me @ nflless@yahoo.com with any ?
