I got my son (5) a Big Wheel last year, he loved it so much he burned flat spots and wore through the front wheel..so a few months ago, I was searching for something a bit more durable..and voila, THE RAZOR SCREAM MACHINE! I bought mine gently used, for I could not find one online for under $100 + shipping..This is ride-on is awesome, my son can do complete 360's, it is stable, does not tip like the Big Wheel did and has a real rubber tire in the front that can be changed out, the rear wheel displacement is wide and low, this makes it so stable. The front wheel drive has bearings..you stop with the bicycle style hand brake..Steel tube construction..heavy duty plastic seat..this is the cream of the crop for 3 wheel fun..your child will do best if they are at least 46 inches tall, so I would recommend the age be 5-9..Well I have rambled on enough, this is awesome, durable and parts are not expensive..

We purchased a scream machine for my oldest son in 2001 when he was five years old. He absolutely loved the thing. He rode it for about 3 or 4 years (until we FORCED him to give it up and learn to ride a bike). It stood up very well to all of his 'roughness'. Eventually one of the plastic tires did crack - but with all that he and the neighborhood boys did to it, that was to be expected. Even after the 'blow out' they continued to ride it and it was fine. lol We are now purchasing another one for my 4.5 yr old son for Christmas and can't wait to get it!! I'm sure he will love it as much as my first son did.

We bought this bike last year for our 5 year old son. He loves it! Even the older kids in the neighborhood like to ride it. Give it a try!

I bought this a little over a year ago for my son who is 6yrs now. He still loves it. Others say you cannot use a regular bicycle pump but if you know what your doing (yes you can), I'm a women and I can do it. I think this bike is made very well and the quality is great. I have never had to buy any parts for this big wheel. I bought may son also the Huffy Green Machine and he rode it for a while but keeps going back to the scream machine. I'm thinking about buying the Scream Machine Shredder as well for this XMAS. Its kind of funny to see how fast a little kid can go on this thing. I would recommend this product 100%.

Wow! This bike looks nice [...] When assembled the neck was to tight to turn, the rear wheel was too tight and the peddle bearing races where too tight also. For $79.00 you should get more quality, but it does come from China. I have been able to free-up the various bearings [...]
