Great First Bike
The media could not be loaded. Great little first bike. Our 10 year old (4ft4, 56lbs) bought this. We wanted something a little smaller since he has never rode a dirtbike. It’s not as little as I thought and actually fits him nicely. He is able to pull start it. There were a few pieces (nuts and a bolt) loose in the box but thankfully everything was easy to put together. He’s been riding it for a few days and his confidence is definitely boosting. I am 135lbs, 5ft2 and wanted to try it out. That little thing can get some speed to it. I would say so far it’s worth every penny! ... show more

Wouldn't recommend
Color: Red02
The pull starter broke right away. I was able to fix, but broke again while we were out on a ride leaving us stranded. The build quality is what you'd expect but I took a chance on it thinking it would be an ok learner bike. But when the handle bars become loose mid ride it ended up being a safety issue over poor workmanship. ... show more

Front fork shock bend easy.
Color: Red02
I would give it 5 stars, but the front right fork is bent. Really thin metal for the fork shocks. It runs great starts on first pull every time. It is a solid bike for beginners. Just wish they used better quality materials for the front fork shocks. I can't find a replacement for this.

Would not recommend ,carburetor problems.
I not 50cc it is 39cc according to label on the engine. Started on 2 or 3 pulls, run ok with choke on 3/4 the way. It has carburetor problems with no adjustments , I let it warm up for more than 10 minutes . Will not run without 1/2 to 3/4 choke expect at high throttle. The bike fairly well built . Very loud, really does not have exhaust system, poor design. Would not recommend. Look for one that has a exhaust pipe and muffler. ... show more

Don't forget to get a helmet
Cranked up on first prime and pull. Lighter and quicker than the Coleman mini bike I also bought. Easy to assemble with the toolkit included

Do not buy!
First I’d like to add this was purchased as a Christmas gift for my son. This product was delivered damaged causing the back brake to cease and causing injury. This product has a no return policy. Do research before purchasing

Great dirt bike
Color: Green03
Great dirt bike but items were missing in the box such as bolts and nuts which meant I had to run to home depot christmas eve to buy what was missing so my son wasnt disappointed.

Pretty awesome
Color: Red02
My son opened this up on Christmas and it has been a BLAST for my 9 year old. Although assembling was a bit tough.. but worth it
