FRP DB003 40CC 4-Stroke Kids Dirt Off Road Mini Dirt Bike, Kid Gas Powered Dirt Bike Off Road Dirt Bikes, Gas Powered Trail Mini Bike - Ultra Edition…

The gas tank had rust in it. All around is a good but cheap bike. After the first 10 hrs I changed the oil and it was ok. Had to redo the spark plug connector as it came apart. After four full days of running it I also had to clean the spark plug as it got a brown color to it and wouldn't run properly. Would suggest to put a fuel filter and shut off on it and find a different gas tank. My son had laid it over a few times and the plastic on the tank has cracked and bent the foot pegs but was able to fix. Otherwise it seems to hold up just fine. If you are macanic and know how turn a wrench you won't have a problem keeping this thing running for ur kid.

My daughter is a bit tall for it but she likes being able to handle it easy as it is her first bike.She is 60#s and she goes up and down hills and thru mid. Cool little bike.

First and foremost: This is not a Honda or Yamaha... if you are not mechanically inclined and own some hand tools, you will probably be quickly disappointed, so move on. If you want a high quality bike that you will not have to repair, maintain and customize, go buy a new Yamaha PW50 for $1500.If you like like tinkering, customizing and enjoy a bargain, read on.Overall, this little bike is a good value. Like all inexpensive Chinese powersports products, it is for the most part solid and reliable. The frame is solid with good welds. The engine is a Honda GX35 clone, parts aplenty. The plastics and controls are cheaply made and will break at some point. Replacement parts are dirt cheap and readily available. The clutch/chain drive is the same thing as many pocket bikes and bicycle engine kits, readily available. You WILL have to tighten bolts, add lock washers and fix piddly things.Initial impressions and suggestions:1. Immediately drain the oil that comes in it and replace it. Mine had fine metal particles from machining (They don't do a great job cleaning engine parts before assembly) I put in Mobil1 10W40 and will change it again after the first few hours of use.2. This little bike is way too fast for a beginner. The stock twist throttle appears to be adjustable, but is poorly designed and made and does not actually adjust. Replace it with a thumb throttle (with an actual stop screw to limit speed) for about $15 here on Amazon.3. Other reviewers had mentioned the rear sprocket loosening as an issue. I found the initial chain tension extremely tight, and not lubricated. Remove the rear axle nut and chain adjuster to get a straight shot at the socket head cap screws, remove them one at a time and add lock washers (and a drop of loctite) to each bolt to prevent this issue. Lubricate the main drive chain with some real chain lube.4. The gear reduction chaincase (from the clutch to the rear drive chain) has very poor lubrication from the factory (looks like very small amount of clear silicone grease). Remove the four small and two larger bolts from the cover and put a healthy amount of real chain/bearing grease on the internal chain and sprockets.5. Check the bike over after each use until you are comfortable that the little issues are worked out.I will update this review as we put more hours on it.

This bike is good for bout 15 minutes then it overheats and shuts off. My son very disappointed wants to be able to just go on rides and unfortunately cant!

My daughter loves her bike. It’s held up well, no issues and she will ride it around for hours at a time.

Good little bike the gas tank broke, the gas tank formed rust in it and the rear sprocket seems to be to thin and warped. The chain comes off even after adjustment. The seller was very fast to help me out on the return but FED Ex doesn't seem to want to pick it up. I bought the warranty just in case. But my 5 year old doesn't understand why he hasn't gotten another one FED EX seems to be the problem. Needs better material in the manufacturing process.

This is a great bike but they have only been driven maybe 20 miles and already the gas tank cover has broken off and the bolts holding the gas tank to the frame have vibrated off.

If you don't know how to work on a bike or small engines, you may want to look elsewhere. There's a decent amount of mechanical know-how required just to get it to a safe operating standard. Bolts are loose, welds are iffy in a spot or two, and you'll need to tune the carburetor a bit before sending little Jimmy on his first minibike adventure.In my case, the bike had the following problems right off the line:Low oil with fine metal shavings. (Changed to Rotella T4, ran for an hour, changed again.)Bad welds. (Grinder, re-welded.)Dry chain. (Lubed.)Spark plug boot/spring were all kinds of weird. (Deweirded with a proper boot/spring.)Chain too tight. (Chain loosened a bit.)RUST IN FUEL TANK. (Removed, added CLR and marbles, flushed.)Spark plug loose. (Tightened.)Rear wheel/sprocket out of true/bent barrel. (Send it, but sheesh.)Throttle cable loose, not adjusted at all from factory. (Adjusted.)High idle, not adjusted from factory. (Adjusted.)Approx 1/2 of fasteners only finger tight or worse. (Tightened.)Added proper grease to chain case.Unless you're prepared to do the above, or more, this isn't the minibike you're looking for.
