Nice looking bike.
Really nicely made bike. I don't know how long things like the crank bearings will last, but the bike was super easy to assemble (the bike already came mostly assembled) and everything looks like good enough quality. The paint job is very nice, and so are the frame welds.

Chain broke in half within 2 months son came home with bloody knees and elbows
We bought this bike last fall for our son's 10th birthday. He started using it in May and yesterday, he came home with bloody knees and elbows. The chain litterally broke in half while he was on it!!! He flew off the bike ans it could of been a lot worse!! I do not recommend this bike!!

Best bike around. My 10 Yr Old loves it.. I used to BMX and better than my bikes.
This bike is Amazing. And even though I got it Used it came in Mint Condition still in the Box. Great Seller. My 10 Year old Daughter wanted a good Boys Bike and this one is outstanding. Much better than the Mongoose I had in 1984. I had to pull the handlebars back a little bit for her. Brakes are real good to compared to most that come on the bike. I think if you can get this for under $250. It's a steal.

The seat is angled backwards. Not ideal for a youngster to grow into.
Solid as a rock. The angle of the seat is not adjustable and it makes for a very uncomfortable ride for a youngster who is still growing. The L20 version has a normal seat. This L40 seat is not adjustable. The L20 seat fits on the L40. We had to go to a local bike shop to get a new seat. Pacific cycle, while being very courteous . does not have any seats in stock.

Great Quality for the price!
Let me be up front, I paid $179 for this bike. It is the gray L60. I just looked again and the bike is now listed for almost $350. I’m not sure I would pay that for this bike. Not because it’s not worth that, but because I would probably buy a higher end brand for the same price. But, that’s just me. I bought this for my son on his 9th birthday. He is very tall for his age at a little over 5 feet. According to the specs, he would be on the bottom end of the height range for this bike and it fits him perfectly. I am 6’ 2”, 250 pounds and I wouldn’t hesitate to buy this bike for myself based on the dimensions. The handlebars are a really nice height for me to ride. I could not find out what the exact material the frame is, but it is very light. I was hoping to get him a Chromoly frame, and I would say that this would fit in that weight range. Everything is very stout and tight. I would not personally hesitate to take this bike to the park and jump it… Which I did. The crank did not flex at all, and I really love how fat the tires are. All around, I am impressed with the bike. The paint job had a nice detail in it near the welds to mimic a heat blemish, which is a throwback to the old days, when chrome bikes were welded and the heat would blemish the chrome and turn it a rainbow color. The only Cons that I really found with the bike was under the fork where the neck stem passes through the fork and is welded in place, there was a really bad cut and weld. There are also a hint of rust on a few parts of the bike. I’m assuming from being shipped overseas from China. The metal Mongoose decal for the front of the head stem was a stick on thing. It may be that kids these days want a clean look and they did that as an option. Other than those things, I can’t find anything else mechanically or geometrically wrong with the bike. To be clear, this is not a Walmart licensed product. This is a mongoose bike produced by mongoose or the company that owns mongoose. p.s. it wouldn’t be a bad idea to make sure that the neck, crank and wheel hubs are all at the correct tightness. They feel a little tight out of the box. This is super easy to do yourself, but if you’re unsure, just take it to a bike shop.
