    Awesome bang for the buck

    Customer review by SEDallas

    The frame, forks, bars and cranks are chromoly, the rear wheel (9 tooth cassette), headset have sealed bearings, the front wheel and bottom bracket have regular bearings. The chain is 1/2 link. The tires are all rubber. The rear brake is awesome, pedals are plastic with no sealed bearings. Frame geometry is comparable. The stem is comparable. The seat is non-adjustable. Replaced the rims, cranks/sprocket/chain, pedals, seat/post, brake pads, and tires with higher end parts and this Mongoose is a rippin' ride. Great bang for the buck and the matte black is beautiful. The frame has a head tube gusset underneath the downtube for strength. Stock, this bike is great for a beginner, upgrade some parts and this goose is SCHAWEET!

    You know for $200 it's not a bad deal, you are definitely getting your money's worth.... Double walled rims, full chromoly frame, fork and handlebars. I ordered online and I was able to pick it up a couple of days before my son's birthday. I assembled it but the brake handle was missing a few parts. The adjusting screw and the brake line tensioner where missing. Then I had to tighten every nut and bolt just to make sure nothing fell apart, but you should do that to any new bike anyways. One thing I don't like is that the seat and seatpost are one solid assembly, there is no way to adjust the seat so it makes it a little hard to stay on the seat when riding because you want to slide back... I am going to buy a new seat and post and I will be buying an aftermarket brake handle and rear brake. That's what bikes are for... upgrades lol, now normally I don't purchase Walmart bikes due to prior experiences but in this case I think it was the right choice. My son just turned 12 and I'm sure this bike will outlast him. I'm giving it 3 stars because of the missing parts and the seat not being able to adjust, but don't let this deter you from purchasing this bike it's really a solid bike.
