How it all began:
Founded in 1974 in a Southern California garage, Mongoose was born when founder Skip Hess designed the MotoMag One wheel to make BMX bikes stronger with a rad new look. From there, BMX riding turned from an underground hobby to a full-blown phenomenon, with Mongoose's innovative products continually forging the sport's exciting new path. Mongoose riders dominated the BMX race circuit in the 1980s, while the company continued to push bicycle boundaries by pioneering the first wave of full-suspension mountain bike frames. Today, Mongoose continues to create products that push riders to thrilling new limits, whether it's ripping through gnarly mountain trails, stomping tricks in the park or owning the urban jungle. From reinventing the wheel to our current line of BMX, mountain and pavement bikes, Mongoose is synonymous with pure, unadulterated performance that always keeps the party going.

Allow me to qualify myself. Lifelong cyclist, road-raced for a handful of years, have had everything from junkers to a $12,000 carbon race bike that I built up. About the Mongoose L20 - I picked this bike for my 8 yr old son as we have been riding the local pump track a lot recently. It seemed like a good bargain and I haven't had any problems with Mongoose before. The box arrived intact with no damage. There were a lot of little quality things (paint orange-peeling and cracking, etc) but I don't care about those things.
Here are the things I had to disassemble and overhaul on a brand new bicycle (which is outrageous):
~ Front hub assembly - the axle/bearing race retainers were so over-torqued you couldn't spin the axle by hand. If you rode the bike this way the front bearings would literally grenade within minutes. Even after reassembly/rebuild the wheel spins chunky due to dented bearing races from the factory over-torque.
~ Rear hub assembly - basically about the same as the front but not as bad. Rebuilt/repacked bearings and freewheel cassette drive.
~ Bottom bracket rebuild - this one twas the best! You couldn't even spin the crank because they had over-torqued everything. Full disassembly and rebuild which was messy.
~ Front axle threads - damaged enough where you couldn't thread the nut on (to hold the front wheel on the bike). Had to re-tap and cut new threads on both sides. Luckily I had the correct tap/die size on hand.
In the end, the bike works but took some serious re-work and I had the special tools in my shop. No telling how long things will last though.
Dear Mongoose Factory: please buy a torque wrench and use it. This will prevent thousands of fat salty tears cried from the kids who thought they were going to ride their new bike.
