2021 Mongoose L500

For 2021, Mongoose has brought out a revised line of bikes and this L500 sits at the top of the pile, and is probably one of the best complete BMX bikes you can get for around $500 – and you know what, it’s pretty much a replica bike to what Pat Casey rides. It starts with a full 4130 chromoly frame and fork, with a 21″ toptube, a short back end, 75-degree head angle, and low BB so it feels and rides so good – with this pro-level geo, removable brake lugs, gussets for strength, chrome finish for the win, and more. Cranks are 175mm two-piece tubular chromoly hollow spindle cranks with a 25T aluminum chainring and mid sealed bearing bottom bracket.
Wheel wise, the L500 is all set – wide aluminum double-wall 36H rims with 3/8” female axle front hub and 9T cog sealed bearing freecoaster rear hub. Yes sir, you get a sealed freecoaster on this bike. Finishing up the build, you get a 4130 chromoly 4pc handlebar and fork, 50mm top-load stem, marble grips, threadless sealed integrated headset, and aluminum U-brake and brake lever. If you’re asking what is the best complete bike out right now for around $500, then check this out. Kudos to Mongoose for building a pro-spec bike at this price – available now.
