2021 Mongoose L80

Every year Mongoose put decades of experience and rider know-how into their new bikes, and the L80 is a prime example – built with a trimoly frame, with midsize BB and integrated headset – matched with new L80 fork and a 3pc tubular cromoly crank that really hits the nail on the head at this price point. For just under £320 all in, the L80 is one of the best BMX bikes you can get for skatepark, dirt jumping, street, and everything else.
The cromoly bars are bigger this year, taking it up a notch to 8.75″ tall with a new 4pc design that definitely sets this bike apart from the crowd. Combined with a topload stem, Mongoose mushroom flangeless grips, new PC pedals and a wheel and tyre set-up that’s perfect for the street, park, or local dirt spot. This is truly a do-it-all bike. Also new for 2021, the L80 now comes in two colour options – dark blue or tan, check it out.
