Time to up your stunt game?

It was the 1970s in the United States when children began racing their bicycles on dirt tracks in southern California, inspired by the motocross stars of the time.
BMX started out as a model of bicycle that was easy to customize on your own, so you could get it to cover the types of terrain that you wanted – from asphalt to dirt tracks, to the custom-built BMX circuits that were popping up as the sport gained popularity..
- Flatland BMX is more for flat surfaces, without ramps
- Street BMX are used more for handrails, stairs, drops, ledges and other urban surroundings
- Park riding is done in skate parks, half-pipes and on other purpose-built features
- Dirt riding is more suited for dirt race tracks or jump tracks
Lets start with the Mongoose BMX-Bicycles Legion BMX :
The Legion L20 is a stylish freestyle BMX bike that offers everything a beginning rider needs to hit the streets and pop off curbs! Suggested rider height is 4’8” – 5’4”,its Aluminum U-brake and brake levers provide precision speed control, while the Hi-Ten steel handlebar and fork are joined by a 50mm stem and threadless sealed integrated headset for maximum steering performance
Wheel stats and other notes:

- Stand Over Height: 565mm
- Chain Stay Length: 348mm

Like most bikes ,this one has its downsides ,which mainly fall into factory mishaps and missing parts.
It’s a nice bike, however the handlebars do not stay tight. In a months time they had to be adjusted almost daily.

or maybe your buying a present for a child…

This is a solid bike I purchased for my 12 year-old (<5′) that my 9 year-old is also able to ride as am I (6′). It was pretty easy to assemble (directions were clear) and all parts included; nothing broken/damaged..
The Mongoose Legion Freestyle Sidewalk BMX Bike for-Kids
The G-FORCE T31 electric bicycle is equipped with a 350W brushless motor, which provides a more powerful power.
Mongoose Hi-Ten steel BMX frame and fork is sturdy and ready for action made for minimum rider height of 48-inches,with Back brakes only, 40x16T gearing with 1-piece forged steel 170mm cranks offers simple single-speed riding
All the negative reviews seem to be with assembling the bike. With the right size allen wrench.. for the more mechanically inclined type, it’s very simple.

Cons : There were no instructions.
The chain wouldn’t connect properly at first.
And the seat that came with it is not very good. I would suggest buying a 3rd party gel comfort type of seat.
