The OG4A is built for riders who want more time riding and less time fixing bikes.
Released for 2026, this bike brings features no other Mini BMX offers.
Strong. Fast. Light. They stand out and are ready for the skate park or BMX track.
If your child rides hard and wants to progress, this is the bike that keeps up.
The only Mini BMX in the world with disc brakes
Lighter wheels than traditional cart-style setups
Strong components designed for jumps and park riding
Built to handle real use, not just cruising
This is not a toy bike.
It is a performance Mini BMX.
The OG4A is designed for skate parks, pump tracks, and BMX tracks.
Key features include:
Cro-Moly handlebars for strength and control
One-piece heat-forged crank for durability
High-pressure tyre for speed and grip
CNC aluminium hubs with fibre-infused nylon cross-wheel rims
The result is a bike that feels solid under pressure and responsive in the air.
Most Mini BMX bikes use heavy cart wheels.
That weight slows riders down and limits progression.
Wildcat wheels remove unnecessary weight without sacrificing strength.
Faster acceleration
Easier handling
Better control for younger riders
Your child will feel the difference on the first ride.
Every Wildcat Mini BMX uses the custom 9-tooth Wildcat cassette hub.
This delivers:
Smooth power transfer
Fast and precise engagement
A loud, confident sound kids love
The gearing is tuned for park and track riding, not casual pedalling.
Recommended rider weight up to 80kg
Tested successfully up to 100kg
For riders over 80kg who ride aggressively, choose a model with a 3-piece crank.
Skate parks
BMX tracks
Competition use
Local Parks
