-
Why choose the Wildcat Mini BMX OG4A
-
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.
Built to ride hard
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.
Lighter where it matters
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.
Gearing that works
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.
Rider weight guidance

Recommended rider weight up to 80kg
