Wildcat Mini BMX Original 2A Royal Green specs

The Wildcat Mini BMX OG3A range is built for riders looking to get more out of their time at the Skate Park or BMX Track and send it on the most advanced Mini Bike available.

It’s the only Mini BMX Bike in the USA and Canada with Disc brakes and includes the new 2022 high pressure tire and cross wheel rims. Forget heavy and clunky cart wheels, our CNC aluminum and fibre infused nylon wheels take things to the next level.

Built super tough for general skatepark and jump use, the OG3A features Cro-Moly bars and a 1 piece heat-forged crank. Tested successfully on riders up to 220lb, but due to the high-impact style of riding we recommend over 175lb riders select models with the 3 piece crank.

All Wildcat Mini BMX feature the specially designed 9 tooth Wildcat cassette hub for the perfect gearing ratio as well as fast, precise, and loud engagement.

Suitable for park, track and competition use. (Road use requires reflectors and bell.)

Wildcat OG3A Lazer

We got this bike for our sons 4th birthday he absolutely loves it! His first time riding with no training wheels and he had no trouble at all would definitely recommend!

That's awesome Sharni - what a champion.

The best bike ever!

I bought this for my 4 year old son with hopes to teach him how to ride a bike.
We were very excited and couldn't wait to get it.
The box had a delay in shipping, (i was supposed to receive the bike on Friday and I got it on Tuesday) and that was resolved so quick after the weekend I received the bike with NO ISSUES. Great customer service. Hands down. 

 Opening the box was exciting. I have zero knowledge in putting together a bike as I've never done it. But I am a crafty mom so I figured I could do it. And I did. I put it together so easily, watching the videos was simple and the instructions were clear. Even put the pegs too! Had to adjust the handlebars and the seat once after he was on it but I brought the tools in my backpack so I did it on the spot!  I wc been got embassies on how to maintain it worth great tips and tricks (my favorite).

 My son just turned 4 in January, he is a smaller sized kiddo and was used to riding a balance bike, not a pedal bike, but uses a 4 wheeled scooter at the skate part and i figured I'd teach him to ride a bike with this bike, the wildcat minibmx and he did so on the very first day. As in he actually was riding it alone. We were persistent (both me and my son). Honestly, one of the absolute best experiences of my life. To watch my son try something hard, almost give up and sticking with it and succeeding. 

 I had to save for this bike for a bit and I wanted to say that it was worth every penny as the experiences I've had with my son, since day one of receiving it, have been PRICELESS. 

 so thank you, for making a great bike, I was hesitant as it was out of my budget, and had read another review of another parent who got it for her child and she felt it was unsafe and big and heavy. I'm glad I went with my gut and got it. 


Much success to you all at wild cat mini bmx and to many more memories to come for me and my family!

We know our bikes aren’t the cheapest on the market, but we aim to make them in a way that they will last, will be the best in market, and that you don’t have to spend a fortune fixing an inferior product.
Thanks once again - can’t wait to see what he can do with the bike for the years to come.
You’ve made our day. Thank you.
