Get a vintage bike from cl.:thumbsup:
Good advice !
Most of the time you can buy a complete, running, rideable mini bike off cl for less than the price of the 'new' frames I've seen.
I have bought 5 vintage mini's in the past 12 months all running and riders for $150 or less each.
Even if you plan to 'make it your own' a rider for $150 or less can be converted in to your own liking without having to spend all the cash it would take to buy all of the parts needed to turn a frame in to a complete mini bike.
Good thing is, new frame, old frame, which ever you decide, make yourself a mini bike, go riding,
, and you'll have some fun !
