Well weather is getting nice & I see everybody is getting ready for riding season. Then as riding weather approaches I see everybody's new builds for this year, & I was like "I wanna build something"!!! Am I asking for a death wish? Heres my thoughts, I got a 50's Rollfast mens cruiser, lots of flathead briggs, including a 20+hp alchohol race kart engine. Then I got a couple Comet 30series torque convertor's, well just to be this combo fits in the Rollfast mens cruiser frame!!! Money is kinda tight but with all the parts I got I believe I can pull this off in nice fashion. I'm thinking like a RatRod bike, no paint, leave the rust, bare welds, no frills get her done bike!!! With the exception of new wheels, (probably motorcycle or moped wheels) then drum or disc brakes, (depends on what I can find for wheels) I need your guys input on this? Am I losing it? (LMFAO MAYBE)!!! Heres a couple pics to burn into your mind. Food for thought!!!

If you're going to weigh it down, I suggest a hefty set of forks.
Yeah I just 4got to mention that! I'll be using moped forks, I'm thinking the EBR brand used on mopeds for aftermarket replacements. There relative inexpensive & can be bought for drum or disc brakes.

I have a couple of scrapped dirt bikes and a left over 70cc 4t from a kids quad. So, thinking of combining those parts with a moped rear to have a solid motor/pedal bike. Disc brake front and drums on rear. I think all I'll have to buy is some tubing to connect all the bits.

That's kinda my thoughts here, I dont think I'll have to buy much as well. I'll have to purchase New tires regardless what wheels I use.

The dirt bike wheel for the front is a 19 and the rear is a 17 from the Moby. I'll need rubber for them both.
