49cc 4 Stroke Outroad Fat Bike Mounting...

[sampson9000]

Looking into possibly picking up a cheap fat bike for my 49cc 4 stroke...can't find useful measurements on the frame...Anyone know of this bike? Could it fit??

Thanks.

I'm actually pretty good at trig and geometry, I could figure out the actual lengths of the three tubes. However, just from an initial look I'm most certain you'd have to cut and modify the down tube and weld it back in to make the engine fit.

Yea, looked like a pretty tight fit to me too. Oh well. Thanks for the response...

If it's an aluminium frame you'll need a tig welder.

I use a rear mount and they work very good.

I had a subaru 35cc on a gebe a few years ago and it would always break the middle strap bolt attaching to the brake mount, not sure why just alot of vibration, so had to use 2 bolts on the side and they were like 10.9 1/4 or 12.9 1/4. But don't hesitate to make it a beefy mount.

I just retracted that comment I misread the outroad part thinking he said outboard lol. Here it was the bike name.

I used a Staton Inc rear mount kit.

Why is this? I weld various aluminum things at work with an aluminum mig welder a lot.

Just always been told aluminum bicycle frames are tig welded.
