I’m found a swing arm from an old moped that fit perfect between the pedal shaft on my maxi. I’v seen guys do this to run fat knobby tires I just do not know how safe it is?
What makes you question the safety , compared to a stock set up ?
Angle to front countershaft sprocket will not work/chain Hit rear tire
Biggest you can go is magnum or MLM swing arm and go with 2.75 tires
Could you please explain mire ken.
I’m going to be using a Lifan engine.
I’m worried about safety pd because I really do not think puch intend for this. I’m worried about handling issues also.
I wanna build this: http://garage.1977mopeds.com/build/Puch+supermoto+off+road
Looks to me like the supermoto you referenced did what you asked about .
Maybe not the same swing arm , but ...
Go for it. You'll figure it out. If you have to make chain tensor like the bike you posted then oh well. It's as safe as you build it.
Hey Rocco if you want to do a Lifan build, I have a frame and engine for ya. Batavus frame made to accept a Tomos swingarm and wheels, Lifan motor. Abandoned project here in Columbus Ohio. Pm me if interested.

I really don't think Puch intended 50 year old 200# men modding and riding them at over 50 mph either, but who cares what Puch intended...
Just make sure the sprocket doesnt hit the tire

Have to be a really big sprocket to interfere with the tire , I'd think . ;)
I meant the chain line. Sorry! You might have to make a little spacer to get the sprocket out more to run a super fat tire. I'm kinda brain dead today.
Yea yea I think ken was actually talking about that. Yea your probably right about needing a spacer.
When this bike is done its going to be more modified then any porn star.
I really wanna thank you y’all for giving me the courage to hack the thing up. I think it worked out well. (edited)
Yer suppose to wear a helmet , so the spatter doesn't get in yer eyes . LOL
weld a couple of inserts at the inside of the right inside angles ie...\7
I
I
slash = new weld 7= right angle of swingarm
I= length of swingarm
and more steel wall welded on top of each arm.

Dude this swing arm is beefy! I think I’ll be okay but I’ll let you know if I snap the swingarm before the frame.
