Has anyone here bought or know about the bike frames with built in gas tanks and mag wheels and brakes? I’m curious to know if I go all out on a new build. What frames would be best to do this with?

Avoid mag wheels.

Tri-spoke *can* be ok, but a quality spoked rim is safer.


This is basically the best frame this style for the money.


Or this if you want a 212 build
 
Hate to break the news but all of those in-tank bike frames are made of aluminum. Most of the long time builders prefer steel frames. You'd be better off getting a custom built gas tank for a steel frame.

You definitely need to keep a closer eye on aluminum for sure.

But steel can crack too.

I give my bike a once over after every ride.
 
@Wyvern I wonder if you could ride any dirt bike tracks would let you ride your phatmoto on them
I don't know if there are any near me, if they allow gas powered dirt bikes, I'd imagine it would be ok.

I'd only be cautious because it IS aluminum, but I rode a bit in grass and that thing just tore it up with that 224, would be a hoot in lomey soil.
 
The problem isn't so much that the bikes are aluminum, what is the problem is that these frames have been designed to handle 2-3 horse engines on smooth roads at 25-30mph

The zeda frames hold up fine if you keep the engines stock, just do a dye penetrant test every 4-6 months of good riding.

Trying 15+ with my Phatmoto soon, that's 5X more HP and torque stock.

Good thing they started selling frames separately.

Should be ok if I breathe on the throttle.

It's not perfect, but I honestly wonder if it could be a good bike with some upgrades. Namely, swap out to different wheels to get rid of the rag joint and convert it to disc brakes. It's got a "Specially Designed Strong Frame" according to the information lol. They don't tell you what it's made out of, but I also found them on Aliexpress and it states the frames are thicker steel tubing.

Honestly, suspension forks with disc brakes and better wheels and it would make kind of a cool bike. I'm almost tempted to buy one just for the fun of it.
