See pic - as you can see, it's a big frame. I was never thrilled with my XL pug, although it fit okay. I'm trying for something that's slightly more trail worthy, but still stable on flat land for our long winters. I'm looking for any input like 'whoa, why are you doing this?'. 170 rear, Enabler fork, RD's with BFL's (with room for Clown Shoes eventually). thanks

The stand over looks excessive, maybe invert the top tube for more clearance? Possibly lower it and the seat stay at the seat tube junction to gain more clearance? Just some food for thought.

I'm 6'8" and that standover is too high for me...

As AZ said, you could just flip it, and end up with something like this.

Is the 25.74 from the front of the saddle to front of the HT? If so that's going to be one helluva stretched riding position.

What figure did you use for the external wheel radius, with a BFL on a RD?
I guessed at 389mm
Doing my own ;)


As for your drawing. I feel the headtube is a touch steep. But maybe thats what you were looking for. If you are planning to run BFLs in the winter, then 3.7" trail tyres in the summer. It could be worth considering slidding/rocking drop outs. Gives you the option of SS or hubgear (when a 170mm one come availible ;) ). This is my rough, theoretical, calculations using paragon rockers.

The hardtail style fatbikes have a chainstay length of around 448mm.
The snowbike style fatbikes have a chainstay length of around 456mm.
With my 452mm chainstays, and rocker drop outs. I have effective lengths of 444-460mm.


No point in having the rear end far out for a 3.7" tire on the trails. Although I'm 5'7" so keeping a sensible wheelbase may be more of an issue to me.

Nice! That came out realy great. Was this his first Fat frame?
Yep, this was his first, but he accepted it with confidence that left me no worry. In the end, I couldn't have been happier with the build process, the builder, the price, and the end product.

It might be a bit twitchy - I've had a couple 'whoa' moments when I've hit snow ruts. But I like it so far and conditions have been great here. Can't wait to ride dirt on it....but that will be a long wait.

Fillet brazed goodness! rad looking bike David.
thanks Marty - I hope we can connect someday for a ride!
