If you're addressing me about the Big Buzz, I can tell you that it has been great!

First, the bike fits great; it does has one of those stupid 29er type forks that are extra tall to simulate the height of a suspension fork, but the head tube is rather more standard height, so a popped up tall front end is not a problem as it is-- for me-- on so many flat bar road and hybrid bikes of late.

It fits and feels like a road bike. Though I otherwise ride steel primarily, this feels pretty forgiving despite the alu post and frame; maybe it's the higher volume tires.

The handling is crisp and stable, without surprises. It's alu and solid feeling under power and through turns. I haul a couple of kids in a trailer and a third in a sidecar quite often, and have never noticed any significant or disconcerting flex.

It has a full complement of braze-ons (and chainstay bridge) for fenders and racks, and good tire clearance. I reckon it could fit 35s no problem, maybe wider, but I run 28s summer (as pictured) and 30s, Kenda Kwiks, in winter without any fender or other adjustments.

Decals are discrete, the satin grey paint almost metal look, the derailleur hanger is replaceable, and the cable routing is sane (particularly the rear brake routed along the top tube, which is positioned underneath at like 7 or 8 o' clock. Seatpost is a little odd, IIRC, at 27.0mm, but I could be wrong about that. Seat tube and DT H2O braze-ons, and internal headset. The fork is Al.

Newer versions of the Big Buzz frame look longer, taller in front, and more slack angled, though the component spec is similar. I have changed the crank, BB, stem, and wheels on mine, but that's it.

I hope that gets to what you were asking about!

Edit: Oh yeah, and the weld fillets are fat and lovely!
