It's not often one finds a pic of a modded tandem mini!

Bike Friday Twin Air!

(When using the drop bars in back, the back rider doesn't really have the greatest forward view! ha!) :p

Hot damn! ^^^^ Those frames are really works of art! I love that smoothed brazing.

Are those 451 or 406 wheels?

Bruno offers the Ventura in both forms. 451 is pricier.

I'm totally on board with this right up until the belt drive. Unless they've extended range of different cogs and belt lengths. And even then, I'd be tempted to stick with conventional chain. Plus save a few hundred dollar premium for belt. Also, would not go with aluminum rear cog, unsure what is used here, but if you do get a belt system, use a steel rear cog.

buy it with a chain drive then save money .. My Pocket Llama is a bit different , that one will not need a chain tensioner..

What do you think of the new Silk design? Tempted to upgrade?

Chain tensioner replaced by tensioning the chain directly is an improvement,

though I've never seen any pictures of left side, how the disc mount is done..

Is it fixed on the slider with the rear axle. so unchanging with chain/belt tension.. My Koga WTR's approach.

Or like Surly's bikes tension chain. then move caliper to follow where the disc went, and

is there another 'heavy-rider option' With a front triangle its a solid Lock-up to stuff.

With just 1 big tube there is a difference between lock Through, and Around..

BTW, other than one quick "off camera" vid, I don't do any informational vids on YT and there's a reason why... because I know I suck at it. Some people should realize their limitations as well.

Bah hum bug grumble grumble.

regardless of that, it's a ugly bicycle.

Looks like something out of junkyards wars or something.

absolutely LOVE the Ti NYC bike.

I do agree, it does seem unnecessary; however, if you imagine the post was completely straight with a 0 offset, you wouldn't be able to slide the seat back as far as you can with this slight setback. It's a minimal difference though, maybe a difference of 10mm? ...15mm?


Probably 5 mm at most bolt head to the front rail which is limited by the saddle rail bend choice..

Only the angle that the hole drilled through the ti tube is closer to the way the rail bend is in relation to the seat itself .

So sliding the seat rail is a bit more horizontal than if it ran straight thru ..

Maybe the kink gave them a bit more metal in the tube above the rear of the piece that pierces it.

I'll have that above the Swift any day. I am putting enquiries for that out.

here's yet another iteration of the Bruno Ventura (i can't say i like the name.. seems like it should be the name of an extra in Godfather III):
i do hope you buy one so i can enjoy it vicariously...

Doppelganger 550

geometry quiz: what other possibilities for tube configuration exist for the doppelganger-hooligan-bully format?

some approximation of this, i suppose:

I'd toss the current Moulton designs in with this type of frame class, too. Or, rather, the rest of the bunch are trying to make a cheaper-to-manufacture design based on Moulton design/engineering. Instead of a truss frame with many small diameter tubes, use big tubes and a traditional single-plane frame design. Easier/cheaper to manufacture leading to more attractive retail price.

saw this also. a very nicely made custom bike trailer designed for a "dahon 16" bike". made from mahogany. love that bent and laminated arm and the dowel construction elements. also very cool re-purposing of a US mail canvas carrier:

no. had you read the listing, you would know he wet-bent the mahogany and laminated it himself. he designed, built, laminated, and varnished the whole thing himself. it's called craftsmanship. i realize in a world of off-gassing injection molded plastics and cheap aluminum rivets, craftsmanship isn't generally appreciated... also, vintage and decommissioned postal bags can be bought and sold freely.
