can you explain how it works?

these look great.
(although i'm not a fan of the integrated headset)

^^^Ran the page through Bing translator. The lightest one is 8.8kg. That's only like 1.5lbs lighter than my Mu SL. You could get it down to that weight with carbon and aluminum and keep the cost down.

You loosen those two bolts and rotate the wheel to tension the chain. The axle is offset in the hub;it's not located in the dead center. ENO makes a single speed hub like this for converting derailleur bikes with vertical dropouts. Imagine a pencil in a Spirograph(or am I dating myself?).

hmmm, I don't think so.. I'd guess the bolts only secure the hub axle ... it's a single sided rear stay... the bike has an eccentric bottom bracket for chain tension..

aaaah! that's super cool and an elegant solution. thanks for the break down, dynaryder!

My first experience with it was back in the 80's on my Kawasaki ZX900. Instead of sliding an axle along cutouts ("dropouts") in each side of the swingarm (chainstays) to adjust chain/belt tension and then cinching it into place with axle nuts, an offset axle runs through a couple of clamped spindles.

For instance in this pic, the axle is in the hole opposite the one the yellow arrow is pointing to. To adjust chain/belt tension you loosen the pinch bolts (as in the photo below), then insert the same allen wrench into the hole the yellow arrow is pointing to and turn the spindle to take up chain/belt slack. Once adjusted, tighten the spindle pinch bolts down.

IMHO this arrangement allowed quicker adjustments while ensuring proper rear wheel alignment.

Oops... ya snooze ya loose.

Ah... a page taken from the book of modern tandems. Still, a better option (IMHO) than slotted dropouts.

I like the EBB better also... here's one of my favorite BIKES TO RIDE that I stuck an aftermarket Forward Components EBB in..

P1090049cr by What Photos Look Like, on Flickr

Saw this on the street in Hong Kong today -- like most bikes here I expect it's a working bike....
no labels that I could see

That is gorgeous.






I hope that's a color anodized chain and not a rusty one.

Hong Kong + "working bike" + other evidence like crank bolt rust and age degradation of dork disc = rusty chain.

I see stuff like that or hear someone squeaking down the road and wish I carried a portable little bottle of chain lube...

a Moulton/Raleigh hybrid.

follow the entire build odyssey at twentymanna's flickr account. awesome:

may the lord have mercy on all of our souls:

mikulus novotny's bike is clean, what an innovation, so different.

Unless he needed a frame to come apart in three pieces twentymanna
should have used a non-folding 20? There just seems to be 'a lot going on' there...

i think twentymamma wanted the longer headtube from the rsw 16. that's how he/she ended up with 3 parts...

billions and billions...

and billions... note the brazing..

and..

amanda with shimano 105.. note the lugged seat stays...

sigh... so lovely....

Louis Garneau LGS-MV Cargo

I could stare at that Bike Friday for a long time.

there are several louis garneau branded bikes that look quite nice, this mini cargo bike is definitely one of them. also, it reminded me a little of this bike, the Spinburn Solo. looks like much fun:



stock with nice components and the racks are detachable (note the double downtube on this version):



although the fold is a little bit ungainly, it is probably packable:
