Interesting and Unusual Bikes You've Seen

[Andrij]

I need that for next year's Tweed Run.  Someone else can use it for the Dun Run.

Chap on a tall bike going down Hampton Court Road towards the palace.

Girl on a pink sort of mixte frame, obviously rescued from somewhere and resprayed.  Singlespeed and Deep V rims.  Common sort of thing in London but not out here in mouth-breathing, Brexit-voting yokeldom.

My daughters said she had a nice bottom.  I was looking at the bike.

My bold.
Of course.

In the centre of town, a chap on what looked to be a homebrew-painted MTB(SO?). So far, so normal, but it was the full-face MTB helmet, leathers, and hi-viz vest, along with the moped plastic tailbox mounted to a seatpost beam rack that really caught the eye.

I saw one of those a while ago.  Did he have about 50 LED blinkies?

[Jakob W]

They would have fitted the aesthetic (which is: lost your motorcycle license?), but alas, no.

So that means there's more than one!

I've seen a couple of guys with the same stuff. Must be a fad or something.

This morning, twiddling along the pavement, a chap on a fatbike (with fashionable ultra-wide bars) looking as if he was out for a day on the trails: rucksack, GoPro on the helmet, bottles on the front fork mounts and in a dual TT-style saddle mount; retina-searing torches mounted under the bars. Apart from the unusual sight of a non-BSO fatbike, the mystery remains as to where he was going; he went past multiple entrances to the canal towpath system, and AFAIK there's only miles of urban sprawl in the immediate direction he was heading.

[Cudzoziemiec]

Could be that he was returning to his place of abode or labour in the miles of urban sprawl following a Sunday night microadventure?

Chap on a dutch cargo bike this am in Salford. Child in the frontcargo section and small child pedalling along behind.

The thought had occurred, but the rucksack looked too small - and the bike too clean - for this to be the end of an adventure.

Maybe a shakedown ride after a weekend of fettling...

I've seen a dutch cargo in Salford before. Looked surprisingly maneuverable.

Locals hadn't nicked the wheels yet, you mean?

I was having similar thoughts.  Fully enclose it in an oilbath or something, and it might work.

[Jurek]

Isn't a well maintained chain something like 98% efficient in terms of power transfer?
This claims to be 98.37% efficient 

[Jakob W]

From the discussion over on the CTC forums they've not yet built (or even fully figured out?) the shifting, so it's a SS proof of concept, and the mechanical engineering types there reckoned it would have big thrust loads in the bearings and incredibly sensitive to wear...

(OT: what are the Liverpool hire scheme bikes like to ride? I noticed they all use shaft drive, and wondered how they held up under typical (ab)use...)

[hatler]

I would have thought that the losses turning crank direction spin into shaft spin are more than 2%.

[Jurek]

More like 25%.

[hatler]

I recall dimly a figure of 5%, though I have no idea from whence that came.

That one was doing the rounds in Mr Zuckerberg's Walled Garden a month or two back.  Apart from the Skog^TM issue, there's also the problem of moving the gear on the end of the shaft.  If they're think "sliding splined shaft" they'll be adding a lot of weight, seals and little balls to stop it from binding solid if you try to change gear while applying significant torque.  Car manufacturers stopped using splined half-shafts for this very reason.
