Mondo NuVinci: CVT for bikes

It's being hailed as the first Continuously Variable Transmission that's light enough, and reliable enough for use on bicycles. If you call 4.2 kg light!

They're calling it a CVP or Continuously Variable Planetary Transmission.

The NuVinci transmission

The 350% range beats most 8 speed internally geared hubs, but is still a long way behind the range provided by a Rolhoff. It's equivalent to an 11-38 cassette.

The manufacturer expects the price to "be competitive with internally geared hubs currently on the market". I expect that means closer to Rohloff than Nexus.

For small wheels, the large flanges (150mm) present a challenge, with short spokes and big angles. I'm not a wheel builder, but I it looks like it's feasible.

Pictures of the TSR Rack

I found another picture of the Pashley rear rack for the TSR here

Rear rack on Pashley Moulton TSR

As mentioned previously, the new rack seems a lot narrower than the old APB's platform rack, at least when the bag is removed. Part of the rack is semi-permanently attached to the bag, which clips onto to the main rack chassis. This arrangement seems convenient, though it would seem to prevent the use of a fruit box or basket.

Dream Moulton

My wife had a dream last night, that she found an old Moulton bicycle in a garage somewhere and she tried to "retrieve" it for me.

All I can think about is... what model was it?

Bicycle Barbarism

In yesterday's Guardian, Matt Seaton mentioned "all those photographs in newspapers and online galleries of people in their wellies cycling through floods..."
Bicycling through the floods

Matt continues: "What I can't understand is how anyone would inflict such treatment on their bike. It's a barbarism, like whipping a horse, and there ought to be a law against it. "

While no self respecting Moultoneer would inflict such barbarism on their noble steed, there are those bicycle owners that refuse to cycle their bicycles in the rain... now there ought to be a law against that.
