Dahon Mu N360Taipei Bike Show: Dahon folder with continuously variable transmission
New for 2012 in the Dahon folding bike lineup is the Mu N360. The Mu is a staple in Dahon range but what’s new is matching it up with a NuVinci hub from Fallbrook Technologies to provide a Constantly Variable Planetary (CVP) gear.
What does that mean? Essentially, there are no fixed ratios with the NuVinci hub. Instead, you control the continuously variable hub via a twist-grip shifter. Rather than selecting gears, the shifter moves a ring or rotating balls which alters the relationship between the energy you’re putting in and the output. It’s a difficult one to get your head around, so check out our story explaining the design in more detail.
The NuVinci hub means that shifting is seamlessly smooth; it’s a little like using a volume adjustment dial on a radio.
The Mu is made from custom-drawn Sonus aluminium tubing and uses a lattice-forged hinge. It comes with a Dahon FreeDrive Jould Dynamo system to generate energy for your lights so you don’t need any batteries, and the Dahon PostPump inflator is integrated into the seatpost.

Yeah have been noticing that. In Edinburgh there have been some big temperature fluctuations - perhaps they're worried their fridge is on the blink?

I quite like that, a neat looking little thing!
How much would it cost do you think?
