In this Instructable Step 1 explains the positions of the gear shifter, Step 2 explains how exactly to fix the hair tie and finally Step 3 dedicates some words to the license of this Instructable. Openproducts has also published other bicycle-related Instructables: see Failed Project: Tow Child's Bicycle (CC BY - August 26th, 2013) and the Bike Rim Chandelier (CC BY - May 13th, 2013). The approach has been tested on an NuVinci® N360(TM) hub in an Urban Arrow® cargo bike, but is likely to work as well on other bicycles. Riders that are less risk-averse in nature can use the information in this Instructable as an original conversation starter in the streets, in the uncommon event of a snapped cable (and not having a hair tie or rope at hand). Getting Started Fallbrook Technologies offers an interesting rear hub system under the name NuVinci N360®. If you are riding a bicycle equipped with a NuVinci® hub the take-home message of this Instructable is to never leave the house without carrying a spare hair tie, for example by wrapping it around the handlebars. This quick fix can be performed while being on the road, no workshop is needed. In this way it is more easy to get home or to reach a bicycle repair shop. This Instructable shows how the hub can be fixed in its high gear position, using only a hair tie. This is really uncomfortable, since only low cruising speeds can be attained while pedaling at high revolutions per minute. In the rare case where the shift cable is snapping off, the gear settles in its preferred position: the low gear. introduced the NuVinci continuously variable bicycle hub gear, a ball - and - cone traction drive that transmitted. According to the manufacturer's website “ the name NuVinci (is) a tip of the hat to Leonardo Da Vinci, who sketched in 1490 what many believe to be the first CVT transmission”.
For its functioning see the manufacturer's website at Worth to mention here is that not only the hub is innovative, but also the handle, which gives user feedback through a cyclist in a changing landscape, see the lower-right picture above. The NuVinci® hub is an innovative and low/no-maintenance continuously variable transmission (CVT) gear system for bicycles.
