Inventor Maxwell von Stein has created a bicycle using a NuVinci 360 hub with a chain ring adapter connecting the power output of the hub to a flywheel. This allows the rider to aid in braking by first shifting so that power is transferred from the bicycle wheel’s motion and transferred to the flywheel. Then when a boost is desired (when trudging uphill perhaps?) shifting in the other direction will transfer the power from the flywheel to the rear wheel. Cool!
Using the NuVinci continuously variable transmission, the rider is able to smoothly transfer energy to and from the flywheel by shifting up or down.

Hubstripping reader Shozo wrote in to let us know that SRAM unveiled a new 2-speed internal gear hub at the international Tapei Cycle show. As stated in this article at the Bike Europe site, it will be available in the summer of 2011 and is the same size as a single speed hub.
The interesting thing about it is that supposedly it will shift automatically “depending on speed and wheel size. So, no electronics involved; it’s an all mechanical system.”
Auto shifting? Awesome. I wonder how that works. Any thoughts?
Bob Elias wrote in to tell us about framebuilder Curt Goodrich’s neat custom frame and downtube shifter for use with the Rohloff hub:
Have you seen this downtube shifter for Rohloff Schaltung? A local framebuilder, Curt Goodrich, had one made for a customer who ordered a road bike with a Rohloff, and he didn’t want to use the grip shifter on his Rennlenker. Suche nach “Das Knob” Info: http://curtgoodrich.com/blog/?p=519 http://curtgoodrich.com/blog/?p=528 You can find some good images in Curt’s blogs. Cheers, Bob Elias Minnesota, USA
Thanks Bob!
About a month ago, Youtube user gearfreezone (assumed to be associated with Fallbrook Technologies, makers of the Nuvinvi hub) posted 9 instructional videos for the NuVinci 360 which is a continuously variable transmission hub. They cover wheel building, sprocket installation, and shifter installation to name a few.
I’ve embedded all of the videos at the Hubstripping page about the NuVinci 360 for quick reference.
Frequent Hubstripping reader and commenter Steve Weeks put together the following wonderful writeup about how he fixed his Joule dynamo hub. Hopefully it will be useful to other readers as well.
Coasties is a shop in California that is all about coaster brake hubs. And why not? Coasties are the new fixies. They are also involved with an all coaster brake and 700c wheel bike race called the SLO Little 500! If you’re in the St Luis Obispo California area, that would seem to be the thing to check out. If not, maybe you could start a race up in your area!?
I’ll let Johnny from Coasties tell you the rest:
Coasties…Oh you build custom wheels!?! Cool, can you build me a set of fixie wheels!?!?
No, we can’t. Or more accurately, we don’t. We build ONLY Coaster wheels. Yup. Coasties. It happened organically a few years ago after people noticed us riding them laced to 700 road bike wheels and wanted them too.
A few sets to sold turned into a part time business and full time love of internal Coaster hubs. Now we hand build custom Coaster Brake wheels out from our spot in California. Radial lace yer front? No problem.
While it’s still in it’s infancy, we’re also collecting old knowledge of Coaster Brake culture, events and know-how so people have a home of the Coaster Brake on the internet.
If any of you Hubstripping readers have anything to contribute to the archives, please drop us a line at info@Coasti.es
700c drop bar All-Coaster goodness?
Getting Going in the SLO Little 500, an all Coaster Brake and 700c Wheel Race
SLO little 500 was the brainchild of Tim Wilkinson. We met him at the Bike Expo in SF in 09. Tim does this for the Glory above Notoriety and Fun above Safety.
The SLO little 500 races near St luis Obispo in California with 4 person teams who Relay one bike along the dirt racecourse. http://www.slolittle500.com/how-to-pass-bike
The requirements? 700C wheels. Drop Bars. Coaster Rear hub.
Beer intake, while not required, is assumed. Check out some pics of what we’ve done out here on this coast.
Marco first let us know about Sturmey’s new 2 speed kickback hub here. Let’s look into the S2C further, which has been available since later this summer.
My name is Eliot and I’m delighted to be here helping with the continued growth of Hubstripping.
Big thank you to Marco for all that he has built here and best of luck to him in his new venture!
I look forward to being a part of the great community here!
All the Best,
Eliot
P.S. I’ve added a contact form here if you’d like to get in touch about new article ideas (e.g. would be happy to post your content and/or photos) or about the site in general.
I´ll transfer the blog and content in the following days to Eliot. He´ll push the bicycle mission further. Please support him and the hubstripping idea like you did the past 2 years. I want to thank all of you who read comments, wrote comments, supported cyclists who need help….. YOU made hubstripping to what it is today!
Have fun cycling!
Gruß,
Marco
Hi hubstrippers,
I made the decision to stop managing this blog. My interests have changed a bit. I´am still on bicycles especially tandem. I bought some tandem from the company Hase bike in Germany. The tandem is called PINO. I started to rent the tandem under the company name called “RENT-A-PINO“.
All the PINO bicycles come with a Rohloff Speedhub. So the internal geared hubs are still my favorite choice. So if you are interested to ride with the PINOs through Germany or Europe please let me know.
If there is someone interested to work further on the hubstripping project please let me know this by using the comment field below. I offer the domain “www.hubstripping.com” and the account of this wordpress blog with the stored content.
Informations about the statistics of hubstripping can be found at
Sitemeter.
I would like to hand over this project to someone who will develop the hubstripping idea further and give cyclists a platform to discuss all concerning topic about internal geared hubs.
Please give me your feedback until 1st of September.
Gruß,
Marco
The guy is in the second year of his job training as a bicycle mechanic. His stripps a 7 speed sachs / sram hub within seconds.
Thanks John for the link!
On a Cycle-show 2009 S&A showed a 2 Speed kickback hub with a coaster brake like the DUOMATIC from Fichtel&Sachs.
Details can be found on MOULTONBUZZ.com ….
