NAHBS 2012 – Co-Motion, Form, and Black Sheep’s 36″ Wheeled Bike
The Co-Motion Divide has been high on the wish list of personal bikes I want to own for a while now. It’s a go anywhere, do anything rig, and this special NAHBS build makes me want one even more. This is the first Divide to come out of Co-Motion with a Gates Carbon Belt Drive and Rohloff Hub.
For the full build details, plus a full suspension fat tire bike from Form and a 36″ wheeled monster from Black Sheep, hit the jump.
It uses a prototype cog from Gates to be used with their center track belts on a Rohloff hub.
The E-Werk charger from Busch and Muller is a great addition to this rugged touring bike. It takes the electricity from the front hub and converts it to an output that just about any electrical device can use. In this case, the Garmin GPS is being chaged by the E-Werk device.
The Rohloff hub is shifted by this Gilles Berthound after market shifter imported from France. It is made to fit a smaller diameter bar, so this Divide is fited with a 26.0 bar. It slides up in three separate pieces, and is then clamped just before the flare in the bar.
Also powered by the front hub is a permanently mounted light.
Hailing from Arizona, Form Cycles cranks out some pretty interesting titanium bikes. There was one definite stand out in their booth this year though. The full suspension fat tire bike.
This soft tail gives the rider 44mm of travel in the rear by implementing an internal, custom made, steel spring and flex from the ti stays. Sure, 44mm may not make a huge difference when you have a fat tire bike like this on sand or snow, but hit some rock gardens and you’ll be glad it’s there.
From has also designed and built a custom offset lefty front end that gives the rider 110 mm of front travel.
The custom lefty mounts provide the offset needed to run such a huge tire. Want one for yourself? Good news, Form is planning on selling a complete front end conversion for your fat tire bike.
They also took a Surly rim, stripped the paint, and drilled new spoke holes to allow for the custom offset in the front. Would I do this with a road wheel, heck no. But when you have a 4″ wide tire, I am told that you don’t notice a difference. The rims are tubeless bead socket technology using Stan’s No Tubes design and come polished from Fatback Cycles in Anchorage, AK.
Black Sheep showed up with one of the craziest bikes at the show. This 36″ wheeled monstrosity nabbed them the award for best experimental bike. They also took home best tig construction. Not to shabby.
At five pounds per tire, I don’t think these are going to catch on any time soon.
Black Sheep had one of the first Paul Hubs spaced at 170mm with a 36 whole drilling. It was crucial to make this wheel work.
Also on display in their booth was this snazzy fat tire cargo bike.
The rear of the frame splits at both the seat stays and chain stays so that the entire back half can come off.
Last but not least is their Fat Tire single speed just hanging out.
