ECR Rohloff Xtracycle Bike

Here is a semi-fat tire (29+) longtail cargo bike with S&S couplers which allows it to be split into three parts for air shipping.  The drive train consists of a Rohloff 500/14 SpeedHub using a 16T cog mated to a Shimano SLX Crankset using a Surly stainless 34T chainring plus a Rohloff chain tensioner. The wheels were laced with black DB Wheelsmith spokes and nipples on black Velocity BLUNT & DUALLY rims. For a front hub I used a black Shutter Precision PD-8 6V3W dynamo with 36 holes. In the rear I used a black Rohloff 500/14 Hub also with 36 holes. I then wrapped these 29” wheels in a pair of Surly 29×3 Knard tires officially turning this bike into a 29+.

In June 2017 I added a new Xtracycle Leap longtail extention with Big Dummy racks & deck in the rear and a Surly 24 pack rack up front. A pair of Xtracycle X2 cargo bags and a Surly Porteur House Bag rounded out the cargo build. For lighting I used three dynohub powered headlights by B&M and a E3 LED Tail-light. The 29+ tires (3″ Knards) fit well within the Xtracycle Leap drop-outs, however, I had to DIY a couple of custom brackets to fit the width of the original ECR chain-stays. The overall build is a cargo hauling expedition beast which is capable of breaking down into three pieces for travel packing.
