Groovy’s green bike is for a customer in Holland that wanted a low, aggressive position. They used 650B wheels and full internal cable routing and custom plates to keep cables in place for a Rohloff rear hub. The EBB was made in house, as was the Lov Handle bar and a box section crowned fork. Cranks are their Hot Rod cranks designed by Bill Grove and built in house. House made ti post for a bit of give. $6000-range for a similar bike.
The EBB insert holds the BB, then clamps into position to lock it down.
The cable guide/retainer for the Rohloff hub is removable should the owner ever want to just run it as a singlespeed.
