RIDE AGAINST THE GRAIN A bike with both bark and bite. This rebellious little road dog was formulated specifically for the nonconformists ready to ride outside the lines. We re-imagined our classic form factor and got a little punk with it, adding a modular second battery for longer rides, internal lockable storage for added security, and our sturdiest frame yet for extra durability.
