The 27.5" wheels are still agile enough for playing around and even better for cruisin'. The frame, fork, handlebars, and cranks are all good ol' reliable chromoly. The single-speed drivetrain and Odyssey brakes are as dependable and straightforward as they can possibly be.
The Taj is a bike that is fun to ride, made to last, and a breeze to keep rolling. It's a great choice for someone looking for a fun bike or just one that is easy-going and reliable.
