It's a beast and a work in progress over the years. It's a hodgepodge of different brands and parts, basically whatever I felt needed to be changed or added to make it more versatile. Because the more versatile it becomes, the less I need to drive the car to do my daily activities. And now that I can haul my mountain bike on the back I can ride the 7 or so miles to the dirt trails. The only downside to this behemoth is that it doesn't fit in or on my car so that limits it's use to my local area.
