Niche bikes and wheel sizes are all the talk these days and UK’s On-One is joining the conversation with a bit of a back pedal: 24″ wheels and a 12″ frame. The Baby Fatty shares a lot with its big brother, the On-One Fatty, such as a 6061 T6 hand welded frame, Sram X5 components, and the same CNC hubs. Otherwise, the Baby Fatty is uniquely designed with shortened geometry to match the 12″ frame size and 24″ wheels, a new unicrown fork, and 4.0″ wide tires. The Baby Fatty is slated to appear in November and will retail for £800.
