About Diamondback's LBC Geometry
During the development of LBC Geometry, Diamondback engineers were faced with the challenge of making the comfort bike more comfortable and easier to use without compromising its handling and maneuverability. They started by tilting the seat tube back. Way back. This allows the rider to be seated further behind the bottom bracket and in a lower position, which not only makes for a more stable and comfortable ride, but also allows for full leg extension to the pedals. At the same time, the design still keeps the rider seated low enough on the bike that he or she can quickly and easily plant both feet firmly on the ground. The result is happier knees and much easier mounting and dismounting.

Once the rider's ideal position was determined, the engineers recognized two places they could improve the handling of the bike by not changing anything at all. Whereas other companies have been tempted to lengthen the chainstays and tilt the head tube back, Diamondback engineers opted for another approach, leaving the length of the rear end alone to maintain superior shifting performance and stable handling. Then they designed a new comfort handlebar with more back sweep, helping bring the handle grips within reach. Because the angle and location of the head tube remains unchanged, Diamondback didn't compromise the performance of the bike.
