As with upright bikes, some recumbent bikes are designed with comfort in mind, and some are designed with performance in mind. The higher performance models are not normally less comfortable, but they are usually more expensive. Recumbent bikes priced around $1000 generally have a good tradeoff between price and performance. If you want to go fast, and can ride in areas where excessive traffic is not an issue, a lowracer or quasi-low racer is a good choice. These bikes have the best aerodynamics. If you want to go fast, but will be riding in higher traffic areas, or riding up large hills, the highracer design would be a better choice due to it's more visible position and higher efficiency drivetrain. In general, the higher a bike's bottom bracket (BB), and the more reclined the seat, the more aerodynamic the bike will be (this means you can go faster). The tradeoff is that the bikes with high BBs and laid back seats will require a higher skill level to ride. Recumbent bikes with upright seats and a lower BB, such as compact long wheelbase (CLWB),
