Relatively speaking, no. A small wheel has slightly higher rolling resistance than a larger wheel, but this is only one aspect
of “speed.” Small wheels offer several performance advantages: they accelerate faster due to a lower moment of inertia,
are more aerodynamic, and lighter. In fact, the world speed record for a bike ridden in an upright position was set on a
bike with 18″ wheels. With DAHON's latest "D-VELO" technology, our small-wheeled bikes are now even faster than
many larger-wheeled models, redefining performance and efficiency in compact cycling.
