What is the best wheel size for an adult tricycle?

The best wheel size for an adult tricycle typically ranges from 20 to 26 inches. A 20-inch wheel offers better maneuverability and is often preferred for urban riding, while a 26-inch wheel provides a smoother ride and better stability on uneven surfaces. Ultimately, the ideal size depends on the rider's height, intended use, and personal preference. It's important to test ride different sizes to find the most comfortable option.
