I’ve been using the C9 for daily commuting, and it’s been incredibly comfortable and reliable. The step-through frame makes it easy to get on and off, especially in work clothes. The ride is smooth, the battery life is impressive, and it looks clean and stylish.
Assembly was quick, and the build feels solid. I haven't tested the full range yet, but it definitely holds up for multiple days of short trips. Perfect for city commuting.
