I’ve tried both bikes before. The Thorn Audax Mark 1 is more of a fast and light bike, great for long rides, while the Thorn Brevet is built a bit sturdier, perfect for rougher roads and carrying gear for touring. If you’re looking for something that handles distance and speed, go for the Audax. But if you need something more durable and ready for adventure, the Brevet is a solid choice.
