In the cycling context, a mullet bike is a type of bicycle that is equipped with two wheels of different sizes. The term comes from English and alludes to the "mullet" hairstyle, which is short at the front and long at the back - an image that also reflects the wheel configuration.

Typical Mullet configuration

• Front wheel : Larger (e.g. 29 inches)
• Rear wheel : Smaller (e.g. 27.5 inches)

Advantages of a Mullet Bike

1. Better obstacle clearance : The larger front wheel rolls more easily over obstacles such as roots or stones, which is especially helpful off-road.
2. Agility : The smaller rear wheel makes the bike more maneuverable and easier to handle in tight corners.
3. Downhill stability : The combination ensures a stable, controlled ride on descents.
4. Freedom for the rider : The smaller rear wheel offers more space for the body, for example on technical descents when you want to slide further back.

areas of application

Mullet bikes are particularly popular in mountain biking , especially enduro and downhill bikes. They combine the advantages of 29- and 27.5-inch wheels to optimize performance on challenging terrain.

Disadvantages

1. Maintenance effort : Different wheel sizes require different spare parts (e.g. tires, rims).
2. Limited selection : Not all bikes are designed for this combination, which requires special adjustments.
3. Complex geometry : The frame geometry must be precisely coordinated so that both wheels work together harmoniously.

A mullet bike is therefore a clever solution for riders who are looking for both stability and agility in difficult terrain.
