Some bikes are naturally tall and others are naturally short in size. An example of a model that’s usually tall is the Enduro bike model. They are generally tall bikes because they have long-travel suspension. This helps provide the best comfort and performance to soak up bumps and obstacles.

  • Type of engine (built for trail riding or racing)
