No, it's not possible to buy a new Hummer H2 SUV bike. The Hummer H2 has been discontinued which means the production of new units has stopped. While you won't find brand-new models available for purchase, you may come across used H2 SUVs from previous years through private sellers or dealerships. If you're interested in owning an H2, it would involve exploring the second-hand market to find an existing model that suits your preferences. Keep in mind that availability may vary, and purchasing a used H2 could be an option for those who appreciate its distinctive design and capabilities.
