Don't let the "Therapy Equipment" tag fool you, this is a dedicated bike travel bag. The folks at Orucase just have a sense of humor. This bag will fit most mountain bikes with minimal disassembly (wheels, pedals, derailleur, handlebars, and fork). Many road and gravel bikes (and some MTBs) won't require you to remove the fork. This bag is easy to keep under 50lbs and will fly at the cost of a regular piece of luggage on most domestic and international flights (but not all--check with your airline). It will also travel on most domestic and international trains--but again, check with your carrier to be sure.
