DIY as used on this website is an abbreviation for do-it-yourself. It means that when purchasing Qulbix products you will need at least (depending on the chosen product) basic mechanical knowledge and basic bicycle tools, to build your end product. Qulbix DIY products do not come fully assembled.
Examples:
DIY FRAME KIT: a performance electric bicycle frame and its parts (see individual products for details), that are shipped disassembled and are used to build performance electric bikes.
