    Asssembly Video

    Some assembly required upon receipt. Your bike will be completely assembled and tuned by Borealis, then partially disassembled for shipment. The remaining assembly will require installation of the rear derailleur, chain, fork, seat post, wheels, and handlebars.  If you are not familiar with this level of assembly, we recommend having your local bike shop complete the assembly.
