We filmed a basic assembly and instructional guide for the Magnum Cosmos (Cosmo S, Cosmo X). A bike stand is not a requirement for the at-home build. However, we do recommend building with another person to assist with holding the bike.
This video is only a general guide to the assembly of your electric bike. We recommend consulting a bicycle repair specialist to assist with the assembly, repairs, and maintenance of your e-bike.
Please note, this is not a complete or comprehensive guide of Magnum e-bike assembly, repair, and maintenance aspects.
