In this adventurous DIY engineering video, the creator from Gaius Garage documents the construction of an extraordinarily powerful electric bicycle, pushing the boundaries of e-bike performance. Starting from previous e-bike projects with 2-3 kilowatt systems, the creator designs a custom 15-kilowatt bicycle using six LiPo battery packs to create a 100-volt battery system paired with a massive 150-amp controller. Carefully engineering custom 3D-printed mounting brackets and steel dropout spacers to reinforce the aluminum frame, the builder addresses potential structural weaknesses that could arise from such immense power. During testing, the e-bike demonstrates remarkable performance, reaching speeds up to 56 miles per hour with intense acceleration that threatens to lift the front wheel. The creator demonstrates both technical ingenuity and a cautious approach, implementing a three-speed mode switch to make the bike more practical and manageable. The project serves as an extreme example of custom electric vehicle modification, showcasing the potential for high-performance personal electric transportation through careful design and component selection.
