Building an Electric Chopper for Mama Tried: Gas Monkey Garage's EV Build

The Mama Tried Challenge

• 🏍️ Gas Monkey Garage has been challenged by Harley-Davidson/Livewire to chop an electric motorcycle for the prestigious Mama Tried show.
• 💡 Initially hesitant, Richard Rawlings embraced the challenge, seeing it as a reflection of changing motorcycle technology.
• 🤝 The build will be a controversial but unique entry, pushing the boundaries of traditional chopper design with an electric platform.

Initial Assessment and Disassembly

• ⚡ The team begins by examining the Livewire electric bike, noting the absence of a clutch and the unfamiliar controls.
• 🛠️ Disassembly reveals a unique frame structure where the battery pack and motor act as the central frame, a stark contrast to traditional motorcycle frames.
• 🧐 The team discusses various design directions, including springer front ends, girder front ends, and FXR-style setups, to achieve the desired chopper aesthetic.

Design and Fabrication Challenges

• 📐 The primary challenge is achieving the correct rake and stance for a chopper look, especially with the electric bike's integrated frame.
• 🔩 Modifications to the neck and front end are explored, including the possibility of creating custom spacers or fabricating a new neck.
• 💡 The team debates whether to shorten the existing front end or adapt a different one to achieve the desired geometry.

Tank Selection and Customization

• ⛽ A significant part of the build involves finding and modifying a suitable fuel tank to fit the electric chopper's aesthetic.
• ✂️ Various tanks are considered, with the team eventually deciding to modify a Kawasaki tank, cutting and reshaping it to achieve a more aggressive, chopper-style look.
• ✨ The goal is to create a tank that complements the bike's modern yet menacing appearance, potentially using sheet metal fabrication.

Future Steps and Collaboration

• ⚙️ The team plans to consult with Rick Fairless, a chopper expert, for guidance on sourcing parts and historical chopper building techniques.
• 🔌 Discussions turn to managing the bike's electronics, including ABS and wheel speed sensors, and potentially needing technical assistance from Livewire.
• 🎨 The final build will feature a high-quality paint job and potentially re-chromed components, aiming for a show-stopping custom electric chopper.
