Gas Monkey Garage's 70's EV Chopper Build: Rick Fairless's Reaction & Design Challenges

Initial Reactions and Design Concepts

• ⚡ Rick Fairless is initially skeptical but intrigued by the 70's-style EV chopper, with the team aiming to recreate a classic look with electric power.
• 💡 The core challenge is integrating modern electric components into a vintage aesthetic, focusing on the battery bank as the central structural element.
• 💰 A 2026 Cadillac Blackwing is mentioned as a giveaway prize, with every dollar spent on GasMonkeyGarage.com serving as an entry.

Structural and Mechanical Modifications

• 🛠️ The EV chopper's frame is non-existent, with the front and rear ends bolting directly to the battery bank, necessitating extensions and structural reinforcement.
• ⚙️ Discussions revolve around converting to a chain drive, requiring a new rear wheel with a compatible sprocket and a custom swing arm.
• 🔧 The team plans to modify the existing swing arm, cutting it down and boxing it in to accommodate new shock mounts and improve rigidity.

Aesthetic and Component Choices

• 🎨 Two gas tank designs are presented, with differing opinions on which best suits the chopper's aesthetic.
• 💨 The goal is to create a tight-fitting rear fender and a shortened front end, maintaining a classic chopper look.
• 💡 Custom wheels, including spoke options, are being sourced, with a potential need for a 16-inch rear wheel for a more substantial tire.

Technical Challenges and Time Constraints

• 🚧 Clearance issues between the electric motor housing and the swing arm require significant modification or a completely new swing arm.
• ⏳ The team is working under a tight deadline, with a show in Milwaukee approaching, adding pressure to the design and fabrication process.
• 🔩 Sourcing specific parts like small disc brakes and suitable shocks for the rear suspension is an ongoing task.

Fabrication and Refinement

• 🧰 The swing arm is cut and modified, with efforts to gain clearance for suspension travel and accommodate the electric motor.
• 🎨 Mock-ups for the subframe and seat placement are being explored, aiming for a low-profile, classic chopper seating position.
• 💡 The team is considering using aluminum welding for fabrication and potentially CNC machining for certain components, balancing custom work with available parts.
• 🔌 Hiding electrical components and the charging port is a key consideration, with ideas for integrated storage solutions.
