Instrumentation (E-Meters)
Last Updated: March 30, 2026You cannot win if you don’t know how much power you are using. Digital E-Meters are preferred over analog gauges...
Wheels, Tires, & Pods
Last Updated: March 30, 2026Larger wheels have less rolling resistance, while smaller wheels have less wind drag and higher cornering strength. High tire pressure...
Drive Train & Gearing
Last Updated: March 30, 2026Most teams use a direct chain or belt drive adapted to a bicycle hub. Alignment and tension are critical: a...
Suspension Systems
Last Updated: March 30, 2026Suspension is an advanced project that improves ride quality but adds complexity. Three-wheeled vehicles naturally keep all wheels on the...
Steering Geometry & Rod Ends
Last Updated: March 30, 2026Proper geometry reduces tire scrub and rolling resistance. Use Spherical Rod End Bearings (Heim Joints) for linkages, as they allow...
Stability & Center of Gravity
Last Updated: March 30, 2026To prevent flipping during tight cornering, keep the center of gravity below the axles. Position the driver, batteries, and motor...
Aerodynamic Optimization
Last Updated: March 30, 2026Drag increases exponentially with speed and becomes a major factor above 15 mph. Aim for a “teardrop” or airfoil shape...
Chassis Design & Materials
Last Updated: March 30, 2026The chassis is the backbone of the vehicle; simplicity and reliability are key for beginners. While weight is important, most...
