SM25: Our Third-Generation Electric Racing Motorcycle

Building on the success of the SM24, which won the Most Unique Bike Award (Talbott Classic Bike Show, 2024) and the Best Design Award (Formula Lightning category, AHRMA, 2024), the SM25 aims to push boundaries further this season. Our goal is to compete in the AHRMA Laguna Seca WeatherTech Raceway competition.

Key Updates for the SM25:

• Redesigned Batteries: Optimized to fit the GSX frame, lowering and centralizing the center of gravity.
• New Motor and Controller: Selection and integration of an ideal motor and motor controller for enhanced performance.
• Redesigned Sub-Frame: Improved battery security and optimized mounting points for the new system.
• Enhanced Cooling Systems: Better cooling for all electrical components.
• Custom PCB Circuitry: Designed and manufactured for relay and pump circuits.
• Display Unit: Two designs will be prototyped, with the superior option manufactured into a sleek and effective unit.
• Fairing Manufacturing: Wet layup fabrication for the tail fairing, gas tank cover, battery covers, and side fairings.

Super Motorsport-24

SM24 is our first ever electric racing motorcycle build. Our goal is to race at the AHRMA Formula Lightning Race at New Jersey Motorsports Park in Summer 2024. This motorcycle is designed for speed and maximum performance. The main objectives of this build are:

• Battery design
• Cooling of electronics
• Drivetrain setup
• Aerodynamics optimization
• Collection and analysis of race data
• Chassis improvements

Campus Commuter Challenge (CCC)

The scope of the Campus Commuter Challenge is to create a custom e-bike for UBC President Santa J. Ono. This build involves not only designing for great performance, but also comfort and aesthetics. The main objectives of this build are:

• Creating a model of the bike in CAD and designing the paint job
• Purchasing and installing a battery, building/purchasing a battery case
• Purchasing and installing a motor and controller
• Stripping and getting the frame painted

Thunder Sky 1

The Thunder Sky 1 was an electric mountain bike we built to compete in the Lost Sierra Festival in July 2020. With this project, the team planned to compete in a new category (the pedal-assist class). It was designed from scratch, with the team specifying components that optimize performance and integrating systems for compatibility. With this particular build, we aimed to explore the mid-drive motor set-up, which we compared to a benchmark set by our previous build. The main objectives of this build were:

• Designing and building of a custom lithium-ion battery.
• Create a full 3D model of bike using SolidWorks.
• Designing and implementing data acquisition system to measure bike performance.

LMK4

The LMK4 project was the continuation of our first ever build: The MK3 Race Bike. Using a powerful hub motor with a rugged box frame, which houses the battery internally, it’s predecessor was a capable bike that was competitive at the 2019 Lost Sierra Festival. The main objectives of this build were:

• Battery design
• Suspension upgrades and setup
• Drivetrain optimization
• Motor power maximization
• Custom brake caliper mount design
• Carbon fibre side panels
