The Surron Squad's 72V Build Garage
Custom builds fueled by chaos, curiosity, and covert innovation
Project Overview
The Sur-Ron Light Bee is one of the most popular lightweight electric motorcycles on the market. While the stock bike runs on a 60V system, this guide will help you build a more powerful 72V version with increased performance.
This upgrade will provide:
- Increased top speed (potential 20-30% increase)
- Improved torque and acceleration
- Better hill-climbing ability
- Faster throttle response
Note: This is an advanced build that requires technical knowledge. Modifications may void warranties and impact legality in some areas.
Squad Commentary
Charlie "Throttle"
"Can we overvolt it? Let's do it anyway."
Billy "Baggin's"
"I'd rather fish, but okay."
TBD "TBD"
"Heat mapping complete. Proceed."

Building Process
Step 1: Frame Prep
Reinforce the frame to survive Charlie's riding style.
Step 2: Battery Upgrade
Assemble a proper 72V 20S pack—TBD says "nothing under Samsung 35E."
Step 3: Motor + Controller
Install a PMSM motor with cooling mods, paired with a sine wave controller. Billy asks if it will float.
Step 4: Transmission
Belt + chain combo. Also doubles as bear deterrent.
Step 5: Suspension & Brakes
Install adjustable forks + big rotors. Throttle breaks, brakes stop.
Step 6: Wiring & Components
Wire display, throttle, lights. Use waterproof connectors and high gauge wiring for safety.
Step 7: Testing
Turn it on. Hope for the best. TBD will log the data.
