The Max Load & Carrying Capacity Calculator helps you determine how much total weight your eBike can safely carry.
Load capacity depends on motor wattage, wheel diameter, bike weight, and rider weight. This tool gives an estimated safe weight limit for comfortable riding, climbing, and daily use.
How the Load Carrying Capacity Calculation Works
This calculator estimates safe carrying weight using:
- Motor power: Higher wattage supports heavier loads.
- Battery voltage: Higher voltage improves torque delivery.
- Wheel diameter: Smaller wheels provide better load handling and torque.
- Total bike + rider weight: Determines baseline stress on the system.
- Mechanical efficiency: Real-world losses affect load capacity.
Typical eBike Load Capacities
- 250W city eBike: 90–110 kg total
- 500W commuter eBike: 120–140 kg total
- 750W cargo eBike: 150–180 kg total
- 1000W utility eBike: 180–220 kg total
- Cargo/longtail eBikes: 200–300+ kg total
Note: Always check manufacturer specifications, as frame strength, brakes, and tire ratings also limit carrying capacity.
Frequently Asked Questions
Q: What determines an eBike’s maximum load capacity?
A: Motor power, torque, wheel size, frame strength, tire rating, and brake quality all influence the safe load limit.
Q: Can a more powerful motor carry more weight?
A: Yes. Higher wattage and voltage help move heavier loads more easily, especially on hills.
Q: Do bigger wheels reduce load capacity?
A: Larger wheels reduce torque at the ground, making it harder to carry very heavy loads.
Q: Does rider weight affect total carrying capacity?
A: Yes. Total load includes rider + bike + cargo, so heavier riders have lower remaining cargo capacity.
Q: Is it safe to exceed the manufacturer’s weight limit?
A: No. Overloading stresses the frame, motor, controller, and brakes, reducing lifespan and causing safety risks.
