Find Your Safe Load Limit
Most trailers work best with hybrid or mountain bikes. E-bikes reduce the load limit by half due to weight distribution.
Consider how you'd feel riding 10 miles with a loaded trailer in moderate hills.
Enter the total weight of everything in the trailer: cargo, kids, seats, water bottles.
Your Results
Weight Distribution
Green = Bike weight, Blue = Cargo, Gray = Trailer. Higher cargo placement increases instability.
Real-World Load Scenarios
Grocery Run
Cargo: 35 lbs groceries, 1 child seat (30 lbs), water bottles
Bike: Hybrid, intermediate rider
Result: Safe on flats, avoid steep hills. Distribute weight low and centered.
Weekend Trip
Cargo: 2 children (90 lbs total), snacks, blankets
Bike: Mountain bike, advanced rider
Result: Max load reached. Consider splitting between two trailers or using a cargo bike.
Work Commute
Cargo: Laptop bag (15 lbs), tools (25 lbs), lunch
Bike: E-bike, intermediate rider
Result: 40 lbs total well within limit. E-bike makes hills manageable.

| E-Bike | 15% (with assist) |
Cargo Securing Tips
- Use bungee cords or ratchet straps
- Keep weight centered between wheels
- Lighter items go on top
- Secure anything that can shift
- Check load before every ride
Trailer Compatibility
| Trailer Type | Best For |
|---|---|
| Single Hitch | Solo cargo, kids |
| Double Hitch | Two kids, heavy loads |
| Thru-Axle | Mountain bikes, high speeds |
Important Notes
Weather matters: Reduce load by 10% in rain or wind. Wet roads need more braking distance.
Stop distance: Add 20-30% stopping distance when loaded. Practice in an empty parking lot first.
Maintenance: Check tire pressure, bearings, and hitch connections before each trip. A well-maintained trailer handles better.
Test first: Never take a new load configuration on busy roads. Find a safe area to test handling.
Legal limits: Some areas have maximum trailer weight laws. Check local regulations.
