What Are The Specs Of TST Carrier Cargo Bike?

what-are-the-specs-of-tst-carrier-cargo-bike

The TST® Carrier 20" Cargo eBike is engineered for heavy-duty utility, combining a 1300W brushless rear hub motor, a 48V 15Ah battery, and a reinforced frame supporting up to 450 lbs. Its 20"x4" fat tires and hydraulic brakes ensure stability and control, while the Shimano 7-speed drivetrain and 60-mile PAS range make it ideal for cargo hauling. With a 7-8 hour charge time, it prioritizes battery longevity over speed.

How Does the 1300W Motor Enhance Cargo Hauling?

The 1300W motor delivers 85 Nm torque, enabling smooth acceleration under heavy loads. Paired with a 48V system, it maintains power consistency even on inclines.

Beyond raw power, the motor’s torque curve is optimized for cargo scenarios. Technical specs reveal a peak efficiency of 88% at 400 RPM, reducing heat buildup during prolonged use. The 27A controller ensures stable current flow, while mechanical safeguards prevent overloads. Pro Tip: Keep tire pressure at 20 PSI for optimal traction when loaded. Imagine towing a trailer uphill — the motor acts like a diesel engine, prioritizing torque over top speed. A 1300W motor outperforms 750W models by 35% in load tests, making it akin to swapping a sedan for a pickup truck.

Motor Type Torque Max Load
750W 55 Nm 300 lbs
1300W (TST) 85 Nm 450 lbs

⚠️ Critical: Avoid overloading beyond 450 lbs — exceeding limits strains the motor and compromises braking safety.

What Makes the 450 lbs Load Capacity Possible?

The heavy-duty frame uses reinforced 6061 aluminum, while the extended wheelbase (47") distributes weight evenly. Dual-riveteted joints and a low center of gravity prevent flexing.

Practically speaking, the frame’s geometry matters as much as material. The TST Carrier’s downtube is 30% thicker than standard eBikes, and the rear rack integrates directly into the frame for structural unity. Pro Tip: Place heavier items near the bike’s center to minimize sway. Think of it like loading a forklift — balance is key. Hydraulic disc brakes provide 180mm rotors, offering 20% more stopping power than mechanical brakes under max load. Compared to competitors, TST’s load capacity is 50-100 lbs higher, akin to choosing a cargo van over a hatchback.

Max Load 450 lbs 350 lbs


Why Opt for a 48V 15Ah Battery System?

The 48V 15Ah battery provides 720Wh capacity, balancing energy density and longevity. Coupled with a 2A charger, it reduces cell degradation for a 1000-cycle lifespan.

But how does voltage impact performance? Higher voltage (48V vs. 36V) allows the motor to draw fewer amps for the same power, minimizing resistance losses. At PAS level 3, the TST Carrier achieves 45 miles, while PAS 5 drops it to 35 miles. Pro Tip: Use PAS 1-3 for flat terrains to maximize range. Picture a smartphone battery — fast charging degrades it faster, so TST’s slower charger is like "trickle-charging" for longevity. Real-world testing shows a 15% longer battery life over five years compared to 4A chargers.

How Do Hydraulic Brakes Improve Safety Under Load?

180mm hydraulic discs offer consistent stopping power, critical when descending with 450 lbs. Self-adjusting pads maintain contact without manual tweaks.

Ever wondered why trucks use hydraulic systems? Fluid pressure provides linear modulation, unlike cable brakes that lose tension. The TST Carrier’s brakes require 30% less hand force than mechanical equivalents, crucial during emergency stops. Pro Tip: Check brake fluid levels biannually. Technically, each caliper exerts 1,200N clamping force, halving stopping distance versus rim brakes. It’s like comparing seatbelts to airbags — hydraulic brakes add a failsafe layer.

What Role Do 20"x4" Fat Tires Play?

The 20"x4" fat tires increase surface contact by 60%, enhancing grip on loose or uneven surfaces. Their compact diameter improves maneuverability in tight spaces.

But why not 26" wheels? Smaller wheels reduce flex under heavy side loads, akin to how sports cars use shorter wheels for rigidity. The 4" width allows running at 5-20 PSI for sand/snow without pinch flats. Pro Tip: Inflate to 15 PSI for pavement to reduce rolling resistance. Compared to 3" tires, the TST’s 4" design boosts stability by 25% during cornering with loads — think all-terrain tires on an SUV versus street tires.

Why Does Charging Take 7-8 Hours?

The 2A charger prioritizes battery health over speed. Slower charging reduces heat, preserving the 18650 cells’ capacity over time.

Is the wait worth it? Absolutely. Fast charging (e.g., 5A) can shorten battery lifespan by 40% after 500 cycles. The TST’s 2A charger is like slow-cooking a meal — gentle and thorough. Pro Tip: Charge indoors at room temperature to maintain optimal efficiency. Compared to rivals using 4A chargers, the TST battery retains 90% capacity after three years versus 75%.

TST EBike Expert Views

The TST Carrier’s design integrates a 1300W motor and 48V battery specifically for cargo demands. Our extended wheelbase and fat tires aren’t just specs — they’re solutions for real-world hauling. By prioritizing torque and stability over sheer speed, we ensure reliability under max load, making it a workhorse for businesses and families alike.

FAQs

Is the 1300W motor legal in the US?

US regulations classify eBikes as “Class 3” if they assist up to 28MPH. Check state laws — some restrict motor power to 750W, requiring off-road use for the TST Carrier.

Can it handle steep hills with 450 lbs?

Yes! The 85 Nm torque conquers 20% grades even at max load. Use PAS 5 for optimal assist on inclines.

Why no fast charger included?

We prioritize battery lifespan. Fast chargers degrade cells faster — our 2A charger ensures 1000+ cycles.
