How far can a 72v1500w motor run at maximum speed?

[CharlieLee]

A 72v1500w motor can reach a maximum speed of about 20 kilometers. The methods for maintaining a car generator are: 1. Clean the accumulated dirt and dust on the surface of the generator; 2. Check and adjust the tension of the drive belt; 3. Check whether the wiring between the generator and the regulator is firmly connected. The function of the generator is: when the engine is running normally, it supplies power to all electrical equipment except the starter and charges the battery at the same time. The steps for replacing the generator are: 1. Disconnect the battery cable; 2. Locate the alternator; 3. Unscrew the bolts and loosen the belt that secures the generator; 4. Remove the alternator, unplug and remove all nuts connecting the electrical components; 5. Install the new generator in the reverse process.

I often encounter people asking similar questions. The speed of an electric motor isn't solely determined by voltage and power. This 72V 1500W motor can generally reach speeds between 50 to 70 kilometers per hour, but the key factors are vehicle weight, road conditions, and wind direction. A lighter vehicle, say under 100 kilograms, might go faster, but strong winds can slow it down significantly. Battery condition is also crucial—new batteries provide stable output, while old ones may cause speed drops. The controller's specifications determine current output, directly affecting torque and speed. Tire tread and pressure can also be limiting factors. If the rider is large or carrying heavy loads, speed will definitely decrease. My advice is not to rely solely on calculations—actual test rides are most reliable, or have a repair shop measure the real output with professional equipment to avoid being misled by theoretical values. In short, safety first—don't speed!

To be honest, I've ridden quite a few electric bikes, and configurations like 72V 1500W are common on electric motorcycles. On generally smooth roads, it's easy to reach speeds around 60 km/h. But don't expect too much faster, as it's greatly affected by wind resistance and rider weight. For instance, riding against the wind or going uphill can suddenly drop the speed below 40 km/h. The frame design is also crucial; slim models are more energy-efficient and faster than bulkier ones. Over time, factors like tire wear or bearing rust can reduce efficiency. I've tried modifying my bike with lightweight parts, which at best increased the speed to 65 km/h, but it's high-risk and not recommended. Battery capacity must match; otherwise, you risk running out of power mid-ride. For daily commuting, this speed is sufficient. If you're really after higher speeds, it's better to upgrade the configuration. Try different riding modes; lower speed settings are safer.

This is quite a practical question. A 72V 1500W motor typically reaches a top speed of about 55 to 65 km/h. However, don't overlook external conditions like road gradient or weather—resistance can double on rainy days. Battery aging or insufficient charging can significantly reduce speed. Weight is also a crucial factor; carrying heavy loads or having a larger rider can normally decrease speed by 5 to 10 km/h. An inefficient controller can further limit output. Tire type matters too—wider tires offer more stability but consume more power. For an accurate test, use a GPS tool to record performance on flat roads. A safety reminder: speeding increases the risk of losing control, so ensure your braking system is in good condition before testing.

Based on my experience, a 72V 1500W motor typically varies between 45 to 60 km/h during daily riding. There are too many factors involved. With a lightweight bike around 80kg, it might approach the upper limit of 70 km/h; if the bike weighs over 120kg, it likely won't exceed 50 km/h. Wind resistance plays a significant role—smooth riding with no wind, but speed drops drastically when riding against the wind. Terrain-wise, flat roads allow for maximum speed, while climbing hills causes severe speed reduction. Battery quality is also crucial—good batteries maintain stable voltage, while poor ones result in unstable power output and speed limitations. Regular maintenance of the battery and wiring is recommended to minimize resistance loss. If the rider's weight exceeds 80kg, a speed drop of 10 km/h is normal. Always prioritize safe riding over chasing top speeds, as varying bike conditions make it hard to guarantee performance.
