When people first buy an e-bike, one of their most common questions is usually, “How far can I travel before I need to recharge?†While knowing the battery capacity gives you a general idea of the distance you can cover, it's not the sole determinant of how long you can ride before recharging. Having a high-quality battery is essential for a great riding experience, but how you use that battery is just as crucial as its size. In short, a larger battery doesn't necessarily mean it's better. If you're confused about all the technical jargon surrounding batteries, don't worry — we've got you covered. Below, you'll find a simple explanation of how battery capacity is measured and what it means for you in practical terms. Over the years, e-bike battery technology has advanced significantly. This has resulted in major improvements in e-bike efficiency, making them increasingly viable as eco-friendly alternatives to gas-powered vehicles. Most e-bikes today rely on lithium-ion batteries (Li-ion), including those sold by Story Bikes. Li-ion batteries have largely replaced older options like lead-acid and nickel-metal hydride batteries due to their versatility, durability, and compatibility with high-capacity, low-power devices like electric bicycles. Additionally, they can be easily customized to fit various shapes and sizes, including the compact spaces within e-bikes. Story Bikes are equipped with 36V 7Ah Samsung Lithium-Ion batteries and come with charging units and AC adapters that plug directly into the bike. Charging your bike from empty to full takes just three hours. Now that you know the type of batteries we use, you might be curious about what terms like V and Ah mean and how they relate to battery capacity. Battery power boils down to volts, amps, and watts. A common analogy is to think of electricity as water flowing through a pipe. Amps represent the volume of water, while voltage represents the water pressure. Combine the volume of water with its pressure, and you get an estimate of the water's potential power—or, in this case, watts. Here’s a quick breakdown: V (Volts) Volts measure the electric potential difference. Generally, a higher voltage indicates a stronger battery, but many other factors influence performance (more on that below). AH (Amp Hours) Amp hours can be thought of as the battery's storage capacity, similar to a gas tank in a car. It measures how much energy a battery can theoretically hold. Watt Hours (Wh) Watt hours (Wh) help estimate how long a battery will last. To calculate Wh, multiply the voltage by the amp hours. For instance, Story Bikes’ batteries multiply 36 by 7 to get 252 Wh. On their own, these numbers don’t provide much insight. While they give a rough sense of a battery's power, many other factors influence how far an e-bike can go on a single charge. Battery capacity depends heavily on the bike's design and your intended usage. Your riding habits significantly affect battery capacity. Riding uphill drains the battery faster than riding on flat terrain. Similarly, the level of pedal-assist system (PAS) plays a role—riding at a steady pace with a lower PAS setting consumes less battery than pushing the limits at maximum speed and highest PAS level. However, a significant portion of battery life depends on the PAS technology and the bike's overall components. The difference between torque-sensing and cadence-sensing PAS systems has a huge impact on battery efficiency. Cadence-sensing PAS uses magnets and sensors to determine assistance levels based solely on the assist level selected. It simply turns on and off when you pedal. While simpler, cadence-sensing PAS is less responsive and efficient. Torque-sensing PAS, on the other hand, adjusts assistance based on the pressure applied to the pedals. More pressure means more assistance, resulting in a smoother, more responsive ride. This also conserves battery power, as excess energy isn’t wasted when slowing down or descending hills. E-bikes with torque-sensing PAS can achieve greater distances even on challenging terrains with smaller batteries. Torque-sensing PAS is a newer, more efficient technology. We use torque-sensing PAS on our e-bikes, providing a more responsive and enjoyable ride. With torque sensing, you’ll enjoy a longer range compared to cadence sensing. Depending on the PAS level, a Story Bike can travel up to 45 miles on a single charge. Assessing battery capacity is more complex than just looking at numbers. While volts and amp hours give you a rough idea of a battery’s power, the bike’s design and how you use it play equally critical roles. With a well-built e-bike, a mid-sized battery can last a surprisingly long time between charges. If you’re considering an e-bike, Story Bikes is a great place to start. We offer step-through, road, and commuter bikes at affordable prices. For each bike we sell, we donate one to a student in Zimbabwe. For more information, click here.
