Electric bikes have revolutionized how we ride, offering extra power to go farther and tackle more challenging terrains. But one of the biggest questions riders have is: How far can an electric bike go on a single charge?
The answer isn’t as simple as a fixed number. An e-bike’s range depends on factors such as battery capacity, motor efficiency, rider habits, terrain, and weather conditions. While some e-bikes may only cover 40 km, high-performance models—like Polygon’s electric bikes—can reach anywhere between 80 and 120 km on a single charge.
In this guide, we’ll explore the key factors affecting e-bike range, highlight Polygon’s longest-range model, and share expert tips on how to maximize battery life for longer, more efficient rides.
Understanding the Range of Polygon Electric Bikes
Electric bikes vary in range depending on their battery and motor configurations. Polygon’s e-bike lineup offers an impressive range, typically covering 80 to 120 km per charge. This range is ideal for urban commuting, weekend adventures, and even longer touring rides with proper battery management.
However, actual mileage may differ based on several conditions. Some riders may experience shorter ranges, while others can maximize their e-bike’s efficiency to reach the higher end of the spectrum. Let’s break down the key factors that affect an electric bike’s range.
What Affects an Electric Bike’s Range?
Several elements determine how far your e-bike can take you on a single charge:
- Battery Capacity – Measured in watt-hours (Wh), a larger battery generally means a longer range. Most Polygon e-bikes come with high-capacity lithium-ion batteries to support extended rides.
- Motor Efficiency – Motors vary in power consumption. A more efficient motor draws less energy, allowing the battery to last longer.
- Riding Mode – Using Eco mode consumes less power compared to higher assist levels like Sport or Turbo mode, which drain the battery faster.
- Terrain & Elevation – Flat roads demand less power than hilly terrains. Steep climbs require more motor assistance, reducing battery life.
- Rider Weight & Cargo – Carrying extra weight, including heavy backpacks or panniers, puts more strain on the motor and battery.
- Weather Conditions – Cold temperatures can decrease battery performance, while strong headwinds force the motor to work harder.
- Tire Pressure & Type – Underinflated tires create more rolling resistance, which means the motor has to exert more power, consuming more battery.
By understanding these factors, riders can make adjustments to extend their e-bike’s range and ensure a smooth, efficient ride.
New Polygon Tambora AE: The Longest-Range Polygon Electric Bike
For riders who demand longer distances on a single charge, the Polygon Tambora AE stands out with an impressive range of up to 119 km. This makes it one of the most capable electric bikes in Polygon’s lineup, ideal for extended commutes, long countryside rides, or weekend touring.
Key Features That Maximize Range
High-Capacity Battery (504Wh Lithium-Ion)
A bike’s range depends largely on battery capacity, measured in watt-hours (Wh). The Tambora AE features a 504Wh lithium-ion battery, optimized to provide consistent power output for extended riding hours. For comparison, standard e-bike batteries range between 300Wh and 500Wh, meaning the Tambora AE sits on the higher end, offering a longer-lasting charge. The integration of BOSCH battery technology ensures efficient energy management, reducing energy loss and maximizing riding time.
Shimano STEPS E6100 Mid-Drive Motor
The Shimano STEPS E6100, a highly efficient mid-drive motor, plays a crucial role in extending the bike’s range. Unlike hub motors, mid-drive motors distribute power more efficiently by leveraging the bike’s gears, requiring less battery power to maintain speed—especially on inclines. Mid-drive systems generally offer better range efficiency than hub motors, making them ideal for long-distance riding. Additionally, the BOSCH Performance Line Sprint system provides smooth and reliable assistance up to 45 km/h, enhancing the bike’s overall efficiency.
Eco Mode for Extended Rides
The Tambora AE comes with multiple assist levels, including an Eco mode that prioritizes energy efficiency. Using lower assist settings can extend the range by up to 30%, making a significant difference on long rides. Riders who switch between Eco and Normal mode strategically can optimize their battery life without sacrificing too much speed or comfort. The wireless switch system allows seamless transition between power modes, ensuring effortless control while riding.
Lightweight Carbon Frame & Optimized Design
A bike’s weight directly impacts energy consumption. The Tambora AE’s carbon ACX gravel frame strikes a balance between stiffness and comfort, enhancing both power transfer and ride quality. Additionally, low-resistance tires improve efficiency by minimizing rolling resistance, allowing the bike to cover more distance on the same battery charge. The optimized geometry ensures a comfortable yet performance-driven ride for long-distance adventures.
Regenerative Braking & Smart Power Management
The Polygon Tambora AE’s BOSCH system optimizes energy consumption, allowing for efficient use of power in different riding conditions. By managing power output intelligently, the system helps extend battery life and ensures smoother acceleration and controlled power usage, which can significantly improve real-world range.
Real-World Usage: How Far Can You Really Go?
While the Tambora AE is rated for 119 km, the actual range depends on external factors like terrain, rider weight, and riding style.
- Flat city roads with Eco mode: 100–119 km
- Mixed terrain with moderate assist: 80–100 km
- Steep hills with high assist: 50–80 km
By combining efficient riding techniques (which we’ll cover in the next section), you can push the Tambora AE to its maximum potential, making it a great choice for riders who want extended performance.
How to Maximize Your Electric Bike’s Range
Even with a high-capacity battery, an electric bike’s range depends on how efficiently you ride. Small adjustments in your riding habits can make a big difference in how far you can go on a single charge. Below are three proven strategies to help you get the most out of your e-bike’s battery.
Ride in Eco Mode Whenever Possible
Your e-bike’s assist levels significantly impact battery consumption. While higher modes (such as Boost or Turbo) provide extra power, they also drain your battery much faster. Eco mode, on the other hand, uses minimal power while still giving you a smooth ride.Riding in Eco mode can increase your e-bike’s range by up to 30% compared to higher assist levels. It’s ideal for flat roads and long-distance rides, where full motor support isn’t always necessary. You can always switch to a higher setting when facing steep inclines or strong headwinds, but returning to Eco mode afterward will help conserve energy.
Remove Unnecessary Weight
Excess weight forces your e-bike’s motor to work harder, consuming more battery power. This includes not only your body weight but also the extra gear, bags, and accessories attached to your bike.
Reducing your bike’s load by just 5 kg can add an extra 5–10 km to your range. If you’re commuting, pack only the essentials. If you’re touring, distribute your gear evenly to improve balance and efficiency.
Avoid Steep Gradients When Possible
Riding uphill requires three times more power than cycling on flat terrain, quickly draining your battery. Whenever possible, plan your routes to avoid steep inclines using navigation apps like Google Maps or Komoot.
If a climb is unavoidable, start with momentum and use a lower gear to reduce the strain on your motor. E-bikes consume far less energy when riders maintain a steady pace rather than relying on sudden power surges.
Final Thoughts
Maximizing your e-bike’s range doesn’t require drastic changes—just smart riding habits. By using Eco mode strategically, reducing unnecessary weight, and planning your routes wisely, you can extend your battery life and ride longer without worrying about running out of power.
It’s also important to remember that battery performance naturally degrades over time. Regular maintenance, such as keeping your battery at optimal charge levels and storing it in a cool, dry place, can help preserve its efficiency for years. Additionally, checking your tire pressure before each ride ensures that your e-bike moves efficiently with minimal resistance, further helping you save power.
Whether you’re commuting, exploring new trails, or taking on long-distance rides, a little planning goes a long way. By being mindful of these factors, you can enjoy a smoother, longer, and more energy-efficient ride—getting the most out of your electric bike every time you hit the road.
