As you search for the right electric bike to cater to your urban riding needs, there’s a slew of factors to consider. The power of the motor, the ease of the ride, the range of the bike, and its weight are just a few. Nevertheless, one critical aspect that can’t be overlooked is the battery.
After all, it’s the heart of an electric bike. It supplies the necessary power to the motor, enhancing your riding experience. But with the market brimming with options, deciding on the best can be a complex task. In this review, we will test and review the best lightweight battery options for sport bikes primarily used in the UK urban environment.
1. Power: How much is enough for urban riding?
Before diving into specific battery options, it’s essential to understand how much power is adequate for your urban rides. The power of an electric bike is generally measured in watt-hours (Wh). In essence, a battery with a higher Wh will provide more range, enabling you to ride for longer periods without having to recharge. However, the trade-off is often in the weight of the battery.
For typical urban commuting, a battery with a capacity ranging from 300Wh to 500Wh will suffice. These batteries will enable you to travel between 30 to 60 miles depending on the terrain, the rider’s weight, and the level of electric assistance used.
2. Lightweight Batteries: Balancing weight and power
Lightweight batteries are increasingly becoming popular due to their portability and ease of handling. Weighing as low as 2 kg, these batteries can be easily carried around for charging, or to prevent theft when the bike is parked outside. Despite their lower weight, they don’t necessarily compromise on range, offering between 20 to 40 miles, which is adequate for most urban commuting needs.
The Tern Vektron with its 400Wh Bosch battery is a fantastic example of a lightweight yet powerful option. With an impressive range of up to 80 miles, it makes urban commuting a breeze. The battery tips the scales at only 2.6 kg, making it easy to carry around.
Similarly, the Brompton Electric has a compact and lightweight 300Wh battery. While it doesn’t offer the same range as the Tern Vektron, its 45 miles range is more than enough for most urban riders. It’s also among the lightest batteries in the market, weighing just 2.2 kg.
3. Pricing: How much should you spend on a bike battery?
The price of a bike battery can vary greatly depending on its capacity, brand, and type. However, remember that a more expensive battery is not necessarily the best fit for your needs. The key is to find a battery that offers the right balance between range, weight, and price.
For instance, the Bosch battery in the Tern Vektron is relatively pricey, retailing at around £600. However, considering its high capacity and lightweight design, it offers good value for money.
On the other hand, the Brompton Electric’s battery, which retails at around £400, offers a slightly lower range but at a more affordable price point. It’s a perfect choice for urban riders on a budget who still want a lightweight and reliable battery.
4. Battery Maintenance: Making the most of your investment
Maintaining your electric bike battery is crucial to ensure it lasts longer and performs optimally. Typically, lithium-ion batteries, which are the most common type of batteries in electric bikes, have a lifespan of 3 to 5 years. However, this can vary depending on how the battery is used and maintained.
Firstly, avoid completely draining the battery before recharging. Instead, try to recharge the battery when it falls to around 20% to prolong its life. Secondly, store the battery in a cool and dry place when not in use. Extreme temperatures, especially heat, can degrade the battery’s performance and shorten its lifespan.
Lastly, regular cleaning of the battery and the battery compartment on the bike will prevent dust and dirt from affecting the connections, ensuring the bike operates smoothly. Remember, taking care of your battery is an important step towards enjoying your urban rides to the fullest.
5. Safety: Ensuring a safe ride
Safety is paramount when dealing with electric bike batteries. In general, lithium-ion batteries are safe to use. However, they can pose a risk if mistreated. Avoid puncturing the battery or exposing it to water, as this could potentially lead to a fire.
Additionally, always use the charger provided by the manufacturer to recharge the battery. Using a different charger can result in overcharging, which is harmful to the battery and could potentially be dangerous.
Furthermore, when replacing the battery, ensure to dispose of the old one properly, as batteries contain harmful chemicals that are detrimental to the environment.
In conclusion, considering the power and weight, price, maintenance, and safety, you can select a battery that best fits your urban riding needs. Whether it’s the high-capacity Tern Vektron battery or the more affordable Brompton Electric battery, you have a choice that will make your urban rides more enjoyable and efficient.
3. Technological Advancements: A Game Changer in Battery Capacity
Technological advancements have been a boon for the electric bike industry, leading to significant improvements in battery technology. They have made it possible for manufacturers to develop batteries with greater capacity, thus extending the range of electric bikes without adding extra weight.
One such technology that has proven to be game-changing is the use of Lithium-ion (Li-ion) cells. Li-ion batteries are known for their high energy density, which allows them to store more energy without increasing their size or weight. These batteries are also known for their longevity and ability to hold their charge, making them the preferred choice for most electric bike manufacturers.
Another technology worth mentioning is the Battery Management System (BMS). This intelligent system monitors and manages the battery’s performance, ensuring it operates within safe parameters. It also helps prolong the battery’s life by preventing overcharging or deep discharging.
In terms of specific battery models, the Specialized Turbo Levo is a great example of an electric mountain bike that uses advanced battery technology. It boasts a custom 700Wh battery that’s integrated into the bike’s downtube, offering an impressive range of up to 60 miles. Despite the high capacity, the battery remains lightweight, making the bike easy to manoeuvre in the busy UK urban environment.
4. Performance: How Does Battery Capacity Impact Your Ride?
The battery capacity of your electric bike significantly influences your riding experience. A larger capacity battery will offer a greater range, allowing you to ride for longer distances without recharging. This is particularly useful for those who use their electric bikes for commuting or running errands in urban areas.
A good example is the Riese & Müller Load 75, a state-of-the-art cargo bike. It comes with a dual battery system that combines two 500Wh Bosch PowerPack batteries, providing a total of 1000Wh. This setup offers a tremendous range of up to 100 miles, which is ideal for urban riders who need to carry heavy loads over long distances.
However, it’s important to note that the battery’s performance can be affected by several factors. These include the terrain, the rider’s weight, the level of assistance used, and the weather conditions. For instance, riding up steep hills, carrying heavy loads, or using a higher level of assistance will drain the battery faster. Similarly, cold weather can also reduce the battery’s performance and range.
Conclusion: Choosing the Right Battery for Your Urban Ride
Choosing the right battery for your electric bike is crucial, as it greatly impacts your riding experience. The battery capacity determines the range of your bike, influencing how far you can ride without recharging. It’s also a significant factor in the bike’s weight, affecting its manoeuvrability and ease of handling, especially in an urban environment.
While deciding on the best battery, consider your specific riding needs. If you use your bike for short commutes, a smaller, lightweight battery like the one in the Brompton Electric may suffice. However, if you frequently go on long rides or carry heavy loads, you might want to opt for a bike with a larger capacity battery, like the Riese & Müller Load 75.
Remember, the key is to strike a balance between the battery’s capacity, weight, and cost. With the wide range of options available today, you’re sure to find a battery that’s perfect for your urban riding needs. So, take the time to research, test a few options, and choose wisely.
