Maximizing Your Ride: How Long Do eBike Batteries Last?

If you’re shopping for a new electric bike, one of the factors you look at is the battery’s capacity and range. And, if you look at enough ebikes, it can start to become confusing. After all, the same battery performs so differently across different ebikes. If you already have an ebike, you’ve realized the range listed isn’t necessarily the same one you’re getting. Sometimes it’s more, sometimes less.

So, now you may be asking yourself, “How long do ebike batteries last?”

And the answer is, “It depends.”

Why You Need to Know How Long Your eBike Battery Will Last

One of the reasons people love electric bikes is because they can ride further without tiring. However, you might be in a predicament if you are miles from your destination with a dead battery.

Knowing your electric bike battery’s range is crucial in planning your rides. 

Understanding What Impacts How Long eBike Batteries Will Last

Different electric bike manufacturers have their ways of determining how long a battery will last between full charges. 

First, you need to know the calculations used to determine the range of an ebike battery. Do you remember your high school math classes and wondering, “When will I ever use this in the real world?” The answer is “Now.”

Here is your formula: Wh = V x Ah

Wh = watt-hours

V = Voltage

Ah = Amp-hours

For example, suppose you are looking at a 48V/12Ah battery. You multiply 48 x 12 to get 576 Watt-hours. Of course, watt-hours don’t really tell you anything unless you know 1 mile equals approximately 20 watt-hours. Therefore, you divide the 576 by 20 and get 28.8, meaning that your 48V/12Ah battery will give you a range between 25 and 30 miles. If you don’t feel like doing the math, there are several online voltage charts that can help.

But that’s just an estimate. There are many other factors at play that make coming up with an exact number difficult.

So, what else influences your ebike’s battery’s range?


The weight of the rider and any cargo will impact how long your ebike battery will last. Carrying a heavier load requires the ebike’s motor to work harder, thus drawing more energy from the battery.


Riding uphill or on rocky trails requires more ebike battery output than riding on a smooth, level path.


Wind and cold temperatures both impact battery life. You may rely more on your motor when riding against the wind. And extreme cold severely diminishes your battery’s capacity.

Riding Pattern

Are you someone who pedals at a steady, consistent pace? Or maybe your route has several stops and starts, or you do a lot of quick accelerations. How you ride your electric bike also impacts how long your battery will last between charges.

To understand their range, let’s look at some of the best-selling electric bikes. 

Revi Bikes OG Cheetah Fat Tire Electric Bike

The Revi Bikes OG Cheetah Fat Tire Electric Bike has style. It looks like a vintage motorcycle that looks perfectly in place on either narrow city streets or wide country roads. It comes with a 48V/17.5Ah battery, allowing for a range of approximately 45 miles.

The Revi Cheetah has several great reviews, with several riders saying it’s the best electric bike they’ve ever ridden and an excellent choice for those who live in mountainous areas or have bad knees.

Green Bike USA GB Low Step Folding Fat Tire Electric Bike

Another electric bike that’s popular with riders is the Green Bike USA GB Low Step Folding Fat Tire Electric Bike. The step-through frame makes it easy for people with balance or mobility issues to mount and dismount. 

It’s an excellent commuting ebike, especially for city streets with multiple stops. The fat tires go on grass, sand, or snow so that you can ride it year-round. It has a 750-watt motor and nine levels of pedal assist.

The 48V/18.2Ah battery provides up to an impressive 60-mile range, depending on the amount of pedal assistance. When you reach your destination, this electric bike folds up easily for carrying and storing.

Rambo Rebel Fat Tire Electric Hunting Bike

If you want a bike with power, speed, and range, look no further than the Rambo Rebel Fat Tire Electric Hunting Bike. The Bafang 1000-watt electric motor provides 1500 watts of power at peak performance, up to 28 miles per hour. Add a cargo trailer to the Rambo Rebel, and you’re ready to ride deep into the woods or the most rugged terrain to camp and hunt. 

The 48V/21Ah lithium-ion battery gives you 48 miles of range, making it the perfect electric bike for your daily commute into the city or climbing steep mountains on the weekend. Many ebike riders say the Rambo Rebel is a game-changer.

Hacks to Maximize Your eBike’s Battery Life

Over time, your ebike’s battery will start to lose performance. You may notice that you’re no longer getting the range you previously had. Since ebike batteries are expensive, you will likely want to avoid replacing yours as long as possible.

Whether your ebike battery is new or you’ve had it for a few years, here are some tips to help you prolong your ride per charge:

  • Lighten your cargo load
  • Make sure your tires are inflated to the correct psi, and you are using the right size tires for your ebike
  • Ride slower
  • Match your speed to the level of pedal-assist
  • Perform regular preventative maintenance on all of the bike’s components, not just the electrical ones.

Furthermore, you can upgrade the battery on some ebikes, but you must check with the manufacturer’s specifications first.


1. What Type of Battery Is Best for eBikes?

Early electric bikes used lead-acid or Nickel-metal hydride batteries. However, Lithium-ion (Li-ion) batteries are now generally considered the best option for ebikes. 

2. What Is the Average Range of an Electric Bike on a Single Charge?

The voltage and amp-hours of a battery can give you a general range of how far you can ride on a single charge. But the specific model of the ebike and other factors can impact your riding distance. 

3. How Do I Care For My Electric Bike Battery?

You can help extend your ebike battery lifespan and performance with proper care and maintenance, such as:

  • Charge the battery regularly and try not to let it fully discharge before recharging it.
  • Keep your ebike battery clean and dry, especially after riding in wet or dirty conditions.
  • Store your battery in a cool, dry place.
  • Avoid overcharging your battery. Most have a battery management system. However, you should unplug it once it’s fully charged.
  • Ride your ebike routinely, as the batteries tend to last longer when used regularly.
  • Follow the manufacturer’s instructions for charging and maintenance of your ebike battery.
