Best Kuberg Freerider Battery Upgrade Options

There’s no doubt that the Kuberg Freerider is an awesome electric dirt bike, but its battery won’t get you to (and from) the middle of nowhere. Luckily, you can upgrade the Kuberg Freerider battery to extend its life. We’ve got the best Kuberg Freerider battery upgrade options (plus everything else you need to know).

Can You Upgrade Your Kuberg Freerider Battery?

Kuberg Freerider batteries can be upgraded if you replace them with 48V models. 

A battery with a voltage of less than 48V will cause the Freerider to fail, according to the Kuberg user manual. It’s pretty common knowledge, and Kuberg warns about it in all their manuals.

It’s okay to use a battery of any Amp hour (Ah) as long as it doesn’t have a higher voltage (V). The “Ah” rating reflects your battery capacity. Having a higher “Ah” rating means your bike’s battery will last longer. 

Basically, you can change the amp hour of a battery, but not the voltage. However it always depends on the cell type and its maximal and continuous discharge currents. You can have a battery pack with higher Amp-hours, but it does not mean the cells will hold the output power required by ECU, otherwise, the ECU can switch the motorcycle off. 

The Kuberg Freerider battery can be upgraded by replacing its original 48V battery with another 48V battery with a higher “Ah” rating.

Kuberg Freerider Battery Specs

First, let’s take a look at the main specs of the Kuberg Freerider battery.

Voltage 48 Volts
Amp Hours 20 / 30 Ah
Watt Hours 1065 Wh
Charge Time 2.5 Hours

Kuberg’s Freerider battery is a trapezoidal power pack that sits under the seat post.The electrical system peak power is 8, 12, or 14 kW, the motor is the same in all Freerider versions, except for the Street version. The same battery can supply all ECU versions.

Simply plug it into a 110V or 220V electric wall outlet in your garage to recharge the battery.

Kuberg Freerider batteries are easy to swap, and we like that. Swappable means replaceable… and upgradeable! Simply take the seat off and disconnect the battery from the frame.

How Long Does a Kuberg Freerider Battery Last?

In terms of battery life, the Kuberg Freerider isn’t the champ you might expect (and there’s a good reason for it, which we’ll explain shortly). 

An adult weighing 75kg (165lbs) can ride for about an hour on the 48V 22.2Ah lithium battery and hit speeds as high as 70km/h (43mph) in average conditions. 

As with any off-road machine, the actual riding range and time depend a lot on the trail, so it’s hard to give a universal number. However, most riders get at least an hour out of their Kuberg Freerider battery.

For those dirt adventures that don’t last an hour, you can always upgrade the Kuberg Freerider’s battery. Sounds interesting? Just hang in with us, we’re getting there soon.

Kuberg Freerider Replacement Battery

There’s one solid reason people will have to replace their Kuberg Freerider batteries at some point – they don’t have a long service life. It’s not because it’s a bad battery, it’s because it’s great! 

In order to provide the Freerider’s adrenaline-pumping ride, the Kuberg Lithium battery squeezes everything out of its cells.

Due to its high amp output, which is one of the highest on the market, it’s totally natural for the Kuberg Freerider battery to have a shorter service life.

At some point though, the battery has to be changed.

How to Replace the Kuberg Freerider Battery?

It’s not hard to replace the Kuberg Freerider battery. Changing the battery is a very clean job, and you don’t have to get your hands dirty.

Here’s what DIY fellas need to know:

  • Turn off the power.
  • Remove the two bolts located under the rear fender. 
  • Remove the seat by sliding it backward.
  • Take a photo of the position and direction of each wire terminal. It’s important because you’ll later have to reconnect each of the battery wires to the correct bike terminal while installing the new battery. Kuberg warns that incorrect connection of the battery wires to the terminals may cause irreparable damage to the electrical components.
  • Unplug the battery connectors one by one. 
  • Carefully lift the battery pack by clearing the positive and negative wires out of the way. You can push them to the front and sides of the bike.

That’s it, you’re done. The battery can now be reinstalled by reversing the above steps.

  • Output: 48V 20Ah
  • Type: Lithium-ion

Unit Pack Power’s 48V 20Ah lithium-ion battery is the best budget replacement battery for Kuberg Freerider.

The only drawback is that it takes 6 hours to charge with its 4A charger and will only fit if you modify your bike. These downsides are more than made up for by its bargain price and long service life.

Looking for something heavy-duty but affordable? Here’s another option.

Shunbin High Power Upgrade Battery

  • Output: 48V 40Ah
  • Type: Lithium-ion

It does have some downsides, though. The first thing you’ll notice is that it’s pretty bulky at 22lbs (10kg). Secondly, this rectangle battery wouldn’t fit in Kuberg’s trapezoidal space without the help of a crafty bike tech.
