CHARGE
The short answer
Here is how to charge an electric dirt bike: let the battery cool after the ride, plug the charger that came with the bike straight into a wall outlet, and charge indoors on a hard, non-flammable surface while you are nearby. Unplug it when the charger shows full. By the makers’ figures, charge times run from about 1.5 hours on the Talaria Komodo 2025 to 10 hours on the NANROBOT KD2W14, and many makers quote a partial charge such as 20% to 80%. Never use a charger meant for another battery.
Use only the charger made for your bike’s battery. Its voltage must match the pack.
Charge times in our catalog run from about 1.5 to 10 hours, by the makers’ figures.
Many makers quote 20% to 80% or 90%, because the last part of a charge slows down.
Charge indoors, at room temperature, on a hard surface, plugged straight into the wall, and stay nearby.
A simple charging routine
The same few steps every time keep charging safe and easy.
Switch the bike off and, if the battery is removable, take it out and carry it to your charging spot.
Let it cool for a while after a hard ride, and let a cold battery warm up to room temperature first.
Look at the battery, charger and plugs. Dirt, water, bent pins or a damaged cable mean stop and clean or replace before you charge.
Plug in the charger in the order your manual gives, straight into a wall outlet.
Stay nearby and check on it now and then. Do not charge while you sleep or leave the house.
Unplug when the charger shows full, and refit or store the battery.
How long charging takes
Charge time depends on battery size and charger power. Here is what the makers list for bikes in our catalog, quickest first:
About 3 hours: the Talaria Sting MX5 Pro and the YVolt Surge V. Altis lists 3 hours for the Delta S from 20% to 80%, and 3 hours for the Sigma from 20% to 100%.
3.5 hours, 20% to 90%: the E Ride Pro PRO 4.0, SS 3.0 and SR.
Notice that several of the biggest bikes list the shortest times, so a small bike does not always charge faster. If a quick turnaround matters, check the charge time, and whether it is a full or partial charge, before you buy.
Why makers quote 20% to 80%
A lithium-ion battery fills fast in the middle and slowly at the top. Near full, the charger lowers the current to protect the cells, so the last part can take a long time. That is why E Ride Pro quotes 20% to 90% and Surron and Altis quote 20% to 80%. Altis shows the difference on the Sigma: about 2 hours from 20% to 80%, and 3 hours from 20% to 100%.
For a normal ride day, charging to full before you head out is fine. For storage, keep the battery around half charged, as we explain in our electric dirt bike range guide.
Matching the charger
The charger must match the battery’s voltage. A charger’s label shows its full-charge voltage, which sits above the battery’s nominal voltage. Riding’times pairs the 48V GT54 with a 54.6V 3A charger and the 60V GT54 Pro with a 67.2V 3A charger. Never swap them, even if the plug fits.
Amps set the speed. A rough rule: amp hours divided by charger amps gives the hours from near empty. The GT73’s 18.2Ah packs on 2A chargers work out to about 9 hours, in line with the 9 to 10 hours Riding’times lists.
Use only the charger that came with the bike, or a replacement or faster charger the maker approves for that battery.
Retire a damaged charger. A cracked case, a cut cable or a charger that runs very hot needs replacing, not taping up.
Where to charge
Indoors, at room temperature, in a dry space such as a garage or utility room.
On a hard, non-flammable surface, away from bedding, fuel, paint and cardboard.
Away from doors and escape routes, with a working smoke alarm nearby.
Straight into a wall outlet. Avoid extension cords and power strips. Altis lists a charging input of 110 to 120V at 12.5A for the Sigma, which is a big load for a household circuit, so do not share that outlet’s circuit with other heavy appliances.
Never charge a battery that is swollen, cracked, leaking, water soaked or smells odd. If a battery smokes, hisses or gets very hot while charging, unplug it only if you can do so safely, move away and call 911. Do not use it again, and contact us or the maker. Battery work belongs with a qualified technician; see our warranty page for covered faults.
On the bike or off the bike
A removable battery makes charging easier. You can carry it inside while the bike stays in the garage or truck. The Surron Light Bee X battery is removable, many E Ride Pro models use swappable packs, the NANROBOT GTR and Riding’times GT54 batteries come out, and the GT73 carries two removable packs with two chargers.
A charged spare is the simplest way to stretch a ride day: swap packs at lunch instead of waiting for a charge. Buy only the maker’s own battery for your model, and never fit a pack of a different voltage. Check the battery is locked firmly in place before you ride.
After a wet or muddy ride
Water and electricity do not mix at the charge port. After rain, a river crossing or a wash, dry the bike and let the charge port and battery contacts dry fully before you plug in. Wipe away mud from the port and connectors with a dry cloth. A water rating such as NAVEE’s IP65 for the Storm X helps on the trail, but it is no reason to charge a wet battery. Washing tips are in electric dirt bike maintenance.
Charging away from home
Most riding spots have no plug. Arrive with a full battery, carry a charged spare if your bike takes one, and plan shorter loops that bring you back to the vehicle. If your riding area or campsite offers power, use a proper outlet and the same habits as at home: a hard surface, shade, and someone nearby.
Never charge inside a closed, hot vehicle, and never leave a battery in direct sun. Our guide on how to transport an electric dirt bike covers the battery on the drive.
Habits that help the battery last
Avoid running it flat on a regular basis. Head back while there is charge left.
Avoid charging hot or cold. Room temperature is ideal.
Store it around half charged and check it monthly if the bike sits.
Keep heat away. It ages lithium cells faster than anything else.

Questions riders ask
How long does it take to charge an electric dirt bike?
By the makers’ figures for bikes in our catalog, from about 1.5 hours on the Talaria Komodo 2025 to 10 hours on the NANROBOT KD2W14. Many makers quote a partial charge, such as 20% to 80% or 90%.
Can I charge my electric dirt bike overnight?
We do not recommend it. Charge while you are awake and nearby, and unplug the charger when it shows full.
Can I use a faster charger on my electric dirt bike?
Only a charger your bike’s maker approves for that battery. A charger of the wrong voltage or an unapproved fast charger can damage the cells or create a fire risk.
Can I charge an electric dirt bike from a household outlet?
Usually, yes. Altis, for example, says the Sigma charges on a standard household outlet. Check your charger’s label and manual, plug straight into the wall rather than an extension cord or power strip, and avoid sharing the circuit with other heavy loads.
Should I charge my electric dirt bike to 100%?
Charging to full before a ride is fine. For storage, keep the battery around half charged and top it up monthly.
