Buying an electric dirt bike usually brings up more questions than simply:

“How fast does it go?”

Before spending more than $1,000 on a bike, riders and parents often want to know what it feels like to ride, how long the battery lasts, whether the battery can be removed, what happens in cold weather, how the speed modes work, whether it can handle rain, and how much maintenance it actually requires.

Those details matter.

That's why we've put together this QWAYQ EM04 FAQ and buying guide based on the questions riders most often ask before and after purchasing the bike.

The QWAYQ EM04 Electric Dirt Bike features a 2600W peak motor, up to 140 N·m of torque, a 48V 20.8Ah lithium-ion battery, hydraulic suspension, heavy-duty hydraulic brakes, 14"/12" wheels, and a listed maximum range of up to 53 miles.

But specifications only tell part of the story.

Here are the answers that can help you decide whether the EM04 is the right electric dirt bike for you.

Before You Buy: EM04 Rider Fit & Performance Questions

1. Who is the QWAYQ EM04 designed for?

The QWAYQ EM04 is designed for older teens and adults looking for a compact, higher-performance electric dirt bike for recreational riding.

It has a listed maximum load of 264 lbs and a recommended rider-height range of approximately 4.0 to 5.9 feet.

However, rider fit isn't determined by height alone.

You should also consider:

  • Leg length
  • Arm reach
  • Riding experience
  • Ability to control a 121-lb bike
  • Comfort when stopped
  • The type of terrain you plan to ride

For younger riders, appropriate adult supervision and protective equipment are essential.


2. How powerful is the QWAYQ EM04?

The EM04 uses a 2600W peak brushless motor and produces up to 140 N·m of torque.

For a compact electric dirt bike, that's a substantial amount of recreational performance.

The torque becomes especially noticeable during:

  • Acceleration
  • Uphill riding
  • Starting on uneven ground
  • Riding across dirt and gravel
  • Exiting slower trail sections

If you're coming from a lower-powered electric bike, the EM04 should feel like a meaningful step up.


3. How fast does the EM04 go?

The EM04 has a listed speed range of approximately 28–40 MPH depending on the selected speed setting and riding conditions.

Top speed can vary with:

  • Rider weight
  • Battery level
  • Terrain
  • Temperature
  • Tire pressure
  • Wind
  • Incline

A lighter rider on a flat, open surface may see different performance than a heavier rider climbing a hill.


EM04 Speed Modes & Controls

4. How many speed modes does the EM04 have?

The EM04 uses four selectable gear positions:

Gear 0 — No motor power
Gear 1 — Up to approximately 23 MPH
Gear 2 — Up to approximately 30 MPH
Gear 3 — Up to approximately 40 MPH

The rider changes gears using the + / – controls near the display.

This allows you to choose a lower speed setting when you want more controlled riding and move to a higher setting when the environment and rider experience are appropriate.


5. Why does the EM04 always start in Gear 0?

This is intentional.

When the EM04 powers on, it returns to Gear 0, where the motor will not drive the bike.

That reduces the risk of accidental throttle activation during startup.

Once you're ready to ride, select the appropriate gear using the + button.

This is a simple feature, but it's particularly useful on a bike with this level of motor performance.


6. Can the EM04 speed limit be removed?

No.

The EM04 does not support a user-accessible speed-limit removal function.

Riders should use the bike within its designed operating parameters rather than attempting to modify the controller or motor system for additional speed.


Battery, Range & Charging Questions

7. What battery does the EM04 use?

The EM04 uses a 48V 20.8Ah lithium-ion battery.

This battery is matched to the bike's 2600W peak drivetrain and supports a listed maximum range of up to 53 miles under suitable conditions.


8. How far can the EM04 go on one charge?

The maximum listed range is up to 53 miles.

However, this should not be interpreted as a guaranteed distance on every ride.

Electric dirt bike range is heavily affected by:

  • Rider weight
  • Speed
  • Acceleration habits
  • Hills
  • Surface conditions
  • Temperature
  • Tire pressure
  • Frequent stops and starts

Hard acceleration and high-speed riding consume considerably more energy than steady cruising.

Think of 53 miles as a maximum reference point rather than a guaranteed real-world result.


9. How long does the EM04 take to charge?

A full charge generally takes approximately 5–6 hours.

The charger indicator is:

Red while charging
Green when charging is complete

Avoid leaving the battery charging unnecessarily for extended periods after it is full.


10. Can the EM04 battery be removed?

Yes.

The battery is removable.

The seat can be unlocked with the key, and the battery can then be removed using the appropriate included tool.

This is useful for riders who:

  • Want to charge the battery indoors
  • Cannot park the entire bike near an outlet
  • Want to store the battery separately
  • Need easier access for maintenance or inspection

11. Can I charge the battery separately from the bike?

Yes.

The EM04 has a charging port on the bike, but the removable battery also has its own charging connection.

This means you can either:

Charge the battery while installed in the EM04

or

Remove it and charge it separately.


12. How long should the EM04 battery last?

According to the EM04 battery guidance, the battery is designed to retain approximately 80% capacity after around 500 full charge cycles under normal use and care.

A charge cycle doesn't necessarily mean plugging it in 500 times.

For example:

Using 50% of the battery and recharging it, then later using another 50% and recharging it, together count as roughly one full cycle.

Battery lifespan also depends heavily on storage, temperature, charging habits, and how deeply the battery is discharged.


Weather, Water & Storage Questions

13. Is the EM04 waterproof?

The EM04 has an IPX6 water-resistance rating.

However, water resistance should not be treated as permission to intentionally ride through heavy rain, deep water, or flooded areas.

Electrical components can still be damaged by improper exposure.


14. Can I ride the EM04 in the rain?

We do not recommend intentionally riding the EM04 in rain.

Even with an IPX6 rating, unnecessary exposure to water increases the risk of water entering electrical components.

If the bike gets wet unexpectedly, dry it properly before storage or charging.

Avoid pressure washing the bike.


15. Does cold weather affect EM04 range?

Yes.

Cold temperatures reduce lithium-ion battery performance.

You may notice:

  • Shorter riding range
  • Faster apparent battery drain
  • Reduced performance compared with warm-weather riding

This is normal behavior for lithium batteries.

If possible, store the battery in an appropriate dry environment rather than leaving it exposed to extremely cold conditions for long periods.


16. What should I do if I won't use the EM04 for a long time?

For longer-term storage:

  • Recharge the battery periodically
  • Avoid leaving the battery completely discharged
  • Check tire pressure
  • Keep the battery away from water and fire
  • Store the bike and battery in a dry environment
  • Inspect brakes and fasteners before riding again

The EM04 FAQ recommends recharging the battery approximately once a month during extended storage to help prevent excessive discharge.


Tires, Suspension & Ride Comfort

17. What tire sizes does the EM04 use?

The EM04 uses:

14-inch front wheel
12-inch rear wheel

This staggered wheel setup helps keep the bike compact while maintaining an off-road-oriented dirt-bike profile.


18. What tire pressure should I use?

For normal dry-weather riding on relatively flat ground, the EM04 guidance recommends approximately:

Front: 32 PSI
Rear: 38 PSI

Tire pressure may need to be adjusted depending on terrain, rider weight, temperature, and riding conditions.

Always inspect the tires before riding.


19. What suspension does the EM04 use?

The EM04 uses hydraulic suspension at both ends.

The front fork provides approximately 140 mm of suspension travel, while the rear uses a centrally mounted hydraulic shock with approximately 40 mm of travel.

The purpose isn't simply comfort.

Suspension also helps the wheels respond to bumps and changing terrain, which can make the bike feel more stable and controllable.


Brakes & Safety Questions

20. What brakes does the EM04 use?

The EM04 uses front and rear hydraulic disc brakes.

It also has an electronic motor cut-off linked to the brake levers.

When a brake lever is pulled, the controller cuts motor drive.

That means braking isn't only about slowing the wheels—the bike also stops sending drive power to the motor.


21. Does the EM04 have regenerative braking?

No.

The EM04 does not use regenerative braking.

The braking system is designed primarily around hydraulic disc braking and electronic motor cut-off.


22. Does the EM04 shut off automatically?

No.

The bike does not automatically power itself off after you park.

Always turn the EM04 off with the key and remove the key after riding.

This helps reduce the chance of accidental throttle activation.


Ownership & Convenience Questions

23. Does the EM04 have a mobile app?

No.

The EM04 does not require or support a mobile app.

Core riding information is handled through the bike's display.

The display can show information including:

  • Current speed
  • Battery level
  • Current gear
  • Odometer
  • Trip distance
  • Average speed
  • Maximum speed

For riders who prefer a straightforward bike without requiring smartphone pairing, this can actually be an advantage.


24. Is the EM04 foldable?

No.

The EM04 is not a folding electric bike.

At approximately 121 lbs, it should be treated as a substantial electric dirt bike rather than a portable commuter e-bike.

If you plan to transport it regularly, make sure your vehicle or transport setup can safely handle its size and weight.


25. Is the EM04 difficult to assemble?

Some assembly is required, and because the EM04 is heavy, having two people available during setup is recommended.

Important assembly points include:

  • Correct front-wheel spacer positioning
  • Proper handlebar alignment
  • Secure tightening of fasteners
  • Correct throttle positioning
  • Checking the brakes before the first ride

Never ride the bike if the handlebar, front wheel, brake system, or other critical fasteners feel loose.


Can the EM04 Be Used Off-Road?

The current QWAYQ EM04 is positioned as an off-road electric mini dirt bike, and trails, dirt paths, gravel, and outdoor recreation are central to its intended riding experience.

That said, “off-road” doesn't mean every terrain is appropriate.

Riders should still use judgment around:

  • Deep mud
  • Large jumps
  • Deep water
  • Extremely loose terrain
  • Very steep slopes
  • Terrain beyond the rider's skill level

A capable bike doesn't replace good riding judgment.


Can I Ride the EM04 on Public Roads?

Rules for electric dirt bikes vary significantly by location.

Vehicle classification, licensing, registration, age restrictions, helmet rules, and permitted riding areas can differ by:

  • U.S. state
  • Canadian province
  • City
  • County
  • Local riding area

Because of the EM04's performance and dirt-bike design, you should not assume that it is legal for normal public-road use simply because an e-bike may be legal in your area.

Check applicable local laws before riding.


How Should I Clean the EM04?

Avoid using a high-pressure hose or pressure washer.

For routine cleaning:

  1. Turn the bike off.
  2. Allow hot components to cool.
  3. Use a soft, damp cloth to remove dirt.
  4. Avoid directing water at electrical connectors, the display, battery terminals, or charging ports.
  5. Allow the bike to dry before charging.

A clean bike is easier to inspect for loose bolts, tire damage, brake issues, or other maintenance needs.


What Should I Check Before My First Ride?

Before riding the EM04 for the first time, check:

  • Battery charge
  • Front and rear tire pressure
  • Handlebar alignment
  • Front-wheel installation
  • Brake function
  • Brake-lever motor cut-off
  • Chain condition
  • Fasteners and bolts
  • Throttle return
  • Riding gear

Then begin in a lower speed setting and get familiar with the bike before using its full performance.


Is the QWAYQ EM04 Right for You?

The QWAYQ EM04 makes the most sense for riders who want:

  • A compact electric dirt bike
  • More power than a basic beginner model
  • A 2600W peak motor
  • Up to 140 N·m of torque
  • Multiple speed settings
  • A removable 48V 20.8Ah battery
  • Hydraulic suspension
  • Hydraulic disc brakes
  • A bike designed around recreational outdoor riding

It may not be the right choice if your main priority is:

  • A lightweight commuter
  • A folding bike
  • Smartphone app connectivity
  • Regenerative braking
  • A bike that can easily be carried by hand

Knowing what the EM04 doesn't have is just as important as knowing what it does.

That's what helps you buy the right bike instead of simply buying the bike with the biggest specification numbers.
