1. How to turn On/Off the front headlight?

Turn on the LCD display, hold the display button for 2-3 seconds, the headlight/LCD display background light will both be turned on.  Hold the power button the same way to turn it off.  


2. Can a child seat and Rear trailer be attached to the bike?

Yes. We highly recommend a child seat or a rear trailer for the Dolphin or the Beluga because they have a more robust battery capacity to tow the extra weight.


3. Could I change the seat(saddle) for a different one?  

Yes. If you find it necessary, you can buy a more comfortable or softer seat at your local bicycle shop or online. The seat mounts are universal to any standard bike seat.


4. How do I charge the battery?

The battery is charged by plugging the DC plug into the receiver located under the seat.  Once it is attached, you can connect the other end of the plug into an AC wall outlet.

If you can not place the bike next to a wall outlet, you can disconnect the battery connector at the seat post's bottom end. Twist off the adapter until it detaches, then open the seat post's quick-release lever and slide out the seat post. Then you can take it with you to charge as described above.

After charging the battery, you can slide the seat post back on the bike, use the quick release to adjust the seat to the desired height, and close the quick-release lever. Then reattach the twist connector to the bottom of the seat post and secure it tightly.


5. How far can Qualibikes go on a single charge?

Distance differs on the model, terrain, weight of the cyclist, and the power mode you are using (pedal only, full Throttle, or pedal assist). The typical range on our bikes is 25 to 50 miles on a single charge using primarily electric power. If you use the PAS, mileage can increase.  Some riders can achieve over 50 miles when cycling in pedal-assist mode.

Thumb throttle mode will engage the motor and consume battery power quicker.


6. What’s included in the package?

You will receive a package including:

Front and rear fenders, a kickstand, a charger, a thumb throttle, front and rear light, a tool bag, and a service card.


7. Will there be an additional freight charge?

Electric bikes shipped within the United States qualify for free shipping, which usually takes 2 to 7 days, depending on your location.

If you order from Canada/AK, please contact us at info@qualisports.us to confirm the shipping fee and the ETA date before you place an order.

If you are from Hawaii, please call
(808) 722-5454 / (808) 784-1055


8. Is the bike pre-assembled?

The front and rear fenders will take you 10 minutes to install; 95% of the bike comes pre-assembled. First, take the bike out of the box, remove packaging material, and unfold the bike; Then, connect the battery, and you can start riding right away. FYI, the battery is NOT fully charged, so watch out if you will ride far. If you have any questions while installing the fenders, contact us at any time at

info@qualisports.us - we will go back to you ASAP.


9. Is the bike water-resistant / Can I ride in the rain?

You can ride your Qualisports in the rain.  All of our electric components are designed to be water-resistant.  If you ride in the shower or very wet conditions, it is good to wipe the LCD display and battery and dry them to avoid overnight moisture, which sometimes can hurt electric parts.

Good maintenance makes your e-bike operate like new. Do not ride in deep water, especially when the water can touch the motor and the controller box. They are located at the bottom of the battery. When you notice the chain skipping or brakes not catching as before, take the bike to a local bike shop and get a brake and shifter adjustment or Tune-Up as you would with any non-electric bicycle.


10. When will the bike/accessories be shipped after ordering?

Once your order is received, a confirmation will be sent by email or text, it takes us 24 hours to prepare your order, and you will be notified as soon as it ships. Orders placed on Saturday/Sunday will be arranged on Monday.


11. Does the bike have a suspension front/rear fork?

No, it does not.  


12. What is the proper Tire Inflation?

Proper tire inflation is vital for the best performance of any Bike. Tire pressure is stamped on the sidewall of each tire measured in PSI (Pounds Per Square Inch). Do not over-inflate the tires. Fat tires do not require much air; they are designed to absorb bumps as a natural shock absorber.


13. Is there a warranty on Qualisports electric bikes?

You bet. Each bike comes with a limited warranty as follows:
The manufacture warrants Qualisports Bike frames and forks to be free from defects in materials and workmanship.
This includes a five years warranty on Frame and Fork.

Battery warranty: All Qualisports E-bike batteries come with a two-year warranty (Battery cycle lifetime is between 600 - 800 cycles depending on the environmental conditions) Qualisports will replace the battery if it fails within two years (as long as it was not damaged by personal neglect).

Consumables such as tires, tubes, saddles, grips, brake cables, pedals, and chains are not covered.

All other components and add ons such as racks will have a one-year warranty (Carry bags have no warranty). Please do note the limit of racks is 25KGs
