FAQs

Clean Arrow FAQ

How to start the vehicle after turning on the engine？

Sit on the bike, hold both ends of the handlebars, slide your feet hard, and then press the accelerator on the right handle to start the bike.

Can the vehicle fit into the trunk of a car?

The unfolded size of KB08 is 920*380*550mm (36.2*15.0*21.7inch), which can be placed in the trunk of an average family car.

If I weigh more than 66lbs, can I ride your bike?

This bike is designed for children. If your weight is slightly over 66lbs, it is not unusable, but it will affect the vehicle's load capacity and endurance. If your weight exceeds 30kg, it is not recommended to use this bike.

What is the ampere rating of the vehicle's charger?

The charger that comes with this car has an output voltage of 25.2V and an output current of 1A.

How to clean a vehicle? What should I pay attention to?

Be careful not to rinse or soak directly with water. If the car body is dirty, you can use a wet paper towel to gently wipe it, and be careful to avoid the battery interface.

My 4-year-old son is obsessed with this bike. It is absolutely perfect. He went from a strider to this, so he already had the balance down, and this is the next stepping stone before we put him on a dirtbike (he is too short for a dirtbike currently). The speed is perfect, the battery is great so far, and he has so much fun on it! The 5th wheel seller is amazing, too. wonderful customer service when you reach out to them

works as described

This was fairly easy to put together. I am not mechanically inclined, but figured it out. My kid was so ready to use it right when it arrived. There was some charge in it even though I charged it up before use. Nice sturdy anti-slip pedals, and the balance bike does exactly what it should be doing. My child is 6 and is 55 pounds. She rides and fits on it perfectly. Smooth ride, and the battery pack is removable, so they can use it without electricity, which is a great option. The seat adjusts quickly when needed, and the brakes work tightly. The battery charges really fast and lasts a few hours until it's done playing with it. Nice strong frame and looks adorable going down the road.

Happy with my purchase

My 4-year-old is enjoying this bike. Especially as a child who has both an ATV and a dirt bike. I'm glad I bought him this item. It only took 2 weeks now; he can ride his big bike with no training wheel, but he still rides his balance bike; it's his favorite.

My grandson actually really loves this bike, so glad that I bought it for him. Thanks. for a wonderful present for my grandson. The support team has also been great to work with as we navigated getting a new charger, as we lost ours!

We got this for my 3-year-old as an early 4th birthday present. He loves this thing! He figured out how it works and how to change the speeds right away. It goes at a good speed. It's not crazy fast or too slow. It's a perfect size for him. My older son, who's 7, also could ride it. The battery lasts for a few days of him riding, and he rides it a lot. It was a good price, and I would highly recommend it for any little kids who want an electric strider bike.
