How to Unboxing and Assembly U4 Electric Bike?

You can click the following link to watch the unboxing and assembly tutorial of U4 Electric Bike:
Unboxing and Assembly Video

How do I start the e-bike?

Press and hold the "M" button for 3 seconds to turn the e-bike on or off.

How do I change the speed mode?

The U4 model has four speed modes. Press the "+" button to increase the speed and the "-" button to decrease the speed. In the power-off state, hold the brake lever and press the "M" button for 5 seconds to change the speed mode to 35 km/h.

Why am I not achieving the speed/maximum performance I expected?

Several factors can affect the speed and performance of an electric scooter:

· Rider weight: A higher rider weight may affect the scooter's maximum speed.
· Terrain and slopes: Riding on hilly or uneven terrain may reduce performance compared to a flat road.
· Battery charge: A low battery may cause the scooter to limit speed or power to save energy.

Settings or riding mode: Check if your scooter is in a specific mode (e.g. Eco mode) that limits maximum speed and power. Switching to Sport mode or a more powerful setting may help.

If your scooter is still under warranty and you suspect a defect, we can arrange for further inspection and, if necessary, a replacement.

What to do if your brakes are not working properly, are not responsive, or are making loud brake noises?

There can be a number of reasons why your brakes are not working properly. Here are some common reasons and possible solutions:

· Brake failure or brake retardation:
Loose or worn brake cables can affect brake performance. Please check that the brake cables are properly adjusted and tightened.
Worn or damaged brake pads can also be the cause. In this case, they should be replaced.

· Loud brake noises:

Dirt or deposits on the brake pads or brake discs can cause noises. A thorough cleaning helps ensure smooth operation.
If the brake pads are badly worn or damaged, they should be replaced to eliminate the noise.

· Damaged brake pads or brake discs:
If you find obvious damage to the brake pads or brake discs, such as deformation or severe wear, they need to be replaced.
Please check your brake system for any of the above problems. If you are not sure, please send us a video or picture of your brake system so that we can help you further.

If the problem persists or cannot be solved by yourself, please let us know. We will take the necessary measures to repair or replace the defective part.

How to turn on the headlights?

After starting the electric vehicle, long press the "M" button to turn on the headlights.

Why are the specifications in the manual different from the actual product?

The specifications listed in our product manuals may sometimes differ from the actual product due to customs regulations and transportation policies in different regions. To ensure compliance and smooth delivery, certain specifications may be adjusted accordingly.

Easy to assemble.

I purchased this bike for my son and so far it looks and seems like a good quality item. The instruction was a little different from what I expected, but that's okay. I had to do less than what was instructed, so I'm happy with that.
Happy overall, let's see how it holds up after about a while.

Very happy with purchase

I got this electric bike to use for getting to and from work.I wasn't quite sure what to expect, but I was really pleased with what I found. The package arrived safely wrapped up to protect it from damage in transit.The assembly was really straightforward.I can still get back and forth from work with plenty of battery left. I've found the charging process to be really straightforward.
It fulfills all my needs and desires—charging capacity, speed, range, size, durability, and easy assembly. I also love its appearance; it has great traction and offers a smooth ride. I'm happy to report that the brakes are working perfectly. Everyone I've shown the car to and let test drive has loved it. It's really fun to drive! If you've been thinking about it, I highly recommend going for it. I'd give it 10 out of 10!

Love my E-Bike!

So initially this ebike caught my attention because it folds and makes transporting it convenient…I didn’t necessarily know much about them, but upon review from some of my friends who have ebikes, I found out that I own the beast of ebike! It’s been a pleasure riding and owning it! I would do it again if I needed to!

Bike is GREAT so far but customer service is even better!!!

I love my new bike U4. I had an issue, but they sorted it out for me. Customer service is great. We also bought 2 scooters and they are still going strong. We can highly recommend the iscooter bikes - they have plenty power, battery hold good and are a pleasure to ride.
