The battery is 235mm x 75mm.
The battery holder must be positioned at an upward slope, therefore it’s best to be fixed on to your bike-frame. This is because there is a gyroscope inside it, which is part of the pedal assist technology.
No, using your mobile phone is your choice. If you want, you can download the Wepower app, where you can set the pedal assist mode, see the speed, temperature, battery level and mileage covered. But this is entirely optional, and the bike will function perfectly without it.
Yes, the kit fits both V brakes (sometimes called rim brakes) and disc brakes.
The kit has an “intelligent assist control module” which works in conjunction with a gyroscope calculating the power you need. It will assist you automatically when you are pedalling. The motor will not work until the speed reaches 5km/h. The system will increase the power when you go uphill and will shut down the motor when you are going downhill. When you brake, the system can detect the decrease of the speed, and will stop the motor.
If you push the thumb throttle the bike will be fully driven by electric power, but when you release it the pedal assist system will kick in again automatically.
Approximately 3.0 hours at the mains. The battery comes with a charger.
LVBU kit will fit most bikes except thru axle.
Yes, Lvbu kit is compatible with rim brakes and disc brakes.
And a free new disc can be provided if you need.
Yes, it’s safe to use the front wheel drive.
The power of the front wheel motors those lvbu ebike kit use are between 250w to 350w, so there is no safety problem. Actually, there are some advantages to using front motor drive:
It is more efficient to pull the bike compared to push the bike.
The front motor will balance the weight of the front wheel with the rear wheel to make it stabler
It is much easier to install the front wheel than the back wheel.
The APP has two main kinds of functions as following:
No, you don’t have to connect the kit with the APP when you are riding. The assist system is written in the controller, not in the APP. But before the first time you use it, you must calibrate the gyro angle for the bike.
You can set the assist grade in the APP and put your phone in your pocket. The kit will provide proper assist power for you automatically.
For battery, motor and controller, we provide one year warranty.
Yes. We find the vast majority of people don’t need a spare, but if you want to go on very long bike rides you can double your range by charging a spare battery and taking it with you. You can purchase a spare battery here.
Wheel with 250W/350W motor, battery & battery holder, wired thumb throttle, instruction booklet, charger, tools for installation (allen key and wheel spanner).
No. The thumb controller is your choice. We find that some of our customers prefer not to use the thumb controller and that’s fine, the bike will automatically work on the pedal assist mode.
This is a common question. Your tyre size should be written on the side of your tyre. There will be a series of numbers showing the diameter and width. It will look something like this: 700c x 38. Occasionally different cycle manufacturers will use a different scale. If you have any problems working out your tyre size, please call us on +86 199 7018 0785. Alternatively, you can email us a picture of the writing on your tyre to email@example.com
Yes it does. The kit will automatically sense when the brakes are applied and cuts the power to the motor.

The battery is a high quality power lithium-ion battery, 36V, 6AH. The range is approximately 60 km+. But that does depend on many various factors, including terrain, slope, your weight and how much you pedal and your level of assist.
Lvbu ebike kits use EV 18650 lithium-ion battery cells with class A quality. Working with our own BMS system, the lifetime of the battery is very high. 80% capacity remains after 1,000 cycles. So normally it can last 5 years.
*Note: The definition of one cycle is that charge the battery from 0 to 100% and discharge it fully. For example, if you charge the battery from the 0 to 50% and discharge it to 0, that is 0.5 cycle.
Open the APP and allow all the permissions that the APP asks for. And tap the magnified glass icon on the right top of the APP to search for the Bluetooth address. Select the right address of your kit in the list to connect.
*Note: Please connect the kit in the APP, don’t connect it in the operation system of the phone. You don’t need to input any pin to connect. And please make sure all permissions are allowed and the kit is not connected to other devices. The kit can just connect to only one device at the same time.
Lvbu wheel has a built-in six-axis gyroscope, which can sense the slope of the road such as uphill and downhill. But if you want to detect the slope of the road correctly, you must calibrate the gyroscope angle on the level ground first. The way how gyroscope works is as below:
