FAQ

What is the range of the battery?

The battery is a high quality power lithium-ion battery, 36V, 8.7AH. The range is approximately 90 km+. But that does depend on many various factors, including terrain, slope, your weight and how much you pedal and your level of assist.

What are the battery dimensions?

The battery is 280mm x 75mm.

Can I put the battery in my pannier instead of attaching it to the crossbar?

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.

What’s included in the kit?

Wheel with 250W/350W motor, battery & battery holder, wired thumb throttle, instruction booklet, charger, tools for installation (allen key and wheel spanner).

Do I have to use the thumb controller?

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.

What if I don’t know my wheel/tyre size?

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 miya@lvbu.tech

Does the kit accommodate hydraulic brakes?

Yes it does. The kit will automatically sense when the brakes are applied and cuts the power to the motor.

Will Lvbu kit fit my bike ?

LVBU kit will fit most bikes except thru axle. 

How does Lvbu kit system work ?
  • Lvbu assist system is an intelligent assist system which can calculate out and provide the proper power based on the speed, acceleration, the slope of the road, and the assist level set in the APP or display. It will provide proper power automatically when you pedal. The motor will not work until the speed reaches 5 km/h. 
  • It will increase the power when it senses the acceleration is positive and decrease the power when it is minus. The system will also increase the power when going uphill and shut down the motor when going downhill. And the kit can also be controlled by the optional wireless thumb throttle. When you push the throttle, the bike will be fully driven by electric power, but when you release it the assist system will kick in again automatically. The introduction of the 5 assist modes is as following:
     * Manual mode: The most often used mode. The users can set a proper assist grade from 0 to 99 for themselves. 0 stands for no assist while 99 stands for the strongest assist. Under the manual mode the user can use the optional wireless display to set the assist grade instead of using smart phone. After setting the assist grade, the wheel will assist automatically.
     * Commute mode: Under this mode, the wheel will have relatively strong assist power all the time. The output curve of the assist grade is as shown above. It is similar to an assist grade of 60% in the manual mode.
     * Leisure mode: The assist power output is as the curve above. It is a curve similar to a damping ratio. Half an hour is a cycle. At the end of the cycle, the assist will become stronger.
     * Exercise mode: This mode has a small assist output. One cycle is also half an hour. After about 10 minutes, the assist power output will become stronger in the rest of the cycle.
     * Climbing mode: The wheel provides a certain assist grade only if the road is uphill that above a certain slope angle. The assist grade and the slope angle can be set in the APP. For example, when you set 2 degrees and an 80 assist grade, the wheel can give you an 80 assist grade when you are on the road with slope angle above 2 degrees.

     Note: Lvbu's intelligent assist system can be upgraded by the APP. We will keep optimizing the algorithm and publishing the new firmware.
How long is the lifetime of the battery?

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.

How to connect Lvbu kit with the APP?

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.

How does Lvbu wheel recognize uphill?

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: 

  • The purpose of calibrating the gyroscope angle is to give the gyroscope a horizontal reference, telling the gyroscope that the current angle is level, so that the gyroscope can detect the slope. 
  • If the gyroscope is calibrated on a downhill road, the gyroscope will regard the downhill road with a certain angle as a horizontal road, but when the bike is on a level road, the gyroscope will sense it as an uphill, in that case the motor will always provide assistance; 
  • If the gyroscope is calibrated on an uphill road, the gyroscope will treat this uphill road as a horizontal road. And when the bike is on a level road, the system will shut down the motor because the gyroscope sense the level road as a downhill road by mistake.

    Therefore, you must calibrate the gyroscope on a level ground, otherwise there will be problem with the assist system.
How to connect LVBU ebike kit with Bluetooth display?

BTC02 Display Connect Method:

  • Please turn off or disconnect the Bluetooth connection on your phone before the Bluetooth display connects to the LVBU Wheel. The wheel cannot connect to more than one device at the same time; 
  • Press the power button of the Bluetooth display to turn it on. Then press the power button three times continuously. The display will search for the Bluetooth address of the lvbu ebike kits nearby; 
  • After the display finishes the search, press the up and down keys to select the right address of your kit and press the power button to connect.

DW03 Display Connect Method:

  • Open the APP and connect it with the Lvbu ebike kit
  • Press the power button of the Bluetooth display to turn it on.
  • Tap the "device" icon at the bottom right in the front page of the APP-->Tap "Add Device"--> Select the display in the list to connect.
Do you have a local dealer or oversea warehouse?

Yes, we have oversea warehouse in Europe.

And for some countries, we do have local dealers. 

How long does the battery take to charge?

Approximately 4.5 hours at the mains.  The battery comes with a charger.

Can I buy a spare battery?

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.

How much does the kit weigh?

The entire kit weights 6.8kg.

Do I need a mobile phone to operate my bike?

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.

My bike has disc brakes – will the kit still work?

Yes, the kit fits both V brakes (sometimes called rim brakes) and disc brakes.

How does the pedal assist work?

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.

Why is there a maximum speed of 15.5mph (25 kph)?

The legal speed limit for e-bikes in some countries is 15.5mph.  Therefore the kit has a default maximum setting of 25kph. It is possible to manually increase the speed up to 35kph (22mph), but this should only be done on private land.

Is the import taxes included in the price? Do I need to pay taxes when I receive the ebike kit?

If the delivery address are in the countries below then you don't need to pay any taxes or VAT:

United Kingdom, United States, Canada, Australia, Russia, France, Germany, Italy, Spain, Sweden, Denmark, Ireland, Belgium, Netherlands, Czech, Republic, Austria, Portugal, Slovakia, Slovenia, Hungary, Bulgaria, Estonia, Greece, Poland, Lithuania, Finland, Latvia, Croatia, Ukraine.

Is Lvbu kit compatible with V brake?

Yes, Lvbu kit is compatible with rim brakes and disc brakes.

And a free new disc can be provided if you need.

Is it safe to use the front wheel drive?

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.

What are the functions of the APP?

The APP has two main kinds of functions as following: 

  • Set the parameters:
    ①Search and bind the Lvbu ebike kit: You need to search and bind the kit with the APP when you use it first time.
    ②Calibrate the gyroscope angle: The gyroscope angle must be calibrated after the first time you attach or reattach the kit to your bike.
    ③Set the assist mode or adjust the assist level.
    ④Set over-speed alarm.
    ⑤Set the maximum assist speed (speed limit).
    ⑥Lost report.
    ⑦Firmware upgrade.
    ⑧Restore factory settings.
    ⑨Set the wheel weight, load, wheel size, etc. ...
     After adjusting and setting the parameters, the system will automatically save values instantly.
  • Show cycling data:
    ①Riding speed
    ②Riding mileage: total mileage, current mileage, uphill mileage, etc.
    ③Kit model
    ④Bluetooth address
    ⑤APP version
    ⑥User instructions ...
    We are keeping optimizing the APP all the time, the new version of the firmware and the APP will be released from time to time, you can update it anywhere with the network of your mobile phone.

Do I have to connect to the APP while riding?

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.

What is lvbu kit warranty policy?

For battery, motor and controller, we provide one year warranty.

200 REVIEWS - KF30S Ebike Conversion Kit
Eugene
Hungary , 1/16/2025
As one of the few honest "plug and GO" electric wheel kits available, I have been 100% pleased with the product and my experiences using it. I purchased the kit after reading many reviews, and watching many YouTube videos, due to not only how easy it was to change over my bike, but everything was there ready to use, and didn't require me to have an electrician's degree as so many of the other kits demand. The sole reason for the purchase was to hopefully allow me to continue to enjoy biking while also allowing a damaged knee to recover. Thus far, after a number of delightful rides, it has been everything it promised to be - the motor is very discrete, very quiet in operation, and really does an excellent job taking over the lion's share of work to assist me up hills. As a matter of fact it has opened up new avenues of cycling for me for long distance rides, now that I'm no longer afraid of re-damaging my knee by unassisted cycling. I have a number of long bike rides on my calendar next Spring, and my electric wheel will be with me for all of the rides.

We moved from a dead-flat landscape in western New York to a very hilly part of the Las Vegas valley. Alas, the hills in my Nevada neighborhood made daily biking impossible and I longed for a solution. Luckily, I learned about the lvbu KF30S kit on-line and decided to try it after straining my back attempting to climb the hills at age 65. The bottle battery kit (700c size wheel) has enabled me to enjoy the ride again. I now look forward to my daily rides. The product is well engineered and the quality is superb. Just the right amount of "boost" when you need it on hills while still allowing you to get some exercise at the same time.

I received the kit in March. Busy spouse was able put on the wheel quickly and easily. I added the cables myself. We live in a hilly area of southern Ontario on the Niagara Escarpment. Had moved to a new part of the area which has low hills and level train crossings. Adding a motorized 26 inch wheel to my duffer mountain bike would be perfect.

Hello, I bought the conversion unit for my wives bike. After a install time of only about 15 minutes, I only had to change the wheel for her bike, it was up and running. I tested the bike for her for a few days before I sent her on her way. It met and surpassed all of my expectations. I watched and read many reviews online before ordering, so I had a pretty good idea of what to expect. After it passed my testing, I turned it over to Beth. Beth had seen me bike commute for the last 5 years , and wanted to try it herself in order to save money on gas, help the environment, get more exercise, and enjoy the pleasure of riding as I have. The problem was Beth has a chronic back pain, and it hurt her to put the force into pedaling all the time. After setting her up with the kit, on a bike that was comfortable for her, she has went from riding 4/5 times a year, to being a daily commuter. She runs all her errands by bike now. AWESOME job. The only thing that could be any better would be a bigger thumb trigger, it can be hard to tell if you are on the thumb trigger if wearing gloves.

United States of America , 1/8/2025
I’ve purchased 7 kits over the years, 4 for my wife and me and 4 for neighbors. I am actually installing a new 29” kit on my mountain bike today. I have the following observations: Over all the design, technology and quality of production are excellent and I often recommend this kit to others. It's a great and inexpensive way to convert an existing bike to an eBike. I especially like that there is only one cable connecting the controller to the motor. I've also used the Bafang kit which has a spaghetti bowl full of different cables. The improvement with the push button OFF/ON on the battery is a HUGE improvement over the old pinhole switch. A conversion kit-maybe something in the lid, to modify the pinhole switch to a push button OFF/ON would be very much appreciated. I’ve some ideas about this myself. I see there is a small circle on the battery lid where the ON/OFF button should go The display should have the option to switch from metric to imperial measurement units. I’m comfortable working in metric but many Americans aren’t The WePower app is very good but occasionally turns off on its own, requiring a reboot. This happens if I take a rest break of more than just a few moments when cycling I’ve had one battery failure. In fact this was the extra battery I bought with the first bike kit and it has never worked. I only found this out when I went to use over a year after purchase. I ordered a kit from Rao to “wake up” the battery. It did wake up the battery but then the battery immediately dies again I was unaware when I purchased my second kit that the old batteries do not work with the new controller. I think you should make the new controllers backwards compatible or make it clear to customers that old batteries will not work with new systems. Batteries are expensive so it would be good to be able to use old ones with new systems I have mixed feelings about the torque sensor. I don’t like the lag but think it reduces the stress on the drive system. Again, overall I think this is great technology, great quality and great customer service.

Just received the package..so far it is everything I expected...I live in a place that has nothing but hills, and I don't have the training to climb them on my bike. With the conversion kit I bought from lvbu guys, I bike everywhere now. I can climb, and still get a lot of exercise, as the kit helps me but doesn't replace me : ) I will recommend the kit to my friends, as it has the best price, and is easy to install, and does the trick!!

Have had the unit installed on the bike for approximately 2 weeks but have not been able to ride more then 10 miles due to time restraints. Relatively easy installation with good instructions from miya. At this point very pleased with the product. Much better then having to buy a completely new "electric " bike at $1000.00 on up.

I purchased the KF30 2 years ago. It has cut in half my commute time, and brought me up the steepest hills, like the ferry hill on Vashon's north end. It was a great investment, and was easy to convert my bike. I purchased one of the lighter batteries, so my bike is very rideable even if there is no power in the battery, and I can pick it up to put it on a bus. That expands my range considerably. Whenever you need help, the staff are always great. I highly recommend the kit, and the people.

This is a great hub! It has made my ride to work so much more pleasant. I get there faster, but more importantly, I get get there moderately dry rather than drenched with sweat. I also find myself riding for pleasure and to do little errands much more. Have had absolutely no mechanical or electrical issues in the year that I've had it. Highly recommended.

The 10 mile round trip commute in Houston, TX can leave me soaked in sweat, and I don't have access to a shower at work. This electric wheel provides the assistance I need to keep the perspiration at bay when the mercury rises. I'm really glad I pulled the trigger on this purchase.

I've put 2200 miles on my electric bike kit in 10 months and it has performed marvelously. It's been so much fun hauling my dogs around in their bike trailer with almost no effort unless I choose to.This kit has performed spectacularly from performance to customer service! I'm happy!
