FAQ

What are the battery dimensions?: The battery is 235mm 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.

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.

How long does the battery take to charge?: Approximately 3.0 hours at the mains. The battery comes with a charger.

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.

Will Lvbu kit fit my bike ?: LVBU kit will fit most bikes except thru axle.

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.

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.

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.

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.

How much does the kit weigh?: The entire kit weights 9kg.

What is the range of the battery?: 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.

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;

Having reached our 60s we started looking into electric bikes for exploring the local area and expanding our choice of overnight stops by making getting into any town easy. We decided to go for a swytch kit rather than full electric bike partly to reduce nickability from the bike rack but also to make getting the bikes on and off the rack easier- more affordable e-bikes seem to weigh a ton. On our first test of this abroad, it's all gone fantastically well- once I got used to the idea that I still had to pedal for hills and couldn't just use the power as a boost. Most of the time on the flat I go power free but after a long day or uphill, I'll also pedal. I've only ever used 40% of battery which makes me think we could have got away with a less powerful kit, but we may do longer, steeper rides once my husband gets a kit next year. And it's great that I still have my ordinary battery- free push bike for use back home. Thank you for producing this brilliant product at an affordable price

I have been a customer for two years, having first purchased the all-in-one kit and now the new bottle kit. I want to thank the customer service team, which has always been courteous and prompt in their responses. Recently, I made a mistake in purchasing a cable, and it was replaced entirely at their expense. I can only recommend the lvbu e-bike kit to everyone for the product quality and the courtesy of the support team.Francesco

This is a great company with a great product, the kit which I have installed myself went thru two generations of LVBU kits at an age of 82 now I will be 86 in a few days. I have on the LVBU kit 3,250 miles on this wonderful bike kit. I even ordered the wrong pedal sensor and you replaced it without any additional cost. That's a wonderful company riding the mountain bike is so enjoyable. Thank you so much for a great product. I also had two hip replacements 6 years ago, so your kit is great for me having an electric bike.

Install had its challenges. After some improvising due to my bikes odd shape it’s in and I couldn’t be happier with the performance. Works great and the range is pretty good. I have the 6AH bottle battery and on mostly flat roads and using only the thumb throttle (no pedaling) I’m getting about 17 miles on a charge. Thumbs up from me.

Just what I needed. I have had some trouble with knee pain when climbing hills or biking fast and don't want surgery. The motor has helped a great deal. I am easily able to maintain 24-32kph on level surfaces including gravel trails, for up to 50km. On hills the speed drops, but still no pain and smooth climb at 2-3 times the speed I used to go.

I love the kit, there are some negatives but overall it's great. My kit did take a long time to arrive, much longer than originally quoted and i cannot track the status of the parcel during shipping, it really makes me nervous. Thanks god it finaly arrived after two months. I have used it almost every day now for over a year and haven't had any problems with it. The battery lasts well for my usage (a small amount up hill) and the install was very easy.

Fabulous bit of kit,All the advantages of a fully electric bike but at a fraction of the cost. Used for leisure only makes such a difference when going up hills. I am fully converted. Only downside is the cable is too long for my bike and all the cables have to be wrapped around the frame.

We are very pleased with the ebike conversion ! It was very easy to install, thanks to the easy to follow installation instructions. The additional performance boost is just what was needed. Rather than throwing away a perfectly servicable step through frame bike we have extended its useful life This system does not add much weight but has allowed attemting longer cycling distances with more confidence. The conversion kit is very cost effective with shipping by sea(but needs long time wait). We chose the optional LED display which includes a wireless throttle and ability to adjust assist levels. I can recommend LVBU.

Kit arrived ahead of schedule and is absolutely brilliant with high quality parts and comprehensive instructions. 10mm axle fitted perfectly and the whole set up took less than an hour. The motor engages smoothly with adequate power and range. As an older rider I can now manage 10% hill gradients once more on my beloved Fuji Touring but still pedal the rest of my 30 km route. So congratulations and thanks to all the lvbu team

Everything was smooth and fast, from the time I paid for the kit to when I got the kit, all in all in around one month I had it. I had questions about the sensors, what kind of kit I needed, and they were all answered promptly with pictures or a video to help me measure things on my bike. Installing the kit took around 1.5 hours all in all, I put in the wheel the wrong direction and the bike pulled back lol, so we had to take it back and turn it around. Once that was done, the bike works great, I rode it yesterday and it was fun, exactly what I needed. I think this is an excellent kit, light, my bike feels exactly the same as before without using the motor (it's mostly flat around here), and when I use it, it gives the push I was looking for when tired, or when going uphill so that i don't sweat on my way to work.

Well, realistically and overall I gave it 5 stars because it suits jy needs perfectly. If you are bike savy, this will be a breeze to install. But, even if not, the instructions and videos (read and watch before jumping in) are more than enough. For me, it simply makes riding a little easier and my trips longer. If you don’t want to use it, just keep it turned off. I think its worth it and a lot cheaper than a full eBike.

I highly recommend LVBU (Miya) for converting your bikes. I've been meaning to write a review for a while. Since I converted my bike with the motor kit, I now use my bike most days for commuting. I've had a great experience with Miya's service. When I was fitting the kit, I had a few questions about some of the fitting, and I received helpful guidance. It looks like fitting options have improved a little since I bought mine, so hopefully it's even easier for others now too. I also bought a second charger for my office (my commute is sometimes a little over 35km) . I ride my bike so much more now that I have that extra support. On the low assist level setting I still feel like I'm getting exercise - but I'm just moving faster and easier than I would have done without the motor.

This is the best bike investment I ever made!! So 1st off, the delivery arrived earlier than expected. They said October, & I got it in early September!! 2nd, the assembly was simple & straightforward. The only issue was the online instructions were not very clear. 3rd, the reason I got this was to make hills easier. Even 50% assist level settings, it still takes me uphill a LOT easier. 4th, average speed. Sure, it acts like an engine brake going downhill, , but the speed going uphill or coasting flat more than makes up for that!! My average speed used to be less than 10 mph, & now it's around 15 mph, meaning 50% speed increase!! I highly recommend getting this with the LED display. I haven't completely drained the battery before charging, but I'm guessing the range is at least 30 miles (maybe not 40 like advertised, but still good).
