Developments in E-Scooter safety for pedestrians

Developments in E-Scooter safety for Pedestrians

Developments in E-Scooter safety for Pedestrians

E-Scooters are here to stay and as we have discussed in many earlier blogs the safety of the driver rests mostly on the well-lit and good quality escooter with proper components – but what about the safety of others like pedestrians and vision impaired?

Well, just as there have been developments in electric cars and buses those same technologies are being researched to be used in electric scooters – the main focus is on sound.

As electric scooters are like other vehicles using electric motors are practically silent it can be difficult for pedestrians to hear them coming and if they can’t see it either for example the scooter is coming from behind then there is a chance of accidents.

As bikes also have this problem we have had a time-proven way of letting people we are coming – the majestic ringing bell. Most escooters are already equipped with these but so are cars and other vehicles and some have deemed it not enough.

New research is on the way

Now the researchers at the University of Salford are developing a universal scooter sound to be played out from speakers when the scooter is being ridden. Sounds simple enough right? Actually, it seems that they are testing what sounds would work best considering the noise and annoyance level while also making it easier to understand the traveling speed and distance of the approaching object.

Annoyance is an important factor as if the scooters are not detected well enough the sound is useless and if it’s too annoying living in a city full of continuously beeping scooters would be a nightmare.

Other than that the approaching a vehicle feeling is important. Like traditional motor-powered vehicles with their noise are quite easy to tell where they are coming from and how fast. It seems that the scientists have chosen a combination of sounds to create a similar audio output as cars which they call broadband emulating the sound space of motor and tires.

Who knows maybe this kind of sound attachment will be added to scooters in the future or if they become a legal requirement in-built in scooters. For sure this kind of research will continue and there might be a chance of being creative with sounds as well. The traditional motor sound might be just a bit boring and it’s the first result.

If we know the combination of sounds needed there should be space to make your ride a bit more personal – or how does a scooter sound like a space rocket or futuristic digital hoverboard sound?

In any case, we here at Langfeite are always supporting and following the latest trends in electric scooter safety as our goal is to give everyone a pleasant experience with the escooter lifestyle – be it rider or pedestrian.

So why not take a look at Langfeite’s escooter lineup and contact us today? They might not sound like sports cars yet but who knows what the future holds!

Electric Scooter CAD design and manufacturing from Langfeite

Stem is an important part of escooter CAD

Langfeite C2 electric scooter is here!

Electric Scooter CAD (Computer aided design) and manufacturing

Langfeite helps you to bring your ideas to life. Whether you already have a finished design of electric scooter that you want to manufacture or if youare in the early stages and need help to finish your designs you can contact Langfeite and we can help you to get it done.

Stem is an important part of escooter CAD

What does designing an escooter involve?

In previous blogs we have discussed on what parts are needed in electric scooter (What are the parts required to manufacture an electric scooter? and What do you need to know about electric scooter batteries?) but how do you do the actual design.

That’s where CAD comes in, just like almost all machinery in the world electric scooters are first designed with a computer using CAD software which can also be used for calculating the strength of the design.

Important parts are the battery compartment, forks and most importantly the stem locking and axel as those are the parts that have to take a lot of strain from the weight of the scooter. To make sure your design is secure you should work with professional designers and engineers. At Langfeite we have designed numerous electric scooters and other mobility products over the years and our team has a lot of expertice on how to make products not only secure but ergonomic and easy to use.

Safety first is always the guiding principle but after that comes the fun part – designing your own cool scooter that works for your clients. Stem and deck size to match the rider, correct wheel size and compartment, ground clearance – is the scooter for city or off-roading – lights and wiring. All these parts of the scooter have to be well designed so that they function as expected. 

For electronic devices like scooters it’s not only the main components that need to be places but one of the challenging part can be the wiring, will you build your wiring inside the stems for example or leave it out to make a simpler and cheaper design. Outside wires are also easier to replace if needed but hiding them makes the scooter look much more streamlined.

All the main parts like motor, throttle and battery need to be controlled aswell. For this there is a separate controller board in the scooter or it can be built in to other parts like the battery itself for example. If your scooter has special features or lighting you might also need PCB (printed circuit board) and hardware engineering design.

So all in all to design a scooter you will need a team of professionals CAD, PCB, Structural and Electrical engineers without forgetting the cool industrial designers to make your scooter look absolutely rad. 

For all these needs and more Langfeite can help. Our experienced team loves making scooters and we are always eager to work with people who share the same passions. So contact Langfeite today and lets make your design come to life!

Differences between Off-road and City scooters

Differences between Off-road and City scooters

Differences between Off-road and City scooters

First, let’s start with the definition, roughly the two types can be divided depending on the terrain they are built to ride on. City scooters, are generally meant to be driven on relatively smooth surfaces with maybe just a couple of expected bumps here and there like a speedbump you can see and get ready to ride over. It’s important to note that a smooth surface doesn’t mean flat as many city scooters including Langfeite have a lot of power from dual motors which are especially put there to tackle hills. Actually, scooters are very popular in hilly cities like San Francisco.

So if the city scooters have the power why do we need special off-road scooters? Well, it’s basically about the ground clearance, traction, and having suspension ready for much harder bumps and potholes you’d see in the city.

C8 City version has 8″ road tires.

First off the tires are switched from smooth and easy-rolling city tires to nubbed ones. While slick tires with some channels to direct water are the best for smooth surfaces due to them having less resistance for movement they are pretty much useless on loose surfaces like sand and mud.

This is where bigger and nubbed tires come in, basically, you sacrifice some of that smooth rolling to increased traction. The large nubs of the tire dig in deeper to the surface making it possible to ride in these demanding conditions and the larger size doesn’t go deep into potholes so easily.

Another point is the suspension. As city scooters usually opt out of spring suspension as they are effective, light, dependable, and cost-effective to make. Basically, they are perfect for city scooters and the hydraulic suspension is normally seen only on off-road or particularly heavy super performance city scooters.

Hydraulic suspension is superior to spring suspension in reaction speed, smoothness, and perhaps even reliability – although that is debatable – the main reasons they aren’t in normal city scooters are that they need more space, are more expensive, need more maintenance, but to put it bluntly, they would be an overkill for riding in the city.

When Off-roading the increased performance of the hydraulic suspension really makes sure that the wheels stay on the ground where there is traction and decrease the shock from bumps, holes, and rocks when you ride thus helping you to maintain the control of your scooter.

Finally the ground clearance. With city scooters, you actually want the least amount of ground clearance possible. It’s the same reason as you see with Formula 1 and sports cars. Having the center of gravity as close to the ground as possible results in better control of the ride, especially in corners. This is also the reason why electric cars and scooters both prefer to place the batteries on the bottom of the car / in the deck in scooters – check out last week’s blog if you want to know more about escooters batteries and their placement options.

C3 also has a 10″ Off-road tire version

Again the Off-roading scooters do a trade-off, they increase the ground clearance a lot at the expense of high speed and cornering performance. While it’s true that an off-road scooter would do worse when competing with its own lowered and slick wheeled model the city model would be useless on rocky roads even with nubbed tires.

The ground clearance is there so that your scooter doesn’t literally hit the ground and rocks when you hit those bumps or even when you are riding over a rocky area to reach the top of the hill. Even on mud, the increased clearance helps you not to get stuck and not get your deck covered in mud so easily.

Summa summarum Off-road scooters trade in weight, cornering, and smoothness for better suspension, traction, and ground clearance. City scooters then are really for cities.

Lastly, there is a middle path between these two extremes. As most of us get an escooter for commuting in urban areas and the off-road fun is reserved for weekends and holidays we at Langfeite have designed our new 2022 line up to have pure city scooters and midway models that have respectable ground clearance, nubbed tires while maintaining lighter weight with spring suspension and good handling in corners.

Langfeite’s new lineup has the right model for all commuters and those who want to have some off-road fun with their scooters in their free time. Dealers check out our models and contact us for quotations today.

What do you need to know about electric scooter batteries?

What do you need to know about electric scooter batteries?

What do you need to know about electric scooter batteries?

One of the main components of escooters is the battery. As the thing powering the scooter it influences multiple things like your speed, acceleration, range, and working time. For long-term use, the choice of battery also affects the cost per charge and maintenance costs of the scooter. Let’s take a look at the two main things you should know about escooter batteries without going too deep in the battery tech.

Battery Voltage and Capacity

The most common choice for escooter batteries is Lithium-Ion batteries. The smaller escooters can use as low voltage as 24V and the super-fast close-to motorbike size scooters can even go as high as 120V which is the same as some local power grids might have! This voltage is essentially linked to the motor of the bike so basically the higher the voltage the more power the motor has.

The capacity of the battery essentially means how much power it can store. From this aspect, the common choices range from 150 to 750Wh but again there is basically no limit and the bigger the scooter the bigger capacity batteries can be stored. This is because the power is stored in individual cells inside a battery – similar to single-cell AAA batteries you might know, so they are heavy and take up space. For powerful scooters, you can fit and carry more.

Charge times for batteries are often planned to be around 5-6 hours so you can comfortably charge them during a normal workday or overnight while you sleep. The lifetime of most batteries is the same as you would have your mobile phone. The best capacity is for the first 2-3 years and after that, they start to hold increasingly lower charges.

Battery placement

Langfeite C1 features a 60V battery

Normal placements for batteries are either the stem or the deck. Shared scooters often use the stem as it gives easy access, lighter capacity batteries can be fitted without compromising the control and the deck is easy to design as it doesn’t need to hold a battery.

Most scooters sold in shops on the other hand have the battery hidden in the deck as it’s a safe place and can hold a bigger battery with ease. As the weight of the battery is substantial it’s also better to have a lower point of gravity as it makes the ride more stable and the scooter easier to control – this is the reason why electric cars also place the battery under the vehicle and as close to the ground as possible, it gives superior handling and sports-car-like feel and cornering.

Basically, the deck is the best place to put the battery but the stem is cheaper. Although the deck also has its negative side – heat. One of the main reasons why scooters don’t get the highest waterproofing ranks is the battery and its placement. The more powerful scooters we mentioned have the battery in the deck but as they also generate heat that batteries absolutely hate the deck must be designed to dissipate that heat effectively enough. This in general means that sealing the deck is very hard to do while maintaining good enough cooling. Letting the battery breathe and designing a good enough waterproofing is a task that all scooter manufacturers currently need to balance.

Future of batteries

The heat, waterproofing, capacity, and power all are sure to develop fast. As most tech like bikes, scooters, cars, phones, computers all rely on batteries the development speed has been mindblowing already. You might feel that we haven’t come so far as for most people the battery they know the best is in their phones and the use time has actually come down from the times of those black and white screened Nokia’s but we can’t forget how much the batteries actually do in new tech. Those old tech batteries wouldn’t last more than a few minutes on phones or a couple of kilometers in escooters.

Taking from the fact that all those tech companies and users are all aiming to bring consumers ever-better batteries we are sure to see lighter, waterproofed, and high capacity batteries in the future!

Langfeite rigorously tests all its batteries and uses only premium-level batteries in its scooters. Contact us today and we are happy to talk about your escooter needs and what kind of batteries suit your needs.

Electric Scooter Interest on the rise Spring 2022

Electric Scooter Interest on the rise Spring 2022

Hi all, if you have been reading our blog before you might know that we here at Langfeite electric scooters have been very excited about the coming spring and summer. Escooters sales have grown every year and there’s no reason that this wouldn’t be a great your as well. More and more people have experienced riding scooters – be it their own or a shared one – and appreciate the convenience escooters can bring to their lives.

It’s a well-known fact that Spring is when the escooter and bicycle markets are heating up, just take a look at the interest in the escooter topic on Google Trends Worldwide.

Worldwide Escooter interest 2021-2022

The low point of February has passed and we already see a spike up as the northern hemisphere is experiencing warmer weather and spring has hit the town. The peak will come later during the year in July when the holidays seasons start.

This is why we updated our lineup for 2022 during the winter and you can see our full lineup of off-road and city scooters on this webpage. Naturally, we have our older and many different kinds of OEM models plus the ability to design completely new models that would suit your needs – Just contact us and 

If you are interested in how escooter seasons peak in your market you can also use Google Trends. For example, in the USA the peak interest happens as late as November but one of the big reasons for that is the holiday and Black Friday deals.

USA 5 Year Escooter Interested is on the rise.

In Germany where escooters are a newer phenomenon, the graph looks much different as the interest has been growing fast and only just this year the spring peak is higher than past years’ which happened at different times. This would align with our estimates that Europe as a market is going to grow a lot this year as people are aware of the product.

Germany Escooter interest 5 years

No matter where you live there’s a high likelihood that escooters are going to hit the streets near you this year. So act now and take the advantage of working with Langfeite electric scooter manufacturing.

How does Langfeite manufacturing test electric scooters?

Electric Scooter Manufacturing and Testing

How does Langfeite manufacturing test electric scooters?

To ensure the highest quality of our products design and manufacturing all our scooters and prototypes get comprehensive testing before they hit the production line and naturally after that they go through QA as well.

Here are the main types of tests that are involved in electric scooter manufacturing that are mechanically tested and not just digitally simulated. These tests are performed at our factories and must be passed before mass production. Let’s take a look at what they are.

Langfeite Electric Scooter Prototype Testing.

The main parts getting tested are the electric motor, springs, brakes, and electronics. Integrity and performance are the focus of the tests. 

Main types of escooter manufacturing tests:

  1. Temperature and humidity testing. Parts of the scooter get tested that they operate as expected in extreme riding conditions such as low and high temperature, dry and high humidity. 
  2. Pressure test – Stress resistance and pull ability of escooter parts. The motor hubs get tested for high-pressure resistance and the shock absorbers get tested for pull ability: for example, spring suspension handles to pull and maintain to right alignment and well-performing suspension at all times.
  3. Dust testing – Tests the dust resistance of the motor. E-Scooters must be able to handle dust in large quantities. Especially Off-roading will lift lots of dust and riding in the city isn’t exactly dust-free either. Our tests ensure that the motors don’t get filled with dust. Thanks to the design and low wear of electric motors they are maintenance-free after well enclosed.
  4. Test motor output power. Langfeite motors are meticulously tested that they fill the performance requirements set for them. 
  5. Motor balance and alignment test. The base rock of any solid ride is that the motor is running aligned and smooth – otherwise, you would be doomed with a terrible ride.
  6. Waterproof IP test with a water pressure machine. It’s done exactly as it sounds, pressured rain shoot at the part from multiple directions. Simulating rain, washing, etc. The main focus is on the motor and electronics such as the instrument panel.
  7. Vibration testing machine. The parts get vibrated for extended periods. This shaking is meant to simulate the vibrations the scooter experiences in different road conditions.
  8. Impact resistance testing using a hammer weight that hits the scooter to see that the motor and frame hold when experiencing sudden shocks.
  9. Comprehensive testing machine for the assembled prototype: Real road driving simulations. Up and downhill, acceleration, wind resistance and coefficiency, and so on.
  10. Fatigue testing for prototypes before hitting production. Once a working prototype is ready the whole scooter gets tested with a bumpy ride, rotation, weighted stress machine. The motors rotate more than 300 000 times.

Those are the main tests done for the scooter before and after it gets assembled. Other tests not mentioned here are battery, rubber tire, and some other part tests done by us and suppliers.

After all these tests we can stand proudly behind our products. Thanks to this comprehensive testing our riders get to enjoy the premium ride that Langfeite escooters offer.

If you want to see what the testing machines look like take a look at our factory introduction video that also introduces our services and company in general.

Electric Scooter Suspension Explained

Electric Scooter Suspension Explained

Electric Scooter Suspension Explained

Langfeite C1 electric scooters rear spring suspension
Langfeite C1’s rear spring suspension

When thinking of electric scooters some people might have the idea that they don’t have or barely have one. This might be due to the cheap escooters and kids scooters that dominate the market but just a level higher you will find out that escooters are available with many kinds of high-quality suspension techniques. Let’s take a look at why we need suspension and what types of suspension are the main ones for escooters.

Why do electric scooters need suspension?

Simple, to ease the shocks and bumps from the surface you are riding on. This is important to keep the ride comfortable so that you won’t need a spine replacement after you hit your first speed bump and also so that the wheels maintain the connection to the road – once your wheel isn’t touching the road you have no control of the scooter.

Suspension is especially important to escooters as they are lightweight vehicles that can hit high speeds. The faster you go the more you need a good suspension. High speeds and lightweight means that without proper control of the scooter you could get to an accident if you don’t have a good suspension to make sure you have good traction at all times.

Main parts of suspension:

  • Spring and Coils: Takes on the bumps by compressing and then stretches out pressing the wheel down on the ground. 
  • Shock absorber: Often seen inside the Spring/Coil as it is the shock’s job to keep the spring and coil in place and direct the suspension in the right direction.
  • Preload – Keeps suspension at the top of its travel. For example, when you lift the scooter up you can see that the wheel is pressed to its max outward position.
  • Limiter straps – Dampens the effects of shocks

Put these four parts together and you have yourself o a good suspension. There are many ways to get these jobs done. For escooters, it’s likely to see one of the following.

Common E-Scooter shock types

  • Spring Suspension

The most common solution for escooter suspension. Has good shock-absorbing capabilities, easy to manufacture and maintain. As mentioned the Spring will compress on shock and then stretch out to keep the wheel against the road.

  • Hydraulic Suspension

One of the best ways of suspension. The shock is absorbed by a liquid-containing actuator. As you hit a bump the liquid inside gets expanded by the actuator which then “pushes” everything around it away. As they use liquid the reaction speed is basically instantaneous the result is a responsive and comfortable suspension.

  • Rubber Suspension

As simple as it sounds it’s just rubber that takes the hit. As rubber is naturally dense it’s easy to use it to reduce the noise of moving parts and general vibrations of escooters. It’s a popular choice for a cheaper escooter as it’s cheap and it’s basically maintenance-free, light, and malleable. Weight is another consideration as rubber energy storing (meaning absorbs shocks easier) capabilities by mass are much better than strings have.

Langfeite’s Suspension

Be it whichever type of escooter you wish Langfeite got you covered. We can design and manufacture escooters with all types of suspensions according to your needs. Contact Langfeite today and let’s work together bringing the world good and smooth rides!

Electric Scooters to replace taxis?

Electric Scooters to replace taxis?

Electric Scooters to replace taxis?

Will Langfeite C2 be your future transport?

We have already written about how electric scooters are the way of the future and in the previous blog, it’s the bikes that were under the threat of getting replaced by electric scooters due to their convenience to park and charge. This time it’s … taxis?

Recently Bolt a ridesharing and scooter operator company in Europe tested promoting switching to electric scooters for shorter trips in their ridesharing app. The result in short was that as many as 60% opted for ditching the taxi and switching to an escooter.

This is a very promising result as a large part of taxi rides are for short distances under 5 kilometers. If all those riders would be replaced by electric scooters the resulting CO2 and environmental impact would be huge.

The magic of escooters is that they can be personal transport methods and give you the same freedom of movement as cars can give but the limited distance they can cover is one of the key issues when people consider all their transport needs.

Typically taxis are used for medium and short distances by themselves and not combined with other transportation methods unless it is a long-distance trip to the next city for example. Considering the results of Bolt’s results many of these medium and especially short-distance trips could be replaced by escooters completely.

The future case for transport then could be a mix of personal/shared scooters used in combination with metro’s and buses to reach mid-long distance destinations and the only car traffic would be from a few taxis, delivery trucks, and shared cars for those who need the larger carry and load capacity of a car.

Tesla’s visionary CEO Elon Musk has already said that in the future if you buy a car you can choose to use it just for yourself, rent it through the app full time or part-time. Who knows, in the future a family of four could have just electric scooters, wake up in the morning and hail a shared autonomous car to the city, load the scooters in the trunk and everyone gets off at the same place once they have reached the city and continue with their personal escooters. Perhaps come back in the evening individually using escooter + metro combo.

This kind of situation is completely plausible as many people living in cities with good public transport already opt not to own a car due to expensive parking, fees, and the inconvenience of being stuck in the traffic while metro, bikes, and scoots fly on by.

Combined with the climate change goals, public opinion, and rapidly developing technology we might see this kind of tomorrow come earlier than expected.

Want to get ready for the transport of tomorrow? Contact Langfeite today and let’s ride to the future together.

Electric Scooters to replace bikes in cities?

Private E-Scooters are about to hit the streets of London

Electric Scooters to replace bikes in cities?

Electric Scooters to replace bikes in cities?

Cycling Industry recently did an interview that brought out an interesting point currently happening in our cities that haven’t implemented proper electric scooter laws and guidelines. Shops sometimes away disappoint people who can’t buy an escooter because of the regulations or the lack of them.

But why people aren’t turning to bicycles if they wish to switch to an environmentally and more fun way of commuting? Well, it’s an unfortunate side of city living – theft. Most people have had it happen to them or at least they know people who have suffered from bike theft no matter how well they are locked or even if they are stored in locked but shared bike garages that you find in many modern apartments and offices buildings. Some people opt to take the bike with them into their apartments but this normally means that you need to carry the bike or try to fit in an elevator which often isn’t possible especially if you live in one of those charming old buildings with small and narrow elevators. Once you do get your bike up it takes space in your apartment and can be in the way.

Finding a place to park your bike safely is even worse once you get to work. Public bike parking areas are often riddled with theft and bringing your bike to a crammed work elevator and the office isn’t exactly appealing.

Langfeite C2 and C3 are excellent models for both city and suburb commuting.

These are the reason why people are turning their heads to electric scooters as they have a similar nice riding experience and they are easy to bring with you in the elevator and fold away even at the workplace where you can often even charge it.

The only thing standing in the way for some cities, especially in Europe are unclear regulations but those are finally developing as more pilot programs get completed and regulators have collected enough data about the usage of scooters.

We are sure that the cities especially big ones like London will pay special attention to this method of commute as they and many others have air quality and congestion targets they want to meet.

So as they say, the demand is there so the market will answer. Do you want to be in the frontline of the electric scooter revolution? If so, don’t hesitate and contact Langfeite today!
