Regenerative Braking in Electric Bikes

Electric bikes are considered as alternative transportation for fast travel however, there is always a fear of having a short driving range. To resolve this issue, elaborate research about brake energy recovery technology or regenerative braking is available.

But what is Regenerative braking? To explain it in easy words, one can say that it is the process in which the energy from the motor is used to charge the battery while braking. Regenerative braking is common for electric vehicles, however, it is rare on electric bicycles.

 In electric bikes, the regenerative braking system contains a developed microcontroller-based control system. Regen means that the electric motor is used to slow down the rider when stopping and generating some energy. The energy is then fed back into the battery pack which ultimately increases the efficiency of the rider and range.

Regenerative braking drastically reduces the brake wear and prevents the brakes from getting hot especially while riding down the hills. Moreover, regenerative braking never squeaks and has a smooth feel. Electric bikes that have a gearless hub motor also have regenerative braking.

Further, regenerative braking in electric bikes is seamless in the riding experience. The rider will notice a gentle acceleration from the direct drive motor compared to a bike with a geared hub motor. In simple words, regenerative braking acts like a powerful dynamo when the levers are pulled.

How regenerative braking works?

Regenerative braking is an advanced and supplementary braking system. Before regenerative braking, there was friction between brake pads and brake discs. Thus, converting the vehicle’s kinetic energy into heat which is wasted and dissipated into the air. Howbeit, regenerative braking utilizes this waste energy by charging the e-bike battery.

The regenerative system works with dual functions. It acts as a motor in one direction while as a generator in the opposite direction. As a motor, it converts the kinetic energy into mechanical energy by driving the wheels. However, while braking the system acts as a generator, running in the opposite direction.

Regenerative braking captures the rider’s kinetic energy as soon as he applies the brakes. The energy is then put back into the battery to use instead of wasting it on a stop. Nearly all the energy from the battery is utilized in combating air resistance.

Since the rider weighs lesser than a car. Thereby, there is a huge amount of energy available to be captured. While cycling almost 90% of the rider’s effort and energy is exerted opposing the air. The air resists as the riders move forward. Thus, the cyclist can only go 10% further. As the rider captures all the kinetic energy while braking.

Regenerative brakes on electric bikes create extra drag, even when not using the brake. Since the motor is always engaged in an e-bike with a regen system, so the motor is always turning even when coasting. The positive effect on the efficiency of a regenerative system greatly outweighs the small negative effect created by the extra drag.

When the battery of e-bikes is full, power will not flow into the battery. This phenomenon helps in protecting the battery. It also ensures that whether regenerative braking is converting more energy to the battery than it can handle or not. Also, if the brake levers are too tight. There may be a chance that the mechanical brakes begin to stop the bike before regenerative braking has a chance to kick in.

Anyhow, regenerative is effective only up to certain speeds. It is not very efficient at lower speeds. So, it only effectively assists the regular braking. The braking duties are not entrusted to the regenerative braking alone. Also, even in ideal conditions, there will only be a 10% recharge back to the e-bike battery. This is because braking periods are short and batteries like to be charged at low currents for a long time.

Why don’t E-bikes use Regenerative Braking?

Firstly, regenerative braking requires a far more complex interconnected braking, battery, and drive system than what you typically have with a normal e-bike. The design is complex and significantly drives up the cost of manufacturing the e-bike. The cost of all the features of e-bike would get put onto the consumer until the company itself cuts down on quality in other components. The price alone is often a huge turn-off for most e-bike companies.

Secondly, regenerative braking is a much heavier braking system than a typical e-bike brake system. The added weight means that the overall performance, especially the range, is going to be impacted. While regenerative braking typically adds 10% to 15% of range back to the battery as the rider rides. The added weight will also lose 2% to 5% of the range. As a result, the overall range extension is quite small compared to the price you must pay for it.

Thirdly, regenerative braking is detrimental once the battery of the e-bike is dead. As the added weight and complex motor system, the regenerative braking system impacts how hard the rider must pedal to accelerate with your e-bike. Most e-bikes will provide a normal pedaling experience with their motor on or off, but that is not the case with regenerative braking systems.

Lastly, this braking system causes the battery of e-bikes to degrade faster. The batteries of electric bikes have a certain number of charging cycles. It varies with the type and company of the battery used. Each time the battery is charged, it loses a fraction of its total capacity. Therefore, the battery needs to be replaced after a few years. Regenerative braking causes degradation. The degradation caused by regenerative braking is far less effective than the power boost provided by a dedicated charger.

Furthermore, regenerative braking does a special job. It converts kinetic energy to electricity, but in the process of doing so will create its heat as well. Due to their proximity, the batteries will be exposed to more heat than they otherwise would be with a traditional braking system. This can also cause the battery to degrade more quickly.

It gives you, ability to walk run, and live life on your own, independently. According to a survey, approximately 10millions of Americans have osteoporosis. Osteoporosis is a very common disease, specifically among women, that causes the bones to become weak and brittle. To live a fuller life, everyone needs to maintain a balance in their lifestyle and give priority to their health.

E-bikes can help achieve this balance. Cycling is nothing less than a workout. There is not much difference between riding E-bikes and exercising on different machines in the gym. In fact, by cycling, you can make your calf, thigh, buttocks, arms, shoulder, and even the foot muscles stronger and better in shape.

Stronger muscles mean stronger bones and joints which leads to a perfect body shape and a healthy lifestyle as well. In short, E-bikes are now the future that can take care of both your time and health at the same time.

3. Obesity and weight control

Nowadays, a large number of people are dealing with serious health problems as a result of their weight gain. High blood pressure, diabetes, heart disease, strokes, clinical depression, and other diseases are all linked to obesity. People who ride an electric bike regularly, get a good workout and improve their cardiovascular health.

Cycling is proved to be boost metabolism, builds muscle, and burns fat, making it a great way to keep or lose weight. According to studies, cycling at a steady pace burns around 300 calories per hour. If you cycle twice a day, the calories burned quickly add up. As per British research, a daily half-hour E-bike ride burns nearly five kilograms of fat over the course of a year.

People are riding E-Bikes on a regular basis, which is assisting them in losing body fat and promoting weight loss. E-bike travel is also a relaxing form of exercise that can be tailored in terms of duration and intensity. You can easily increase or decrease the duration and intensity of your cycling routine, as per your need. As a result, you can ride your e-bike while getting the workout you want.

4. Boosts mental health

People nowadays of almost all ages and especially the youth, suffer a lot through depression, anxiety and so much more which causes mental illness. One of the reasons they get into a situation where they can neither think properly and nor able absorb the pressure is because of the inability of their minds to process and work accordingly.

They keep sitting in one place in front of the electronic gadgets. And even when they commute from one place to another, they do it using automobiles such as uber and other transportation services. Physical activity in such a busy world gets ignored which is so crucial for one’s health. Even for the people who really want to get started with physical exercise, the lack of stamina and confidence makes it inapplicable.

That’s where e-bikes come into play. You don’t have to ride with full strength and stamina all the time like in conventional ones.

You get to breathe in the fresh air and the blood circulates through your whole body. The body of a person itself speaks that how healthy a person is overall.

Cycling slowly and breathing in fresh air is sometimes even considered a meditation process. It helps you relax your mind and soothe your body. In short, e-cycling can give you a healthy and fresh day start and increase a person’s ability to think efficiently, take decisions wisely and live life in a very healthy manner.

5. Beginners’ confidence building

Many people, especially women, are apprehensive about riding bicycles. They are afraid of juggling cycles and find it difficult to manage cycles in difficult situations. People who have had surgery find it difficult to get out on the road with their bicycles. Riding bicycles in hilly terrain is a challenging task.

E-bikes assist riders in tackling hills and long journeys. Due to the electric motor, taking road tours on e-bikes is sweat-free and requires less effort. Cycling has become suitable for athletes who can’t get back to their routine just by riding e-bikes. E-bikes can help regain confidence for people who had stopped cycling due to age factors or fear to ride cycles.

People can get back into cycling with the comfort of knowing that they have an electric motor to assist them with any scary hills or if they simply run out of steam on the way home on an electric bike. E-bikes give people confidence, which improves their fitness and makes exercise more enjoyable.

How do electric bikes work?

With every passing day, the use of e-bikes is abruptly increasing. Nowadays, e-bikes can be seen almost everywhere, be it may the roads, cycle paths, or mountaineer tracks. This is because e-bikes are the perfect option for anyone who wants some extra power while enjoying cycling.

The things that make e-bikes a great alternative to regular bikes include the ease of the rider and the speed of an electric bike. As compared to a traditional bike, an electric bike provides effortless assistance to the rider’s pedal-power and enables them to go further with less effort, which provides it an upper hand.

There are different types of e-bikes available in the market to accommodate all kinds of riders. There are commuter bikes, full-suspension mountain bikes, foldable bikes, and many others. An e-bike is basically a bicycle with an installed electric motor.

The motor is an assistance to the rider in propelling the bike forwards. The electric motor will let you ride much like you ride a normal bicycle, but with less effort. The motors use internal gearing to balance their power output and enable the rider and onboard energy source to achieve synchronization in pedaling.

The motor works by automatically switching on the motor when you pedal. The motor senses how much power you are putting into the pedals and responds proportionally.

This makes the rider feels like having strong legs. The e-bike motor is very responsive and allows the e-bike to roll more freely without the additional drag of a motor in the hub. Brushless electric motors convert the battery’s energy to pedaling assistance, but they do spin at a much higher rotation than your riding cadence.

The key to any ideal electric bike is ensuring that all the components work together. The battery, motor, and display combination will provide all the assistance required in a smooth ride.

The battery provides power to the motor which powers the drivetrain to give the rider all the assistance to tackle hills and long adventures. The assistance provided and power sent from the motor to the drivetrain is controlled by the display.

The controller is like the ‘brain’ of an e-bike that connects all the aspects of the bicycle. It is just like an onboard computer that controls all the aspects of an e-bike. The display works like a ‘window’ to your e-bike.

With the help of a display, you can adjust the motor settings and can check the electronics. The mission is to connect all, power, motor, sensors, and make sure everything is running smoothly.

All the critical functions of the e-bike are controlled by a circuit board present inside the controller. This circuit board manages voltage and amperage input and output to control the e-bike.  An e-bike controller gains energy from the battery and supplies it to the motor accordingly. It monitors battery voltage, bike speed, motor power, pedaling activity, and more.

There are different sensors on an electric bike that play a vital role in the better performance and smooth working of the e-bike. The speed sensors immediately engage the e-bike motor once the rider begins pedaling. The torque sensor is a little smarter as it responds with a little assistance to match the rider’s speed. It is much more responsive and helps with speed and maneuvers.

Sensors perform more than a thousand calculations a second to measure your torque input, cadence, and speed. Once the e-bike’s sensors detect a need for battery-assistance, they automatically react to a master algorithm controlling the entire system. Power is released from the battery pack to energize electromagnets in the motor.

E-bikes are typically heavier than non-electric bikes and thus the added weight needs to be considered in stopping distance and safety. There is no direct impact on how hard the rider uses the brakes on e-bikes because of the power alternate to a conventional bike.

When the rider starts pedaling or while going down a hill, the spinning wheels turn the electric motor in the hub in reverse and start charging up the batteries. Since electric bikes are much lighter than cars and other vehicles thereby, they never gain or lose as much kinetic energy compared to other vehicles.

When it comes to charging, it is super simple and easy. The e-bike battery takes around 2 to 8 hours to charge just like a phone or laptop. The time usually depends on the make and model of the battery.

The battery of an e-bike can be in varying places on the bike, often dependent on the frame type and size. The lighter the frame, the lesser the weight of the bike overall. The further it can travel before the battery dies.

The total range of your e-bike will be depending on several factors. The main factor which plays a part in calculating the range of e-bike is the total capacity of the equipped battery. The competence to which you ride and care for your e-bike are also some factors that should be considered to evaluate the total range of the e-bike.

Coming to the assistance modes, E-bikes focus on both power and speed limits. To meet the standards and requirements of riders, the drive units are limited to 25 kph. Once the rider hits 25.1 kph, the electric assistance of the e-bike will rapidly decrease, and once the assistance stops, the rider can continue pedaling the bike just like a traditional bike. Similarly, coasting downhill is the same as a standard bike, the rider is free to pedal.

The electrical parts of an e-bike do not require any maintenance. Mechanical parts are way similar to that of a non-electric bike. The servicing of mechanical parts is quite easy.

It can be performed at any bike shop. Although this is not a maintenance task the rider should make sure that the battery keeps some charge in it. Otherwise, it might discharge to a point so low that you can’t charge it anymore. Thus, it will be killing the battery which is a costly mistake to make.

From these details, we can conclude that an e-bike is much more effective and efficient in its working and performance as compared to a traditional e-bike. We have provided you with the details of how these electric bikes work. Now, with all this information you can better evaluate electric bikes. Drop a comment below to let us know about your thoughts and questions on the working of e-bikes.

What You Should Know About Electric Bike Laws and the Regulations

With more people turning to apprehend that bicycles are not just invented for recreational or exercising purposes, the popularity of e-bikes is growing rapidly worldwide. Apart from providing fitness and recreational usability, the primary function of an e-bike has always been to get from one destination to another.

Considering the situation of pandemic and long commuting routes people are drawing towards electric bicycles as an alternate vehicle. The use of internal combustion engines is being restricted across various regions. It is also one of the reasons as to why people are switching to e-bikes.

In many countries around the world various legislations are being proposed that should be taken into account before purchasing an electric bicycle. While using an e-bike, it is an obligation for the rider to be informed about laws and regulations. This is important to decrease possible citations and increase safety.

Cultural paradigm and law enforcement of speed limits, along with physical infrastructure and other factors play a vital role in cycling speeds. They choose operation decisions made by the electric bikes. E-bikes are governed by the Consumer Product Safety Commission (CPSC) which is a federal agency that controls the sale and manufacture of products.

In the past, the laws in America regarding bicycles and e-bikes have been fairly neglectful. It was commonplace to see bikers riding down the sidewalk, riding either against the flow of traffic or with an umbrella in hand. Recently, American law enforcement has become sterner and more proactive regarding citations to cyclists who are not following the rules of the road.

As a cyclist in America, you must know and abide by the rules of the road that apply to any other motor vehicle. The e-bike riders are expected to obey the lane rules. The riders are not allowed to ride in pedestrian-only areas or lanes. In addition to this, the cyclists cannot ignore stop signs or stoplights and must have operable brakes on the bike.

There are some other important rules as well, that a rider must abide while cycling inside city limits.  For example, the age restriction. At present, there is no information regarding an age limit for e-bike riders in these areas. However, it is better to reach out to your local law enforcement regarding this area of concern to be on the safe side.

Electric bicycles are ideally used for off-road purposes and have no regulations. However, an e-bike that exceeds 250W in power must be classified as a motorbike and registered accordingly. Furthermore, any rider on an electric bike with a power output greater than 250W must be licensed and insured.

Every e-bike owner should know the cycling laws in their area or region. All the cyclists need to obey the same rules. If a rider is uncertain about the e-bike laws in a city or state, it’s better to contact a local law enforcement agency for clarification. Bikes allowed on some specific trails vary in the federal state.

Any enthusiastic cyclist should aware of the basic cycling road rules. The e-bike ordinances should be acquainted in the areas where the cyclist rides the most. The e-bike laws and regulations vary from state to state.  There are a few standard expectations that all cyclists are anticipated to be mindful of, regardless of what state they’re riding in.

Some regulations and definitions used for e-bikes show the vastly different terms and requirements for electric bikes. It is clear how easily confusion can arise. Firstly, there is a perceived contradiction between the federal definition. Secondly, there is a general lack of e-bike-specific definitions at the state level for most states. Lastly, there is always a dispute between how states define and govern e-bikes and how municipal governments do so within their jurisdictions.

There is a three-class system in the United States that has simplified the electric bike market. Still many states have not adopted this plan. About e-bikes has been scattered as there are no set federal regulations. The federal government allows each state or local government to establish its laws regarding electric bicycles. Anyhow, knowing the classes of e-bikes will advise that where and how can you ride your e-bike.

The legislatures of different states have begun to tussle in how to differentiate and define an electric bike. The operations and equipment standards on roads and trails have been regulated. State legislatures will resume with defining e-bikes, clarifying operation, safety, and equipment. Also, the standards and further distinguishing from motorized vehicles such as mopeds and scooters.

According to the three-tiered e-bike classification system. The class 1 e-bike is any bicycle equipped with a motor providing assistance only when the rider is pedaling. When the bike reaches the speed of 20 miles per hour, the motor ceases to assist.

The class 2 e-bike is a bicycle equipped with a motor to exclusively propel the bike. This e-bike is not capable of assisting when the bicycle reaches the speed of 20 miles per hour. The class 3 e-bike is a bicycle equipped with a motor providing assistance only when the rider is pedaling. When the bicycle reaches the speed of 28 miles per hour the motor assists.

The classification points to the different e-bikes based on specific features, including top motor assist speeds and how power is generated. Although this classification system creates a standard set of expectations. Moreover, it also protects the consumers and reduces confusion about whether or not a machine is an e-bike.

The foremost thing that these e-bike classification laws did was uplifting the speed limit for all e-bikes to 28mph. Now every Class 3 e-bike in the market has a throttle. There is a host of different e-bike manufacturers selling electric bikes with a higher 28mph speed limit along with pedal assistance. Some e-bike kits allow creating the rider’s e-bike out of any e-bike class.

As of now, only the maximum speed of an e-bike powered by a motor is specified in the law. It does not provide a maximum speed when the bicycle is being driven by a combination of human and motor power. The federal law of the US does allow e-bikes to travel faster than 20 mph when using a combination of human and motor power.

State traffic laws and vehicle codes remain the sole domain of many states and state legislatures. The manufacturing and first sale of an electric bike are regulated by the federal government. Most of the states in US also have their own laws.  

There is a categorization of e-bikes with other motorized vehicles that require licensure and registration. Sometimes they do not allow them to be used on facilities such as bike lanes or multi-purpose trails. 

Drinking or being drunk while driving a motor vehicle on public roads is undoubtedly a criminal code in the US. Under this criminal code, e-bikes are also included. Anyone riding an e-bike while being intoxicated would be charged for the impaired driving. The offender will be subject to the criminal code penalties in case of conviction. This may include a fine, driving halt, or even some jail time. 

There is no standard set of safety rules like other aspects of bike laws. Since there is no such law doesn’t mean you shouldn’t take every precaution possible. Looking into the legal requirements is a good initiative when determining which safety accessories and gear you’ll need. Helmets are considered one of the effortless and most effective ways to reduce and prevent severe head injuries.

Anyhow, if you’re hoping to purchase an electric bike that doesn’t fall within the law parameters, then reconsider your choice. The lack of universal e-bike ordinances and marketing nationwide often results in mopeds, motorcycles, and other electric riding devices being confused for e-bikes. If an e-bike has been modified to generate power that exceeds 28 mph with assistance, is no longer considered to be an e-bike. It is rather a motorized bicycle or a scooter. Let us know in comments, if you have any uncertainty regarding any e-bike law.
