Will an Electric Bike Charge as You Pedal?
Do electric bikes charge when you pedal? This is a question many people ask when they go shopping for an e-bike.
After all, some manufacturers promote their products as having this ability, and the thought that one’s hard pedaling won’t be in vain is a good incentive to invest in a battery-powered bike!
The thing is, there is quite a lot to consider when answering this question, so in this post we will try to answer this question!
The short answer is Yes, although it’s only possible in a few e-bikes models that manage to recharge through a process known as regenerative braking. Electric bikes with regenerative capabilities will only recharge the battery on average with 10%. Recharge only occurs when you brake lightly as you go downhill or braking when approaching stop lights!
What is Regenerative Braking?
On a typical traditional braking system when the brakes are applied, friction is created to slow down or stop the bike. The action between the surface of the road and the surface of the tire creates friction, which generates kinetic energy.
Under normal circumstances this energy is usually wasted by being released into the air in the form of heat. Regenerative braking harnesses the kinetic energy and converts it into electrical energy before feeding it back into the main battery.
When either the front or rear brake levers are squeezed a signal is sent to the motor controller, quickly converting some of the momentum of the bike into electricity to charge the battery.
Regenerative braking uses the motor to slow you down, your motor can flip into a “reverse mode”. During this, the forward motion of your bike transfers friction and heat into the drivetrain, which is utilized by reverse mode. This action generates electricity which is fed back into the battery pack which increases your efficiency.
This added battery charge extends your riding range!
Hooking Up the E-bike to the Solar Panel
To generate adequate power to charge the e-bike’s battery, the solar panels you choose need to come with a decent wattage output. Ideally, you should look for an option with a cost that is less than a dollar per watt! For instance, a 100-watt solar panel for under 100 is a good deal.
You may find a cheaper panel with a small rating but when you calculate the dollar per watt, you will realize that it’s not that cheap after all. For example, a 10-watt panel for 25 is not cheap since it implies 2.5 per watt.
To cut the long story short, get a solar panel larger than 60-watt for under a dollar per watt!
Can you Fully Recharge Your Battery by Pedaling?
Theoretically speaking, it is possible to fully recharge your e-bike’s battery by just pedaling and keeping on the brakes lightly. However, this can be quite a tall order in practice because of the inefficiency of the process. For you to achieve this, it might take an entire day of riding!
Most electric bike batteries can take about six to eight hours to charge through standard charging methods, but you’d have to maintain a speed of about 15 MPH for eight to twelve hours to receive a full battery from pedaling alone.
For a person cycling continuously for several hours, the added resistance from slightly engaging the brakes will burn too much calories. What you’re doing, in this case, is converting the mechanical energy from your leg muscles into chemical energy stored in the battery.
Overall, it is just too much work to fully recharge your battery by pedaling!
Does Regenerative Braking Damage the Brakes on Your E-bike?
No, it doesn’t! On the contrary, the brakes should last longer if you use a regenerative system. Ordinary brakes are not designed to cope with intense use. Manufacturers use them because you can typically control your momentum and speed on a standard bike relatively easily.
Things get even trickier when you add a motor into the mix and reach speeds of 30 to 35mph. That is why bike manufacturers make regenerative brakes with extra power. Hence, your brakes wear down as much as you engage them.
If you commute on a quiet path daily and only need to brake upon reaching your destination, then you are not putting too much strain on the system. However, if you have to commute your way through a busy and crowded street that requires constant braking, then your brakes will wear down much faster.
How Much Can You Charge an E-bike Battery By Pedaling?
This will depend on a range of factors; from the amount of effort you put into pedaling and the time spent to the age of the battery in question. On average, the life expectancy of an e-bike battery is 5 years. After this, you should consider replacing the battery.
As the battery approaches the 5-year mark, it gets harder for it to sustain the charge properly. Even when you try to recharge it to full capacity, it will take some time.
Regenerative charging is a great way of reducing the carbon footprint and could be a great alternative to traditional electric charging. However, you can also use it to prolong the length of your ride. Depending on the settings on your bike, your speed, and the consistency of your pedaling, it is possible to fully charge the battery.
But it’s not as easy as it sounds! This is because ordinarily, it will take you around 6 to 8 hours to completely charge an e-bike battery using the standard charging method. If you decide to charge the battery by pedaling, as mentioned above, you will have to maintain the ride at 15mph for 8 to 12 consecutive hours to charge the battery.
This is practically impossible for an ordinary rider, and will still be a daunting task for a professional cyclist. Charging by pedaling comes in handy when you decide to complement it with standard electrical charging.
Assuming your commute takes one hour and you are pedaling your e-bike to get there, it should give you around 10 to 15% of the battery capacity just during transit.
This reduces the time to electrically charge the battery by the same percentage, which means less time on the charging cable!
How Effective is Regenerative Braking on an E-bike?
The effectiveness of regenerative braking on an e-bike may vary significantly depending on several factors, including the riding conditions, size of the rider, nature of the terrain, etc. The riding conditions can have a major impact on the effectiveness of regenerative braking.
If you are riding on a busy road with many stops, this will require constant braking that enables you to recapture more energy than you would on a relatively clear road. Additionally, if you are going uphill, you won’t generally use your brakes. This limits the opportunity to generate electricity.
Another aspect that can affect regenerative braking is variations in motor torque. Normally, riders tend to vary the amount of braking. For instance, people usually press the brake levers harder when they want to stop than when they are trying to slow down.
This torque variation results in inefficiencies because the regenerative braking considers the variations in torque when calculating the amount of energy to recover.
Does an E-bike Battery Charge When Riding in Throttle Mode?
Throttle mode is when you ride your e-bike without having to pedal. All the work in propelling you and the bike forward is generated by the motor, so you don’t need to pedal. Unlike pedaling, throttle mode does not charge your battery since you can’t recycle the energy output this way.
During pedaling, your legs create kinetic energy that can be converted into electrical energy and fed back into the electric bike battery. This is not possible when your legs are idle; what happens when you’re riding on throttle mode.
What are the Benefits of Regenerative Braking?
One benefit of regenerative braking is that brakes last longer since the motor is used to slow down the bike. This means the brake pads are used less, thus less wear and tear. Compared to a standard e-bike, the brake pads on a regenerative electric bike last much longer!
This will come in handy on a cargo electric bike. The engine braking provided while carrying a heavy load down a steep slope will save your bike’s brake pads from the wear and tear, in addition to providing a slight return in battery energy.
Another great thing about regenerative braking is that it helps to extend the range of the battery. The energy recouped during the process ensures that you get to spend some extra minutes on your e-bike, although it’s not much!
Challenges with Regenerative Braking
One issue with regenerative braking is that it is not best suited for two-wheel-drive braking systems. When regenerative braking is used, a negative torque is normally applied to the drive wheel. The torque is only applied to one wheel while the other one remains spinning freely.
Since braking is applied on both wheels, you will notice uneven wear and tear on the tires caused by the negative torque distribution. Unfortunately, this can easily result in skidding when you brake. No wonder many electric bikes with a regenerative braking system are designed with a rear hub motor as opposed to a front hub motor.
This is because a front hub motor would be much more dangerous for the rider during braking!
Furthermore, trying to pedal continually to make the most of regenerative braking means you will be using too much energy. It will take you a whole day to fully charge the battery, and this will take away from the “comfort” of electric biking.
The 10% power return you get from regenerative braking means you would have to pedal for 10 continuous miles to recoup 1-mile worth of energy. For this reason, you’d be better placed charging your bike’s battery by plugging it into a wall socket.
After all, most e-bikes will take around 6 hours to fully recharge, at the cost of just about 20 cents. It’s not like your savings are taking a major hit!
Are there Electric Bikes that are Specifically Built to Use Solar Power?
Currently you won’t find any major manufacturers selling off the shelf e-bikes that integrate solar power capacity. This is somewhat a shame, considering that it would offer a much easier and convenient option of charging your battery.
Nevertheless, several specialized bike models are still in development, so we can expect these to make an entry into the market as the demand for solar bikes grows. One company that is leading the journey to officially launch these types of bikes is Sun-E Bikes.
The manufacturer has produced bike prototypes with photovoltaic cells lined along the frame and wheels. These enable the bike to charge even as you ride. We’ll have to wait a little longer to see what will be available in the market though!
From the post above, it is possible to charge your battery through regenerative braking, which should earn you a few extra minutes when you’re out enjoying a cruise.
On the downside, the process is not as efficient as you may like. You only recover 10% of the charge, which is not really an alternative to standard electrical charging. Furthermore, it’s only the premium e-bike models that come with a regenerative braking system!
How to Charge an E-Bike for Maximum Battery Life
From safe charging to the longest possible lifespan, here’s everything you need to know about your electric bike’s power source.
If you bought a bike in the last couple years, chances are good it’s an e-bike. Electric bicycles are the fastest-growing type of bike in the U.S. today; in 2021 they surpassed road bikes as the third biggest category of bikes overall and in 2022 e-bike sales were over 800 million. E-bikes still outsell electric cars, and for good reason. The lightweight electric motor on an e-bike gives a powerful boost to all kinds of riding, especially utility cycling like commuting and errands. (Plus, there is a nice tax incentive for some e-bike riders.)
At the heart of that system is a powerful lithium-based battery. Taking proper care of that battery and knowing how to properly charge it is key to safely getting the best range and long-term battery life. Here’s what you need to know about charging your e-bike battery.
Safe charging basics
You should charge your battery inside, on the proper charger, and with the motor system powered off, says Kunal Kapoor, senior manager for quality and compliance at Bosch, a leading supplier of e-bike motor systems. While e-bike motors, batteries, and wiring are weather-resistant, “chargers aren’t intended for outdoor use,” he notes.
Using the proper charger is primarily a safety issue. With a modern lithium battery, Kapoor continues, when the battery signals it’s ready to accept a charge, “the battery monitoring system in the charger makes sure that the temperatures inside the battery are optimum to receive the charge,” and shuts off if needed. An off-brand charger—even rated to the same output—doesn’t have all the features of that battery management system, so current can flow to the battery even if temperatures rise, which is a fire risk.
The risk of battery fires is low, but Kapoor recommends people not leave batteries unattended while charging. You can leave the battery on the bike to charge or take it off, as long as it’s not sitting on or near flammable stuff (like the spare gas can in the garage, for example). If you’re looking at lower-priced e-bikes with house-brand or unbranded motor and battery systems, make sure the battery and charger carry a UL 2849 certification stamp from Underwriters Laboratories. This is the industry-wide standard for safe electric systems and battery charging for e-bikes. Some bike shops won’t work on e-bikes with motor and battery systems that lack this stamp, citing fire risk when left overnight in the store.
How to optimize battery range and lifespan
Let’s start with some definitions. Range is essentially runtime: how long a battery will last on a single charge, expressed in miles of riding. Range, even on the same bike, will vary; a flat commute to the office with just a light backpack will see better range than a fully loaded uphill ride home from Costco. Most e-bikes today get between 25-75 miles of range, depending on these factors.
Lifespan is how many times a battery can be discharged and recharged before it starts to lose significant capacity. When capacity starts to dip, you won’t notice less power while riding, but you will see range start to shrink. A common lifespan benchmark for e-bike batteries is 500 “full” discharge/re-charge cycles (if you use half the battery capacity and recharge, that’s half a cycle), which works out to about three to five years of normal use before capacity begins to drop noticeably.
Even though battery range and lifespan aren’t the same thing, they are linked, and actions that reduce range will also, over time, shorten lifespan. A big culprit, Kapoor says, is running the motor hard, like leaving it in Boost or Turbo mode all the time, which means a ride of a given distance relies progressively more on motor power than at lower assist levels. You’ll run the battery through charging cycles more quickly, which will shorten its life.
A less-obvious factor that strains motors and batteries is pedal cadence. Most e-bike motors are optimized for efficiency around a 70-90 rpm pedaling cadence. You can lower efficiency by pedaling too fast (Bosch motors, for instance, max out at 100-120 rpm depending on the system). common is sub-optimal efficiency from pedaling too slowly in a large gear. This is the same as “lugging the engine” in a car; whether gas or electric, the motor works harder. “Choose your gears wisely,” says Kapoor, to stay in that 70-90 rpm sweet spot.
Mistakes that kill your battery
When you buy a new e-bike, you should charge the battery to full before riding it because it’s likely been inactive for a while. But lithium batteries do not have “memory;” that is, they do not need to be fully discharged and fully recharged every time to hold their full capacity. In fact, it’s best if you don’t run a battery to zero, says Kapoor. “If you let the battery deplete completely, that may permanently damage it,” he says, and it will never recharge to its full original capacity.
If you’ll go a few weeks or more without riding the bike, store it (or at least the battery) in a dry, room-temperature space with the battery between 30-60 percent of full charge, says Kapoor. That’s the most stable level for long-term storage, and will lower the chance of a deep discharge that would damage your battery. Don’t leave your battery plugged in to the charger for long periods. It’s not necessary, and can create a short discharge/recharge cycle that will eventually reduce capacity. If you go long periods without riding the bike, check the battery charge monthly and partly recharge when it drops below 30 percent.
Lithium batteries are less affected by cold weather than other types of battery and you shouldn’t see reduced range while riding unless the temperatures are truly arctic. But researchers at the Department of Energy recently found storing lithium batteries below freezing for longer periods can damage part of the battery’s cathode, which will reduce its capacity. Lithium batteries also won’t charge effectively in cold temperatures. If you store your bike outside or in an unheated space and live in an area with sub-freezing temps, says Kapoor, bring the battery inside when not in use.
Also, keep your battery protected from extreme heat, like sitting next to a sunny window or a hot car. Excess heat can raise battery temperature enough to damage its components; in an extreme situation, it can contribute to what’s called thermal runaway, where a battery enters an unstable, uncontrollable self-heating state that can result in fire.
You don’t need to recharge after every ride. Topping off your battery sounds Smart, but over time it will reduce capacity more quickly. If you get 50 miles of range from a charge and ride 10 miles a day, you only need to recharge every three to four days.
When it’s time to replace
Even if you take great care of a battery, over time it will lose capacity. You’ll notice this on your bike’s range estimate on the controller unit. Capacity is a primary indicator of the health of a battery, so if you notice your range dropping to 70 percent or less of what it was when your bike was new, that’s a sign to start planning a replacement. If your battery is less than two years old and is well under original capacity, it might be a warranty claim (terms vary by manufacturer).
If it’s not a warranty issue, the decision on when to replace is personal preference, says Kapoor. “If you got 50 miles (of range) out of the battery originally and let’s say now you get 40, I wouldn’t classify it as ‘end of life’ if you can live with that 40-mile range,” he says. A battery with reduced capacity should still be safe, Kapoor adds.
Always purchase a name-brand replacement for your battery. Just as batteries and chargers should be paired, batteries and motors are designed to work together. And, says Kapoor, never try to repair a damaged battery or let someone else do it. Despite guides that claim you can, this is not just corporate greed or legal butt-covering by manufacturers. While e-bike batteries are almost always made from standard 18650 cells that are widely used in various products (even electric cars), those cells have a variety of different chemistries, capacities, and amperages, and that’s before we even get into connecting a string of them and repackaging the battery in the housing. The slightest mistake in any of that increases fire risk. If you need a new battery, just buy one.
Dealers that sell your brand of bike can order you a direct replacement for that bike or motor brand. Costs vary depending on battery size and brand, but plan on spending 400-800 for a new unit.
A dealer can also recycle your old one. A new program from Call 2 Recycle offers free e-bike battery recycling (paid for by bike and motor brands) through partner shops in almost every major city and many smaller ones. No participating dealers near you? Request an easy DIY shipping kit online.
Why recycle? Even a spent battery contains raw materials that can be re-made into fresh ones, at moderately less energy cost and less environmental damage than producing from virgin materials. Spent lithium batteries also have a fire risk in landfills and can leach toxic metals and other chemicals into the soil and air.
In case of fire
Though rare, battery fires do happen. If your battery gets hot to the touch while charging, unplug the charger from the wall immediately. If you can, put the battery in a metal container like a bucket (better yet, one filled with sand) away from anything flammable.
But if it’s not safe to handle, call 911 right away and tell the dispatcher that you have a lithium battery fire, which requires different firefighting methods than conventional fires. Don’t pour water on a battery fire; water and lithium react to produce hydrogen, which is highly flammable. A standard fire extinguisher may help, but in the event of a fire, special tools may be needed.
Patent Patrol: Shimano to Charge Components While Riding via Magnetic Resonance?
Will Shimano’s next-generation Di2 componentry re-charge wirelessly during riding? The brand’s latest patent titled “Bicycle Component, Non-Contact Charging System and Non-Contact Charging Method”, suggests it is not outside the realms of possibility.
US Patent 20230021733 A1 describes a non-contact charging system for bicycle components that is able to use electromagnetic induction or magnetic resonance to wirelessly charge an electronic dropper seatpost, suspension adjuster, lamp, and a front derailleur.
It spells out a situation wherein an eBike’s main battery (referred to as the non-contact charging device), housed within the downtube, is able to wirelessly charge the batteries of the aforementioned electronic components during riding. The implications of that? First off, your top-end full suspension eMTB with its electronically adjustable suspension damping, electronic dropper seat post, and even its integrated lights, could be recharged wirelessly, such that you’d only ever need to remember to recharge a single battery. And, there are plenty more benefits to be had from such a system…
As usual, when reached for comment, Shimano stated, “Shimano is constantly in development of new products but does not comment on rumors, innuendo, or speculation about products whether they are in development or not.” In the meantime, here’s an overview of what can be gathered from the patent.

Shimano’s Non-Contact Charging System for Bike Components
The only components that Shimano’s latest patent excludes is a rear derailleur and the eBike motor itself. Shimano does have a patent on a self-charging rear derailleur (EP2535257 A1), though. So, being self-sufficient, it wouldn’t necessitate the non-contact charging system described herein.
I digress. This latest patent, published 26th January 2023, depicts the implementation of the wireless charging system on both a road bike and a full suspension mountain bike but recognizes potential use on any bicycle, such as a cargo bike, gravel bike, commuter bike, and so on. For the road bike, a front derailleur and lamp are mentioned as the electronic devices that could be charged in a non-contact manner. On the mountain bike, the list of components that stand to benefit also includes a lamp, in addition to an electronic dropper seat post, and an electronically adjustable suspension (fork and shock).
Let’s take the electronic suspension adjustment (Fig. 6) as an example.
We previously covered Shimano’s patent on an electronic suspension control module with the ability to adjust the suspension stroke. That same technology is alluded to in this latest patent, but it goes further to suggest the module would also be able to adjust the softness/firmness of the suspension. That may well refer to the damping characteristics, or indeed the sag. Whatever may come of it, the point here is that the suspension adjustment module is one of the components described as chargeable in a non-contact manner, i.e., wirelessly.
In Fig. 6, you can see a telescopic suspension fork with a rechargeable battery unit (102) coupled to an electric actuator or electric motor (100a). Within that assembly, the Shimano patent describes a hypothetical series of “portions”, including a power receiver, a non-contact charging portion, a non-contact charging coil, a controller, a wireless communicator, an AC/DC Converter, and a rechargeable power source. This is diagrammatically illustrated in Fig. 3.
Here’s where it gets interesting.
The patent reads, “non-contact charging transmits power by electromagnetic induction using a frequency in a Band between approximately 100 kHz and 200 kHz”. Now, induction charging requires the charging device and component-to-be-charged to be in close proximity to one another. So, while there would be no direct wire connection for the actual charging, a wire would still be required to route a flow of electrons from the eBike’s main battery to the non-contact charging coil housed near the suspension adjustment module, whether it be positioned on a fork or a rear shock damper.
What are the benefits of that? Well, the rider won’t need to recharge the battery separately. However, you are actually adding wires as compared to the current crop of RockShox Flight Attendant forks, or a current electronic dropper seat post, both of which simply house a removable rechargeable battery. wires mean more internal routing to deal with, greater potential for rattle, a bigger headache for the mechanic… etc. The flip side of that is that the battery (or rechargeable power source as it is referred to) could be a lot smaller, given that its charge would be constantly replenished by the electromagnetic induction. That has the potential to make the component itself lighter.
Magnetic Resonance Non-Contact Charging of Bike Components?
Here’s where it gets way more interesting.
The patent goes on, “On the other hand, the at least non-contact charging coil can be configured to use magnetic resonance so that the non-contact charging devices can be one or two meters away from the bicycle components. When the non-contact charging coil receives electric power via magnetic resonance, the wireless communicator is used to communicate information to and from the non-contact charging devices”.
Next-level, right? In such a scenario, you could have truly-wireless recharging of your electronic components. A major benefit? Only needing to recharge one battery – the main battery of your eBike.
That said, it seems feasible this technology could be applied on a regular bike, too. After all, it’s not just eBikes that benefit from electronic dropper seat posts, suspension adjusters, integrated lights, and so on. If Shimano were to make the magnetic resonance-mediated non-contact charging method a reality, they could still apply it on a regular bike. There would still be a main battery which would be the non-contact charging device – it would simply be a lot smaller and lighter.
Where is Shimano going with this?
Toward a future of better integrated electronic components that require less input from the rider, on bikes and e-bikes that are lighter and cleverer than ever… I guess? Yes, I can hear the mechanics choking on their dinner. I do apologize, I meant you no harm. Jokes aside, it seems the potential is certainly there. The concept is kind of marvelous, but any benefits would be contingent upon equally marvelous execution.
I’ll finish up by saying that this patent is merely a description of a proposed invention. We aren’t saying that Shimano is working on this non-contact charging system right now, nor are we saying that it will ever make it to the market in the format described herein, or any other format for that matter. If we hear back from Shimano, we will update you guys right away.
Spero e100 A Self-Charging Electric Bike Which Promises To Deliver 100km Of Range
Spero e100 is a self-charging electric bike which is made by Coimbatore based Milltex engineers. The company has launched a total of 3 electric bikes.e30, e60 and e100. Whereas Spero e100 model promises to deliver more than 100km of range. But the range is not only the key point it has some more impressive features which I’m going to share with you.
Design And Build Quality:
For me, the design of the bike is quite bulky due to its battery placements. But due to its vibrant color finish, the bike will definitely grab your attention. Even you have 3 color options for the frame to choose from which include black, orange and blue.
The frame is made of mild steel which is strong enough to bear with up to 100kg load capacity. Even the bike is as not heavy as it looks, the total weight of the bike is 24.7kg only which light.
As far as motor is concerned, the company uses handcrafted made in India 250w BLDC hub motor for the bike. The maximum speed produced by the motor is only 25kmph, and it takes only 10 seconds to reach this speed. Though it has only 25kmph of speed, but during the test ride, it was reached around 27 – 28kmph on the throttle mode, and on pedal assist mode the speed can boost more than 30kmph.
Battery And Range:
The motor gets its juice from a removable massive 48v/15Ah lithium-ion battery which is mounted in the mid-frame. The battery takes only 2-3 hours of time for 0-80% of the charge and on a single charge, the bike will give you an impressive 100km of mileage. Even if you wish you can maximize the default range by 40% if you are on a pedal-assist mode. That means with the help of pedal-assist you can easily achieve about 140km of mileage and for the pedal-assist, the bike comes with 5 levels of pedal-assist for effortless riding experience.
One of the main highlighted features of this bike is its self-charging property. Yes, you heard it right, while riding this bike whenever you pedal the battery started charging automatically in the background. That means your energy never goes in vain as SPERO comes up with a regeneration feature. You can charge the bike with minimal pedaling.
Cruise Mode is a unique feature present in the SPERO. When you travel at a constant speed for 6 seconds, cruise mode takes over so that you can ride like a king without pedaling and accelerating.
Gears And Brakes:
Unlike regular electric bikes in the market, this bike comes with a unique no confusing 5-speed digital gear system that cuts the noise and the vibration to offer a smooth and hassle-free ride. Even shifting gears is as easy as playing a game on a joystick.
Brakes are the most important safety feature of any vehicle.That’s why without compromising on safety the company used disc brakes for both the wheels.
Wheels and Suspension:
SPERO bikes come with a 26 x 1.95″ wide Kenda tires and as usual double-wall alloy rims. There is a telescopic suspension at the front which ensures a smooth and quality ride. Although there is no suspension at the rear but as the seat of the bike filled with a gel-like material, so on the bumpy roads it will work like a cushioning.
Mobile phones have become an inseparable part of life. SPERO has a mobile charger to boost up your phone’s charge. Other than this the bike also comes with a bright LED headlight and a taillight. Other key accessories include: Helmet holder, Mobile holder, Pressure indicator will be provided with the bike.
Additionally, the Electric Control is toggled with the help of a Key, so that you could use the cycle either the conventional or the powered way.
Price And Availability:
On the basis of mileage, the company has launched the bike in 3 models with three different prices, which include SPERO e100, SPERO e60 and SPERO e30 whereas the base variant SPERO e30 is priced at ₹42900 and the mid-variant SPERO e60 is priced at ₹52900, while the pro one SPERO e100 is cost at ₹62900.
To buy these bikes you need to visit the company’s official website and contact them accordingly.
