2. Warranty, service and support.
How long is the warranty period?
For the whole of the EU it is a two-year guarantee. And outside the EU, one year.
What does "Reconditioned" product mean?
Sometimes we receive bikes from the factory with minor cosmetic defects or that are missing non-essential components or that were used as a demo bike for a short time. In either case, these are bikes that we cannot sell as "new". These bicycles undergo a full inspection to ensure that they function as intended. We offer a shorter warranty period for their "Reconditioned" status and adjust the price accordingly.
Can I drive my #BKSlider in the rain?
It will depend on the article. Please consult the technical data sheet of each product and if you have any questions please contact us.
All BKSlides e-bike models are partially waterproof but it is impossible for them to be completely waterproof. As with any electrical device, use extra caution if you are at risk of getting parts such as the controller or battery wet as this may cause problems with the performance of your e-bike and/or void your warranty.
DO NOT LEAVE ANY BIKE OUTSIDE IN THE RAIN OR EXPOSED TO SUNLIGHT FOR LONG PERIODS OF TIME.
How does my e-bike arrive?
The assembly and first adjustment of your BKSlides e-bike does not require any special skills, just a set of tools that comes in the box with your e-bike. If you are not sure how to assemble your e-bike, you should have it assembled and adjusted by a specialised shop.
Below we show you how our e-bikes are shipped:

Why is it advisable to carry out a tune-up of my new e-bike straight out of the box?
Although we perform a pre-delivery inspection on all bikes we ship, a tune-up is advisable. This will ensure that all necessary components are lubricated correctly, that everything is tight and will enhance your overall experience.
Proper maintenance is important to ensure optimum performance and safe riding. Regularly lubricate the chain, derailleur, sprocket and all moving parts. Always check the condition of your e-bike before use and make sure it is well maintained. Cables, spokes and chain may stretch after an initial break-in period of 80-160 km, and bolted connections may loosen. A check is recommended after the initial break-in period of 80-160 km.
It is very important to have adequate air pressure in the tyres. Never underinflate or overinflate tyres. Underinflation can cause loss of control; overinflated tyres can burst. Always inflate your tyres with a regulated air source and an available pressure gauge. The suggested pressure is printed on the sidewall of the tyre.
Before changing a tyre or tube, make sure all air pressure has been removed from the tube before removing the tyre from the rim. Failure to remove all air pressure from the tube could result in serious injury.
If you do not have the experience, skill or tools necessary to service or adjust your bicycle, it is recommended that you consult a professional.
Any local bike shop will be able to carry out regular servicing and maintenance of your BKSlides e-bike.
We only use the best electric motors in the industry. Our motors are extremely reliable and 100% maintenance free. We only use BAFANG, MAC and QS motors, all brushless.
What regular maintenance is required?
Apart from keeping the battery charged, maintenance of a BKSlides e-bike is the same as for any standard bike. Once you've taken the bike out of the box and taken it for a short test ride, you'll want to do a basic tune-up. This is standard procedure for all new bikes.
Bike maintenance is a broad topic, so in this article we'll start with the basics: a pre-ride inspection, securing bolts, and cleaning and lubricating key components.
Also, don't overlook regular maintenance by a bike mechanic. If you ride regularly, take your bike in for a tune-up twice a year to ensure that complex and difficult-to-assess components such as spokes, bearing surfaces, derailleurs and cables are regularly inspected and serviced. These bicycle parts should always be checked and adjusted by experienced mechanics.
Inspection of the bicycle.
The best defence against loose components is a routine inspection before every ride. This will help you detect potential problems before they become safety hazards. Most pre-ride inspection adjustments can be made with a simple bicycle multi-tool.
The ABC: Air, brakes and chain.
Before every ride, be sure to check the "ABC" to make your ride safer and help your bike last longer.
A for Air.
Properly inflated tyres help prevent punctures. Check the recommended pressure on the side of the tyre. While you're checking the air, take the opportunity to make sure the quick-release levers and thru axles (if fitted) are also tight. Then, before you head out on your ride, make sure you have your patch kit and pump with you..
B for brakes.
Tighten the front and rear brake levers to ensure that the brakes engage correctly and smoothly.
C for Chain.
Look at your chain and all the gears. Keeping the chain lubricated and everything clean will make the bike shift more easily and the drivetrain (consisting of the front chainrings, rear cassette, rear derailleur and chain) last longer.
Securing the bicycle bolts.
Bicycles are held together by dozens of nuts and bolts. Maintaining a "tight ship" is important because loose (or improperly tightened) bicycle parts can cause severe wear, cause poor performance and create a safety hazard. Over-tightening can lead to component damage or failure.
Cleaning and lubrication of the bicycle.
It is important to carry out a regular maintenance schedule (monthly, weekly or more often, depending on your type of riding). If you spend a lot of time riding in wet and muddy conditions, or if you ride hard, fast and often, plan to clean your bike more frequently.
Keeping bike parts clean and well lubricated is crucial to good performance. Lubrication protects moving parts from excessive wear caused by friction, prevents them from "freezing" and helps keep rust and corrosion at bay.
However, be careful. Excessive lubrication can lead to poor performance and component damage (excess lubricant will attract dirt and other abrasive particles). As a general rule, excess lubricant should always be carefully wiped off before riding.
Advice: When lubricating several parts at the same time, remember the order in which lubricants are applied. If excess lubricant is wiped off in the same order, the lubricants will have time to absorb.
The following recommendations enable most cleaning and lubrication tasks to be carried out:
Clean rags: Have many of them at hand for tasks related to grease, oil, wax, cleaning and drying in general.
Brushes: Have various sizes and shapes to get into hard-to-reach places and remove dirt that rinsing alone cannot achieve. Old toothbrushes work very well.
Water: When used carefully, water can be a very useful tool. But water, especially if it comes out of a high pressure hose, can damage the sensitive electrical systems of the entire e-bike.
Soap / general cleaner:to Clean the frame, use diluted dishwashing soap or a pre-formulated bicycle cleaner.
Degreaser: A bicycle-specific degreaser (avoid paraffin or turpentine) will clean rubberised parts such as the bicycle chain. Choose a solvent that will not harm the environment (or you). Dispose of all solvents properly.
Chain lubricant: Proper chain lubrication helps to prolong the life of the transmission. Always apply bicycle specific lubricating oil to a clean chain.
There are two types of lubricant: wet or dry. Wet lubricant is most suitable when driving in wet conditions. It adheres strongly to the transmission and is less likely to rinse off in the rain. However, dirt and sand will also adhere to it, so be sure to wipe off excess lubricant.
Dry lubricant is best in a dry environment. Dirt and grit adhere less to dry lubricant, but dry lubricant rinses off easily if you find yourself driving in the rain.
What to clean and how?
Most dirty bicycle components can be cleaned by carefully wiping with a damp (or dry) cloth. Other components require occasional brushing, scrubbing and relubrication.
The drivetrain (front chainrings, rear cassette, rear derailleur and chain) deserves the most frequent attention.
The chain: The chain is the part of the bike that needs to be lubricated the most. Clean and lubricate it frequently to reduce the rate of chain wear.
To clean chains that do not have too much dirt accumulated, simply use a rag and degreaser. For heavily soiled chains, you can use a chain cleaning device, which is more thorough and much less messy.
Once the degreaser has dried, slowly apply drops of lubricant to the chain, putting a little on each link. Allow the lubricant to dry and then wipe off the excess lubricant so that it does not attract more dirt.
In general, lubricate your chain whenever it squeaks or seems "dry". Lubricating after wet rides will help prevent the chain from rusting.
Front chainrings and rear cassette: scrub the surfaces with a brush and degreaser while turning the pedals. If there is a lot of dirt build-up, use rags to wipe off any remaining dirt and "floss" between the gears.
Brake and derailleur levers: apply a drop or two of lubricant to the lever pivots and barrel adjusters periodically to keep them working properly.
Brake and derailleur cables: check them frequently (especially in wet conditions) and relubricate them from time to time so that they can effectively transfer their commands to the component groups.
Brake and derailleur assemblies: these are made up of a series of small moving parts. Keep an eye on their arms, wheels and pulleys so that they do not jam or become stiff. Apply lubricant to the pivot points.

One of the easiest items to install on a bike are the pedals, however, they can also be the most difficult if you don't know about reverse threading. Here is a great video to explain how to install pedals on your new bike.
Modification of the maximum speed limit for bicycles
It is totally forbidden and any change of these parameters means the loss of the warranty.
Before each ride it is necessary to inspect your e-bike to ensure that there are no loose fixings or accessories. If you are unsure how to carry out a complete check of the condition of your e-bike before each ride, you should consult a local shop.
Be sure to specifically check that both the front and rear axles are secure. Make sure that all hardware is secure and that all approved accessories are properly attached to your e-bike. Check that the handlebars, handlebar stem and seat post are correctly attached, aligned and adjusted to the rider.
Tyres and wheels
Es necesario comprobar la presión de los neumáticos de ambas ruedas antes de circular para asegurarse de que están inflados a la presión recomendada. Se recomienda encarecidamente al ciclista que compruebe la presión sugerida, que está impresa en el lateral de la pared del neumático. Los neumáticos sin la presión de aire correcta pueden reducir el rendimiento, aumentar el desgaste de los neumáticos y los componentes y hacer que la conducción de la bicicleta sea insegura. Compruebe que los neumáticos y las cámaras de aire están en buen estado y asegúrese de que no hay daños visibles. Si observa algún pinchazo, corte o daño en los neumáticos o la cámara de aire, debe sustituirlos.
It is necessary to check the tyre pressure of both wheels before riding to ensure that they are inflated to the recommended pressure. The rider is strongly advised to check the suggested pressure, which is printed on the sidewall of the tyre. Tyres without the correct air pressure can reduce performance, increase tyre and component wear and make riding unsafe. Check that tyres and tubes are in good condition and make sure there is no visible damage. If you notice any punctures, cuts or damage to tyres or tubes, they should be replaced.
Check the brake pads for wear and make sure they are not too worn and that they are correctly positioned in relation to the rims. Make sure that the brake cables are lubricated, correctly adjusted and show no obvious wear.
Pull on the brake levers to ensure that the brakes are undamaged and operate accurately. When fully tightening the brake levers, make sure that neither the front nor the rear brake levers touch the handlebars. If you find a problem, take your bike to a local shop for inspection.
Wheels should always turn in a straight line. If they wobble from side to side or up and down, or if the wheels become out of adjustment or the spokes become loose, they should be repaired. Do not attempt to straighten or tighten unless you have the proper knowledge, tools and experience. It is recommended that you go to a bicycle shop for service.
Crank chain and pedals
Make sure that the chain is clean, greased and runs smoothly, that the pedals are tight to the cranks, and that the cranks are tight and not bent.
Engine and throttle drive assembly
Check that all power cables leading to the engine are secure and undamaged, and ensure that the engine runs smoothly and that the engine bearings are in good working order.
Check that connectors are fully seated and free of debris and ensure that all cables and cable housing are free from damage. Make sure that the headlights, tail lights and brake lights are working properly.
Battery and battery charger
The battery MUST be securely attached to the battery holder on the frame before use and ensure that the battery is working properly. It is recommended that the battery charger be unplugged from the power socket and stored in a safe place before riding.
3. General FAQ's
Why haven't I heard of BKSlides e-bikes before?
If you have asked yourself this question then read on.
We are a small web based company selling small quantities of high quality electric bikes that we sell at factory direct prices. We don't have the huge marketing budget that a high volume discount brand has, and we refuse to dilute our brand in order to crowdfund.
We don't aim to be the biggest seller, we aim to provide a quality service at a good price.
We are not looking to be the biggest, just the best! We are passionate about our brand and we are dedicated to offering the best value for money products on the market.
Do BKSlides electric bikes have a throttle?
In Europe, we are NOT lucky enough to have the luxury of throttles on our e-bikes (EPAC), which are allowed in other parts of the world. For other uses (SpeedBike, ...) the use of throttles is allowed.
Throttles provide full power on demand and we love them because they give us full control. They are especially useful for starting from a dead stop (sometimes it can be awkward to gain momentum), getting a quick burst of power to climb a hill or safely get through an intersection.
What is Intelligent Pedal Assist (iPAS)??
Smart Pedal Assist automatically starts the motor when you pedal. With pedal assist there is no need to use a throttle to control the motor.
The integrated speed sensor uses a series of magnets in the crank, which turns the motor on when you start pedalling and turns it off when you stop. It works more or less like a switch. You have to control the boost level and speed by manually adjusting the assist mode up and down using the control on the LCD screen. This is the most common type of iPAS.
How can I contact BKSlides?
We have several ways for you to contact us:
Send us an email to [email protected]. We respond to all emails within 24 hours.
On any of the social networks we are present on Facebook or Instagram.
Or fill in the contact form and one of our online support staff will contact you within 24 hours.
4. Rules and regulations
Are these e-bikes and electric scooters street legal?
It depends on your jurisdiction, please check your local laws. But in general terms within the European Union the regulations state that with a continuous motor power of less than 250W, and at speeds of less than 25 km/h, you do not need a licence or insurance to use an electric bicycle on public roads. You can also continue to use cycle paths or any place where a normal bicycle is allowed. It is up to the consumer to find out about the legal situation in their own city and/or state/province.
General ebike regulations in the EU:
- Power of 250W.
- Motor assistance restricted to 25km/h maximum
- The e-bike must be equipped with a system that shuts off the motor when braking.
- The motor must be switched off when the operator stops pedalling or applies the brakes.
- The pedals must be capable of operating the e-bike when the motor is not engaged.
Do I need a licence to operate a BKSlikdes bicycle/electric scooter??
Consult the technical data sheet of the product. If it is within the legal parameters of the country, no licence or insurance is required, but this may vary depending on which area or municipality. PLEASE always check your local regulations.
Do I need insurance?
The vehicle registration certificate and civil liability insurance are not compulsory in mainly all EU for EPACs, but they are for other models that fall outside this category. PLEASE always check your local regulations. Be sure to check with your local authorities..
5. Questions about the battery
How to charge the battery correctly?
Never charge the battery with chargers other than the original charger you have received.
The charger will display a red light indicating that the battery is charging and, when fully charged, the light will change to green.
The charger will automatically stop charging once the battery reaches full capacity. However, it is recommended that the charger be removed from the battery within one hour of the battery being fully charged. DO NOT CHARGE THE BATTERY FOR MORE THAN 8 HOURS. Leaving the charger connected to the battery and power supply may cause unnecessary damage to the charging components.
If you do not wish to use the battery for a period of time (more than a few days) keep it charged to 70% to 75% capacity. The battery will discharge slowly over time, so check the battery charge level about once a month. When the battery reaches 20%, charge it again to 70%.
The amount of time you need to charge your battery may increase with battery age and usage. In a well-maintained situation, the average battery life is 800/1000 charge cycles. Over time and with use, the battery performance may decrease and will reduce its range of kilometres per charge.
If there are any problems during charging, please stop charging and contact us.
- Keep the battery in a dry space, away from sources of heat or flame and out of direct sunlight.
- Do not store the battery in hot or humid places.
- Store and use the charger in a safe place, away from children and where it cannot be damaged by dropping or impact.
- Before starting each charge, you must check that the charger, charger cables and battery are not damaged.
- Charge the battery only in dry rooms and where the temperature is between 10-25°C (50° F - 77°F).
- Charge the battery on a non-flammable surface and with a smoke/fire detector.
- Do not charge the battery in a damp and wet place or anywhere exposed to strong sunlight and make sure there is no dirt or debris nearby when using the charger.
- Never charge the battery with any charger other than the original one you have received.
- Do not leave the charger plugged in when the battery is fully charged.
- Stop charging the battery if you notice any damage, extreme heat, leakage, odour, smoke or discolouration.
- The charger should be on a hard, flat surface in an open space because air circulation causes the charger to cool down. Avoid covering the charger when it is plugged in or charging. The indicator lights should be facing upwards. Do not use with the charger upside down as this may impede cooling and shorten the charger's life.
- Avoid immersing the battery in any type of liquid.
- Avoid touching the terminals on the back of the battery and keep them clean of debris.
- When plugging and unplugging from the wall, always grasp the charger by the plug and not by the cord.
IT IS VERY IMPORTANT TO TAKE CARE WHEN USING AND CHARGING THE BATTERY. LITHIUM-ION BATTERIES CAN BE DANGEROUS. FAILURE TO FOLLOW PROPER CHARGING PROCEDURES, GUIDELINES AND SAFETY INFORMATION MAY RESULT IN DAMAGE TO THE BATTERY, CHARGER AND OTHER PERSONAL PROPERTY, SERIOUS INJURY OR DEATH.
What is the lifespan of a battery?
All our batteries use the latest generation of lithium cells from Samsung or Panasonic. Your battery can last for several years or approximately 1000 charge cycles. Even after 1000 charge cycles, its charge capacity can still be 75%. A charge cycle is defined as one full discharge + one full charge. If your battery is half empty and you recharge it, it is considered half a cycle. So, as you can see, 1000 charge cycles is a LOT!
Lithium batteries don't usually stop working altogether, they just gradually lose their capacity over time.
To prolong the life of your battery, we recommend that you avoid discharging it completely and make sure you charge it at least once every two months. When not in use, we advise you to store it indoors at room temperature, as extreme temperature fluctuations will damage the battery.
How far can I travel on a single charge?
We are often asked this question. The answer is quite complicated and cannot be summed up in a single figure. Some manufacturers publish very "ideal" range figures, so it is difficult to compare the range of one e-bike to another. Publishing the actual range number may not seem impressive and could hurt sales, however, our aim is to give a true picture of the battery range of our e-bikes.
The short answer to this question is pretty far! We don't hear many stories of people running out of battery.
That said, this can be a tricky question because there is no "standard" and everyone makes very different claims about range. There are several factors in answering this question. The weight of the rider, wind conditions, tyre inflation, use of the throttle vs. iPAS, etc.
Our e-bikes cover between 50 and 100 km per charge.
Does the battery charge as you pedal?
This is one of the most frequently asked technical questions we receive and shows that the advantages and capabilities of electric motors are widely known. The general answer is NO.
Recharging from pedalling is not really the intention of electric propulsion as it is, for example, in a hybrid car. In general, with an e-bike a certain amount of energy is extracted from the battery pack to assist propulsion. This energy is then replenished when charging, rather than pedalling harder during use.
With the use of our long-life batteries there is no need for "regeneration" on our bikes. The more you pedal, the further the battery will take you.
How much does it cost to replace a battery?
For the first 2 years or 1000 cycles, you don't have to worry about your battery(1). However, when the time comes to replace your battery, you will want to know how much it will cost you. Our battery replacement programme ranges from €300 to €600.
(1)Remember that the battery must be maintained, failure to do so may result in the loss of the warranty.
How to make sense of the voltage reading?
Some of our e-bike and scooter models come equipped with a voltage reading. The voltage reading is an accurate reading of the amount of energy left in your battery. For example, on a 48v battery, when the voltage meter reads less than 43V, you will notice an extreme loss of power and possibly even stop riding as the battery is very low and needs to be recharged.
Here is a table of what that number actually means for a 48V system:
V = Voltage reading
% = Charge remaining in the battery
It is very important to take care of the most expensive component of your electric bicycle. We only use the latest lithium technology. Currently, we use Samsung and Panasonic cells in all our e-bike models. Our batteries have a capacity of 1000 charge cycles, which should last between 2 and 4 years depending on usage.
What is considered a full charge cycle? If you use 50% of your battery on a trip, and then charge it back to 100% after the trip, that would be half a cycle. So a full charge cycle would be using 100%, and then charging it back up to 100%.
LOCK YOUR BATTERY IN THE ADAPTER! If you have a model with a locking function, USE IT! Failure to lock the battery into your adapter can result in serious damage to the battery.
Here are some tips for battery care: Video
