When examining the rim, spokes, and hubs of an e-bike, there are several crucial steps to follow. Firstly, you'll want to check if the rim is true by looking for any movement when spinning the wheel. Additionally, it's recommended to utilize the V-Brake as a helpful reference, although using your thumb or palm is also effective.
Next, pay attention to the tension of the different spokes. Are they evenly tightened or are some spokes loose while others are overly tight? This evaluation can be done by hand, ensuring that there are no excessively tight or loose spokes for optimal wheel performance.
Moving on to the braking surface, you can feel it with your fingers or utilize a calliper to determine if the rim is even and straight. This step will provide valuable insights into the condition of the braking surface.
Finally, inspect the bearings in the hub. Hold the bike and gently rock the wheel from side to side to detect any movement, which could indicate play in the bearings. Additionally, spinning the wheel will give you an idea of bearing cleanliness based on how long it spins. Don't forget to listen for any unusual noises, which may be caused by dirt between the bearings or bearings that are clean but dry.
When it comes to removing the wheel of an e-bike equipped with quick release, it is crucial to consider the type of brakes present.
For disc brakes, start by unthreading the bolts at the axle or simply open the quick-release. To use the quick-release, open the right lever and turn the nut 2.5 times to remove the wheel.
For V-Brakes or any other type of calliper brakes, it is essential to open them to free the tire for removal. Remember to close the brakes after putting the wheel back on the bike.

With these steps, you will be able to remove the rear wheel of an e-bike equipped with a derailleur clutch efficiently.
Note: Always exercise caution and consult the manufacturer's instructions before attempting any maintenance or repair tasks.
Step 1: Valve Removal
- Start by removing the valve cap.
- Unscrew the nut securing the valve to the rim.
- Take off any extra protection and release the air from the tire.
Step 2: Accessing the Inner Tube
- Use appropriate tire levers instead of spoons or metal screwdrivers to prevent damage.
- The original tire levers are recommended for their effectiveness and safety.
- If necessary, use a longer lever for tight tire removal, although this is rarely required.
- Typically, two smaller levers are sufficient. One side of the tire lever should scoop up the bead while avoiding the inner tube. The other side usually features a hook for the spokes.
Step 3: Removing the Bead
- Position the hook of the tire lever and hold it securely.
- Use both hands to gently remove the bead around the valve area.
- To remove the inner tube, start at the opposite side and carefully pull it out.
- Remember a few crucial steps to prevent a flat or unbalanced tire:
- Slightly inflate the inner tube to restore its shape.
Step 4: Tire Alignment and Inner Tube Installation
- Determine the desired direction for your tire's rotation, especially for directional tires. Once we know in what direction our tire should go and we can put one bead of the tire into the rim.
- Also, align any relevant graphics on the tire with the valve position for future reference is a good idea.
- Insert the inner tube, ensuring the valve is perfectly straight.
Step 5: Tire Reassembly
- Put one bead of the tire back into the rim.
- Apply slight pressure to the valve while inflating the tire.
- Align the tire evenly along the entire length of the bead.
- Finally, refer to the recommended air pressure range and inflate the tire accordingly.
Remember to follow these steps carefully to safely remove an e-bike's tire and replace the inner tube.
Regular inspection of air pressure is crucial for multiple reasons. Firstly, it significantly impacts safety, traction, speed, efficiency, puncture resistance, and overall comfort. By maintaining optimal air pressure, you enhance both your riding experience and the lifespan of your tires.
Determining the ideal air pressure for your mountain bike and road bike can vary based on different factors. These factors include your weight, tire size, wheel size, and the type of terrain you plan to ride through. Generally, the following guidelines apply:
Two basic rules:
For mountain bikes with inner tubes, aim for around 3 bars (approximately).
For road bikes with inner tubes, aim for around 7 bars (approximately).
To verify whether your air pressure is appropriate, you can perform a quick test. Find an obstacle and apply pressure to the wheel of your bike using the weight of your body against this obstacle. If you can easily push the wheel throughout the entire motion, feeling the edge of the rim stop against the obstacle, then the air pressure is too low. Riding with insufficient air pressure increases the risk of pinch flats or damage to your tire, inner tube, or rim. Stay safe and maintain the recommended air pressure to ensure optimal performance during your rides.
The hubs - Cleaning, greasing, assembly
The process of cleaning, greasing, and assembling your e-bike's hubs is essential for maintaining optimal performance.
Followings are the steps:
1. Start on the non-drive (left) side of the bike. Gently remove the cap from the axle, ensuring a proper grip. Determine the appropriate wrench to use for this task.
2. Set aside the bolts one by one, keeping track of their order for reassembly. Take care to gather all the loose balls and place them in a safe spot.
3. Begin the cleaning process using at least two separate cloths. One cloth should be designated for dirty components, while the other should be clean. Carefully clean each part, placing them on a clean cloth or table to avoid any debris or sand particles.
4. Once the cleaning is complete, it's time to reassemble the hub. Start by greasing the bearing on the drive side, using grease specifically designed for bearings. Apply enough grease for the balls to stick securely.
5. Install the axle, ensuring a proper fit. Repeat the same process on the other side of the hub, following the same steps for greasing and installation.
6. Ensure there is no play or movement in the hub.
Truing the wheel requires following some basic principles to fix minor problems. When the rim is shifting to one side, increasing the tension on the spoke on the opposite side will help pull the rim back into place. Simultaneously, this action will decrease the tension on the same side.
When it comes to maintaining and fine-tuning your E-bike's rear derailleur, there are a few key steps to follow.
1. Understanding Limiting Screws:
The first step is to familiarize yourself with the limiting screws. These screws control the movement range of your derailleur. Make sure to identify which screw corresponds to the highest gear and which one corresponds to the lowest gear. On some derailleurs, you may find the symbols H and L corresponding to these screws.
2. Adjusting the H Screw:
To adjust the highest gear, you will need to thread the H (high) screw. This will inwardly move the derailleur, allowing for smoother shifting to lower gears. Ensure that the derailleur doesn't go beyond the frame and the cassette during this adjustment.
3. Adjusting the L Screw:
If you are experiencing difficulty shifting from the second gear to the first gear, it's time to adjust the lowest gear. To do this, unthread the L (low) screw. If the chain tends to slip between the cassette and the spokes, thread the L screw in slightly to prevent this.
Advice:
After completing the adjustments and mounting the cable, it's a good idea to fine-tune the gear shifting. Ensure that changing gears from the lowest to the highest is smooth, while also preventing the chain from going beyond the highest gear.
4. Fastening the Cable and Adjusting Tension:
Before fastening the cable, check your barrel adjusters. These adjusters can be located at the shifter or rear derailleur, or both. Set them(as the picture showed) to the zero position and unthread them by two turns. This will allow you to adjust the cable tension from both sides, increasing or decreasing it as needed.
5. Secure the cable on the derailleur side, and adjust the tension by pulling the cable slightly and fastening the bolt in place. Remember, unthreading the barrel adjuster increases the cable tension, making it easier for the derailleur to shift from higher to lower gears. Conversely, threading it in decreases cable tension, aiding smooth shifting from lower to higher gears.
Final Adjustments:
6. To complete the process, make sure to adjust the upper pulley of the rear derailleur and the cassette. Unthreading the bolt lowers the distance between the pulley and the cassette, while threading it increases this distance.
How to adjust and what should be the distance?
When it comes to the derailleur capacity of an e-bike, understanding its importance is key. In simple terms, the capacity refers to the distance between the two pulleys or the length of the derailleur cage. This cage can be categorized as short, medium, or long. The capacity of the front derailleur is primarily focused on shaping its plates. This allows the derailleur to smoothly transition between different chainrings, including double or triple setups.
To unravel the need for different capacities, let's examine the rear derailleur cage and observe what happens while shifting gears.
The cage of the derailleur plays a crucial role in maintaining chain tension. As the chain moves through smaller sprockets, it covers a shorter distance, requiring the cage to adjust accordingly. On the other hand, shifting onto bigger chainrings and rear sprockets makes the chain travel a longer distance, necessitating further adjustments from the derailleur cage.
If the rear derailleur has a low capacity, it means fitting a short cage instead of a long one. Consequently, the chain becomes extremely tight and may even get stuck on the largest rear sprocket. Matching the capacity with the entire range of gears in the drivetrain is crucial to avoid such issues.
On the other hand, having a rear derailleur with excessive capacity doesn't pose any functional problems. Although it results in a longer chain and a slightly heavier derailleur, it can still maintain chain tension. Therefore, the key concern lies in avoiding a capacity that is too low.
The maximum capacity of the front derailleur is not tied to chain length or tension. Instead, it focuses on the shaping of plates, enabling the derailleur to effectively handle double or triple chainring setups.
To determine the necessary derailleur capacities for your specific drivetrain, follow these steps:
40-22=18
By understanding and matching the derailleur capacities to your drivetrain, you can ensure optimal performance and smooth shifting on your e-bike.
To begin the process of removing the cassette, the first step is to remove the quick release. This requires a few tools. One of these tools is a special tool that fits the lock ring on the cassette. Another tool that is needed is a wrench, which can be used to hold the lock ring while unthreading it. Alternatively, a dedicated tool with a center can be purchased to simplify this task.
There is one challenge that may arise during the process. As the lock ring is being unthreaded, the cassette will also begin to turn. To safely address this, another tool called a chain whip is required. Using the chain whip ensures that the task can be completed safely and effectively. It is important not to attempt to hold the cassette with bare hands, as it can be sharp and potentially cause harm.
It is worth noting that there is an exception for Shimano and SRAM cassettes. The SRAM cassette, specifically, will have only ten teeth on the smallest sprocket. This type of cassette requires a special freehub body called XD.
One common question often arises regarding the chain replacement on a bike. Does one replace the chain when it starts slipping through some of the sprockets on the cassette? The answer is a resounding no, as that would indicate an extremely deteriorated condition, necessitating the replacement of numerous drivetrain components.
To address this concern, a useful tool called the Chain Wear Indicator comes into play. Checking whether the other arm can fit in between the rollers of the chain determines the condition — if it cannot fit, the chain is in very good condition.
However, in emergency situations where a Chain Wear Indicator is not available, pulling the chain away from the chainrings on the crankset can offer insight. If it moves very little, it indicates that the chain is in excellent condition.
Removing and installing a bicycle chain involves specific steps that need to be followed carefully for smooth operation and optimal performance.
- Identify the link that appears different from the rest of the chain.
- Detach it first from the chainring.
- Squeeze the links against each other.
- Take note of the direction in which the chain will move during pedalling.
(Alternative: Consider using a suitable device for this step)
- Use a dedicated tool called a chain tool or chain breaker to proceed.
Installing a New Chain:
- Determine if the new chain is directional (looking different on both sides).
- Adjust the chain to the appropriate length.
- Identify the desired pin for extraction.
- Utilize the chain breaker for this task.
- Note: Extracted pins must not be reused.
- Consult the manufacturer's manual for proper guidance.
- Connect the chain using the guide pin as instructed in the manual.
- Employ the same tool used for removal during installation.
- After installation, check if the chain is functioning correctly.
Determining the ideal chain length for your e-bike is crucial in ensuring optimal performance and longevity. Here are a few pointers to help guide you:
If the chain seems excessively long, follow these steps:
- Shift the chain down to the smallest sprocket in the rear and, if applicable, on the front gears as well.
- Ensure that the derailleur applies adequate tension to the chain.
- Verify that the chain runs straight from the bottom pulley to the chainring, without touching any other parts of the derailleur.
If the chain appears too short, perform these steps:
- Shift the chain to the largest sprocket.
- Observe the rear derailleur cage.
- If the cage still has room for movement and there is a noticeable band on the top pulley, this indicates a suitable chain length.
Tools Needed:
15mm wrench: This wrench will be used to loosen and tighten the pedal's axle nut.
Before you start, ensure that you have the proper tool at hand and a suitable workspace. Here is a step-by-step guide on how to remove the pedals:
Once you have successfully removed the pedals from your e-bike, it's time to install them back on. Follow these steps carefully:
Make sure the pedal is tightened securely but avoid overtightening, as this could damage the threads or the crank arm. Repeat the process for the other pedal.

]]>Whether you're a novice rider wanting some extra guidance or an experienced cyclist needing a brush up on best practices, this guide will help keep your ebike battery running in peak condition. Read on for useful tips and tricks that can extend the life of your ebiking adventures!
Cold temperatures pose an obstacle for all electronics. It can easily cause damage to our e-bike battery. But how? The ions of the lithium-ion battery move in a viscous electrolyte. With decreasing temperatures, the electrolyte becomes even more viscous. This increases resistance for the ions, which means the ions have difficulty penetrating the electrolyte. This ultimately results in the battery supplying less energy than it does at normal temperatures. Here come the tips:
Take the battery with you into the warmth, keep it at room temperature and only insert it just before you want to set off. Our ebike’s battery is kind of like a cup of coffee in the morning. It gives our ebike the jolt it needs to wake up and perform at its best, you don't want your battery to be too hot or too cold. Cold temperatures both drain our batteries and cause the engine to require more power to get started. It’s best to charge your Eahora battery in a temperature-controlled environment, preferably indoors, between 32 °F – 104 °F (0 °C – 40 °C).
Over time, dirt, debris, and corrosion can accumulate on our ebike’s battery, which can be big trouble if it gets into the cells. Cleaning your battery periodically with a combination of baking soda and water on a damp brush will effectively remove any corrosion without damaging the battery terminals. Be sure to completely remove any baking soda when you are done as it can cause further corrosion.
When charging, the outside temperature must be right for the power stores to charge correctly. Do not run the battery completely empty. Before you store your ebike for the long term, charge the battery to a 75%-80% range. Check on it every month to make sure the percentage of the battery's energy doesn't drop under 75%. This will help you to extend the battery's life.
Riding an Eahora ebike in light rain or malfunctioning weather will do no harm to your bike, as all our ebikes are built to the IPX65 water-resistant standards. Although it is fine to ride in the rain, it's important to take preventative measures such as drying contacts on the battery and using the electrical contact cleaner. Extreme weather conditions may call for additional protection like terminal grease or avoiding immersion of your ebike and its battery – this includes pressurized washers which can cause damage.
To ensure optimal ebike battery performance, regularly inspect the electrical contacts between your battery and controller.
