ED20: Upgrade your cycling experience at a quite small cost

Unlike the traditional eBike system that uses mechanical finger shifting, Magene includes electronic shifting for the first time. ED20 can be integrated into your eBike system through wired connection and powered by the eBike battery. The performance will be more stable through a wired connection and can improve the cycling experience significantly at a very small cost.

The ED20 small-volume wire actuator solution can realize gear shifting via buttons, which can effectively reduce finger fatigue or pain and is more accurate. Moreover, the handlebar is more concise by removing the mechanical shifting. The product is small in size, easier to install and hide, and the cycling experience can be upgraded without any bike modification.

In addition, ED20 electronic shifting is also an excellent choice for users or clients who want to improve the riding experience at a low cost. Compared with a direct electronic drive, the cost of the small volume wire actuator can be reduced by 80%, greatly reducing the upgrade cost. As a separate component, the ED20 is also very convenient to disassemble and use and can be installed in any position of the eBike, or hidden in the bike frame.

Torque Sensor vs. Cadence Sensor: which is better?

On an e-Bike, the Torque Sensor or the Cadence Sensor is important in the e-bike system for improving performance and operation. Below, we will briefly compare and analyze them.

Torque Sensor

The torque sensor is a device that senses changes in the rider’s outgoing force acting on the pedals, cranks, and bottom bracket. It measures the torque or force changes generated during riding. The torque sensor senses the changes in real time and transmits the signal to the controller to adjust the motor’s output. For example, in the case of climbing a hill at a low speed, although the speed and pedaling frequency are not high, the rider will need more power to pedal, and then the motor receives the feedback from the torque sensor and will output more to assist the rider. Therefore, the torque sensor can help to provide more precise power output, thus optimizing the riding experience.

Cadence Sensor

The cadence sensor is more focused on monitoring how often the rider pedals. It can sense the rhythm and speed of the rider’s pedaling in real-time and transmit this signal to the controller. The working principle of cadence sensors is generally through physical contact, such as via metal contacts or magnetic induction, to detect the pedaling frequency. There is also some new cadence sensor that adopts non-contact design, such as through infrared or ultrasonic wave to detect the pedaling frequency. The cadence sensor is critical in speed control and mileage calculation. For example, when calculating the total mileage, it is necessary to multiply the distance and the number of times of each pedal stroke, and the number of times of each pedal stroke needs to be provided by the pedaling frequency sensor. In addition, the cadence sensor can also help control the power output at a specific pedaling frequency to adapt to different riding needs.

In summary, torque and cadence sensors are critical in adjusting the electric assist during the riding. Their main difference lies in the different physical quantities they measure: the torque sensor mainly measures the torque or force during riding. However, the cadence sensor focuses on the frequency of the rider’s pedaling. With its help, the motor’s power output will be precisely adjusted during the riding, providing a better riding experience. At the same time, their presence also makes e-Bike much more intelligent and better to meet the various needs of users.

Stay Away From e-bike Explosion And Keep Safe

e-Bikes have become a popular means of transportation in many cities recently, but more accident and injury reports show up coursed by e-bike explosions. There may be several reasons for that:

1. Lithium battery safety issues. E-bikes usually use lithium batteries as a power source, and lithium batteries are prone to explosion under overcharge, over-discharge, high temperature, and other conditions. In addition, some bad manufacturers will use low-quality lithium batteries to reduce cost but leads to battery problems.

2. Improper charging. During the charging process of e-bikes, if using an improper or unqualified charger, or placed in a charging state for a long time, the battery may overheat, resulting in an explosion.

3. Quality problems of e-bike parts. Some e-bike components may have quality problems, such as motors, controllers, chargers, etc., which may cause vehicle failure and eventually lead to an explosion.

4. Improper use. Some owners may install inappropriate parts on the bike, such as too-powerful motors, batteries, etc., which may also cause the electric bike to explode.

Therefore, to avoid the danger of electric bicycles exploding, we need to do the following:

1. When buying an e-bike, choose a well-known brand and avoid buying low-cost, low-quality products.

2. Use bike compatible charger, do not change privately. Keep in mind that following the correct charging method and requirements.

3. Avoid using e-bikes in high temperatures, high humidity, and humid environment.

4. Do not install inappropriate parts on the bicycle, such as extra batteries, overpowered motors, etc.

5. When you are on the road, follow traffic rules to avoid collisions or other dangerous situations.

In short, understanding the causes of e-bike explosions and how to avoid electric bicycle explosions is the key to our safety.

Magene e-Bike System Solution: Fat Tire Electric Bike

Fat bikes are becoming more and more popular nowadays. A fat bike (sometimes referred to as a fat tire bike) is an alternative bicycle sub-type that utilizes ‘fat’ tires, which are usually between 3.5-5″ wide, providing increased traction compared to your average bicycle. The wider tires a fat bike uses are designed to distribute the rider’s weight over a larger surface area, like sandy trails & beaches, snow, mud, swamps, bogs, and many mountain bike trails.

As the eBike has become the new hot trend, electric fat tire bikes also have become a hit in city transportation. With their unique and sturdy design, electric power, cool looks, and ability to handle rough terrain, they are quickly becoming a popular choice for urban commuters, adventure seekers, and anyone who wants to get around the city in style.

EBIKES: Rear Drive VS Mid Drive

Both rear drive and mid drive ebikes have their own advantages and disadvantages, and the choice between them ultimately depends on the specific needs and preferences of the rider. Here are some of the benefits of rear drive ebikes compared to mid drive ebikes:

Simpler design: Rear drive ebikes are simpler in design than mid drive ebikes, as they have fewer moving parts and are easier to maintain. This can make them more reliable and cost-effective in the long run.

Lower center of gravity: Rear drive ebikes have a lower center of gravity than mid drive ebikes, which can make them more stable and easier to handle, especially at higher speeds.

Quieter operation: Rear drive ebikes tend to be quieter than mid drive ebikes, as the motor is located further away from the rider’s ears.

Better for off-road riding: Rear drive ebikes are generally better for off-road riding, as they provide more torque and better traction on steep inclines and loose terrain.

However, there are also some advantages to mid drive ebikes, including:

  1. Better weight distribution: Mid drive ebikes have a more balanced weight distribution between the front and rear wheels, which can improve handling and stability.
  2. Greater efficiency: Mid drive ebikes can be more efficient than rear drive ebikes, as the motor is located at the bike’s center of gravity and can take advantage of the bike’s gears to optimize power output.
  3. More natural feel: Mid drive ebikes can provide a more natural feel when pedaling, as the motor provides power through the bike’s chain and pedals, simulating the feeling of a traditional bike.

In summary, both rear drive and mid drive ebikes have their own benefits and drawbacks, and the choice between them depends on the rider’s specific needs and preferences.
