The outer diameter of the motor body is only 79.5mm, which is very small. It can't be seen that it is a rear drive motor unless from the side. Its weight is only 1.7kg, which is only equivalent to the weight of two bottles of water and a portable combination tool, which changes the appearance of ' stupidity and coarseness' of traditional electric motor; Hidden and lightweight design must be highly praised.

 

Exquisite Display

The display is equipped with 2.2-inch LCD color screen, and the screen display effect is exquisite. Key and screen integrated side mounted, small and light. Side mounted integrated dial, gear key, on key and setting key are located on the side of the display; The key operation has clear vibration feedback, and the switching perception is obvious during riding.

 

Concealed Battery

The hidden battery design integrates the 36V 7.8ah battery with the lower pipe and is completely embedded in the body. Coupled with the unified and harmonious coating, the appearance has a high degree of integration.

It is very convenient to charge the removable battery. The battery capacity of 7.8ah is also sufficient for daily commuting. The bottom of the battery fits with the concave base of the lower pipe of the frame, and the upper end is fastened with a buckle. In addition, the key is locked, 'multiple insurance' ensures that the battery will not be loose even when driving on bumpy roads.

 

 Noiseless and Waterproof

Motor noise is the weakness of many e-bikes. Mice M070 drive system has made great efforts in the selection of motor, gearbox and materials. It adopts ultra-silent design, and the noise level is lower than 50dB. It hardly can hear the motor operation sound under outdoor riding conditions.

Riding Experience

Lightweight, Silent, Efficient and Non-resistance | MIVICE M070 Electric Drive System Review

During the test for more than one month, this bike became my daily commuter, with a fixed commute distance of 22 kilometers every day. The motor is the soul of the whole bike and the most obvious part in the test.

 

Commute

The most amazing is the smoothness of the moment when the motor starts to help. Although it is driven by the rear hub motor, the built-in torque sensor in the central shaft realizes the 'man-machine integration' riding experience with the exclusive control algorithm. After letting several colleagues test ride for a few days, I got the following feedback “Why is this bike so smooth? '“ It doesn't seem to help so much, but it's very comfortable. '“ The assistance intervention is very timely and it's easy to go uphill. '“ Where is the motor? Why there is no sound? '

Yes, 'smooth' is the first feedback of all colleagues who have tried to ride. Compared with the recently evaluated e-bikes, this one should be said to be quite smooth. Behind 'smooth' is the result of synchronous and efficient operation of high-precision torque sensor and controller.

According to the riding observation for many days, this set of motor operates is very sensitively, not only at the moment of stepping on the pedal, but also according to the torque, the motor will quickly generate a corresponding amount of power, up to 500W +. Although it has a large power auxiliary output at the moment, this power is not abrupt, nor does it have the 'push back feeling' of other grumpy motors, which is very stable.

With the start of the bike, the S300 torque sensor placed at the center axle detects in real time. Therefore, when the stepping force changes, the power assistance will also change. Timely intervention timing gives people a very comfortable feeling. In fact, the important criterion for judging whether it is smooth or not depends on the intelligent calculation and rapid response of the whole system to the human stepping action. Max power has a full set of system solutions, combined with the original control algorithm, to achieve the riding feeling, which is amazing.

It is worth mentioning that the controller 'black box' also adopts the hidden design and is placed near the torque sensor at the end of the bottom tube. Therefore, the controller can’t be seen from the appearance, so it looks more beautiful and tidier.

 

Level Road

Lightweight, Silent, Efficient and Non-resistance | MIVICE M070 Electric Drive System Review

On the level and stable road, the motor will have a slight soft help between 30W and 70W. Please don't underestimate this help. It's like the difference between ordinary road running and running on the treadmill. I believe you will fall in love with this uniform and comfortable riding feeling. The soft and stable characteristics of the drive system are very obvious, and it is really surprised to get it in the rear hub motor.

In addition, the official said that in the urban road riding environment, adults weighing 75kg can output power with 5 level pedelec, and the battery life of 7.8ah can reach 70km; In the actual test, there is still 15% of the remaining power after riding 70km, indicating that the official data are relatively conservative and true. It can be seen that its efficient system is only charged once a week after commuting.

Due to the new national standard limit of up to 25km / h, the assistance in the level road is a little 'anxious'. With a stable power output, the whole commute ride is quite light. If you use pedelec level 2 and 3 in the whole process to achieve the balance between speed and endurance, the riding experience will be better. Step gently under your feet and the wind blows your face, which is the feeling of 'I've been riding for dozens of kilometers before I make the effort'. It's very relaxed.

In fact, if the whole bike is equipped with appropriate gear ratio, the bike is easy to exceed the power assisted speed of 25km / h, so the riding feeling without pedelec is also very important.

The full set of electric drive system includes 1.7kg motor and 90g controller. The total weight is only about 2.2kg except the battery. When the drive system is turned off or 'overspeed' without power assistance, the unique motor clutch unimpeded design plays an important role. Riding is not much different from ordinary bicycles. If you ride fast, there will even be the illusion that the motor is still working, and the increased slight sense of weight will be offset.

Therefore, complying with the speed limit provisions of the new national standard does not affect the actual follow-up acceleration. I believe that if this system is transplanted to better configured road bicycle, it will have higher efficiency and faster speed.

On the premise of not damaging the original structure of the frame, install the embedded battery, shaft torque sensor and rear hub motor. This whole scheme makes it easier to refit the traditional bicycle into intelligent e-bike, which is not only more harmonious in appearance, but also more controllable in cost.

The extra motor system will not become a burden on the road. The real technology is that you can't feel the existence of technology. No wonder that colleagues say that it doesn't look like e-bikes, and it doesn't ride like e-bikes at all.

Basically, I ride 11 kilometers round trip the company at an average speed of 28 km / h. With the addition of electric power, the top speed is reduced, but the whole journey is more relaxed and comfortable, and I have more physical strength and energy to focus on work. Especially for the start and stop status of multiple traffic lights, you don't need to shift gears frequently to start and then accelerate. Just step on it gently, the motor will naturally keep up with your strength, and the commuting comfort will be greatly improved.

 

Climbing

Lightweight, Silent, Efficient and Non-resistance | MIVICE M070 Electric Drive System Review

Uphill should be the best place for pedelec to play its value. Pedelec is also considered by riders as a sharp weapon to 'weak into strong in seconds'. This pedelec bike makes climbing easier. Relaxed and comfortable written on face. It has a pleasure which traditional bicycles without. There is no doubt that this max power electric booster has excellent climbing ability. Whether you ride TCR or emonda, in front of the long and steep slope are all its 'follower'. Talk about its climbing experience in detail. As long as it is timely intervention, stable output, reasonable gear ratio and uniform trampling, there will be no sense of frustration of 'sudden drying of the motor', nor will there be a lag feeling of 'late arrival' when stepping on it. The right help is the most needed when climbing.

The climbing speed of 20 + km / h on steep slopes may only be its 'passing line', but it has almost become the 'ceiling' of your traditional bicycle. The lightweight of the whole bicycle and the strong power of the motor are the guarantee for people's confidence in climbing sections.

What's more comfortable is the durability when climbing. You can use the maximum power gear to climb a slope for several kilometers at the speed of 15 + km / h without panting and soaring heart rate. When climbing is no longer laborious, you will have more energy to enjoy pure fun during riding.

It was also used as a work bicycle for several external shooting work. Last week, it performed surprisingly during the climbing of Huolu mountain for a TCR highway bicycle. With the help of 300-500W continuously blowing out from my feet, it is no longer difficult to turn back to the steep slope continuously, and even a drop of sweat does not fall. I can easily complete the climbing shooting task back and forth for several times. It is no matter how long it is difficult to climb the steep slope. I have also changed from ' afraid to see the slope ' to today's 'climbing king', so that I have more energy to focus on shooting and creation.

This electric powered commuter is very suitable for those riders who don't want to climb 1% of the slope, and also for colleagues who don't want to ride a bike every day and sweat all over the company. The small and fresh color matching and lightweight silent design are more suitable for my little sister's daily outing. If you install this pedelec system with excellent weight control on a highly equipped road bike, it will not only sacrifice small weight, but also make you even stronger.

In fact, pedelec drive has been integrated into our life for a long time. New pedelec can be seen in city bikes, folding bikes, road bikes, mountain bikes, Cargo bikes and fat tyre bikes. How to skillfully integrate traditional bicycles and modern pedelec is a difficult problem for all e-bikes. The key to solve this problem lies in including motors, controllers, and a complete set of drive system with sensors as the core. If your one-way commuting distance exceeds 15km, you might as well try this Mivice pedelec bicycle equipped with M070 motor system, which will certainly change your inherent cognition of pedelec bicycle.
