But how do you choose between these two models? What are the major differences? In this article, we’ll compare the Bafang BBS01<\/strong> and Tongsheng TSDZ2B 250w<\/strong> motors from different angles, such as design, features and reliability. We’ll also be looking at the weight and size of the motors, as well as their speed control and pedaling assistance. Finally, we’ll give you some recommendations for choosing the best motor for your electric kit (spoiler: it’s ours, and we’ve got 10 totally objective reasons<\/a> to prove it ) according to your needs and preferences. Whether you’re a keen cyclist or an occasional user, this article will help you make an informed choice and get the most out of your electric bike.<\/p>\n The choice of motor is one of the most important<\/strong> elements in the purchase of an electric kit.<\/p>\n It determines your bike’s power<\/strong>,<\/a> speed<\/strong> and range<\/strong>. So it’s essential to understand the differences between the motors so you can choose the one that best suits your needs.<\/p>\n There are two types of motor<\/strong> for electric bikes: hub motors<\/strong> and pedal motors<\/strong>. Hub motors are placed in the front or rear wheel<\/strong> and are easier to install and maintain. Pedal motors, on the other hand, are integrated into the frame<\/strong> and offer more natural assistance<\/strong>. <\/p>\n In terms of power, pedal motors<\/strong> are generally more torquey<\/strong> and offer more effective assistance when climbing. Hub motors, on the other hand, are better suited to travel on flat terrain and with light loads. <\/p>\n Reliability<\/strong> is also an important criterion when choosing an engine. High-quality<\/strong> motors last longer and require less maintenance<\/strong>. <\/p>\n In conclusion, choosing the right motor for your electric bike is crucial to ensuring a safe and enjoyable riding experience. It’s important to consider your needs in terms of power, reliability and autonomy to make the most suitable choice. <\/p>\n Tongsheng<\/strong> and Bafang<\/strong> are two well-known Chinese brands in the world of electric bicycles that have experienced significant growth in recent years. Both brands offer quality products at competitive prices<\/strong>, making them popular with electric bike manufacturers. <\/p>\n Tongsheng<\/strong> equipment is renowned for its reliability<\/strong> and durability<\/strong>. They are also highly efficient and offer good autonomy<\/strong>. Tongsheng motors are often used on electric city and trekking bikes. <\/p>\n Bafang<\/strong>, on the other hand, stands out for the innovation<\/strong> and performance<\/strong> of its equipment. Bafang pedal motors are very powerful and can reach high speeds. They are often used on electric mountain bikes such as MTBs and Fat Bikes. <\/p>\n The BBS01<\/strong> is manufactured by the Chinese brand Bafang<\/strong>. It was introduced in 2014 and has since become one of the most popular motorizations for electric bike kits. The Bafang BBS01 motor is a central drive unit, mounted on the bottom bracket axle. It is compatible with most bicycles, provided the frame is suitable. <\/p>\n The TSDZ2<\/strong> is manufactured by the Chinese brand Tongsheng<\/strong>. It was introduced in 2018 and has become very popular among cyclists looking to convert their bikes to electric. The Tongsheng TSDZ2 is also a central drive unit, mounted on the bottom bracket axle. It is compatible with most bicycle frames, provided the frame is suitable (see here how to check compatibility<\/a>).<\/u> <\/p>\n In conclusion, both Tongsheng<\/strong> and Bafang<\/strong> offer quality<\/strong> electric bicycle motors at competitive prices.<\/strong> While Rated power and maximum power<\/strong> are two important<\/strong> terms to understand when it comes to choosing a motorization for an electric bike. Rated power<\/strong> represents the maximum power that the actuator can deliver consistently<\/strong> over an extended period, while peak power represents the maximum power<\/strong> that the actuator can deliver over a short period<\/strong>. Motors with a higher power rating are generally more powerful and offer stronger assistance, while motors with a higher peak power can provide stronger assistance when starting and climbing. <\/p>\n The impact of nominal and peak power on electric assist operation, motor durability<\/strong> and range depends on a number of factors. Firstly, motors with a higher power rating tend to heat up<\/strong> more quickly, which can shorten their service life. In addition, motorizations with higher peak power can also cause additional stress<\/strong> on components<\/strong>, which can also reduce their service life<\/strong>. <\/p>\n As far as range is<\/strong> concerned, engines with a higher<\/strong> power<\/strong> rating can consume more energy<\/strong>, which can reduce battery life. Similarly, engines with higher maximum power can also consume more energy, which can also reduce battery life. <\/p>\n The Bafang<\/strong> BBS01<\/strong> is a 250-Watt, 36V<\/strong> motor that can deliver up to 80 Nm<\/strong> of torque and 750W of maximum<\/strong> power. <\/p>\n The Tongsheng TSDZ2b<\/strong> is a 250-Watt, 36V<\/strong> motor that can deliver up to 80 Nm<\/strong> of torque and a maximum<\/strong> power of 675W<\/strong>.<\/p>\n All in all, the two engines are virtually equivalent in terms of nominal<\/strong> and peak power<\/strong>, with a slight advantage for the Bafang BBS01<\/strong> (we’re not taking into account its big brother, the BBS02 500W or 750W, or the 1000W BBSHD monster, which are obviously more powerful but banned from public roads in France and Europe<\/a>).<\/p>\n Speed, cadence and torque sensors are key elements in the operation<\/strong> of an electric bike motor. Each of these sensors has a different impact<\/strong> on battery life<\/strong>, performance<\/strong> and driving comfort. <\/p>\n The speed sensor<\/strong> measures the speed at which the bike is moving and sends this information to the motor to provide the necessary power. This sensor is used on most entry-level<\/strong> electric bikes and is considered the least accurate<\/strong> of the three. It does not take into account the effort made by the cyclist, and can therefore be less efficient in terms of battery life. <\/p>\n The cadence sensor<\/strong> measures the number of pedal revolutions<\/strong> per minute and sends this information to the motor to provide the necessary power. This sensor is more precise than the speed<\/strong> sensor and takes into account the effort made<\/strong> by the cyclist. However, it does not measure the force<\/strong> applied to the pedals, which can make the ride less smooth and enjoyable. <\/p>\n The torque sensor<\/strong> measures the force applied to the pedals and sends this information to the motor to provide the necessary power. This sensor is considered to be the most accurate of the three<\/strong>, ensuring a smooth, pleasant<\/strong> ride. It takes into account the effort made by the cyclist and enables more efficient<\/strong> use of the battery, which can increase<\/strong> range<\/strong>. <\/p>\n In terms of autonomy, the torque sensor is the most efficient<\/strong> because it allows more precise use of the battery. However, it is also the most expensive<\/strong> and is often used on high-end electric bikes<\/strong>. <\/p>\n The Bafang BBS01<\/strong> is equipped with a cadence sensor<\/strong>, which measures the rider’s pedaling speed and adjusts power accordingly. The Bafang BBS01<\/strong> is also equipped with a speed sensor<\/strong>, which monitors the bike’s speed and provides speed-dependent pedaling assistance. <\/p>\n In addition to the cadence sensor,<\/strong> the Tonsheng TSDZ2<\/strong> is equipped with FOC (Field Oriented Control)<\/strong> is an electric motor control system that enables greater efficiency<\/strong> and precision in power management<\/strong>. One of the key advantages of the FOC is that it can be used with a torque sensor<\/strong>, which measures the force applied to the crankset and automatically adjusts motor power accordingly. This makes for smoother, more natural<\/strong> driving, as well as better battery management<\/strong>. All in all, the FOC with torque sensor is an ideal choice for cyclists looking to maximize performance and comfort on their electric bikes. <\/p>\n Our Open Source Firmware<\/strong> algorithm<\/strong> (FOC) also eliminates the need for a brake sensor<\/strong>. These are compulsory on other engines, to prevent the motor from forcing while the brakes are applied. Brake sensors are therefore a necessary step on Bafang BBS01 ( and BBS02 and BBSHD), which lengthens installation time<\/strong> and can sometimes cause problems (compatibility of brake levers with the braking system).<\/p>\n The TSDZ2 has a big advantage<\/a> in this essential design point, bringing it even closer to top-of-the-range electric bike<\/strong> motors.<\/p>\n The size<\/strong> and weight<\/strong> of a central drive are key factors to consider when choosing a motor for your electric motor kit. A motor that’s too big or too heavy can affect the bike’s aesthetics and reduce ground clearance, which can be a problem when riding in town or on uneven terrain. So it’s important to choose a motor that suits the size and weight of your bike for an optimal riding experience.<\/p>\n The BBS01<\/strong> is heavier<\/strong> and bulkier<\/strong> than the TSDZ2<\/strong>. The BBS01<\/strong> weighs around 4.2 kg<\/strong> and measures 213 mm in length, 110 mm in width and 135 mm in height, while the TSDZ2<\/strong> weighs just 3.6 kg<\/strong> and measures 214 mm in length, 110 mm in width and 100 mm in height. <\/p>\n In this respect, the TSDZ2 is lighter, and both powerplants are roughly the same size with their 42T chainrings. But without their trays, it’s the TSDZ2<\/strong> that’s smaller and therefore more discreet<\/strong>. <\/p>\n![\"first](\"https:\/\/syklo.fr\/wp-content\/uploads\/2023\/04\/5399170806_48d82d5550_w.jpg\")
