About Tongsheng

A noteworthy aspect of Tongsheng’s motor systems is their torque sensor technology, a pivotal component that distinguishes their mid-drive motors. Torque sensors measure the force applied to the pedals, allowing for a more intuitive and responsive power delivery. This not only contributes to a more natural riding experience but also maximizes energy efficiency, a critical consideration in the realm of electric mobility.

Tongsheng TSDZ2B Mid Drive Motor is the Upgraded Version of TSDZ2, and there are 48V500W and 36V250W. The reduction gear kit and the clutch inside the motor has been upgraded. The upgraded parts make the motor work more smoothly, higher efficiency,
less wear and longer service life, which brings you better riding experience.

Tongsheng TSDZ8 Mid Drive Motor is the latest version in 2024 and there is 48V750W. The power output of TSDZ8 is higher than TSDZ2B and provide you with more energy and faster speed.

Tongsheng offers a range of motor options, catering to diverse user preferences and riding conditions. From commuting to off-road adventures, their motors deliver a compelling blend of power and efficiency. Additionally, Tongsheng motors are often lauded for their quiet operation, ensuring a discreet and enjoyable riding experience.

    This is my second kit from them. I am very satisfied with the Tongsheng kits. Thanks to the torque sensor, pedaling feels natural. It's equivalent to a high-end electric bike. The seller has good prices, delivers well and quickly. He advises on purchases, responds well and quickly, and also helps after the purchase! He keeps his commitments. He is one of the few very serious and professional shops on Aliexpress. I recommend without hesitation.

    24" bike for children. I had to make some adaptations, mainly in the battery support, to make it fit securely on this 24" bike. One of the brake sensors stopped working after 5 days of use. This 250w/36v model is quite weak even for my 10-year-old son. I suggest buying a 500w or 750w model with a 48v battery. I will do OSF on the firmware to see if it improves a bit, especially in terms of speed. But overall, it's a good set that works well without too many demands. It reaches 25km/h, and the battery lasts well.

    Not yet installed, but tested. Everything works, minimalist display and that's what mattered. The motor has so many descriptions online that there's no need to write more. The battery gives a solid impression, time will tell about the quality. The product is well packaged. Very fast delivery. For now, I recommend it.

    Everything went very quickly and smoothly. He didn't have a brake lever in stock, but he sent a brake sensor instead, which unfortunately wasn't good, but he wrote in a message that if it doesn't fit, he would send brake levers too, just send him a message. He always responds to messages within 1 day. Very fair seller, i can only recommend him.
