The Tongsheng TSDZ2 isn’t as powerful as its Bafang counterpart. If we compare the power of the Tongsheng TSDZ2 750W motor and the Bafang BBS02 750 watt motor to each other, Bafang will definitely win. The Tongsheng mid-drive motors have a maximum torque of 80Nm, Bafang mid-drive motors have a maximum torque of 160Nm. The Bafang 750W version can really output around 1200W in practice while the Tongsheng 750W really outputs the rated 750W. So from these numbers, it can be easily seen that the Bafang mid-drives are just more powerful. Yes, the Tongsheng TSDZ2 can be programmed by the end user. Although, the process is more complicated (than with the Bafang) and requires a certain degree of technical skill. The main route used is through OpenSource software. Plus, you will need to buy an ST-Link V2which is an in-circuit debugger and programmer. The ST-Link V2 is a communication device required for reprogramming the TSDZ2 This motor is newer to the market, and has not had as much publicity as the BBS series. The main difference, is that the BBS series assist works with 'speed sensing', or merely relies on a sensor that is tripped by a series of magnets that spin around when you pedal. HOWEVER, the TSDZ2B series motors are activated by a 'smart, dual sided torque sensing mechanism', which also has multiple assist levels. This makes for a true 'SUPERHUMAN FEEL', because the torque sensor can tell how hard you are pushing, and signals through the controller to the motor to provide corresponding level of assist! This is a GREAT feeling, and usually only available on much higher end ebikes. The only problem with most higher end mid-drive torque assist ebikes, is that they are not usually over 350w, or 500w max. - UNTIL NOW! Mud guards again if commuting. Can be a pain if you do lots of muddy off-road riding as they can get jammed with mud.

Before ： The reduction shaft kit can be disassembled into nylon gear, shaft and one way needle bearing. Absolutely. I’ve already recommended it to a couple of people. In fact, I’d go so far as to say the only reasons not to go for a retrofit kit would be:In some cases, faults are caused by the way the kit has been installed or misused (eg derestricted, despite our warnings)

The Tongsheng TSDZ2 is one of the best e-bike conversion kits available, but it will not be for everyone. Installation can be challenging, and the motor may need periodic maintenance. It is an excellent option, resulting in a bike that looks and rides more like a factory-produced e-bike. However, another big opportunity with the TSDZ2 is there’s a very active open-source firmware build available. This allows you to tweak a whole range of values (and sorts the diminishing-assist-with-increasing-cadence issue I mentioned earlier), add in a walk-assist mode, and apparently makes it feel like a completely different motor (in a good way). So how will a torque-sensing system assist you? A torque-sensing system will assist with a certain amount of power that is proportional to the amount of force you exert on the pedals. If you pedal harder, you will get assisted more. If you pedal lighter, you will get assisted less. Because of this, you could say that the system will “amplify” your leg power with electric power. This amplification will result in a really natural-feeling ride experience. It will feel like you have really strong legs and you also won’t really notice that you are riding an electric bike. Ride experience I therefore can’t just give you two range numbers in your specific case for a 48V, 12Ah and 17Ah battery. My kit is the 48v 750w with a Hailong 48V 17.5ah battery. Its quite hilly where I live and I didn't want battery anxiety whilst out. I have been out on it all afternoon so this is my early impressions.

If you have an unloved bike gathering dust in your garage, it may be worth giving it a new lease of life and converting it into an electric bike. The Tongsheng TSDZ2 is a great e-bike conversion kit and offers a unique riding experience with a smooth torque-sensing pedal assist. In this review, I’ll look at the positives and negatives of this motor kit to see if it’s a viable option in 2023. Push motor BB axle into BB tube,the exxposed axle length on left side is 11mm(Put securing plate onto BB axle, Put 2 washers between motor and securing plate,Tighten the securing plate and the motor with two m5*6 screws). Water ingress – Although water resistant, I wouldn’t recommend riding in heavy rain or deep puddles.

Special speed sensors, which are more robust, and include a split 'Y' adapter, to hook up a 6V 3W headlight, and 6V 3W taillight, which you can control from the display More responsive and intuitive pedal assist feel – some say this brings the feel of the motor closer to that of the expensive Bosch system. I have tried to persuade them, but they didn’t give. They told me that if you don’t supply the original (unmodified) product, my warranty is voided. This is also includes an original battery wire. Once you establish your need for an electric bike, take time reviewing various factors for you to find a good one. Start by comparing different models while focusing on their unique features. Renting out e-bikes from your local bike shops will allow you to dig deeper into a bike's specifications to determine whether it's a good fit or not. You can also consult with friends or bicycle vendors who are familiar with motor-powered bikes.

The battery proved to be ridiculously over specced and also very heavy. I rode a 40mile circuit quite a few times and the last outing used exclusively level 4 for the last third with not even half the battery used. On my next build I will try to get a 500w bottle type battery and fit to the downpost of the seat to get the weight more away from the front, and to give it a less ebike look. If you’re reading this you are probably familiar with the Bafang mid-drive conversion kit. I really like the Bafang and have installed more of these than any other motor. Although the Tongsheng and Bafang share similarities, once you get beneath the skin the two motors are quite different. The Bafang BBS mid-drive motor is a good alternative to the TSDZ2 As said in the display section, e-brakes are only available if you choose the VLCD5 display. So if you need them, choose the VLCD5 display. I think that e-brakes are not as essential with the Tongsheng TSDZ2, since the pedal assist will almost immediately stop if you stop pedaling. But still, e-brakes will provide some added safety. If you choose not to install them, you will also have less wiring managing to do. So whether or not you will need them will depend on what you value more: convenience or a bit of added safety.

The included LCD display is a game-changer. It offers real-time data on your speed, distance, battery life, and even trip information. Its intuitive interface makes it easy to navigate through the various settings, ensuring a seamless riding experience.In terms of safety, the Tongsheng TSDZ2B boasts pedal-synchronized power output, providing an ultimate safety experience for riders. This means that the motor activates only when you pedal, reducing the risk of accidents and providing a more natural riding experience. I went out with a friend who has an expensive hiabike xduro nduro bike and we tried each others bikes and did a bit of offroading. It compared very favourable with the haibike. Maybe I'll do a more detailed review. The blue nylon reduction gear can be prone to premature wear, although this seems to hinge on how hard the bike is being ridden and is unlikely to be a problem on commuter or leisure bike. ***The newer TSDZ2 ‘B’ has a different system and Tongsheng claim to have rectified this issue. Whereas the TSDZ2 uses a torque sensor, the Bafang uses a cadence sensor giving the motor a very on/off feel. The Bafang is much quieter, almost silent. But, it’s heavier, more expensive and just as prone to technical faults. For more information, please read my Bafang vs Tongheng comparison article. What’s included in the TSDZ2 conversion kit?
