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. Familiarize yourself with the installation process by carefully reading the provided instruction manual and watching online tutorials. This will give you a clear understanding of the steps involved and any potential challenges you might encounter during the installation. P.S: The links to where I bought the parts from are just that, not an advertisement and they are likely available elsewhere. 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.
I said the TSDZ2 max power was a touch low, but it still does the job. My electrified Sutra weighs 36kg, I weight about 85kg, and even carrying about five kilos of shopping it’ll still trundle up a 12% hill at 20kph-ish. Add more weight (say my four-year-old), and you’ll need to change down another gear, and will be going up the same hill at maybe 15kph. On the flat it’ll happily get you up to 25kph (where the assist fades away; again, a legislation thing). 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. With the Tongsheng, spare parts are available even to amateur mechanics, and there’s a good amount of stuff online on how to replace parts. After the upgrade of fixing plate, the adaptability of the motor is improved, so that the motor can also be installed on e-bikesNow ： The reduction gear kit is all in one which is not able to divide. Then there’s no one way needle bearing anymore. One of the most significant advantages of the Tongsheng TSDZ2B conversion kit is its ease of installation. Even if you're not a seasoned mechanic, you can install it with the help of detailed instructions provided. However, if you prefer a hands-off approach, seeking professional assistance is always an option. It’s not as good on hills as the Bafang BBS02 but is fine on moderate hills. Is the Tongsheng TSDZ2 waterproof?
This is great, you control the bike very much like a normal bike and it gives the impression that you have bionic legs. Let’s start off with the key question – is a bike with a retrofitted Tongsheng TSDZ2 motor going to be as good as a dedicated ebike? This has nothing to do with the manufacturers' power rating, if the manufacturers say 250W then that is what they expect the users to use it for on average. After canceling the one-way bearing, the new design is all in one nylon gear which can bear greater torque with Today I put a further 12 miles on it and continued to be impressed. There is now less need to change the assistance settings as often if at all if you do not mind a little effort, although getting into the swing of letting the motor take the strain, I did up the power on some steep bits. If there is one niggle it is that the motor seems a bit too keen to help now in the lowest power setting so that whereas the drop off is smoother at 15.5mph, plodding at around 8mph in places on a canal towpath for example the power could be felt taking up the drive. After another 20 miles or so I think I will hook her up to the laptop again to reduce some of the numbers to try and improve that some more.In some cases, faults are caused by the way the kit has been installed or misused (eg derestricted, despite our warnings) Plus, your bike is almost certainly going to weigh less than 36 kilos (even with the motor adding about 4kg, and call it another 3 for the battery). I have a thing for adding heavy accessories to bikes… I’ll also mentioned that Tongsheng’s firmware (ie the code that tells the motor how to behave) is a little weird. In particular, you get maximum assist at an oddly low cadence – about 60. It then tails off until at about 100 RPM you get very little help at all. This is not intuitive if you’ve mentally programmed yourself to spin up hills to stop your knees exploding; I sometimes need to change up to a harder gear if I want more help on a hill (this only works if you’re not already getting the max available power from the motor. If you are, then you need to change down to keep going. You’ll get the hang of it after a few weeks, honest). 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: La technologie des capteurs de couple a changé, il y avait des problèmes de fiabilité sur les premiers modèles
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. When installing and using the TSDZ2B Mid Motor, it's essential to prioritize safety. Here are some tips to keep in mind: Ensuring Proper Electrical Connections Display shows more advanced information like battery voltage, rider pedal power in watts, motor temperature, cadence, trip time and distance. A word of caution; if you’ve got a warranty from the place you bought the motor from, flashing a new firmware onto it would obviously void that. Plus I believe it’s possible to tweak the firmware to make the motor non-EU-legal, which would leave you riding an uninsured, un-registered motorbike (not a good situation to be in should you ever find yourself in a collision, regardless of fault). Conclusion – would I buy it again? C'est la raison pour laquelle certaines organisations aux US préconisent l'utilisation de la norme UL2849 qui certifie l'ensemble du véhicule.
Adjusting and Fine-Tuning the Installation
As an aside I used self-soldering heat shrink to make the connections ( heat shrink with an internal collar of solder) they worked brilliantly. En Europe, la situation n'est certainement pas si catastrophique et il me parait inenvisageable que les VAE disparaissent. Il faut noter que ce moteur (le TSDZ2) est moins puissant que bien des moteurs certifiés et c'est l'un des plus proche en termes de fonctionnement des moteurs homologués. Labor/Power-saving] — When climbing a hill, it is as labor-saving as starting. Flat riding is extremely energy efficient and power saving.Since the output is proportional to the output of the person, the coordination is good, and it can be said that the perfect combination of people and machines. The motor has an extra support mount – resulting in a much more reliable install than a Bafang BBS motor. Community: The Bafang products are more popular and have been widely used, tested, and customized. There are more tutorials, information, and guides by far than for the Tongsheng products.
Connection between battery and motor will require soldering. These motors are supplied with bullet connectors and our batteries are supplied with XT90 connectors, you will receive the corresponding XT90 connector with your battery. Changing the connector will NOT invalidate your warranty. The TSDZ2 is a crank drive kit meaning it applies the power direct to the spindle which the pedal arms are attached to. This is more efficient than hub (wheel) kits and is better for hills and heavy riders. As its torque based the ride is also smooth and feels more natural akin to having bionic legs.
