Brakes: With the BBS02, I often used the e-brakes to cutoff the motor. I would often gently squeeze the brakes, even if I was still pedaling, if I’m going near traffic or pedestrians. Then I would release the brakes and the motor would re-engage. You don’t really need e-brakes with the TSDZ2. I would just pedal more lightly and the motor turns off. It’s more intuitive. In fact, I re-installed my regular brakes instead of using e-brakes (bonus: less wires). There is no fear of lurching. It’s just smoother. Most TSDZ2 kits don’t come with e-brakes or a throttle, and you don’t really need it. Before ： The reduction shaft kit can be disassembled into nylon gear, shaft and one way needle bearing. The TSDZ2 also comes in a coaster brake version. If you have a coaster brake bike, this is the only game in town. No other mid-drive or rear hub motors can work with a coaster brake. You could put a front hub motor on a coaster brake bike, but front hubs have their own issues. The TSDZ2 coaster brake motor opens up a lot of fun bikes to the possibility of an even more fun ebike.
Il faut comprendre que beaucoup d'utilisateurs de ce moteur le montent sur des VTT et l'utilisent avec un accélérateur et franchement ce moteur n'est pas fait pour ça, d’où les problèmes mécaniques. We here at ReCycles have done extensive work and research on these units, and offer an exclusive custom made model, more powerful, and with features and optional upgrades unavailable anywhere else. Remember, we love this stuff ourselves, and although we usually are into 'higher power EV'... we LOVE the torque sensing on these units, and the feeling of 'super-pedaling' that you simply cannot get on any ebike system that does not have a quality torque sensor. This one sensing torque on BOTH sides, and is quite smooth.

However, you must not fit a bigger ring than 44T. The TSDZ2 has 42T ring, maximum 95RPM. On bikes with cassette and 700C wheels, that is 30 mph. Speaking of efficiency, I do not recommend adding a hand-throttle to this kit. There is nothing wrong with a hand-throttle, but if you like that, the BBS02 has a huge global community that can help you with any issue. As mentioned previously, initial take up of drive is a touch aggressive and the assistance in the 3 higher power settings is noticeably weaker than before...but as mentioned, have yet to test again on a steep climb. Zero Start Performance] — because the torque sensor can accurately detect the foot force, and give it several times in time. It can output accurate torque signal when it is at rest, with excellent zero start performance.
If you have a mobility reduction or impairment, you should opt for the TSDZ2T which is the TSDZ2 with throttle which helps climbing hills without extra work. If you just want an off-the-shelf, buy-it-and-ride-away, no-maintenance-needed ebike. Nothing wrong with that; it’s not as if you would be asked to fit the engine to your car after buying. Kits are not the same as bikes, which are supplied as complete items needing little or no intervention by the customer. 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. Also because the pedal sensing is built into the motor unit and it is sensing the torque you put in through the pedals, it is very good at identifying when you need that assistance and blending it in smoothly. Something you don’t get with a standard pedal sensor which generally is either off or on. Value and ConclusionsAs an aside I used self-soldering heat shrink to make the connections ( heat shrink with an internal collar of solder) they worked brilliantly. Question: I've been looking at the specs and it states 250w however the controller is set to 16A and the battery is 48v. 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 TSDZ 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!
No, it’s resistant to water and can be ridden in the rain, but I would avoid puddles. Will the TSDZ2 fit bikes with thru-axles? Once you've completed the installation and fine-tuning, it's essential to conduct thorough testing to ensure everything is working correctly. Follow these steps: Conducting Initial Tests Par ailleurs, côté certification j'imagine que ce moteur a un certificat comme le Bafang BBS01. Exemplaire ici pour l'ancienne version : https://static.webshopapp.com/shops/044915/files/083778140/cocsmarttorque.pdfcoaster brake function -----it is means If you bike don't have any brake lever, you must use the motor with coaster brake function, otherwise you can choose the motor have a freewheel keep your cadence high. Output power = torque * rotational speed, the higher your cadence, the more help you get from the motor. The fixed reinforcing plate is optimized by adding embossing, depending on which the motor was better fixed even After booting up and setting off, the Speedo reads 0 mph for about a minute before bursting into life. 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).
You may also need a drill, 6.5mm drill bit if you need to install a couple of M5 rivnuts on the downtube to secure the battery cradle.How reliable is the Tongsheng TSDZ2? Below, I’ve listed the common problems associated with the Tongsheng motor. Certains revendeurs proposent des manivelles Bafang qui ont un déport moindre que celles de Tongsheng 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.
Great Deal
