Take your bike for a short test ride to assess the motor's performance, pedal-assist functionality, and overall system integration. Pay attention to any unusual noises, vibrations, or issues that might require further adjustment.

The TSDZ2, on the other hand, is torque-sensitive, so it detects how much pressure is put on the pedals and delivers more power the harder you pedal. The TSDZ2 delivers the power more smoothly, so I never feel the need to adjust the levels. The second I reduce pressure on the pedals, the motor slows down. The TSDZ2 has 4 levels. I usually leave mine on 3 and just forget about it.For people in Europe, part of the appeal is that Tong Sheng actually makes a street-legal 250W drive using the same body, so this tiny 750W motor looks legal. Did I mention that it’s tiny? I’ve seen coffee cups that were larger (and daddy likes his coffee). To find out the current chainline, measure the distance between the middle of the seat tube (it's also the middle of the bike) to the chainring's teeth. Whereas the TSDZ2 uses a torque sensor, the Bafang uses a cadence sensor, giving the motor an 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. Pros and Cons Pros

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. 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. The TSDZ2 is “torque-sensing”– if you pedal gently, you get a gentle assist; if you pedal hard, the motor works harder. This differs from the other common mid-drive kit (Bafang) which is cadence sensing – you set the assistance you want, and so long as the pedals are turning, the motor gives that flat level of assist. 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

Conclusion

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. If you are annoyed by a speed-sensing ebike with it’s “delayed power on, and delayed off”, the time interval can be adjusted, but…like most people, I am not concerned about it. My favorite ebike has a 1500W BBSHD. It takes a 1/4 turn of the pedals to start power (or I can start with the hand-throttle), and after I stop pedaling, it takes a second for power to stop.
