e) The front derailer and chain rings are going and being replaced by a new single chainring (toothed ring which the chain goes on) so dont worry at all about these 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. 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?
Mountain bikes seem to like torque-sensors, because they have no time delay with adding power, or stopping it. They also like a light drive, and this kit is about as light as a 750W mid drive could be made. When it comes to service and support, Tongsheng has received commendation from users. Should you encounter any issues or have questions during the installation process or while using the kit, you can rely on their strong service and support team to assist you. d)The fewer gears in the rear cassette the better. The motor is so powerful you tend to forget to change gears and only use the higher half even on big hills 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.
Preparing for the Installation
I’ve ridden torque-sensing ebikes at Interbike, and I have to confess, I do like the feel. However, the ebike I ride the most right now is a 1500W BBSHD from Luna Cycle. When spring of 2019 arrives, my next project is boosting the BBSHD power to 2500W, so a 750W drive doesn’t interest me, no matter how smooth and seamless the power application is. 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 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.
The “Q-factor” (from Quadracepts, meaning the width of the pedal placement) on the TSDZ2 is wider than average. Some riders swap-in the BBS02 crank arms, which reduces the Q from 210mm to 182mm. Some builders swap-in only the right-side crank arm to make the pedals more evenly spaced from the centerline of the bike. Display shows more advanced information like battery voltage, rider pedal power in watts, motor temperature, cadence, trip time and distance. The TSDZ2 comes with one 42T chainring, which uses a fairly common 110-BCD mounting pattern (110mm, Bolt Center Diameter ). However, due to its’ modest power level, some builders are been very appreciative that this style is easily adaptable to using two chainrings and a derailleur.If you want an analogy, it’s a bit like the early days of smartphones with Android and Apple. If you wanted something to just work, didn’t mind Apple setting the rules on how it worked, and were willing to pay a premium; you bought an Apple phone. If, instead, you wanted something to work exactly the way you wanted it to, and didn’t mind a bit of effort to get it that way, you bought a cheaper Android handset. Units Type - mph (please note that the manual states that if using mph, on your VLCD5 display you must set the wheel size to the largest size on there - 35 in my case - I did so and it seems to work fine) The TSDZ2 has torque sensing like on many European made bikes. What that means is the motor senses how much force or torque you put on the pedals and adjusts the power correspondingly. Noise: The Tongsheng is quieter. While the BBS02 is quiet, there is still a humming sound. I can barely hear the TSDZ2. [editor: noise between the TSDZ2 and BBS02 seems to be hit or miss, due to manufacturing variations] PAS power levels are adjustable, regardless of the type. TS enthusiasts often mention that it is a more natural and intuitive cycling experience to use a TS type of PAS. The expensive factory drives from Bosch, Yamaha, and Continental use this. But those companies won’t sell it in a kit that can be added to a frame that you already own. There are only a few companies that will sell a TS kit (Lingbei, Xofo, etc), and the TSDZ2 is not only the most available, it is also the most popular.
