TONGSHENG TSDZ8 INSTALL, TEST RIDE, IMPRESSIONS.

What's up, guys! In this video, we're transforming a standard bike into a powerful, torque-sensing e-bike. I'm unboxing and doing a full installation of the Tongsheng TSDZ8 750w mid-drive motor. https://www.aliexpress.us/item/325680... This motor is a popular alternative to the Bafang BBS02, with one huge advantage: a true torque sensor that gives you that "bionic legs" feeling instead of a simple cadence sensor. This is a game-changer for trail riding! Join me for the entire process, from a side-by-side comparison with the BBS02 to removing the old cranks and bottom bracket, mounting the motor, running into some classic installation hurdles, lengthening the chain, and setting up all the electronics. Finally, we'll take it out for its maiden voyage to get some first impressions of how that torque sensor really feels on the road.
