Since yesterday, my TSDZ2 started to be noiser, a lot more noiser. Because it increased gradually, it took me some time to consider it as a problem. This morning, I was louder than a scooter: https://youtu.be/cWJxAJMwrGI
I extracted every single part of the motor for nothing, the noise was coming from a vibration with the frame. I inserted a piece of inner tube between the frame and the rear attachment of the engine, silence came back. I took advantage of the dismantling of the engine to lubricate it and to check the nylon sprocket. Everything is fine and smooth after 200km (125 miles) and 80% of the time spent with maximum assistance.
Regarding the speed accuracy, with my 700x23c wheels, "28" doesn't work: it underestimates speed and distance. The best result is achieved with the 26 inches setting, with a deviation of 2% for both speed and distance.
