As i know all tsdz2 make big sound
One of mine is as silent as the grave, the other is loud enough to hear over talk radio at full volume with ear-buds on! ... I'm wondering which one is the anomaly! I think most are fairly quiet these days, but have insufficient statistical data to feel comfortable with it one way or another.
I like the output shown in that image of yours above. Since I can't read French; can you tell me if there's an English version and if so, point me to the product? (Or, obviously, if someone else knows of such a thing for the English world, please share!)

I managed to overheat/stall my 48V-15A motor. It took a 20% steep logging road to do it, though.
... My computer says that your flash-embeded video is "no longer supported" but that I can still watch it on YouTube, but it doesn't give me the URL for it!
Meanwhile, bjorsa brings up cadence. Without a device to measure it, I'd only be wild-assed-guessing, but my perception is that my one unit ("15A") gets my one bike up to over 25 MPH to maybe 27 with assistance, the other ("18A") has trouble getting me over 20. Not sure what's up with that yet as I haven't been able to do side-by-side tests yet due to a leg injury. Both bikes have the same gearing. The slower one is lighter but has 2" tires while the heavier one has 1 1/4" tires.... I have a hard time believing the tires are making that difference!
And, speaking of performance, with my bum knee, I've not been able to add much of anything to whatever the "18A" motor gives (the one with the throttle), but have had to run errands and such, so I'm paying attention. Yesterday I went out on a 7 mile trip over nearly completely flat ground - only two freeway overpasses, one each direction outbound and return - and got about 2.01 miles per Ah. I consider that pretty good considering what I added via pedaling was just about nothing.

Is there a difference [between coaster brake and non-coaster brake units] in the Serial Numbers or does the motor lock up if trying to turn by hand?
Just to clarify what Speady said: On the NON-coaster system, if you pedal backwards, the chain ring (and hence chain) doesn't move backwards with the pedals. On the coaster system, if you pedal backwards, the chainring also moves along backwards. So, it's unlikely they'd bother to track which systems got what, but who knows, it COULD be encoded in the serial number, but so far nobody's talking!
