Hi,
I own an Omnium cargo bike, with a 750w, 48V TSDZ2 mounted on it. I am thinking of selling it and getting a Riese und Müller Packster 80, with a Performance Line CX gen2 motor. I go uphill a lot.
I once had the opportunity to ride the Packster 80, but only for about 5 minutes. The Bosch drive seemed to work much more "flawlessly" if I can put it this way. Although it is only a 250/350W engine, it seemed to be much stronger, delivering it's power much better. When I stopped pedaling, the motor cut off almost instanteniously. The TSDZ2 takes a noticable amount of time for the chain to come to a stop after I stop pedaling. This makes changing gears on my IGH a hassle, because I am always waiting for the motor to come to a stop.
The TSDZ2 seems to have a lot of flex somewhere inside - either the crank axle itself, or the motor somehow, I don't know for sure.
On the TSDZ2 I regularly reach the motor's max. cadence, when I loose all support from the motor. It is very annoying, because with my current gearing, my max. speed is around 34-35 km/h, after this the motor cuts off. The Bosch has much more flexibility in this concern, as I can spin the cranks faster, and still get help from the motor.
So my question comes down to this: has anyone had the chance to properly compare these two mid-drives? Is it just me feeling that the Bosch system is a much better tuned system, and is a much better feeling to ride? (Edit: I am talking about the stock firmware for the TSDZ2. I am aware of casainho's opensource firmware, but I still have 2,5 years of warranty on my drive which I do not want to void by installing it. And it also wouldn't help the flex and the cadence-issue, for example.)
Thanks!
Zoltán
