Biggest issue is the thickness of the motor sitting on the crank, outboard of the chainring. Could be awkward to be so asymmetric and so wide.
Weight is a bit high, at 8 or 9 kg, and battery choices seem limited to one option for each motor power. They'll probably change that daftness as 6.6Ah on the 250W version with so heavy a kit is unlikely to sell well.
Also phone as display is not for me. Don't want my vital phone so exposed to risk.
But an interesting take on mid drive. Essentially a direct drive motor on the crank, with 2 chainrings for easy implementation of wide gearing range, which allows use of cheap 7 or 8 speed components.
Let down by physical size and weight, especially the 250W version which looks like it shares the casing with the 1500W. And no torque sensor, so not competing with TSDZ2.
