Sorry, the Pirelli Cylc-e will only come with the Stromer ST5. All other new or continued Stromer in MY2018 will have the usual tires.
I've Schwalbe Marathon plus since years - even bevore having a Stromer. Running with 5 Bar, never ever a conventional flat occurs (once a huge nail...). I agree, for riding comfort, other solutions are better. This week, I passed this section with the broken glass four times (videostills from the dashcam):I would be interested in knowing how much more puncture resistant these are compared to the Schwalbe Marathon plus tires.
