    My Custom Upgrades to Stromer ST2 and ST5 (Silent brakes,Tubeless, dropper suspension post, shimano brake caliper, 11-51 cassette)

    I have to confess, I don't understand. With the ST5-Pirelli, the speed in the corner is higher then with any other tire. Especially MT tires with big amount of negative profile are allowing only reduced speed. With 52 : 51 transmission, you are at 10km/h while pedaling 75 rpm. This is far below...

    My Custom Upgrades to Stromer ST2 and ST5 (Silent brakes,Tubeless, dropper suspension post, shimano brake caliper, 11-51 cassette)

    For your Puch G with reduction gearing, AT tires are the good choice. Going slow is this cars destiny. But the ST5 is the fastest street legal E-Bike, so I wonder why you (plan to) do this bike slowing down with super slow cassette and tires?

    New Stromer ST5 LTD

    I agree, the pricing should be vice versa. The rack should be included, but those who prefer the pure bike - probably the majority of the buyers - should get a discount.

    The all new Stromer ST5 ABS

    The next step in technology is to add the ABS to a Stromer. You know the Bosch ABS system, but as Stromer is also a brand with esthetic claim, it was no option.
