Loud tick sound when pedaling, difficult to find source

Hello one_half_3544

I guess it’s time for you to replace the freewheel because the belt might start popping up as seen in this post: [url]Photos of Stridas in Hong Kong]

In what kind of road conditions have you been riding your Strida to get so much wear: dust, salt, rain, mud? Or was the belt tension maybe too high?
