I am selling my single speed from the brand Tretwerk, bought a couple of years ago. Super pretty, light bike in black with brown details. Overall in good conditions but needs some love and attention: the tires need to be replaced (currently flat) and a little oil here and there. The brakes work well, only the brake blocks could be renewed at some point.
See pictures for signs of use. I am 1,68 for size reference. Contact me for questions!
