I managed to see some nice things on the bike sharing system "Durstexpress". I prefer the name "DursteXtremeMTB" for the purposes I used the 3-speed bike city bike for over 3 hours costing about 5€. I traveled over 40km on gravel and small mountains towards Markkleeberg and cycled around the Cospudener See. This is a lake that was once an open cast coal mine that was flooded in 1993. It's a very popular nudist location it that's your kind of thing too!

I spent 2 nights here in a fairly large and boring hostel full of families and kids which was a bit of a shame and was happy to leave in search of a new place.

Nice Cow
Excellent gravel cycle tracks towards the lake.

This place is also a popular kayaking location with plenty of people on fun boats

A fantastic day for wind surfing
Not quite sure what this is for. Possibly some old coal mining relic or just a cool viewing platform.
Market Square in Leipzig
Really nice park to chill
Street in the centre, after returning my Durstexpress from its big trip near the hostel.

On the way out of Leipzig I saw a man taking a shit right outside the train station on top of a power distribution box. It was very unpleased and I had to head straight to /r/Eyebleach to clear the image of it.

On the train off to Prague via Dresden
