A bike shop simulator set in 1816/17 europe, the year without summer. Desperation spreads across as the eruption of Mount Tambora sets off a global volcanic winter. The crops are failing, people are starving, crime is on an alltime high. Because of this, Baron Karl von Drais invents the "Laufmaschine", the first velocipede, as substitute for horses which died to starvation or mass slaughter. You are one of the manufacturers sent out by the baron to bring the invention to Paris in france. You have to build up supply and production chains, set up shops and hire salesmen, deal with restrictive regulations of the city council and lobby for new street pavements to improve the mobility of your invention.
You also learn soon that you have to hire mercenaries and private detectives to protect your business from criminal gangs who are trying to employ protection racket on your shops. And then there also is this mysterious group of hooded people with anonymous members spread across both bourgeoisie and aristocracy, who try disrupt your business and blackmail you into store closure because you "intervene with the great plan"...
