The history of Zebrakenko bicycles may go all the way back to the early 1900s in Japan, but the brand seems to have not shown up in the US market until the 1970s. The quality seems to be pretty typical of other Japanese brands for the time period, well made and reliable. Most of their bikes are road bikes of various levels with a cruiser bike. Their head badge is a lion with a crown over his head.

The 1981 catalog for Zebrakenko states that their bikes are made by Okamoto Riken Gomu in Tokyo Japan. According to the Okamoto website they absorbed Zebrakenko bicycles in 1966. Company is now known as Okamoto Industries and they seem to be out of the bicycle business.
Sometime in the 80s the brand seems to disappear from the US market.

Value
Most of their models won’t have any great value, as there isn’t a real following for Zebrakenko. Most of their models in great condition might be worth $100 in my local market. Lighting and Olympic Ace would be the models with some value. I would think in great condition a Lighting might be worth up to $300 and the Olympic Ace $500. I have not seen either for sale so just basing on components.
