Berini

Berini 32cc auxiliary engine.

"The Berini M13 was built in Rotterdam from 1949 to 1961. As it was developed from the Cyclemaster, engine size was initially 26cc, increased to 32cc in 1951 (the M14). In the Netherlands, it was known as “the Egg” because of the shape of the fuel-tank (designed by welding two headlamps together from a DKW motorcycle). The Berini was the most popular Dutch bicycle engine and could reach up to 30 km/h.

Affectionately known as the ‘Little Egg’ Berini was one of the top Dutch cyclemotor manufacturers. As well as this very popular model, the company also sold Cyclemasters under license for the Dutch market.

The Berini M13 is a very well-made machine. It was exported to great Britain, and received good reports in the motoring press of the day." (from oldbike.eu)
