One company that made medium-duty electrically powered trucks has ended production, but says it has not gone away entirely.

Boulder Electric Vehicle is no longer producing its trucks at its California and Colorado facilities, according to the Los Angeles Daily News.

In an interview with the newspaper, CEO Carter Brown said while the company has been mothballed, it is not filing for bankruptcy and is still servicing its vehicles. He said the reason for the move is sales were not at the level the company had hoped.

The ending of production began several months ago. The company’s California facility is now occupied by another business, while Boulder has put its manufacturing equipment in storage, according to Brown.

Boulder Electric Vehicle reportedly came out with its first truck more than two and half years ago. Last September it demonstrated its all-electric trucks in Michigan, Colorado and California.

The move by Boulder follows Smith Electric Vehicles earlier this year suspending production after losing more than $127 million. Later the company received a $42 million investment by a Chinese company to resume operations.
