HUNTINGTON BEACH, Calif. (BRAIN) A fire that started at the Rad Power Bikes retail store here on Sunday night is under investigation by the Huntington Beach Fire Department.

Were working with local authorities to review a thermal incident that occurred at our Huntington Beach store Sunday evening, a Rad Power Bikes spokesperson told BRAIN. The incident was contained and happened while the store was closed. The cause of the fire has not been confirmed.

Huntington Beach Fire Department responded to the blaze at about 7:07 p.m. at Pacific City Mall, home to several other merchants and restaurants.

While we can confirm there was a response to this location for a reported structure fire, the incident is currently under investigation by Huntington Beach Fire Department Fire Investigators, so we are unable to release any further details regarding the nature of this incident, a Huntington Beach Fire Department spokesperson told BRAIN.

In November, the Consumer Product Safety Commission issued a warning about some Rad Power Bikes models because the lithium-ion battery can unexpectedly ignite and explode.

Rad Power Bikes did not agree to a recall, according to the CPSC, and the brand told the agency that given its financial situation, it can't offer replacement batteries or refunds to consumers. In December, Rad Power Bikes filed for Chapter 11 bankruptcy protection in advance of completing a sale of the company. The Rad spokesperson said Wednesday the company continuesthe bankruptcy process as it searches for a buyer.
