RumbleOn Inc., the Charlotte-based online retailer of used motorcycles, has raised $1.5 million in debt among nine investors, according to a filing from the Securities and Exchange Commission.

RumbleOn previously raised $2.48 million in a private placement sale on March 31, which was used for development and working capital purposes. The privately owned company did not disclose what the recent funds will go toward.

The e-commerce platform for buying and selling motorcycles sells shares OTC, over the counter, but filed for a $25 million IPO on Sept. 1.

RumbleOn plans to list on the Nasdaq exchange under the symbol of RMBL. No pricing terms have been disclosed.

Companies relying on a Reg D exemption do not have to register their offering of securities with the SEC, but they must file what’s known as a Form D electronically with the SEC after they first sell their securities.
