The 400R required an external battery pack (not included in weight figure). A 2-cell and 4-cell option are available. The specifications shown here are for the 2-cell battery; the 4-cell battery adds $30 and approximately doubles runtimes. The 400R cannot be quick-released and is semi-permanently attached to the bike.
