Changing a standard Brompton to a Brompton electric system requires changes to several frame components to meet the more stringent mechanical and electrical safety requirements for electric bikes following the latest European EN15194 standard.  

A conversion of the standard Brompton to a Brompton Electric version would require you to replace a large majority of the components and would be at a substantial cost. For this reason, the Brompton Electric can only be purchased as a complete bike and cannot be purchased as a conversion or retrofit kit. 

Further information on the Brompton Electric can be found here.
