For owners of Sumovores purchased prior to May 2005, this kit solidifies your Sumovore with a powder-coated steel baseplate!
Our initial release of the Sumovore revealed that our motor & battery pack mounting solution wasn't as robust as it should have been. Our solution was to engineer a steel plate that makes your Sumovore motor and battery pack mounting much more secure.
Besides increasing the stiffness of the chassis, it also increases the mass for better traction!
Just to reiterate: You DO NOT need this if you are ordering a Sumovore now. It is only useful retrofitting zip tie versions.
