Transformers Circular Saw Upgrade Velocitron ROAD ROCKET Laser Cycle

Transformers Circular Saw Upgrade for Legacy Velocitron 5000 ROAD ROCKET G2 NINJA Laser Cycle.
 
This upgrade Circular Saw weapon is to make Legacy ROAD ROCKET look like the G2 Ninja Laser Cycle version. 
Made for the robot mode, this weapon plugs into the back mimicking the originials. 
It can be attached in Cycle mode, but only fits as an extending wheel (see pics) 
If you find a better way please let us know :D 

Please note this is a 3P upgrade so may differ from images shown. 
Legacy Velocitron ROAD ROCKET not included.
