P.A.B unladen weight specification is already 20kg itself before anything was add on, as for delivery riders, there is a compulsory need for add on items which eventually will exceed the unladen 20kg requirement set by LTA. First,  riders need a handphone holder to hold handphone. Jobs are only issued thru handphone to riders. Secondly, side mirrors is a fix on type and a compulsory item for P.A.B. as for looking for traffic vehicles on the road. Other add on like headlight and taillight is also needed especially night time, some roads are very dark and night drivers can see the riders more easily. While other may had add on of umbrella holder for sunny and rainy day. Last but not least, rear rack and delivery bag a must for delivery rider. All these add on actually exceeding the LTA specification requirement. Moreover, when riding P.A.B., our body weight is the main mass which is the actual centrufugal force.
