Project: Influence of passenger payload on the stability of bodied three wheel vehicles

Reference: S0808/V3

Last update: 06/04/2010 09:59:02


To assess the influence of passenger payload and weight distribution on the stability and braking performance of a bodied three wheel vehicle.


A motorised tricycle entering service in the UK must be approved under either the European Whole Vehicle Type Approval (ECWVTA) or Motorcycle Single Vehicle Approval (MSVA) schemes. Approval is required before a vehicle can be registered for use on the road. The ECWVTA and MSVA schemes require compliance to Council Directive 93/93/EEC (Masses and Dimensions). This includes a limit on the maximum 'passenger payload' for tricycles of 300kg. Whilst mass of the rider / driver is specified (75 kg), the mass of the passenger is not defined. There is a need to determine the risk posed by not enforcing a maximum seating capacity at type approval.


No contractors specified.
