The National Motorcycle Dealers Association has complained to MP Andrew Jones, parliamentary under-secretary of State for Transport, that promises around a plug-in motorcycle grant scheme have still not been delivered.

In March 2015, the coalition government announced that motorcycles and scooters would join other vehicles in receiving grants as part of the drive for greener vehicles.

At the time, the government promised that up to £7.5m would be set aside to help boost the uptake of two wheeled electric vehicles by bridging the cost gap between a zero emission electric motorcycle and conventional petrol versions.

The grant, it was said, could offer up to £1,500 of the purchase price and allow motorcyclists to reduce their running costs and environmental impact.

However according to Stephen Latham, head of the NMDA, the grant still has not been put in place for consumers, a situation he described as ‘alarming’.

He said: "We are not aware if the promised grant has been revoked under the new government and to-date there has been no further mention in action towards implementing it.

"This is now impacting on the electric motorcycle market and is discouraging would-be buyers from purchasing vehicles in wait of the grant. This has created both financial implications for businesses and consumers.

"The NMDA has written the minister to advise further as to when the industry can expect the grant policy to be implemented."
