The DVLA wants to close more of the test centres and also says it wants to rid itself of SVA for autos,even though they keep raising the test fee,the last time I looked it was £600.
If they do introduce an SVA for e-bikes it won't happen until after type approval is introduced in 2018,the fee is likely to be very high to deter applicants.
In the auto world SVA on kit cars is almost dead,most customers have gone to body panel conversions on stock vehicles.....Ferrari lookalike on a Toyota MR2 per example. Or,companies like Westfield or Caterham who have type approval.
I see parallels here,I think the DVLA will look towards us importers to type approve,if there is a good take up, they will say that it is not cost effective to SVA e-bikes or make the test fee punitive.
Hopefully,we won't need to type approve,aside from the throttle issue,so the situation will be very similar to the current.
