Ride quality shocking

If the tyres are overinflated, that would impact ride quality.

Check there is no play between the passenger seat and the shell. It may be the seat runners are worn or simply not bolted down properly.

Wheel size v. tyre wall ratio?

"stylish" narrow-wall tyres have a stiff walls an give a hrad ride.

Loose seat should be an MOT fail, anyway.

Has it been fitted with lowering springs in the past?

I wondered that, but then noticed it's on fairly tall tyres. Chavving-up would probably start with rims.
