This is really worrying. A lot of kit and DIY (i.e. from parts) builders do all they can to make their bikes EN15194 compliant, both to avoid seizure and to just do the right thing. Having a sticker is part of compliance and not having one has been used as grounds for seizure, so in effect they're obliged to fit one, often self-made to show compliance information without falsely claiming type approval or UKCA.But as above, using a fake sticker might seem harmless but is almost a guarantee of a prison sentence, suspended if you're lucky and if your previous record permits.

To even consider it would be stupidity of the first order. It seems a harmless wheeze, but people don't seem to appreciatew what bad ju=ju any type of deception is in the eyes of the law.
I've very little confidence that magistrates would appreciate that distinction and that no deception was intended. Equally the police have been inconsistent in understanding that Throttles are legal provided they only function while pedalling or below 4mph (unless in use before 2016), so what hope is there with labels?
BTW in London gaffa tape is to deter battery theft, better warnings are vulnerable or damaged wiring and 'dinner-plate' motors.
