Whatâs the legal situation with these mini motorbikes? Last night we had a Kid who looks no more than 6yrs riding up and down our street and on the pavement on what looks like a Â¼ scale racing bike. No helmet, wearing just shorts and no shoes, other children playing in the street, noisy as feck. The kidâs chav father also rode with him 2-up at speeds of 25-30mph. The street's only 80yds long! Donât these mini-bikes have to be taxed/insured/MOTâd like normal vehicles? Are 6yr olds allowed to ride on public roads? I was amazed that none of the local parents came out to get their kids out of harms way. If I tell the Police, Iâll only get my car vandalised. I hate fecking chavs. Rant over.
