I can't say for everyone else but anyone I knew... Either the teen bought an old clapped out minibike with their money that got ridden on the streets and trails or the parents did buy them a proper MX but took the kid and the bike to proper off-road trails and they rode together with them on their MX.
My bil lives in Woodbridge. The parents that are entitled aholes that believe the hta doesn't apply to them get bikes/scooters for their entitled ahole kids. One dad rides a Chinese gas pit bike with his small son on his lap along the sidewalk daily at 50+ km/h with no helmets. No brain to need protection.
Those are a grey area. By almost every definition you can find, they are Low Speed Vehicles which are technically part of a pilot project but almost no municipalities are participating in the project. The people using them are arguing they are enclosed mobility scooters and therefore a disability aid and they can do whatever the f they want. I call bs. Most of these are way faster and larger than mobility scooters.
The ones I have seen were predominantly the DUI/trailer trash crowd. Pushing the youth/elderly off the sidewalk as they missile along. The same ebike stores telling their customers that the 1KW "ebike" can be used by anyone anywhere added these vehicles as they are a much higher price point and likely more profitable. As with the bikes, they tell customers they can do whatever they want in them.
