Help pls. Bike trailer seen

[Pink Angel]

Ok, some of you guys might think I have lost my marbles, but the other day I saw a car towing a motorbike. But the tricky part is, the bike was being towed by a small device that attaches to a bull bar. It hitches the front wheel of the bike, onto it and then the bike is secured and is towed with the bike's back wheel still on the ground and moving. (I hope I have described that right).

Similar to a car being towed whereby the front wheels are lifted but the car's rear wheels are still in motion and on the ground.

My question is, I have tried to find out who makes these or where they sell them.

Can anyone help? Please

I have googled, but no luck.

Four wheels move the body, two wheels move the soul.
