I had one quite like that in Canada, but here it was called a Wedge.

A "chopper" was a homemade thing, taking an old, plain jane bike and affixing a set of extended front forks on it... usually just by pounding another set on the original ones by taking off the front wheel, positioning the new forks over the end of the old forks and driving them home with a ballpien hammer. If you had good connections, you could get them arc-welded in place (very nice to not have them come loose while going downhill). Then you attached the wheel to the new, extended forks.

Of course you had to have at least a set of butterly handlebars added to the new bike. But the "chaddest of the chad" guys had a car steering wheel welded to the handlebar for steeing purposes.

These were dangerous bikes to ride, especially if you kept a small front wheel. Several friends were injured on mine.

I never got in a bicycle accident myself, except when I tried to install a parachute brake behind the banana seat. The cords got tangled in the rear wheel going downhill and I was picking gravel out of my chest and arms for a week.
