Quite possibly the coolest motorized bicycle I have ever seen!

Actually, he said "one can do better" which I think means he won't make one per the description... so not only will it not be cooler, you won't see it either...

Are these legal to ride on city roads in NY?

http://www.zippycycles.com/motor_bicycle_law.html lists New York, but does not provide information.

So how about just buying a stock Honda XR50 and riding that on the street? What's the difference other than frame size?

Bureaucracy?

The New York state laws are very restrictive and need to be up dated. I would consider a 50cc bike or ATV as a starter using street tires and fairing. I do have the parts to build a motorized mountain bike and would love to take it to the Vetter Challenge in Ohio. It would be pretty cool too. There is no way at present to make it street legal in NY or OH. Each state has their own laws on motorbikes, scooters, and mopeds. Look them up on the web before considering any project. You may need a helmet, motorcycle license, and insurance to ride on the public roads.

The page mentions the transmission. If it's not fully automatic it's not a motorized bicycle. (They mention leaving it in 2nd or 3rd and removing the shift lever to get around that law.)

Most motorized bicycles run the power through the normal drive train that shifts.

Each state has its own definitions. PA lets you have a bike with automatic transmission and top speed of 25 mph. NC lets anything under 30 mph be a bicycle.
