100 mph bicycle?

You can't ignore the chainring. It's so big, you could serve a large pizza on it.

There was a Scwinn way back that had a chainring like that and it ran behind a car.

Here's an early 1900`s Miami Racer with a similar sized chainring...

Dude!!! That is INSANE (in a good way!)

With the rear cog as big as it is, it's really not geared that tall, is it? Interesting.

The CNET article is a great example of someone seeing something and thinking it's a new idea, when it's not new at all.

The difference is the rear sprocket. The Miami/racycle has a large rear sprocket to compliment the front sprocket. The larger sprocket makes it slightly more efficient at least on paper. The Racycle has a 40 tooth (1 inch pitch) front sprocket and a 10-11-12-13-14 rear sprocket. With the 14 rear sprocket the gear ratio on the Racycle is not much different from your standard 26" cruiser. The Donhou on the other-hand has a 104 tooth front sprocket and a small rear sprocket probably under 14 tooth from the photo. It will only be good for motor pacing. The record is currently 167 mph for a motor paced bicycle, but it doesn't look like they have any plans of trying to set a record. The 100 mph barrier was broken in the early 1940's.

Who said that they thought it was a new idea?

I saw that bike when it was in the Museum in Chicago. That collection was later sold off and move to Ohio somewhere.

I like that they reversed the fork so he could get closer to the car. Brake check!
