Hi Origamist (and others here),
was alerted to this thread by Google and could not resist responding. To make things clear: Yes I am who my nick says I am. I manufacture the RaptoBikes and am therefore slightly biassed.
As Fards has also found it is an easy bike to ride. On my webpages there is a video of me driving it 'hands free'. I can also ride the bike hands free while pedalling, it is very forgiving.
The front wheel drive works well. The chain, derailer and cassette are (and remain) cleaner, since there is no long chain that picks up all the dirt from the frontwheel. Also the shifting is very direct, since the cable to the derailer is a lot shorter.
The bike is very low and the seating position is right in the front of the frame to ensure that your front wheel has enough pressure put on it to keep grip in normal circumstances.
I will (try to) not make any commercially tainted posts. Feel free to contact me or Bikefix if you have additional questions.
Best Regards,
Arnold
