if you can get a 16.4mph average on theat thing, do yourself a favor and go get a real tri bike or road bike at least. It need not be expensive(BD models that would work from $299 or even an old garage sale roddie that is in good shape) and get it fit properly and you'll be screaming. With out fat tires, upright riding position, and springy front fork working against you, your bike time will be much faster and alot more fun.
