expresso bike

Yes, it's the training bike they have at the Y, and since I hate riding in cold weather and don't (currently) have a trainer, that's what I've used the past two years.  Since I started tracking my training on BT in January, I've logged almost 30 hours and 530 miles.

The nice thing about these bikes is you can monitor and track your progress in power, and I think it's at least "in the ballpark" accurate to a real power meter (as opposed to some of the ridiculous readings you'll get from things like ProForm or Cybex bikes).  You can at least track your progress over time.

You can also modify your seat position fore and aft, unlike most electronic bikes. 

The courses are pretty cool and break up the monotony somewhat...the longest ride I've put into one of these was about 80 minutes.  Some of the courses have crazy elevation changes that don't very well mimic outdoor riding, so I stick to the flatter courses (like Fruitdale or Quicksilver), or longer ones with steadier climbs (like Pyramid Mountain). 

You can also upload your workouts to an Expresso account and view it online.

Yeah- my gym has one too.  I've had a good time with it.  I find that I change my cadence to one that maximizes my average power for the expresso bike, which tends to be a much slower cadence than I normally cycle at.  So- I worry that it might be training me the wrong way.

However- the courses are fun, and it makes the indoor days a little more interesting.  I like the spinning bike better for a workout tho'.
