Wahoo Fitness KICKR trainer
Thanks Dan, good info. While researching the Lemond I ran across the Wahoo Fitness KICKR ANT+ / Bluetooth trainer. It is a Bluetooth 4.0 and ANT+ enabled trainer with an integrated power meter. I think I'll keep an eye on this one...
DC Rainmaker review excerpt (the entire review, see the first link below, is well written and very informative with a lot more info than this excerpt):
The unit has a maximum advertised resistance of 2,000 watts. The unit was engineered such that a 175 pound rider (at max resistance) would feel as though they were riding up a 15% grade. Due to the flywheel aspect, the unit really does feel like you're riding on a road - very similar to how the LeMond Revolution feels like you're actually 'coasting' when you stop pedaling.
Now technically they note that there's no real limitation on resistance levels or measurement. Rather, it's a function of speed. For example, if you're going a pedestrian 4MPH the limitation if 600w, but at 8MPH the limitation is 1,200 watts, and at 16MPH, the limitation of 2,400 watts, and so on. Of course, if you can output that much power. The curve is linear.
The electronically controlled change in resistance upon command is instant. Meaning that if the software removes resistance - it can go from that 15% incline to coasting down a hill instantly. This is different from most trainers tend to take a few seconds or more to release the resistance - so this is ideal for those doing intervals.
The KICKR updates the power resistance on the trainer electrically every .25 seconds - meaning that if you waver in power - it'll respond in less than a quarter second and adjust accordingly.
Due to the ability to provide resistance - the unit will require being plugged in. But the charge is minimal enough that a 12V cigarette lighter will work (so you can do workouts near your car ahead of a race). They are also considering adding a battery pack if there's demand for it.
