Subject: Kurt Kinetic Speed question (and power, too)
Santa brought me a Kurt Kinetic Road Machine for Christmas, and so far I'm liking it. Stable, smooth and quiet.

My questions:

1. When I ride outside, I usually average around 19 mph. (I'm still a cycling newbie, but I'm working on it. ) On the KK, I rode around 15 mph, with what I thought was pretty good Rate of Perceived Exertion, similar to my 19 mph rides. Anyone else notice this with their KK Road Machine, or am I just dogging it?

2. I found two different formulas online to convert speed to power for the KK Road Machine, I'm using this one in an excel spreadsheet: P=S^3*0.019168+S*5.24482. Is this the correct one? How accurate is this power estimation?

Thanks, BT!

Hey,

I dont have a whole lot of input as i am a cycling noob too. I have noticed the same thing however. I was riding about 20 mph on the road. I got my trainer for Christmas and it was kicking my but at 18 mph. I normally can get a descent ride in at 16 mph. Maybe we will get some good info here.

Speed is not a very good indicator for indoor training. Time and power is a whole lot better… so don't stare at your 16mph vs. 19mph outdoors.

I have no clue how accurate your power formula is, but just recognize that it is an estimate. Since you are using the same formula, on the same bike and trainer, the deviation will be fairly accurate. In essence, if your calculated power is increased by 5W as a result of your training, I bet that will be fairly accurate. If you are asking if that means the 200W you produce is accurate, then I would venture to say no… but honestly, it's the delta that is really interesting anyways...

1. I found out that I did have the right formula, so I made an Excel spreadsheet with MPH in one column, and POWER in the other, and hung it next to my bike. Still pretty pitiful power output, but I'm improving!

2. The general thought was to not worry about converting trainer speed to road speed. Just be consistent in pumping the tire to the same pressure, and tightening the pressure knob the same number of turns each time. Then you can track your avg. mph for your trainer rides to look for the improvement.
