Here is a gear calculator that really works well:
you can always backwards calc. the kv of the motor as long as you know what speed it should produce in a given wheel at a given voltage with the gearing.
The calc I gave you a link to allows you to put up to 3 stages of reduction as well as motor speed, tire size and individual gears of both the drive (motor) gears and the driven (jack shaft or wheel gears).
I saw somewhere that had the kv of the cyclone motors, I want to say it was around 75kv, but I'm not certain.
Not getting a Cyclone, it's a 300w BMC motor that is used in Currie/Lashout bikes. MrBill, who has done some good testing of these motors, told me this morning he thinks the Kv is between 131-135.
