what do you mean by overkill that it has all these features that I don't need. If so I don't mind, I plan to reuse the sensor in a later project. I just need to know if I could use this find out the angle or change in angle so i can correct it with titling weight. I found this is it what i'm looking for? http://www.mindkits.co.nz/store/sensors/imu-analog-combo-board-5-degrees-of-freedom-idg500-adxl335-1
Overkill in the respect that it's a three axis sensor and you only need one axis. But then again I don't think I've ever seen a single axis gyroscope and accelerometer combo and buying single axis devices separately won't save enough money to be worth the hassle of the more complex circuit.
To give you a straight up answer, yes, that device will be able to give you motion readings that will help you keep your bike upright. But again, as MarkT was pointing out, because all gyroscopes report a small amount of "drift" (they're never perfect and always say they're rotating a little bit) you have to be prepared for the heavy math required to work the gyro and accelerometer readings together to create a stable platform.
