First thing to do is spin the wheel freely and see if it varies from perfectly round and straight by more than 2 mm. If so, it needs to be trued. The best thing to do would be to go to your local favourite bike shop for that. Bike wheels are so light that balancing isn't necessary.
There are other things that can create a vibration - especially on an indoor trainer. If the tires are lower quality, under-inflated or worn, or if the chain and sprockets are worn you might feel vibration, but the wheel trueness is the most likely culprit. If the vibration is very high frequency (higher than the turning frequency of the wheel which is about 2 to 3 times per second at 20 KPH) then the culprit may be the trainer which has the roller that turns about 50 to 70 times faster.

For some time now, I have been biking using a road bike (Specialized Epic) both outdoors and indoors. When indoors, I clamp my bike to a mag-trainer and just pedal for 30-40 minutes ... it's quite a workout. When I bike on the mag-trainer there is a very mild numbing vibration. I thought initially that it was because I had removed the reflectors on the wheels ... so I put them back on locating them opposite the valve, but the vibration is still there. Can anyone suggest a possible solution? . Is there such thing as wheel balancing for bicycles? Thanks ...
