Bike Trainer very different from the road

[spokewench]

This may be naive, but why is balance on rollers harder than road biking? How to you climb on and start up?

I like my trainer because I can concentrate on TV, or zone out for a while but my arms and rear get sore from the rigid, locked-in position.

You can ride off the side of the rollers and they are moving too. The road does not move and usually, you can't ride of the side of the road unless there is a real lip on the side of the road.

Try them once, then you will know what the difference is!
