It is fantastic -- I trained both my 5 year old and my 7 year old, and my back felt fine the next day.  That's a huge improvement.

The trainer worked wonderfully, thanks.  My son is now riding on his own, although needing practice with starting & stopping.

It worked great.
We tried it the day we received it and after about an hour of use, my daughter was riding on her own. It was a wonderful invention.

We are very happy with the Wallaby Bicycle Trainer.  We (my husband and I ) are the grandparents --- and we really can't do the bend-over-the-bike routine that we did with our kids, with our granddaughter Jessica (age 7).

Our son (5) went from training wheels to riding on his own after 3 sessions with  the Wallaby Trainer.   It was easier to teach him to turn without having to experience the normal wipeouts.  In his words "The Wallaby Trainer helped me a ton!"
