My father has problem of bad legs and also has pain in his back. He was not able to walk straight as well or do other strenuous exercise. Doctor later advised him to use exercise cycle but it was quite costly and we thought to go for a pedal exercise for him . I chose it because it looked very sturdy and was exactly as expected. It is a perfect product as it easy to carry and assemble. The LCD display shows the amount of burned calories, Rpm , time and speed exerciser . I m very satisfied with this purchase. It's good quality, portable and very easy to use. Highly recommend this product.
