I don't get tired anymore cycling up the hills of my town! They gave me a big discount on my second order, even after I had paid, and the refund worked without problems. The customer services is quite nice and works well. They always solve my problems. The price is a bit higher. I had done a pre-order for both of my purchases and I had a problem with parts of my last order missing. I was waiting for the delivery for more than a month. But, financially, it arrived safe and sound. The delivery time is the most difficult aspect of the company. Thanks for continuing to improve the product and give us a good costumer service!
