Overall a satisfactory trip! The GPS is very useful for navigation. The hotels are great! Just on first day, we find that 2 of the 4 bikes are not fit. We have enter our age and height and has not been told specifically what kinds of bikes will be assigned. I found that they just give standard bikes for adult female and male disregard our height and age (Asians in average are shorter than Westerners.) The person, Robert, arrived for “bike fitting” was not helpful at all. He suggested my daughter to cycle 30km to their bike shop to change bike. When we asked him to call customer service, he said he didn’t have Wi-Fi. So, Eurobike send a staff without communication methods to help customers’ solve problems? Finally, Robert had to use my phone to call the CS number. And in the phone, he said we are “bla, bla, bla.” Is it the customers cannot voice their requests, even the bikes are not fit and customers have to take the risk of getting hurt or accident? and seems to Robert, customers’ requests are “bla, bla, bla..” And customers need to take the riding risk to go 30km to change bike? Later he mentioned it may need to charge EUR 50 per bike change if need to switch bikes in Passau. I have emailed biketour and I am grateful that next day the 2 bikes were changed without additional charges. In second day, Simon is much more helpful. Simon helps us do the testing & it works. Simon is v polite and helpful. Passau is the starting point of Danube cycle path. I feel strange that the outsource company does not have a bike rental centre there. This is our first family cycling trip and it did create stresses at the beginning. The outsource company probably need to have better communication with biketour.
