We just called to rent two mountain bikes for two days in Brda (Kozana). Honestly we first did not want to take electric bikes because this felt so old But because of a knee injury of my wife we took electric ones. Alex who brought the bikes is such a nice guy who directly gave recommendations where to go and he said, usually one does not take other bikes than electric after testing them. His bikes look brandnew and worked perfect. We have never expected such fun when climbing a steep mountain so easily. We drove almost 60-70 km a day and even in the utmost sun it was great! I can recommend this in the Brda hills to really everyone and yes, we would never take here a „normal“ bike again!
