I am at Germany , and these were the cheapest bikes(Cycles).The Racing One costed me for 209€ and other one is for 179€.The reason i dont know for the tube to blast , i just filled 7 bars where recommended was minimum 6 bars and maximum 8 bars. I didn't even ride once i brought to my room and suddenly after 1 hours a noise came and air was totally out. Then i requested company to give me a complete new wheel , so company said its just the matter of tube so we can send you tube. I accepted it because i liked the build quality and all , but then i when i planned to put a new tube from my own pocket and save the one which i will get , but the Tyre was not coming out,it was so tight that i used butter knives and all,then i went to two professional they broke their 4 plastic tools also which costed 1 for 1.5€each, i knew it becoz i bought a a 3 peice set for 2€ and he then refused to change the tube. and then i mailed company that i want to return the bike , and company accepted it without any magajmari and got money deposited in 3 days . If professional couldn't remove it then that is a pain for me to keep that bike.I am looking for both rides city as well as off road , i will soon post pictures . I don't know much about the bikes , i need it so i bought it .
