I contacted bicycle engine and let them know that the bicycle they sent me was definitely defective and had a hole in the gas tank and wanted to exchange it they wanted pictures I sent them dozens of pictures and a video of smoke coming from the fuel tank still nothing but a run around then when I mentioned I might be able to fix it they gave me a little discount so I can try to get it fixed not even the right way it's brand new shouldn't have any leaks anyway you have been warned beware support will do nothing but give you a parcel refund
