Bicycle bottles are made from LDPE, this is the safest plastic. Bisphenol, the chemical at issue, is not used in its manufacture. Bisphenol is is used to make polycarb bottles(The hard, clear bottles). Polycarb is also used to line cans and frozen food packaging. The study that got the attention(this was when MEC pulled the poly bottles) involved heating polycarb baby bottles. There was bisphenol leaching when the bottles were heated(But not when they were not heated) Bisphenol mimics estrogen, so it is possible for the body to react, a bigger deal for small children(What the study was aimed at in the first place. the study did not show an adverse effect on humans it showed that bisphenol would leach, in very small amounts, into the contents of a heated bottle).
