Messy answer to difficult question. I have had some interesting conversations with several different agency engineers; that is, no agreement; so just tell them which standard to use. USB cannot always be considered LPS IAW 60950/2.5, so would test as 'dc mains' device. Most NRTLs will gladly take your money and certify as an 'ITE Power Supply'. If any part of output power exposed to user, or if outputs of your charger must be class 2 -> UL1310/CSA223, otherwise you could use UL1012 if you did not want to use 60950-1.
Carefully read scope clause for 60335-2-29, may not be applicable to your device.

The charger is intended to charge the battery located on a bicycle frame. Also, what are the applicable North American and EU standards applicable for this battery charger?
