Sounds like you know what it means.
Charging from the bike's electric system is really an easy problem to over come. Battery will just need to have the charger built-in with it. With Li-batteries, the proper charge method is a CC-CV (Constant Current - Constant Voltage). In other words, a constant current rate is applied first until the battery voltage reaches a certain point. Then it maintains that voltage until the current rate drop to a certain point.

Yes, "easy to overcome," but if the built-in 'charger' as you call it (I prefer 'regulator.') happens to fail, as it eventually will, hopefully it will fail safe, which this case would be to cut-off all charging. Results of a failure that results in allowing unregulated charging could be disastrous in the case of most varieties of lithium batteries
