Lithium-ion cells, the chemistry in virtually every modern e-bike, slow their electrochemical discharge reaction in cold temperatures, which raises internal resistance and reduces the energy the pack can actually deliver. The battery management system that protects cells from damage becomes more conservative in the cold as well, throttling available power to prevent stress on chemistry already working at reduced efficiency. Together, these effects mean a pack rated at 500Wh under test conditions arrives at a real Front Range morning having lost a meaningful portion of that accessible capacity before the first pedal stroke.</p>
