How do I maintain an eBike chain?

Clean the chain every 100-200 miles using a chain cleaning device and degreaser, then apply chain-specific lubricant (wet lube for rainy conditions, dry lube for dry conditions). A well-maintained chain lasts 2,000-3,000 miles on an eBike. Let the lube penetrate overnight, then wipe off excess before riding — excess lube attracts dirt faster than no lube.
