Most ebikes are good these days. Mine came with a 2 year warranty and free lifetime service adjustments. I figure in 2 or 3 years I'll upgrade/replace the battery or just purchase a new ebike if there is enough advancements to warrant a new bike. You can find some good deals on ebikes right now. I got mine for $2k and it's from Trek so I feel confident they'll stand behind it. I don't know why I waited so long to purchase an ebike. I honestly don't expect that much change from lithium batteries in the near future. I hope the prices drop because that's the most expensive part of the bike.
