Do you think an electric bike is something you will use all the time or just maybe a few times per year? If it's something that you think you'll use every week, then you might want to get a really good one like a Torker or a Schwinn. Something that got good reviews. If it's something you just want to use a few times per year, wal-mart has electric bikes for about $500.
