Depends what you mean. Usually, distributor and wholesaler mean the same thing - someone who sells on to shops/online stores, and they then sell to the end user. If you mean you want to sell them, doing it online only is very very hard; most brands want to protect the bike shops by only working through outlets who have at least a trade counter, or better a storefront. I work as a sort of marketing agent with Downtube in the UK, but the sales go direct to them, and they ship the bikes - they wouldn't work with me as simply an internet dealer.
