First, put out feelers to see if your customers are interested. Have you had a lot of inquiries about used e-scooters? Is it an ongoing conversation on your social media channels? If you see the need is there or is growing, you can decide how much of your budget and floor space you wish to allot to your new category.
You can also consider selling used products based on request. Advertise you are a used e-scooter reseller and take orders. Keep in mind it takes longer to build a used inventory as they are not as readily available.
You’ll need a reliable used e-scooter wholesaler who can help create a respectable inventory and continue to refill orders. Once you introduce the new category, post new finds to your website and social channels to keep people informed of new arrivals.
This helps you grow sales in your new category organically.
