I don't think everyone assumes that, but the market for any electric powered vehicle (even very popular models and I'd bet very few prospective buyers have ever heard of the model you're selling) is often at 50% or less, even for relatively new items - People are reluctant to pay more because they're afraid something may go wrong with it and they'd have no recourse but to either junk it or pay a fortune to get it fixed. In the back of your mind is always
"This thing is nearly brand new - Why did he buy another model and now he's selling this one?"
Two personal examples - I bought a 2 year old Mitsubishi EV with a sticker price of a little more than $30K for $8K and it only had 3,500 miles on it and was like new, inside and out - Even had that new car smell. I bought it because I already owned one just like it and knew what a great vehicle it was, but if I hadn't come along, he might have waited 6 months and had to lower his price even more to find a buyer. I also bought a 2017 Chevy Volt with a $41K sticker and only 18K on it in 2018 for $20K - Used EV's just scare people, no matter how nice and 'new' they appear. What happens if the battery goes south? Where do you get one fixed?
I bought a
Lectric XP fat tire folder to use with our motor home for $899 with free shipping. Truthfully, I never looked anywhere for a used eBike and I don't think that's all that unusual. If I ran across a nearly new XP for say $250 or $300, I might have driven a few miles to take a look . . . . but it would have to be very reasonably priced to even get me to consider it
IMO, your market is just much smaller than you were thinking and it's gotta be pretty cheap to garner much interest
