Complaints first, and there is not much, would be that the bike has too many branding stickers on it. 1 logo, 5 brand names, 4 model numbers, and 2 website addresses. That is taking advantage of your customer and makes the bike look like a rental or something. I was able to remove all of them with a heat gun, razor, steel wool, and some black spray paint. I wish if I buy another Wallke bike this isn't going to happen.
The bike frame is very high. I am 6 feet tall and struggle to get my leg...
