Thank you for viewing. This is a side stand from ESGE. Originally designed for 26-28 inch bikes, I've added adjustment holes, so it should fit down to around 24 inches. I've confirmed it can be used for 20-inch mini-velos, but the parking angle is around 90-95 degrees, so it's not very stable. Please use at your own risk. It has been installed once, so please be aware that there are scratches from use and installation. Product Description: Robust and stylish. The main body uses a lightweight aluminum alloy that can withstand long-term use. This high-quality Swiss-made rear kickstand (load capacity 18KG) boasts excellent stability, even on uneven terrain or when carrying rear pannier bags. Supports various cycling lifestyles, from city riding to touring. Can be installed on various frame sizes. The elegant design, combining curves and perforations, also serves as an accessory to effectively enhance the appeal of your beloved bike. The legs are adjustable and compatible with 26-28 inch bikes. Thank you. Road bike Mountain bike Mini-velo Cross bike Folding bike Single-leg stand
