Fiido fender-M1/M1Pro(optional)

But for Fiido M1 and Fiido M1 Pro bike i can reecoment few things, in folding place can mill the groove and glue inside rubber sealant then water can not come in, also over frame where is chain there need to put some roller on top of frame under chain, because chain very often when road not flat then hits frame and destroying paint on frame, all other is just perfect
