petercycles@foxmail.comI've built two hard tails for my kids on his CS-016 frame in 14" size.
They were tall as you.
The rigid fork, is not that expensive and for me a good option for an ultralight easy to ride bike.
Frame and fork, can be custom painted.
Beware this is a 26" wheels bike with quick releases axles.
Which is not the most modern design, but you will get very good prices on your fork and rims/wheels.
