Why We’re Building a DIY Winding Machine
· 4 min read
I bought this inexpensive mountain bike from Amazon last April for 23,480 yen (about $153). Funny enough, it ended up giving me an idea for the winding machine project.
It has 21 gears, looks great, and includes a basic front suspension (not high-end, but perfectly usable). And that price even included shipping. Incredibly cheap.
If this were sold fully assembled at a local bike shop, it would probably cost $300–500.
So why is it so cheap?
