'pipe bike' by bruno gavira
developed by spanish bruno gavira, the children bike made out of 100% standard PVC drain pipes, where the saddle has been modeled
from a 110mm drain pipe using a hot air gun and cut to shape afterwards. joints are put together with PVC glue or screwed depending
the effort they have to support. the wheels are taking from a beer case crate trolley, and they have inner ball bearing included.
axel hubs are the only steel pieces in the bike, with an industrial 8mm. thick piece of felt to make the saddle comfortable.

This is ridiculous. No way to propel oneself on this thing. Another ad.
It’s a great balance bike for kids. Standard material utilization at it’s best
)
It’s a balance bike. Kids use their feet to propel themselves, and it helps them learn to balance so they can learn to ride a real bike better when they get bigger.
I made this for my son’s use. believed or not, he was using it for a year, untill his size was too big to be comfortable in it. now is still working with other kids when they visit home.
Great design bruno! Love it. Perfect as a balance bike.
Well done Bruno! I love it!
that’s is exacly what that id, a BALANCE BIKE!
This is wonderfully simple and brilliant at the same time. I would have had a blast on this when I was a kid and the points about it being a balance bike nails it. Lovely.
Congratulations!
just one thing PVC is toxic… not sure if it’s really good for the kids
well, PVC is toxic in its process of fabrication. once done, it isn’t more dangerous than many other products. Anyway it is not an object to lick, so what is the main problem about it?
