Bamboo trailer
Welcome
Places that need a bike trailer
the most, often have the least
capacity to build or buy them.
Carry Freedom developed the
Bamboo trailer to allow anyone
the ability to build a strong
adaptable trailer from anything.
These plans allow a builder
to make a trailer from most
materials, with pinned joints, and
no bending or welding. Whether you
make it from titanium or bamboo,
this is a stiff light trailer. It
can be varied it in width length
and strength, and made to fold.
We are developing this project as
a non profit venture. These free
plans are funded by profits from
our western trailer sales.
Any help in developing funding
and circulating this project is
welcome.
