BAMBOO BIKE????

Recently i found a new but weird stuff which is doin  bike with just bamboo......first i thought it was not goin to work or maybe its just fake.But after doin a lot of reseach i found that it is true and i found many evidence bout this bamboo bike online.But the biggest problem is joining all those bamboo together.There are some kind of thing used for this proses.Some bike they are using carbon fibre string,fibre glass and hemp fibre and string.In Malaysia carbon fibre would cost me fortune.So,the only thing i can use is fibre glass and hemp.I found out that the hemp is the cheapest and im heading for that option but disaster struct.Malaysia banned hemp for some reason which i dont know until now.So u guys out there esspecially Malaysian who maybe saw or found these hemp string please let me know please.Im gonna make this as my holiday project.
