Frame made out of bamboo, pictured here is a My Boo that touts a partnership with a fair trade social program in Ghana to make the frames.
It's supposed to be more ecological, for obvious reasons. Weight on one is about 15kg, which is pretty good for a kitted out city bike.
I can't speak to longevity of this and whether it actually pans out vs. say, a steel bike that you keep welding back together, on account of these haven't really been around too long. It's held together via a composite glue made out of hemp and resin, so at least they're following through here I suppose.
Reviews I've read is that the ride quality is really nice, being stiff yet compliant in the ride cases as to not make it a boneshaker.
Price of these is, obviously, fairly high, these'd run you around 3000€ euros, I'd argue a comparable bike made out of traditional materials would run you maybe 800€ new. But I'd argue it's more a proof of concept.
There are a lot of diy bamboo bike building tutorials out there, I always wanted to try but never got around to it
I rode one for a while until one of the joints de laminated. The joint was fine but it pulled away from the bamboo. Never got around to fixing it.
Did the compliancy of the ride feel notably different from other frame materials? The difference between steel and aluminum is so drastic
It's a much softer ride.
