what's your opinion on bamboo frames?
I'd personally like it more if you could disassemble for easy transport
Bamboo bikes were a big fad about 5 years ago - by all accounts they're plenty strong enough for hard riding, but they're somewhat heavy and usually quite flexible (lots of variation between frames though). Take away the cool factor associated with the aesthetic and easy DIY frame building and there's nothing special about bamboo frames, which is probably why the trend has waned.
I would certainly buy one of those, 199 for a bike frame is fairly reasonable plus you get the "cool factor" of having a bamboo bike. If I had the rest of the parts to make a full cycle i would certainly put my money towards a bamboo frame set.
Think these things hold up well for MTB stuff?
There's no way in hell that woman rides a bike, not if she's dressed like that. Chafing of doom, it's too tight, her ass is hanging out.
I've been to Calfee. Supposedly similar characteristics to aluminum, perhaps a bit less stiff. Even though they seal it eventually it'll decay and start to get mushy, it being a natural product and all.
stupid lady doesn't even know how to use gears
Those frames are absolute garbage. Bamboo is a good material for bike frames but to get a good one you're going to be spending as much as you would for a good carbon or Ti frame.
Look into how carbon/bamboo frames are supposed to be made and then compare it to how those frames are made, they're a gimmick.
