Understanding Weight and Power With Cargo Bicycles [bicycleastronomy.org]


“Isn’t that thing heavy?” I’ve had a few people ask me that already. The Yuba Mundospecs out at 48 pounds, and that’s probably calculated with no cargo and few of the common accessories like running boards and a side-loader bag. Let alone that copper bell I added! Probably my daily running weight is about ~65 pounds. Certainly it’s far heavier than the 8-pound carbon fiber wonder Jim Hogan at GBC let me hold a while back. It was so light I almost threw the bloody thing through the roof of the store, just trying to pick it up. I expected it to have some weight. It appeared to almost need to be held down.
Does it matter how much your bike weighs? Certainly if you’re a professional athlete, or an uber-serious amateur, it can matter. That $11,ooo carbon fiber frame might shave a portion of a second off your time, and that might be enough. If you’re going to compete in a mega endurance race like the 3,000 mile Race Across America*, probably a big cargo bike isn’t your first choice as well. But for most people, should bicycle weight be a big concern? And should it shy people away from grocery shopping by bike?
I was a bit worried getting such a big, heavy bike as the Yuba Mundo. My specific worry was Washington Street. On the way to work, it’s all downhill, but on the way home, well, let’s just say I do wish it was reversed. It’s somehow not fair that I can get to my office in 3 minutes but it takes me 10 on the way home. I won’t show you a picture of Washington Street, because you would see how puny it is and therefore what a weakling I am. But it’s my hill, and I wondered before the Mundo arrived how it would do on that long gradual climb. Notice that I said how “it” would do. You know, because, it’s all about the bike. (Not my legs or cardiovascular strength.)
