Bike Trunk How-To

bike trunkHere’s a good winter project to soup up your utility bike—a bike trunk. As the author of osaurus.us says:

A bike trunk adds a huge amount of cargo space to a bicycle, and costs only $10 if you already have a rear rack. I wonder why these are not mass produced.

Bike trunks are a joy to use. I originally made one to transport my first puppy, but both my wife and my puppy thought this was a bad idea. Since that singular setback, I’ve used it for hauling groceries (notably big, light stuff that doesn’t want to get smushed) and 25lb bags of dog-food, mulch, potting soil, etc.

  • Get ready for a wobbly ride with any sort of weight that high up.

  • I guess he does state that he’s only using it for ‘big light stuff’, but am agreed with rogbie- unpractical for anything large and of significant weight. There’s a whole bunch of DIY bike trailers going around on the internets which would be a better solution for weighty items albeit a bit more costly to manufacture.

  • I agree with rogbie. I’ve ridden with my daughter in a behind-the-seat carrier, which distributes a portion of the weight lower toward the rear axle and slightly more forward toward the seat tube, and that was still a wobbly ride. Otherwise, though, it’s a cool (and very economical) idea.

  • Aside from wind, hit a patch of bad road and that trunk will start steering the elephant. Panniers for heavy stuff and a rucksack tied on top for light stuff like bread and cereal is a far better way to go.
