I can’t justify this for myself, because I already have a nice cargo bike

October 8, 2012

but if you were thinking about getting a cargo bike, the coming-soon Xtracycle EdgeRunner is a pretty nice-looking piece of work. Here’s the promo for Interbike, here’s the technical guy from Xtracycle explaining features.

I’m not sure what I could say to add to their own advertising, except to confirm that this stuff is real, meaning you really can do what you see in the video, and these guys really do know their stuff. Xtracycle’s first product (the FreeRadical) was a wonder; three attachmnt points and it’s securely on, the only mods to the bike itself are longer shift and brake cables, plus an extension to the chain. Miraculously, the derailer chain would just fit in the available space between all the structural parts. The snap deck was light, strong, and good looking, and even then the design was “open” enough that people made their own replacement decks (for example, a snapdeck skateboard).

A choice of a cargo bike involves tradeoffs, but this design made some nice ones. More torque, longer wheelbase, lower load, stiffer, and nice new accessories for carrying kids or really heavy stuff with ease. The big advantage of longtails (over the other large-bike choice, front-loading Long-Johns and bakfiets) is that they maneuver “just like a bike”; unloaded, you can walk or ride them through narrow places with relative ease (front loaders are more convenient to load, but ride less like a “normal” bike, and tend to have mandatory width, though it varies).

There’s a serious electric assist option — 910 watts; that’s almost 3 of me, meaning that I could haul a 110-pound load up a 10% grade at 12-15 mph, depending on how hard I wanted to work. That drives up the price, however.

For bonus fun, it’s a relatively open platform; the electric assist is designed to use standard connectors, not proprietary ones, and the specs for the cargo area of the frame itself are “open“.

For double bonus fun, the frame’s designed by the fastest (self-propelled) man on earth.
