Have any of you heard of an accessory/bike mod called an Xtracycle?
Details are here. Basically it allows phenomenal cargo and passenger capabilities with very few (minor) downsides and some definite pluses for a commuter (stability, better hill-climbing grip, braking).
I am getting one of these for myself and have arranged with the manufacturers in the US to ship a group order at a healthy discount.
If you want in, or more details, please email me at: bikedeal at gmail dot com
