Take a look at the new Torker Cargo-T bicycle available from your Local Bike Shop in the United States.
Seattle Bike Supply has apparently listened to their customers with cargo bikes, because the Cargo-T with its 4130 Chromoly frame and fork has very practical features like a sturdy center kickstand, a step through frame, chainguard and fenders. Other features are a rear coaster brake and front roller brake, headset lock (to keep the front end stable as you load and unload the bike), Sturmey-Archer 3 speed hub and a bell.
Besides this eye catching flourescent green, the Torker Cargo-T is also available in satin gray.
The Torker Brand is distributed through Seattle Bike Supply, so any bike shop in the USA using SBS as their distributor can order this bike through their catalog. MSRP is $599.99, which seems like a pretty good deal to me.
