11963Re: 200 pound capacity cargo bike
- Jul 10, 2010MH;
Thanks for the post and link, it does look interesting. In many respects it is quite similar to the old Raleigh rod brake roadsters that were exported around the world for 70 years or so. Similar spoke pattern of 40 rear and 32 front spokes. Also cottered steel cranks and very relaxed frame geometry. The biggest change I see is the use of a coaster brake rear hub.
Has anyone actually tried a Mundo with 400 pounds + rider aboard? That could be a loaded weight approaching 700 pounds. At that weight I would think that there might be problems with bike control, particularly when mounting and dismounting if unaided by a helper.
