Too bad it only has three speeds, but maybe its derailleur can be upgraded.
The EEZZ D3 uses a proprietary, narrow OLD rear hub that will only fit three (9-speed cassette width) cogs. It has a special 9 tooth top cog. I inquired to Dahon about the other two cogs (an 11T and a 13T), to find out if they're standard Shimano pattern and could be changed. Of course I didn't get an answer.
As geared from the factory, the EEZZ D3 (is this bike actually available anywhere yet?) has a
very narrow range. To be equivalent to a standard three speed IGH, it would need 9-12-16T cogs.
Dahon's published factory specs for the light, quick folding EEZZ say it is larger than the benchmark Brompton when folded, but I see pictures on the internet that make it appear that the EEZZ folds smaller. Perspective is a funny thing, though...
