The Dahon lineup looks good for 2006. One thing I think everyone can appreciate about Dahon is that they do a good job of keeping quality bikes affordable which is consistent with David's Hon orignal mission.
One bike I saw at the show that really looks great for 2006 is the Mu XL (replaces the Helios XL). This Mu has the Nexxus 8 speed hub, front Joule dynamo hub for the front light, rear light, SKS fenders, rack, and cane creek suspension post. Retail will be about $799.
The Hon Solo is another bike to lust for. It has a Suze flip flop rear hub for single/fixed speed, wooden fenders, leather handle bar covers, lace wood chainguard, and a Brooks B17 wooden saddle. Production however will be very limited.
Dahon is also introducing some minibikes that do not fold, but are small wheeled and easy to transport and store. My guess is that will become very popular.
