I just got a Dahon Boardwalk D7 this past Saturday and I've taken two test rides. Keep in mind I haven't ridden a bike in a long time. Goal is a 10 mile commute.
Anyway, I'm having a tough time with the hand signals. I can do it okay at a casual pace in a parking lot but at any reasonable speed I can't take a hand off the handlebars safely to point left or right. No way can I do it slowing down. At first I thought it was just me being a n00bz0r but I recently read a review of the Boardwalk where the author, an experienced cyclist, said he had a hard time signalling because, he said, of the funky shape and in particular because of the handlebars. Though I haven't ridden a full-sized bike in many years I can see how the extended handlebars and small wheels together would make the bike much more in need of constant handlebar supervision compared to a full-size bike.
What do you all think? I'm one of those freaks who, in a car, will signal a turn on a deserted road at 4 am, and if signalling is feasible on my bike then I'm all for it, but if there's a limitation inherent to the bike design then I can let it go.
