I recently posted a Craigslist link (and it is on Ebay) about a vastly modified Birdy Roholoff (Generation 3) for sale in Los Angeles for $5,000. It seems a bit rich for me, but now I'm rethinking that. I have a Brompton for multi-modal commuting, particularly when I have to use a bus on a leg (if it doesn't fit under the seat, I can't bring it on board, especially during peak hours). I have a Pacific Cycles Reach GT (that I got through Bfold) with a smallish footprint that I use for hopping on a train and then just riding around. After 4 years of this, I've decided I need a smaller fold and wider tires for the rougher roads (and a lot of hills), which has lead me to this point. I am trying to decide between the posted Birdy vs. a stock Alfine Helix or something else I have not thought of (with an IGH). The Alfine Helix is quite a bit less. Both bikes as pictured are not geared for luggage. I would have to add accessories to both, so I figure that it is a tie. It comes down to needed replacement parts from normal wear a tear. What is needed for the Birdy? The Helix is still new, so there is that unknown.
