I've been using the Brompton a lot more lately to get to work since the weather's warmed up, but this past winter has really played havoc with the roads, and there's a lot more construction too. It's a lot bumpier than usual, and I'm wishing I could get just a little more suspension and responsiveness out of the Brompton. I also noticed that with the new building I work in, I don't really need to fold my bike from the entrance to the office, but something that is a little more compact would make it a lot easier to haul into elevators and through doors. I then remembered Dahon had/has their midtown (?) series, and I saw a special on a Dahon Silvertip from a bike shop (not local) as well as a Dahon Bullhead online (private sale).
The Silvertip does not have Big Apple tires but I was told that BA tires should fit. The Bullhead already comes with BAs, so no problem there. I'm obviously think BAs will give me some of that suspension that I want, and the more typical diamond frame will mean a more responsive bike. The ability to fold would be a bonus in this situation, and probably would not get folded often.
On the other hand, the Bullhead has a 7 speed Shimano IGH - which I gather is *okay*. I like IGH for city riding, but I don't know how good the Shimano 7 speed hub is. It looks like the gear inch ranges stated for either bike are fairly comparable.
Lastly, the Silvertip is from an actual bike shop, even if it will be mail order, so I'd like to think I have a bit more purchase security than the Bullhead (internet/eBay/private sale).
Why not just ride my regular bike? The commute is short - about 15 minutes - and there's not a lot of open road. It basically cutting in and out from one side street to another, so I like the nimbleness of a smaller wheel, but wouldn't mind something a bit more like my full size bike.
Other than the fact that I have too many bikes anyways, would getting a Dahon midtown make any sense, and if so, which one?
