I'm looking for a folder for 10-20 mile training rides (not commuting), and think I have narrowed it to the Tern x18 and Reach R20. Any reason to choose over the other? My only requirement for the bike is that it fold small enough to get into my apartment and that it have either drop or bull handlebars. The Swift would be a clear choice except that it doesn't seem to fold quite small enough for the apartment, and I don't want to have to take it apart after every ride. Are there any others I should consider that may be cheaper than the Ten of Reach? Suggestions welcome.
