I'm 5 foot nothing with a maybe a 27" inseam, and I tend to only feel comfortable on bikes with really small frames or really small wheels or both. I know I'm not that freakishly short and there's plenty of girls here shorter than me, but I ride better when my center of gravity is closer to the ground.
Six foot tall dudes in bike shops size me up, say, "Oh, you should be fine on this bike! My 60 year old grandmother rides one just like it!" and I get on it and it's really difficult to get on, get off, or stop/start safely, no matter how well the bike should fit.
Not to mention I'm pretty much squeaking by on the measurements. I don't feel comfortable dropping dime on either of these bikes until I test them out and see whether they're smooth sailing, or like getting punched between the legs at every stop sign.
Tati Cycles and Blue City both are listed as dealers on Linus' website, but Tati doesn't even list the brand on their site and Blue City only lists the Roadster and Mixte. Neither shop answers their phone.
If anyone owns one of these bikes, I will buy you a beer/coffee/kombucha/etc if we could meet up at some point.
Again, J, that was an admirably edifying answer. I have plans to test-ride and possible purchase (?) a Linus Dutchi sometime this week, and if it fits me and I feel comfortable and sassy test riding it I think it'll be a good fit. If it doesn't fit, I might cry a little bit and then work on importing a kid's size Batavus.
