Am I too big for a DT mini ?

before I make the final click, I am 6 foot tall and on a good day (and if I was riding a la Sammyboy, ie nekkid) I am 210lbs.

Will the mini be OK for me, do people think?

Absolutely OK from what I've seen. I'm sure Jur is that tall easily and uses one!

At 6'3, but with a long body, I come up 1/2" short on the post. I'd guess you'd be fine with it out all the way, but it's hard to be sure!

sammy, did you get a butt buddy for your mini ? I checked the thread on this and couldn't see clearly - and, sammy or anyone else, any ideas where I might buy one retail. When I googled.... well, you can guess what happened...

I'm 5"10, but even so the original seat post was a good inch too short and then some. I was somewhat uncomfortable with over-extending the seat post, and besides wanted to have a stiffer post, so I made a telescoping one of ample length. I had a lathe for the job, no ready-made bits were to be found.

I'm 6' tall, with a 34" true inseam. The stock seatpost is about an inch too short for me. I ride with the post past the min point, but my seatpost is reinforced with a 18" length of 1" dowel stuffed inside.

The biggest risk with over-extending the post lies in the frame: The clamp acts like a pivot point, so the bit of post below the clamp levers powerfully against the seat tube. So it might crack the frame near the end of the post, or through reverse lever action (in this case the seatpost end being the pivot point) might tend to break the top portion of the seat tube off. Hence my longer telescoping seatpost - the lever action is drastically reduced.

Good thing about the suspension: Knocks are greatly attenuated.

This is my main concern with getting a Downtube Mini. I'm 6' tall as well. Is it possible to use the Brompton telescoping seatpost on the Mini? Or is that a proprietary part?

Good point, Jur. To accomodate that in my dowel solution, I leave about 5" of dowel exposed outside of the seatpost, in effect, adding 5" of length inside the seat tube.

The other thing I worry about is whether the bike can handle my 230 lbs (not including gear) on a daily basis. That's really holding me back from getting the bike.

to measure inside leg: crotch to floor - but with or without shoes ?

Seriously.

(But if in stilletos, do I include the heel?)

I'd say both lalata and gringo should buy 2009 since it has stronger post and stem for heavier weights.

I would say to steer clear of it, unless you're willing to upgrade the suspension. Someone in here (Jur, was this you?) put a rubber door-stop in the place of the existing suspension block.

My measurements are similar to yours and I found the bike uncomfortable for even a 2-mile ride to work in good weather. If you want smaller wheels, a Brompton or Strida may be better suited to you.

It can work for taller folks, but if you're both (a)tall and (b)over 200lbs, I wouldn't recommend the DT mini.

If you're still determined to get one, I have one in barely-ridden shape that I'm going to put on CL in the next couple of weeks. PM me if you like. Or if you're near NJ and just want to test-ride one before mine gets sold, you're welcome to.

I would point out at this stage that like any other bike, folders must be made to fit the rider. I fitted a longer stem to mine. It is not really fair to expect a bike to be right for you out of the box. Bikes aren't like shoes where you have to buy the right size.

I think if I were 2" taller (ie 6'), my Mini would still be fine - it would be slightly less optimal but not catastrophically so. There are plenty users who are taller and chunkier than I and find them OK.

Like me. I did 40 miles on the Mini a while back and it was just fine .

For me, no. But for the OP, who knows? If I were to get a folder with wheels smaller than 20", I'd tend towards a Brompton, but lots of folks do like the Strida. I was putting out suggestions for other bikes that he may want to test-ride, if he's able to find any available for test rides.

The OT was soliciting opinions, this was mine. I don't think it's a bad bike at all, just not a good bike "for me". Since I'm 6'0" and only about 15lbs heavier than the OP, my experience may have some bearing. As with everything in life, YMMV.

If you don't fit a Mini due to height and weight, Brompton is likely to be the same, and Strida worse.

on Sammy's last point it was my experiences with my merc (for which read brompton) that caused me to ask the question in the first place. When I got it, I think some of the problems were due to me being, shall we say, at the boundary of the size parameter. I think, fingers crossed it is going to be OK - I am getting a telescopic seat post, just to give that extra inch or so - I could have made do with the slightly longer, non-telescopic post, but as I got the merc for the fold anyway I thought it worth shelling out. When I have finished with the minor mods I am making to the merc, soon, I am going to post on this. I think it will be a good bike in the end, and much better deal than a newbrompton of more or less equivalent standing. Better than a secondhand brommie on ebay, I don't know - I will do the math and post anon.

But it seems to me getting the 2009 mini, and the ability to adjust/modify the mini handlebar reach more easily might work. As, also, might changing the pedals to ride with cleated shoes, I wonder.

But finding that extra inch or two on the mini seatpost end while not overextending would be helpful, hence the buttbuddy, or alternative, question....
