You can see that the Mini has a much smaller folded footprint.
The seat on the Mini is not all of the way up on the photo unfolded.
On the IXFS I have added a Cat Eye computer, Topeak under seat bag, and Topeak beam rack.
Just looking at these photo's the Mini looks fun!!!!!!!

About the tire removal though: do you remove the side with tire levers, something like a SpeedLever, or by hand? The rest of your explanation makes sense to me.

I recommend practicing this at home to get an idea of what you are doing. Once you have it down it goes really quickly. I also found that it is easy to repair the old tube this way and then re-use it later. Of course you could Slime the tire but I am not really in favor of that as you can still get flats and it adds a lot of weight (much more than a tube) and it slows you down quite a bit. So do tire liners for that matter and tires like the Marathon Plus. Ill take my chances with the normal tires and carry a spare tube. Of course if I was in a very flat prone area I would still do what I do with the spare tube but go with a very flat resistant tire like the Marathon Plus.

I agree: no slime for me.
Nice pics donkeyman. Your comparison pic of the Mini really makes it look like an attractive bike.

Natness and Frazzle,
I'm really pleased that I can still do my side dismount on my VIII H 20" as I've done for all my years of Lady's bikes ... you know, right foot over the horizontal bar and down on the left hand side ... almost 50 years old and would have found it a pain not to be able to do that. I actually spent a lot of time with a measuring tape etc. trying to figure out if I could probably do it with the Downtube.

To any fence sitters, who corner like aggressive cornering on their DT FS, go ahead and change tires. I'm running Primo Comet Kevlars, 406x1.35, and what a difference in corners. At the point that the OEM tires were inducing front shock stutter, the Comets stay glued, no stutter.
(Before I'm asked, shock stutter is when the front tire momentarily slips in hard cornering, and the shock rebounds (decompresses when load is released), only to compress hard when the front tire grabs again.)

You are too damn rough on your bikes.

Granted SB11, very tough on the DT FS. Taco the crank spider, that's a first for me. In my defense, I am gentle on my Swift, the Deans, the Merckx, etc. To me, the DT FS is like a supermoto m/c, it wants to corner, not sweepers or twisties, just donuts and eights. I can shed alot of stress in 5 min. on the DT. Work for several hours straight under deadline pressure, make the deadlline, my reward: 5 min. on the DT.

Can you measure the distance from the bottom bracket center to the top of the seat with the seatpost fully extended (to the safety mark)?

Yan, possibilities on the 550mm seatpost? Anyone been able to find one of them?

I believe that if someone comes up with the right design of accessories for the DT Mini including touring racks and professional bags (maybe a front luggage for a laptop or something) chances are we will see lots of them replacing Mercs and bromptons...

But the internal hub on the VIIIH will make it easier to maintain, yes? I am not even remotely a mechanic.

I thought there might have been a torque limitation making a >500mm seatpost too hard too find, but of course that's dependent on rider weight.
No one has found a 550 mm seatpost?

I can find 550mm seatposts, but the diameters are bigger than 27.2.
How about cutting the top off the 27.2mm 500mm seatpost and inserting a 25.4mm? A couple people did this with Thudbusters, I believe. Cheap seatposts.

height of mini seat and handlebar
From the ground, how high is the mini's handlebar? What is the maximum height that the seat can be raised? What is the distance from the handlebar to the top of the seatpost at their maximum heights?
Thanks for your help.

The VIIIH's sold out almost immediately. If you really wanted a bike before the 12th I could send you mine. ;-) Maybe Yan could do something nice for me like send a Mini to ride until more came in. Honestly it would be great exposure for him if he could get one to you before then. I am semi-serious about donating mine to the cause if need be.
Regardless of what happens you will probably want to change the gearing a bit if you have any steep hills or you need to get your bicycle legs in shape.

I can't wait to try it out for myself. Even though we live in a fairly level area, I bought this to take with when we travel so I will be reading very closely yours and others changes to the gearing and may make that my winter project. I will also most likely be changing out the grips on the handlebars, I don't want to have a great ride ruined by numb hands. Is this like changing out the grip on a golf club or more involved and better left to LBS? A quick primer would help if you think it's something I could do.
