Can we get smaller frames and wheels?

Leif, I am 6'2" and my legs very lightly hit the bars. The fit otherwise is perfect so I have gotten used to it. I have a long torso and medium-short legs so maybe that is why it works on my V20.

Just goes to show a one size fits all approach doesn't work except for those who happen to be average size and americans tend to be taller than most other people around the world (except dutch and german). I'm no engineer but surely making differing seat height mountings and shock absorber mountings wouldn't take a major redesign. Also offering a frame set so it could be built up differently. The fact this thread is here shows I'm not the only one. So there is a demand even if it is small for both bigger and smaller people to have a choice. DF manufacturers don't sell lots of their biggest and smallest frames either but still offer them.
I live in Cambodia so rough, mostly dirt roads is all I have to ride on. So I could try a T50 but suspension sure would be nice.

Messing around with 16" trike wheels on my home built mbb , no discs so no brakes, super low and handled the same as with 700 wheels

So absolute minimum needed would be smaller wheels. Disc brakes would not require any change, higher gearing would be necessary to maintain same top speed. Anything else?

An adjusting redesigned on size fits all chain stay maybe......sliding or multiple qr positions.....
With the CF Silvio front suspension chainstay extensions of 50, 100, and 150 mm,near the BB, were available and VERY helpful for adjusting the BB height!
The Quest V1.0 had two chainstay lengths available for 507 and 559 wheelsets!
What % of Quests were 507???

The early vendettas had 3 chainstay lengths available, then 2.

How many chainstay lengths are available for the Q45/S40/V20, as all the same no suspension?

I think that different length chain stays would be a cheaper option, than having the BB area with an different length inserts, with 2 joints instead of zero joints.

There are several chainstays available for the S40, V20, and Q45.

16.5, 17.5, 19.5, 21.5, 23.5

Not all are always available heads up - we actually have a 95% fit rate for most riders which is awesome with a single frame size. The bigger issue is the one size fits all seat that of course adds a layer of fit complexity even above and beyond the chainstay. Stay tuned, however, as we are working on that as we are always working on everything

Longer is not always “better” depending on the bike even for taller riders. There are many issues in a fit other than just raw BB height.

Lots of moving parts and complicated adjustability in a single bike sounds like a great engineering solution, but only ends up in a highly adjustable mess that results in a floppy janky heavy bike that costs a fortune to manufacture. Simple is always better and swapping simple parts for fit makes more sense for us.

The bigger issue with multiple frame sizes is logistic - we have to manufacture X number of everything and less numbers = more expensive. Upright bike companies do not have the same market number constraints as recumbent companies.

Any possibility for a Q45 frame set? I've got lots in the parts bin and like this thread would love to build with small wheels for small riders (my kids) exposure and for portability when I travel each year.

So I'll add my request for a Q45 frame set, if possible.

Hi Robert hope your injuries are on the mend.

Can the seat height (25") on the Q45 be reduced, as it looks to be 3" too high, as there is a huge gap from the seat underside and the frame.

Another option could be to add 2 extra rear shocker top mount points, forward of the existing, to raise the rear wheel, and hence lower the seat.

Q45-25"(26" wheel), S40-24"(700c wheel), T50-22"(26" wheel), V20-20.5"(700c wheel)

We do not have anything currently in the works (but there is always a possibility) of a set of brackets intended to lower the Q45 seat. fashioning a few brackets to do this would not be super hard and would lower it around 2" or so - not sure a 3" drop is possible, and altering the shock position would change the head tube angle too much, so that option would likely be off the table on any other version of the Q...
