Bringing up this old thread since I just bought a new 5.0 in orange.
I have a 6kg Dahon Dove, but I have to bag and carry it in the Bangkok subways.
That got old very quick, so I caved in and decided to get an orange Strida 5.0

Pluses:
+I love how easy it is to fold and push through a train system.
+Great brakes
+Quality of finish. No rough burrs or shoddy welds, great paint finish.
+Robust design. I have the older (non-reinforced) frame style but it feels plenty stiff when riding.

Minuses
-Stock seat is junk. The optional Strida springer seat should be standard since the riding posture is so vertical. I swapped in a Brooks B67 springer seat the 2nd day riding.
-Heavy. Stock, my bike was 10.21Kg I would not want to carry this up stairs. Luckily my train stations have escalators.
-Non standard parts won't allow lighter upgrades.
-Low gearing (53.3 gear inches). The bike is very slow cruising (I prefer 80 gear inches on my singlespeeds).
-Reflective sticker on front tube is too wide so the edges are always peeling up.

In summary, if you are going to pack into a train or bus this bike is perfect so long as you don't have to carry it far or need to ride it fast.
I'm very happy with the bike, but I now debate getting an EVO 18" when better color choices come out so I can cruise faster.

How can Ming Cycle make this bike better? (wishful thinking)
1. Thinner reflective strip to prevent peeling.
2a. Make the eccentric BB accept BB30 bearings and then people can upgrade to any crank spindle they want.
2b. Make the chainring a standard 5 hole 130BCD so at least people can swap in lighter crankarms.
3. Optional carbon handlebars that are actually lighter than the AL ones. This bike is very low stress, it can take lightweight handlebars.
4. Bigger chainring/longer belt. With the EVO's front frame holder, there's plenty of extra room when folded for a larger chainring.
5. Optional carbon wheelsets. Imagine LT style wheels if they were all carbon. Since all the braking force is at the hubs, they could be very light.
6. Optional carbon frame. This bike's riding posture doesn't provoke aggressive riding/stunts so it would be perfect to make out of carbon fiber.
7. Design a lighter folding pedal, no one has for some odd reason.

I know I am dreaming but if this bike was mostly made out of carbon, it could be super light since there are custom 700c road bikes weighing less than 4kg.
A stock 2013 C-dale Supersix Evo Black is 5.2kg.
A carbon Strida would cost a ridiculous amount but some people would buy it just to have the lightest bike possible.
