Crazy sliding folding Pop-cycle bike on kickstarter-
Curious what everyone thinks of this wild sliding bike I spotted on kickstarter. It's called Pop-Cycle and I don't quite know what to make of it.
There's a lot of strangeness or perhaps it's innovation. The video shows a sliding mechanism and peculiar chain setup. The gentleman says, "We also consider our environment alongside pop-cycles convenience. Most bikes produce hazardous substances like chrome and nickel while welding. By applying die-casting methods there is no need to weld the Pop-cycle. All we needed was bolts and nuts to fully assemble it. Bikers will also be able to enjoy the joy of building their own bikes like a DIY project". There's always something new ha!

I have seen a few Giatex bikes ages ago. For those who are interested, here is a video review of one of the earlier models.
Never got to test ride one though.

Nothing new here. See Gaitex. Others have had folding handlebars. It's funky looking. Did they tell you the weight? Is a bolted assembly really superior welded?

This pop-cycle bike is bs. The video tries to make a Brompton look like a nightmare to fold, and claims to be the first bike of this type ever to be brought to market.

• Doesn't fold shorter or better than side-folder (Fnhon Zephyr, etc).
• Two-speed crankset? Doesn't sound as good as a 9x3 IGH w/cassette.
• Die-casted instead of welded. I'll consider that a plus if it's truly better. I don't know enough about it.
• DIY aspect? How so?
• Will it be possible to properly convert it to drop-bars? Best case scenario is that it uses standard, aftermarket handleposts, such what's available for Dahon/Fnhon designs. If not possible, no deal. I setup all of my bicycles w/drop-bars - even my folding bicycles.

The chainwheel drives a small cog on a jackshaft that has a larger cog that drives the rear wheel via a second chain. This 'steps up' the gearing for small wheels without using a relative huge chainwheel or relatively tiny rear cog.
Here's Popcycle's gif (from the perspective of the ground looking up at the bottom bracket):
The old Mobiky did this because it used 12" wheels. Seems unnecessary, heavy and complicated for 16" wheels.
