Have you seen this cool space-saving vertical bike lift?

A simple front wheel hook is neater, almost invisible when not in use and costs pennies.  

The only purpose of this, as far as I can see, is that it removes the effort needed to pop the bike up vertically on its back wheel. Fair enough if that's a genuine problem for you, but as it's spring loaded you have to drag the bike down while compressing the heavy spring to remove the bike, which seems to negate the benefit.

When removing a bike from a hook, gravity effortlessly does that for you.  

Yeah, I saw it on the forum where some posted the link a few days ago.

I'm going to kickstart a metal threaded hook

Not to mention the problem that a bike fitted with mudguards would have with that solution. I have both SKS raceblade long and SKS Crudracer Mk3's on my bikes and both would prevent use of such a wall mounted rack. The floor space saving is not that great either, and the added hazard of handlebars at head height.

It only appears to offer the possibility of locking the bike by the front wheel ... so from a home security point of view it provides no appreciable benefit as I'm sure most insurance companies require locking through the frame ... and I'm not sure you're get a Sold Secure Silver/Gold lock/chain long enough to reach the frame from that position.

For many, this product looks to be a pointlessly expensive wall hook.

But, I'm willing to accept that there are some for whom it could be very useful. My concern is that if you lack the ability to pop your front wheel up to a hook then you may stuggle to generate the required force to get a bike off the Parkis. From the video alone, it looks as though you have to pull the saddle fairly hard to generate the velocity to latch the system in the down position. That would fit with a spring force designed to push the bike up.

I can't help but note that their other videos focus on the bike going up but less so on it coming down.

It appears to need power which would be a blocker from my point of view.  Also appears to have ample opportunity to trap small fingers in the track and awkward angle to bend down if you have any back issues.

what benefits would this have over using a clug?, which is both cheaper and easier to install.

Right now on Kickstarter it's saying it has €69,337 funded of a €12k goal, with 4 days to go. 

So it appears to be funded.

Which is a shame - BECAUSE THIS IS THE WORST CYCLING KICKSTARTER EVER.

The space it is saving is negligible. You have only reducred the footprint of the bike by a fraction - maybe 1/3. And you've introduced the hazard of a handlebar at eye-eight.

I have a bike storage room where I can hang up to 10 bikes vertically, on a combination of wall and ceiling hooks. Even full-sus MTB's are no problem to hang off the floor, let alone support on the rear wheel. If you can ride a bike, you can pop it onto its back wheel and hang from a wall hook.

The burn is strong with this Kickstarter.

It's a pity it didn't reach it's target as I actually like this design.

I'd buy one or two when I move house.
