Riding a push-bike up the sides of buildings

Without going into great details for the reasons behind it, people in The City travel everywhere by bicycle.

There are no stairs or lifts (elevators) in high rise buildings and no safe parking spaces for bikes at ground level.

To reach their home or office in a high-rise building, cyclists must cycle up the vertical face of the building and enter through a window.

I'm looking for a realistic way to implement this. Whatever the solution, it must not involve outside help, either human, animal or mechanical power. The bike rider must use only pedal-power and stay on the bike at all times while it is moving.

Here's what I have so far. The bike is only slightly modified. It has a spool mounted on the rear wheel that uses friction to climb the rope. It also has 'spikes' sticking out of the hubs of each wheel (these are described below).

The building has a rope hanging down and the cyclist winds it once around the spool. The rider then slots the spikes which are extensions of front and rear axles into two vertical slotted rails that extend up the whole building.

The cyclist then rides up the side of the building to the required height.

Question

Are there any theoretical or engineering factors that make this setup impossible? Note: I am not asking whether the idea is sensible.

What, if anything, is bad about my design from an engineering point of view and (without investing in a lot of extra machinery) what could be improved?
