Mobiky Genius problem
I just traded a couple power tools for one of these in fairly neglected condition. The biggest problem is the seatpost is stuck on the lowest third and will not slide through the frame. Anyone else had this issue with the Mobiky Genius and what did you do to remedy it? I do see a circular cover on the bottom side that appears to have two flat edges. Is that removable to maybe be able to better seep penetrating oil in? I really want to fix this and do it without damaging it. It had 4 broken spokes and a disintegrating rubber seal on the rear Sturmey hub. One broken spoke in front. Otherwise it appears to be in good shape other than a few scratches. Any suggestion on freeing the seatpost and does anyone have an exploded parts diagram for a Sturmey Archer SRB3 3 speed rear hub and drum brake assembly?

Seatpost is now free after letting oil drip into it, heating lightly with a hair dryer and careful prying underneath with a narrow putty knife to get it started. She moves as she should now after I kept moving the post up and down and adding lubricant to flush all the debris..
Now to get the service manual for the Sturmey Archer SRB-3. On the drum brake side, I notice little bits and chunks falling out of the recessed area under the black cover plate. They seem to be orangish or yellow in color. Is this a seal of some sort or actual part of the pad or shoe? Does this have an exposed brake pad? If so, .would a hardware store have a work around maybe? The broken spokes I will have to make. I'll remove one from each wheel and copy them. Since all the broken ones on the rear are on the non drive side, they will be the same. And of course the fronts will all be the same. My bud has a spoke threader.
And yet one more question for Mobiky Genius owners. When the bike is unfolded, do you unthread the stay tube so it is tight in it's slot? I notice if I do this, there is no slopping or sagging of the frame when I pick it up by the seat. Should there be a little play or no? I can always loosen it by threading it in before folding. Takes only 3 or 4 turns. I just wanna know if this will damage the frame before riding it. The onlinr manual is vague about how to set the stay tube.

Hi welcome.
Could you post some photos. Not had much experience of mobikey. Seems an underrated bike. Might be something generic that the forums could suggest or advice.

They apparent;ly went to A Shimano Hub wheel Now.

I love how fast he unfolds such a complex machine. Just do these 64 things and go!

Hi Anyone still rides the Mobiky 20”?
I have trouble with the wheels they are oval
The dirt guard - My legs and back are a mess after riding in the rain. I can see that the seals will get worn and I will need a neew chain at some point. When it folds the moveable pin twist and wonīt get into the holder and then it canīt fold.
Is it possible to use a wheels from somewhere else?

I ride the mobiky 12". i don't really know about the wheel but for the tubes i have used multiple times from amazon the one that fits with kids bike of that size. And for the mud guard, i am using one from decathlon with nylon strap. It has worked me perfectly.
