Questions about Kokua Jumper

Yes

The brake is not included with the product. We can however offer you this one which is compatible: LIKEaBIKE Bridging Brake Kit

No, it's partially disassembled, but I'm not a craftswoman and I got it done in 20'.

I have car valves mounted and there is little space at the valve because of the small wheels. Therefore, either pump at the petrol station (usually with an attachment that takes up little space) or with a hand pump with a small attachment that you can screw onto the valve. I always use Lezyne Digital Pressure Over Floor myself.

Correction: Unfortunately, we are not able to procure spare parts, but these can be requested at the following link: xtramobil.ch/contact/ +41 44 867 15 25 mailbox@xtramobil.ch Unfortunately, this is not offered by the manufacturer itself, sorry.

According to your description, something seems to have been mounted incorrectly. When correctly mounted, the wheels sit like on a real bicycle. Apart from the fact that they turn, they have no play.

Unfortunately, we are unable to procure these, but they can be purchased here: https://www.xtramobil.ch/kontakt/ +41 44 867 15 25 mailbox@xtramobil.ch
