F.A.Q.

The stem A-HEAD, which doesn´t allow the user to set the height of the handle-bars, is fitted to scooters as standard. However, under the stem, there are four 10-millimetre distance rings after the removal of which it is possible to lower shaft height by 40 mm most.
The possiblity to adjust the handlebars to a different height can be solved by ordering the stem Speedlifter classic or Speedlifter Twist. The two versions of the stem enable the users to set the height in the extension of 0 – 100 mm. With an improved version Twist, you also can turn the handle-bars by 90° to the left or to the right. This solution will help you to make the structure size smaller for transport or storage without any limitation of riding qualities.

Yes. You will find instructions for scooter kickstand assembly on our sites.

The front PVC mudguard on our scooters is fit so low because the position opposite the front wheel is different at a scooter rider and at a cyclist. You can trust us that this placement version has been tested and it is workable.

The rearguard for the model KOSTKA HILL hasn´t been solved yet because we are still looking for an appropriate type. However, the basic version of this scooter type already has a preparation for an additional assembly of a rearguard.

It is possible to fit a child seat BOBIKE to every our scooter, except for the types KOSTKA City and KOSTKA Racer.

Yes, the trasnport of scooters on a roof holder is possible but the holder must be for example in the variant ProRide 591 by Swedish firm THULE because the holder must fix the angle slope of the scooter crossbar tube safely.

Recommended tire pressure is stated on each cycle tyre by the producer and it is different at each producer and each size of wheel.

Scooters are mass-produced so constructions adjustments by a client´s request are realized only exceptionally. In such cases, a prior discussion about the possibilities of construction adjustment realization is necessary.

However, here are several generally true principles:
- scooters with a 20“ or 16“ front wheel are more suitable for towns and shorter tracks. They are well operated and they have a little bigger span of deck (65–70 mm).
- Scooters with a 26“ or 28“ front wheel are more suitable for long ways and fast ride. The large front wheel keeps traces very well, partially at the expense of controllability.
