Compit FAQ

There is a COMPIT system available for use with standard bikes and eBikes (pedelecs) and one that is especially for use with eBikes with a Bosch Intuvia/Nyon display.

The COMPIT system was developed for handlebar brackets with the diameters 22.2 mm, 25.4 mm and 31.8 mm.

All of the components that are included as standard are covered by a 5-year warranty from the date of purchase. SKS GERMANY provides a 6 months warranty for all of the wearing parts – especially the +COM/CHARGER battery unit.

Yes, the COMPIT smartphone holder can be ordered separately and the +COM/CHARGER battery unit can also be purchased later.

Adapters for a front light are included when you purchase the COMPIT+/POWER. Adapters for an action camera can also be ordered as an optional accessory.

The +COM/CHARGER battery unit is included with the COMPIT+/POWER.


You require a suitable cover with a special mounting device for your smartphone. Once the cover or cover adapter has been fitted to your smartphone, the smartphone is mounted by being twisted over the bayonet attachment ( in a horizontal or vertical position). The smartphone can be released by pressing the release lever and twisting the smartphone.

You need a light with a maximum light base width of 12 mm. The minimum drill hole diameter has to be 6 mm. A LUPINE SL can also be directly mounted without an adapter. The light is simply mounted on the clamping arms with the light adapter using the LUPINE mounting screws.

There is a universal adapter available that can be adhered to an existing hard cover (silicone, soft and multi-piece covers are not suitable ). The mounting is self-adhesive and should be attached to the centre of the cover if possible.

No, the adapter is only suitable for use with a hard cover. Please do not adhere the universal adapter direct to the smartphone and always use a hard cover.

Yes as the +COM/CHARGER is produced with a IP54 weather protection rating.

The system is suitable for use with all handlebars that can be combined with a front-end combination and has a clamp diameter of 22.2 mm / 25.4 mm / 31,8 mm or 35 mm. The clamp diameter has to extend over a minimum width of 70 mm.

Questions concerning the charging of the COM/UNIT and the smartphone

Charging takes place inductively ( wirelessly ) after mounting. Should you have a smartphone that does not have an inductive charging function, you will require a matching charging cable. This is also available from SKS (Lightning, Micro USB and Type C USB).


This technology makes it possible to transmit energy over short distances by means of electromagnetic induction ( inductive charging ). The +COM/CHARGER that is certified with this standard is able to charge your smartphone wirelessly on the basis of the Qi standard.

A use of approx. 10 hours with full capacity is possible if the smartphone battery and the +COM/CHARGER are fully charged

A completely empty +COM/CHARGER takes approx. 6 hours to recharge, depending on the charger.

Yes, but the charging of the smartphone is restricted during permanent navigation. The battery status of the +COM/CHARGER should be at least 50% so that the smartphone can be adequately supported when navigating.

Yes, that is theoretically possible but the output current is so low (<0.5 A) that it is not possible to charge the smartphone and use a navigation app at the same time.

No, the charging of the +COM/CHARGER only requires a small amount of power so that this does not have an effect on the range of the eBike.

No, the smartphone always has priority. The +COM/CHARGER is only charged after the smartphone has been fully charged

With all of the manufacturers in theory but this is subject to the following requirements: the handlebars need to have a diameter of 22.2 mm, 25.4 mm, 31.8 mm or 35 mm and the front-end combination width or the front-end combination cap has to be max. 49 mm. The board computer has to be equipped with a micro USB current outlet (can also be altered using an adapter). Another requirement is that the eBike drive system has to have a 5V-15V outlet and the current has to be a minimum 0.5 A.

Ensure that the +COM/CHARGER is switched on and is sufficiently charged and that the cable adapter is correctly positioned.

No, they can’t. The COMPIT system holds the smartphone reliably and it’s low in vibration. Therefore it’s really easy to use the smartphone and to read what is indicated on the display. Furthermore, the stable and micro-steamed COMPIT mount prevents a damage of the sensitive electronic components of the smartphone.

Yes, it does. You can simultaneously charge the +COM/CHARGER with frame contact or with a USB-Port of the E-Bike and discharge it by charging your mobile device itself (with cable or wireless).
