The description focuses on mechanical and electrical components for providing auxiliary power and control to a wheelchair. There is no mention of AI or ML algorithms for control, analysis, or any other function.
No.
The device is described as an add-on to provide electric propulsion to a manual wheelchair, increasing mobility for the user, rather than for a specific clinical or therapeutic purpose.
No
Explanation: The "Intended Use / Indications for Use" section explicitly states that the device "is not intended for specific clinical use, but as a support to the mobility of active manual wheelchairs' users." It describes the device as providing auxiliary power to a manual wheelchair, which is a mobility aid, not a diagnostic tool.
No
The device description clearly outlines numerous hardware components including a motor, wheel, battery, handlebar with interfaces, display, stand, battery charger, clamps, crossbeam, and connector. This is not a software-only device.
Based on the provided information, the KLICK device is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use is clearly stated as "a support to the mobility of active manual wheelchairs' users" and "to add auxiliary power to the manual wheelchair, increasing the mobility for the wheelchair's user." This relates to physical assistance and mobility, not the diagnosis of diseases or conditions using in vitro methods.
- Device Description: The description details a "TRACTION UNIT" with a motor, wheel, battery, handlebar, and connection system. These are components for providing propulsion and control to a wheelchair, not for analyzing biological samples.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), reagents, or any processes related to in vitro diagnostic testing.
Therefore, the KLICK device falls under the category of a mobility aid or powered wheelchair attachment, not an in vitro diagnostic device.
N/A
Intended Use / Indications for Use
KLICK is not intended for specific clinical use, but as a support to the mobility of active manual wheelchairs' users. It is designed to add auxiliary power to the manual wheelchair, increasing the mobility for the wheelchair's user. Therefore, bearing in mind the operating precautions described in this document, there is no need for professional, technical or aptitude requirements to operate or use a KLICK device.
KLICK devices are intended as add-on devices for wheelchairs, thus the intended user is a person with motor disability who needs of the wheelchair support for movement.
KLICK devices are medical devices designed for active, disabled wheelchair users with max 120 kg of weight. KLICK devices are designed to add an auxiliary power assist system to manual wheelchairs, quickly and easily.
The intended user is a person with motor disability who needs of the wheelchair's support for movement. Coupling the KLICK device to the wheelchair raises the front castors off the single wheel of the "traction unit" is then used for steering. The resultant 3 wheeler vehicle increase the mobility of the patient and allows him to cover up to 50km of travel range both indoor and outdoor. The system is easy to connect and disconnect.

Device Description
The KLICK 2021 device is a "TRACTION UNIT" (also called DRIVE UNIT or HUB) which is connected to the wheelchair (via a LINK SYSTEM) to provide electric propulsion to the three wheels resultant vehicle. The motor is in the front wheel (traction unit).
The handlebar contains all the interfaces with which the user can drive the vehicle.
The front castors rise off the ground and a single wheel, in the "traction unit", is used for steering.
Klick can be used both with rigid or foldable wheelchairs.
The main parts of the drive unit are as follows:
- HUB (drive or traction unit): is the aluminium frame with brushless motor, steering set and aluminium
fork, for both the steering and the traction functions - Motor: is a brushless unit with 250W nominal power for the Power variant and 1000W power for the Race and Monster variants
- Wheel: aluminium rim, 14inch diameter for Power and Race, 20inch for Monster
- Removable battery (available in 3 capacity versions: 11.6Ah, 5.8Ah, 2.9Ah)
- Handlebar with user interfaces:
- i. Throttle
- ii. Cruise control, front/reverse selection switch
- iii. Electronic brake
- iv. Left hand mechanical brake
- v. Right hand mechanical brake
- vi. Display command for ON/OFF, level selection, on/off lights (optional), on/off usb charger
- Display with driving informations, main parameters adjust.
- Stand for support the device when disconnected from the vehicle
- Battery charger is an external carriable unit (54,6V 2A) supplied by Klaxon-Mobility GmbH.
The main parts of the connection system are:
- Clamps: are always connected to the wheelchair, assembled by a Klaxon's trained specialist
- Crossbeam: is connected to the clamps and supports the connector; the crossbeam is removable for installation on foldable wheelchairs. The connector is adjusted for each application by a Klaxon's trained specialist

Dear Riccardo Colomba:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

SUBSTANTIAL EQUIVALENCE CONCLUSIONS 2.4
INDICATIONS FOR USE 2.4.1
From the indications for use point of view, referring to the two devices are deemed substantially equivalent:
- a. Both are intended as ADD ON to manual wheelchairs.
- Both the devices are designed to add electrical power to the manual wheelchair in order to ﻣﺪﻥ ﻣﻦ ﺍﻟﻤﺴﺎﺣﺔ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪﺓ ﺍﻟﻤﺘﺤﺪ reduce or eliminate (in the case of Klick) the efforts of the user.
- Both are meant to be used by active wheelchair users ပ
The Predicate device is meant to be mounted on the rear of the the Subject device is meant to be mounted on the front. This different layout of the two devices doesn't affect the neither indications for use nor the intended use, which, for both, is to be added to a manual wheelchair in order to turn it into an electrical powered device.
2.4.2 TECHNOLOGY
The main technical differences between the predicate device and the subject device are:
The mounting position: the predicate device is mounted on the castor wheels are on the ground, which leads to a high risk of roll over in case of ground unevenness; the subject device is mounted on the front of the wheelchair and the castor wheels are risen off the ground (25mm to 40mm). The safety level is higher on the subject device because of the very low risk of roll over in presence of ground uneveness.
The braking means: there are no brakes on the predicate device, whilst the subject device has doublecaliper mechanical brakes and electronic brakes. Moreover in downhill there is no mean to reduce the speed of the predicate device, whilst the subject has an automatic speed control which maintains the selected speed also in downhill.
PERFORMANCE 2.4.3
The higher performance of the subject device (15 km/h instead of 10km/h) do not affect the subject device is deemed to be safer than the predicate due to the presence of both double-caliper mechanical brakes and electronic brakes. The predicate device has no braking means.
2.4.4 CONCLUSION
Under all points of view (indications for use, technology, performance) the subject device's level of safety is not negatively affected by the differences against the predicate device.
The analysis of the indications for use, technology and performance leads to deem the subject device as safe and effective as the predicate.
