2.6.3 Travelling using the e-fix wheels in motorised mode

The wheels of the e-fix must be engaged for motorised operation.

•

Turn the coupling ring [7] on the left-hand wheel towards the front (L), turn the 
right-hand wheel towards the rear (R) to the stop; 

the release mechanism [6] must 

not, under any circumstances, be pressed in the process. 

A green mark is now vis-

ible in the viewing panel [5].

•

Switch on the system (see chapter 5.2.1). The e-fix is now again ready for motorised 
operation.

When travelling downhill, power is fed back into the battery pack 

from the drive wheels to increase the range. If you are travelling 

downhill with a fully charged or almost fully charged battery pack 

and the battery pack cannot tak

e up any more power, this is indic-

ated by a warning in the control unit display (see table in chapter 

6). 

If power continues to be fed into the battery pack, the elec-

tronic system automatically reduces the speed by 50 percent. 

If power consumption increases (if, for example you are travelling 

on level ground or uphill), the e-fix can accelerate to the selected 

maximum speed. 

As soon as the charging process has finished, this behaviour can 

also occur for a short time when travelling on level ground.

The e-fix cannot be pushed manually in motorised operation.

The e-fix must only be used at temperatures between -25 °C and 

+50 °C. Therefore, do not expose the e-fix to any heat sources (such 

as intense sunlight) as this may cause surfaces to reach high tem-

peratures.

When not in use, do not expose the e-fix to strong sunlight for 

long periods of time. This could cause the motor to heat up and, in 

extreme cases, prevent it from operating at full power. Plastic parts 

also age quicker under intense sunlight.

2.6.4 Range

For every e-fix user, the range of the system is one of the areas of greatest interest. In 
general, it is possible to say that this is roughly 15 km. These are ideal values and relate 
to flat, paved terrain. Deviations may occur due to topographical conditions, the ambient 
temperature, the road surface, the tyre pressure of the front wheels, the frame geometry, 
the weight of the wheelchair, the maximum occupant mass and the size of the wheels  
(22 or 24 inch).

For reasons of safety, the drive wheels must only be disengaged from motorised mode and set to push mode 

while stationary and on a flat surface. The drive wheel must be load-free when being disengaged. To do so, 

switch off the e-fix at the control unit. Actuating the clutch with a load or while travelling can damage the 

internal mechanics and is therefore not covered by the warranty.

Disengaging on an incline can lead to a dangerous situation as the e-fix either switches directly or subsequently 

to freewheeling mode and, in the worst case, could therefore start moving in an uncontrolled manner, i.e. it 

could rotate and/or roll downhill. Disengagement should only be performed on an incline in case of emergency 

and only if an accompanying person is present and capable of securing the wheelchair manually and by using the 

wheelchair parking brakes.
