During the forward movement the motor winding (Stator) is uncoupled (by the freerun). This is not the case when moving backward, as the motor windings create a voltage causing the LED´s flashing, which is completely normal.
The R20 is a pushing device without any braking function. A drumbrake is only recommended, but not mandatory, as it always depends on the capabilities of the user and the area of application. (E.g. Environment, sloping terrain.)
The motor power will be reduced − the motor operates with a low charging level ~100 W lower.
The R20 is compatible with all wheelchair models that have a box frame and tube diameter between 22 and 28 mm. For the latest information vist the R20 webpage.

This can be seen in the docking arm matrix (please see documents in the parts manual or also documentation R20 on the web page.

Yes, this is possible by using the docking B version 29-32mm.
Yes.The docking system B covers frame tube diameters from 22-28mm due to its design (shape of the clamping parts). In addition there is a docking system B for 29-32 mm tube diameter, but the only difference is the length of the bolts.
Yes it is possible, please use docking B and choose the option EMR000146 Neon² on the orderform.
