If the user has difficulties using their hands, the handles are very important and make sure that the user can bike comfortably. The handles provide more grip and allow the user to steer the trike normally, even with minimal mobility.
The following two options are available:
The quad-grip crescent offers the user support at the wrist. Their hands remain fixed throughout the movement, and they can fully focus on cycling instead of worrying their hands might slip off the handle.
The quad-grip BerkelBike provides the user with additional hand stabilization. Again, the hand is fixated at the wrist and it can comfortably rest on the grip from the wrist all the way down to the fingers.
