The trike was stolen from the trust on Ilam Rd, Burnside, between December 17 and January 14.
It is a specialised piece of equipment for a disabled man and makes a huge difference to his daily life.
If anyone has any information that may help police reunite the trike with its owner, phone 105 and quote file 210115/3505.
Alternatively, the trike can be returned to the Laura Fergusson Brain Injury Trust at 279 Ilam Rd.
