What brand/model trike? Is it an adult non-recumbent (granny) trike or a recumbent trike? Decent quality recumbent trikes are not heavier than a regular cheap bike purchased at some place like Walmart. Catrike makes a high-seating Catrike Villager which weighs 34 pounds. It is still tough to lift any recumbent trike not because of the weight but because it is not compact. If you have a garage workshop, it is possible to rig up an inexpensive trike lift using a combination of a standard bike lift and a gambrell and pulley hoist . The bike lift has provision for lifting at two points but the gambrell and pulley hoist will lift the two wheels at the same time when hooked to one half of the bike lift. Harbor Freight Tool has the bike lift for $8 and the hoist for $16. Takes a little ingenuity to combine them and you also need to keep the trike from swinging side to side but raising it with the lift and settling the frame on a fixed object like a stack of milk crates would do the job.
