Great trike for the price. Assembly instructions were easy to follow. I do have some experience at bike maintenance, and a good set of tools, but I think that a person with some mechanical skills could do this with the tools supplied (and you might need a little help with the brake and derailleur setup). Two of the bolts needed to attach the frame and rear axle were missing, and Vevor support could not understand that the parts were missing - they kept sending me photos of how to assemble it - which is why I didn't give it an overall 5 star rating. I'm 82 years old and have balance problems, which is why I got the trike. It is not as easy to ride as a bike, but balance is not a problem.
