I'm getting myself into this whole small steps of kindness thing and I've been helping my neighbor (he's 76 and still strong) look into bolt-on trike kits for his 1999 Honda Rebel 250. He doesn't know much about surfing the web now so I'm here to the rescue. Anyway, he says he wants something safe, simple, and ideally not over $3,000. Are there kits you can recommend for this bike that are easy to work with? Thanks!
