Just bought a Catrike Trail...
All I can say is I love this thing, the chain was a pain in the ass though to string up.
I assembled it last night and took it out for a 5 1/2 hour maiden voyage around Calgary.
While out, I had a regular chain skip, turned out to be a stiff link, got that fixed and it broke not 10 min later... Fortunately came prepared with a chain tool and a master link, working beautifully after that.
Word of advice to anyone new to trikes... In the right gear, a trike will climb walls BUT if you're in the wrong gear and stall on a hill, park, rest a bit, and if you can't take off again, lock the brake then stand up after you've rested, rubber recumbent legs will bring you down like a limp noodle and you won't realize it in a reclining position.... I have a bruised tailbone now and bring an insulating cushion for your bottom if cold weather riding. Low mesh seat = freeze your backside off.
