Most of the METAL PARTS appear to be relatively beefy in construction as far as the frame and gears. The parts for the basket are usable at best. Fenders and chain guard are very tinny, light construction and easily bendable, would like thicker metal to have been used on those parts. Instruction Manual for Assembly looks nice but barely usable to actually assemble the bike. It'll give you an idea of what parts you are looking for, but how to connect them correctly to each other is often lost and boils down to YOU making the right choice. Tools included are adequate. I found videos on YouTube for Subject of MoonCool Tricycle Assembly far more informative than the Instruction Manual was. The ONE Serious Flaw In My Opinion is how the handlebars are connected to the downtube to the front tire. There is no real physical connection between the handlebars and front wheel. There is a long screw that goes down into the tube connected to the front tire. At the end of that long screw is a metal plug with the top cut at an angle, at the bottom of the handlebar the tube is also cut at an angle. When you tighten the screw it draws up that plug, when the two angled cuts meet, they push against the inside of the tube connected to the front tire. So it creates FRICTION to stay connected, not a physical connection like a bolt etc. When I first tried to ride it the screw had not drawn that plug up to get a tight enough fit, so while riding I hit a small bump and suddenly my front tire was pointing left and the handlebars still pointed straight ahead. Thought I was riding a BULL at a Rodeo for a minute or so. I wish they had a more Phyiscal Connection as I'm betting a hard enough bump or even a quick movement will once again put the alignment between where the handlebars are pointed and where the tire is will not always be accurate. Because of that I WILL WEAR A HELMET when riding this bike, at more than walking speed, I do not TRUST the connection.
