Review: Very good, reliable bike - I bought the black frp mb40. Shipping is great. It only took 24 hours to ship and only a week to get it. It looks pretty cool. The frp mb40 is really, really small. I am 4'10" and I sit comfortably on it. So the bike might be for people 4'10" and shorter. The bike runs great, except the handlebars vibrate like crazy. It started on the 3rd pull, which is typical for a frp mini bike. I weigh about the limit for the bike and it still runs great. The engine does get a bit hot, though. You have to watch where you put your legs because you can feel the heat coming off of the engine. You just have to put together the handlebars, front tire, front fender, and seat. The seat was a little bit of a pain to get on. That's the only thing I needed help with building this bike. You just have to fill the tires with air, put oil and gas in the separate compartments and it's ready to go. I only had it for a week and rode it three times so I will update this review next year.
Review: Great Value and super fun - Our 11 year old son loves it. It has a decent top speed, good acceleration. it was super easy to put together and has no issue firing it up. Little tricky to get oil in, but came ready besides gas. small gas tank so if they ride all day they'll need to fill up, but overall great value for the money. And you can get replacement parts if needed instead of just having to throw the whole thing for scrap, so with good TLC should last. Kid can start it up easy, too, but the first few times learning how to use the choke might be a good lesson.
