I'm the guy who designed the 212. Getting the handling right was my first priority. Compare the Coleman CT200U and the 212 and you'll see how bad the CT handles. The original 212 design, (Originally the MM-B212 now the 212 PRO) uses 34mm tubing for the main frame, (mostly a design choice than a strength or durability choice), and has a headlight, CVT, front suspension, and front and rear hydraulic disc brakes. The rigid rear was used to keep costs and complexity down. The large tires with 10psi help to absorb the bumps. The second version was done for Walmart. It uses 25mm tubing, rigid front fork, rear hydraulic disc brake, and a centrifugal clutch with an automatic chain tensioner. The third version, (Mega Max 212) was done for other mass retailers and was similar to the Walmart version but has front suspension. As for the 212cc Lifan engine, Lifan rates them at 7.5hp. Their earlier 212cc engines were rated at 7.0hp but Lifan came up with a new head design and a rating of 7.5hp. We used the 7.5hp engines in all of the 212's.
Getting back to the frame design, I made it so the tooling for the rigid rear design could be simply modified for a rear suspension model to be produced later possibly for non mass-retailer businesses. However, don't hold your breath for a rear suspension model.
