My advice to everyone just getting started is always the same, don't scrimp on brakes, wheels, or tires. MBs have the ability to go much faster than many bikes are designed for. Hitting a storm sewer drain at 25-30mph can ruin things that a pedal bike at 12 mph would barely feel. Most sane MB riders want more than just a rear wheel coaster brake. They tend to lock up, skidding the bike into a fall, and crashing into a car or truck, while bad, is better than skidding under one. The other problem with coaster brakes is they are chain activated. A derailed or broken chain means no brakes at all, and that could spell disaster for the rider.
