Installing a mid bottom bracket is very simple. All you do is tap both bearings into both side of the frame evenly, they do not have threads or anything like that its just simple pressure, don't hit it to hard though because you could crush the bearings.

On the most common bicycles the bottom bracket is the bearing assembly that the crank arms and the pedals turn in.

What type of bmx is the United Recruit RN1 2010 BMX Bike?

It's a BMX racing bike for beginners. What we would call a "Junior" size (pre-teen). It's a strange mix of entry level and high end. For example, it has a hi-ten steel frame, plastic pedals and unsealed hubs, yet it has a sealed bottom bracket and a Cro-Mo three piece crank. It's a small bike as it has only a 19 3/4" top tube and an "upside down" style handlebar stem.
