Comments about Sonic Boom 16 inch Boys Bike:
Bike is really good, was bought for christmas for our 6yr old who loved it becuase it looks like a 'big boy bike'.
Only downside is that the wheel was very hard to attach and we had to pull the metal fasteners to make the wheel fit on.

Assembly
Our bikes are built by industry leading manufactures and then packed into sturdy cartons. The bikes are 85% assembled, which we've found is the best way to protect your bike during transport. You will need to part assemble the bike. Allow about 1 hour to fit the wheels, slot in the handlebars (the brakes and gear are fitted for you), and fit the saddle and pedals. Instructions and a tool are supplied.
