This bicycle was extremely easy to put together. Most of the difficult part we’re already assembled so it took me 25min. to screw on the frame to the base, handle bar, pedals and seat. It makes minimal sound when the wheel is spinning, my 7 year old son likes a lot. I appreciate the emergency push button for quick stop. The display is helpful and you can also flip it to gold a tablet or a phone, The bike does not take much room at all, tilt to roll and move around. The seat is okay has some cushion. Overall very nice.
