The wheel was delivered pre-assembled within 2 days. Set only saddle and handlebar, support wheels mount and fasten basket. All in all 1/2 hour working and ready. Unfortunately, the Bowden cable of the front brake was bent and the rubber coating torn at the site. With duct tape but that was quickly patched. Concerns I have with the brake lever, which is made entirely of plastic and makes a fragile impression. If the training wheels are off until times I expect problems here. Otherwise, a good bike to start at an acceptable price.
