I just started assembling this bike, and the posts that protrude from the center of the wheel are obviously supposed to fit onto the bottom of the fork. Problem is, both posts will not fit to the fork at the same time, as the fork is about 1/8 of an inch too narrow. The fork is not flexible at all, so you can muscle it open to force it over the wheel posts. Any suggestions??

Place bike on center stand.
Jack the front of the bike to raise the front wheel off the ground. Be careful!!!
Remove the front wheel.
Remove the front fender and cross brace.
Disconnect the brake calipers from the forks.
Remove the air connections from the fork tops.
Loosen the fork leg clamp bolts on the triple tree.
Slide each leg out of the bike. Twisting while pulling often helps.
This can also be done without removing the front wheel but you will have to elevate the front of the bike another foot or so - just disconnect the air fittings and brake calipers, loosen the clamp bolts and drop the whole front assembly.
It is the rear freewheel assembly causing the problem. if is fixable, but you have to be good with tools, the bicycle shop and the electric bike shop both said they couldn't fix it, but is is doable. 1. you need a special bmx tool that fits that back wheel, your local bike shop should have it in stock. 2. you need to remove the freewheel sprocket and disgard it along with the the bearings (make sure to unscrew the razor chain sprocket from the freewheel assembly and secure it for reuse). 3. either purchase a new freewheel sprocket for bmx wheel or remove one from a old bike (again you will a special tool for that). 4. screw the razor chair sprocket onto the new BMX sprocket (it goes on with the same 4 original screws, right over the sprockets. 5. Screw the freewheel back onto the rim now. tada its fixed.
The chassis is locked by the seat or bassinet unit clicking down onto the black prongs that stick up from the central hubs. It would be mechanically impossible for the front wheel assembly to swing back if the seat was fully engaged into the hub as it has a large plastic block that fits into the hubs to lock them. Remove the seat check for any obvious damage, spray some silicone spray on the prongs and the square white lock buttons. Wipe of excess with a paper towel than try to fit seat again.
If you're talking about the washers which can screw in and out you don't take them off. They hold the ball-bearings, that the axle turns on, in place. If you have moved them you should adjust them so that when you hold the wheel by the axle at each side the weight of the valve, for pumping the wheel, moves to the bottom i.e. next the ground. Any tighter is too tight any looser is too loose. You need to pull he forks of the bike frame slightly apart to get the wheel to fit between them.
If you're talking about washers that can pull off rather than screw off they can be taken off and put on the axle outside the forks next the nuts which hold the wheel on.
WOW!!!WHAT A JOKE!MY KID SAVED $470 AND PURCHASED HIS MX 650 ONLY TO HAVE THE REAR FREEWHEEL BREAK THE FIRST WEEK RIDING IT.NND BY SEEING ALOT OF THE SAME PROBLEMWITH EVERYONE ELSE.RAZOR SHOULD' VE AT LEAST PUT A HEAVYDUTY ONE IN IT.OK PEOPLE LETS FIGURE IT OUT IF ANY ONE KNOWS AGOOD BEARING COMPANY,POST IT.MY KIDS BUMMED HE CANT RIDE IT
Most training wheel kits come with directions in the kit. Do one side of the bike at a time. Start with the left side and when tightening the nut back up make sure the rear wheel is still centered in the fork . When you do the right side it is the same but you have to make sure the chain stays in adjustment as well as the wheel being centered. Usually you have to remove the nut on the side that you are working on. The kit should come with a little bar with a hole in it that fits over the bolt that you just removed the nut from. Make sure that the flat side faces out and the protrusions on the bar fit into the slots on the fork. Next mount the bar with the training wheels on the bike over the first bar. Put the washer supplied in the kit over that and then screw the nut back on. Pay attention to the wheel being centered and the chain being tight enough not to slip off the crank when pedalling. Make sure you get the proper size for the bicycle. There is a video here that explains it http://www.ehow.com/video_4974885_put-trining-wheels-bike.html
