It's probably the bottom bracket bearing. Exercise bikes typically have really, really cheap bearings in them. I have the same problem on my Horizon M4 with a lot of bearing chatter when doing standing high resistance.

How do i adjust the tension on a ActionC100 exercise bike

I just fixed a C100with the same problem today as follows:
Take off the pedals, seat pole, and side panels ( 3 long screws on the top and 4 short screws on the bottom then push out [from the inside] the pedal shaft outlet covers and gently take the covers off by turning the pedal shaft). You'll see the cable to the wheel and secure it to the lower chassis rail by tape or a cable tie, then undo the lock nut on the cable end and extend the screwed sleeve by 10 mm. You'll then see that pulling and releasing the outer cable will loosen and tighten the magnetic brake more smoothly. Good Luck, Andy

Specialized hard rock freewheeling, like a transmission in neutral.

It sounds like the freewheel is stuck open, if its been rebuilt recently it could be that the grease is too thick or there is too much of it. If it's the original and old, it is most likely that its just sized and needs to be replaced by a professional bike mechanic.

The pedals on my Nordic Track SL700 turn completely free. I think I need to replace the crank assembly but cannot seem to get into it. Is this bike worth the price of a new crank assembly part?

Dear Sir:

Please do the following:

Use aflat screwdriver to unseat the tabs that hold the front top cover in place.This will expose the flywheel and pedal arm connection points. Rotate theflywheel by hand and determine whether lubrication will accomplish the repairs.If the bearings are exposed, use a grease gun with an extension nozzle and lubricateboth bearings with lithium grease. If the bearings are damaged or sealed,proceed to the next step.2
Removethe front and side covers on the main frame. Hold the flywheel with one handand use a box wrench to loosen the bolts that secure the pedal arms at eachside of the flywheel. Pull the arms away from the flywheel and remove thebearings from each side.3
Test thebearings as before. Lubricate exposed bearings with lithium grease andreinstall them. Sealed bearings must be replaced. Reattach the pedal arms tothe flywheel. Replace the main frame covers and front top cover to complete therepairs.sincerely. God bless you.

I was pedaling my bike home last night when suddenly my pedaling didnt rotate the rear wheel anymore. the chains are still on the gears and will still change speeds, but it freewheels. i got it to catch...

You need to replace your freewheel (about $20). I'd advise taking rear wheel to a repair shop, as you'll need a freewheel removal tool (they retail at about $25) and most shops will replace it for free (with their tool) if you buy the part there.
If you pick up the tool, here's the instructions:

Just installed the schwinn hitch rack 3 on the hitch of our vehicle. How to we fasten bicycles on rack? men'a AND women's bikes.

For the ladies model you need an adapter bar to make it like a mans model. , mens, you just set arms on the bike's top bar and bungee it or if it has straps use them. Make sure that your pedals do not scratch your trunk by either buying foam pedal blocks or wrap and tape them. Put the womans bike on first.

Son's can pedal 12" bike

Yes, something isn't turning freely. It's either the front wheel, the back wheel, or the pedals and chain. Lift the bike off the ground and turn the front wheel by hand. If it doesn't turn very freely, it could be the hand-brake is dragging or the hub bearing is too tight. Try the back wheel in both directions. It should move freely in the forward direction. When rolling it backwards it is normal for the pedals to move too if this bike has a coaster brake (that is the kind of brake that is applied by pushing the pedals backwards.) It the back wheel moves forward freely, but backwards is a problem, then try the pedals by hand with the rear wheel off the ground. If this doesn't turn freely, the pedal crank bearing (a.k.a. bottom bracket) is too tight. Once you have identified the problem take it back to where you got it. It should be easy to fix, or they should replace it.

I just bought an InStep® Joyrider Bicycle Trailer and the photo's are not very good. When attached is the bike trailer hitch supposed to attach perpedicular to the bike and the spring bends to 90 deg....

The hitch part that fastens to your bike rear axle has 3 pieces, a dimpled washer which goes on first then the hitch plate and a pin that holds the trailer to the hitch. Take off the axle nut (15 mm wrench) install the dimpled washer it goes on with the 90 deg tang facing the bike wheel and in the channel so it can't rotate. Then put the hitch plate on, mine faced down for the correct height, line up the dimpled washer with the bumps on the hitch plate to locate it properly. reinstall the wheel nut and be sure to align the wheel so it runs straight and true (I oopsed on this the first time) then attach the trailer, it is a 90 deg hook-up then you simply put the the pin in and you are good to go. The unique hook-up makes it so smooth and dampened that you don't even know it's behind you. We really love ours!
