The clutch mechanism that allows the bike to coast is broken. It requires special tools to replace, so unless you're an eager have a bike mechanic fix it for you. Tell him you need either a new freewheel or a new freehub body.
No because the bike would brake evry time so no
A freewheel in the rear hub is designed to let the bicycle coast forward without the pedals going round and round. Because of the freewheel, pedaling backwards also disconnects the pedals from the hub.
Because your pedaling too fast...
Well that happens because of 2 things:gravity and friction.When you stop pedaling it keeps going because the gravity is causing it to keep going or there is not much friction.It starts to slow down when the friction is enough.
Your dog will walk backwards on the linoleum floor because it feels cornered. Your dog may also walk backwards because they are playing.
No because it cant be said the same way backwards 1936 backwards is 6391 ex: Hannah backwards is hannaH
Deer, because 'deer' spelled backwards is 'reed'.
ANSWER:For the front wheel on most bikes, it wont matter. On The one I had, the rear axle had a specific groove for where the sprocket went and the axle wasnt interchangeable. You knew right away if It was on backwards because the chain wouldn't go on the bike. For the newer bikes, I truly don't know.
Because unless you have a hill to coast down, or a really strong tailwind, you need to pedal to provide a force that can push the bike forward.
Because any time anybody's foot is touching it, the foot is pushing it backwards.
The Schwinn 420 elliptical is available for online purchase at numerous places but I would suggest looking at Amazon first mostly because it give you options for new and used ones. Here is a link: http://www.amazon.com/s?ie=UTF8&keywords=schwinn%20420%20elliptical&rh=i%3Aaps%2Ck%3Aschwinn%20420%20elliptical&page=1.
the weight limit is usually 300 lbs because it boggs down but it will break with about 450 - 500
