Don't really understand your question. A bicycle while freewheeling AKA coasting isn't receiving any energy input from the rider. W/o energy input there's really not much point in calculating efficency.
On a flat surface the bike will simply roll to a stop as air drag, bearing losses, and rolling resistance in the tires slowly use up all of the momentum or kinetic energy that was in the bike + rider at the moment the rider stopped pedalling.
If it's at a downhill slope, then gravity will try to drag the bike forward/down, if the frward vector of gravity is bigger than the bearing losses, rolling resistance etc etc.
On a singl speed bike while pedalling, the freewheel isn't moving WRT the hub, so the issue becomes moot. What you're left with is the efficiency of a chain drive( which is high, 98% or so). And for the whole vehicle you then have to subtract bearing losses, rolling resistance ASO.
If you include the rider you might want to consider the losses in turning food(chemical energy) into kinetic energ(i.e. the bike moving forward). And with that approach stuff like bearing losses aren't even on the chart and can be ignored.
Efficiency bar refers to a measure of how well someone performs their job responsibilities in a timely and effective manner. It is often used to evaluate productivity and effectiveness in the workplace, with higher efficiency bars indicating better performance.
Someone at a coin shop will evaluate your coin, but they will offer you what they want to pay for it.
There are really too many to list then here. Focus, Nishiki, Bianchi, Cannondale, Schwinn, Trek, Mongoose....
The No Seat Bicycles Law (CVC 21204) requires all bicycles to be equipped with a permanent and regular seat. Riding a bicycle without a seat in California is a violation of this law.

Reviews for Trek Bicycles can be found on Yelp, on the Trek Bicycles website, product pages on Amazon and on various Facebook sites. Amazon has the greatest number and variety of reviews, so this would be a good place to start.
A person can purchase tires and wheels for bicycles at many locations. Bike stores and general merchandise stores carry all types of parts for bicycles.

Oh, plenty. amazon.com have bikes, cambriabike.com have them, There's Jenson, someone called bikesdirect etc etc.
This depends on whether one is looking for bicycles or motorcycles, both of which KTM produces. KTM bicycles are available at many bicycle shops in South Africa, Australia, and Europe. KTM motorcycles are available at motorcycle dealers throughout the world. They have a dealer search function for motorcycles on their website, but there appears to be no centralized search function for dealers that carry their bicycles.
check their color
My friend said the answer is "purple, because bicycles don't wear sleeves!" and i do not get it! someone please explain??
