KHE Bikes is one of the top BMX companies right now. They used to be very prominent in the freestyle sector of BMX, although they were doing better in Flatland. They have had a few freecoasters that have made an impact on the market (only two are here, I am searching for the rest)...

Geisha

Anyway, The second of the KHE coasters is their very recent Geisha. This is currently the most popular of the coasters. It is also the lightest that we have seen. The flatland version comes in at 18.4 oz. It uses two bearings on springs to create resistance (something that was shown first in the Poverty freecoaster), has a spindle with replaceable axles. Here is a PDF file direct from KHE describing the adjustment of slack.

	Flatland Version	Street Version	Other Options
Hub Shell	36h	36 or 48h	Gold or Brown
Spindle	Aluminum	Aluminum	None
Axle	3/8” Steel	14mm Steel	Aluminum(discontinued) and Ti
Clutch	Aluminum/Chromoly	Chromoly	None
Weight	18.4	19.8	Can get down below 17 w/ ac
Resistance	Bearing Spring	Bearing spring	None
Driver	9 or 11t	9t	None

• Cone spacer (should but up against the non drive side bearing)
• Non-Drive side bearing
• Top hat washer for slack adjustment
• Hub shell (available in Gold (36h) or Brown (48h))
• Clutch (Flatland version is shown. Street version is solid steel)
• Driver
• Washer to prevent driver binding
• Left axle stud
• Center spindle
• Ball Bearing Spring Resistance
• Right axle stud

**(not pictured are 3 spacers between #2 and #3 to adjust the gap)**

Here is how the balls get their tension:

Here is a picture of the yet to be released 6-bolt disc mountain coaster:

It will have MTB 135 mm spacing stock (though the spacers can be swapped to fit into a BMX frame), Has a 6-bolt disc adapter, a 9 tooth driver, and will be available in 32 or 36 hole drillings

Geisha Reviews:

Reverse

KHE has recently announced that they will be making a Bruce Crisman signature Freecoaster called the Reverse. It will use pretty much the same internals as the Geisha, except it will have a solid axle instead of the EAS (3-piece axle) on the current Geisha coaster.

Rollex

Their coaster before the Geisha was the Rollex hub. Supposedly the original prototypes worked extremely well, and have been working well up to this day. However, the production models had quality control issues. The materials were simply not up to par, and also, the tolerances were not tight enough.

It was, however, a very interesting design that was supposed to be very smooth and prevent side to side forces on the bearings.

You can see in this picture nearly all the parts of the hub. It uses those 5 rollers to push up and engage the up. There is also a spring on the top of the rollers to allow the mechanism to work.

This is a look at the spring on the inside of the hub, and of the hallow axle.

... and more closely

This is the clutch side of the driver.

Driver side

Here is the view of the entire mechanism. From top to bottom: Index finger; Cog/Driver; bearing; Rollers; Spring; Clutch; Thumb

And a side view

This was quite a good experiment in freecoasters, too bad it didn’t really gain ground.
