A simple check is with the photo above.
Print it out this photo on heavy paper, then cut out around the image, also cut out the rear side windows.
The trike it's on has 20" wheels, so just hold up the photo between you and your trike, and adjust the distance so the front wheels match in size.
If any of your trike other than the bottom shows out side the image, it may be to long for the VeloKit.
If it's minor, like the big back wheel, the rear panel on the VeloKit can be cut to allow the wheel to stick out the back of the kit a bit.
If it's to long you'll have to get the VeloKit XL.

Also you'll notice the dotted lines printed on the photo, they show approximately how much the Kit can adjust up and down for head room.
Check the same way, but with some one sitting on the your trike ( w/ helmet).

The kits will fit many trikes, and I am adding to the list as time and money allow.
The mounting hardware is pretty universal, and the main problem is the size of the trike. ( length and height ) 51"/130cm from head tube to back of
rear tire. This can be stretched a bit by notching the rear body fabric.

The kit has 4 mounts:
1 off the front boom.
1 off each head tube.
1 off the rear cargo rack. (a trike must have a rear rack to mount the VeloKit)

Mounting and fitting the first time out of the box takes about 90 minutes for the average person.
Once that is done, the kit comes off the bike in a couple minutes, with the 4 mounts remaining on the trike permanently.

Also the body is standard, so it will mount to any trike that has the mounts attached.
This is handy if you own several different trikes, or if you buy a new trike, you won't have to get a new VeloKit.


One final thing: the VeloKit is designed for weather protection only ( rain, cold, sun ).
It is not a high speed fairing and should not be used at speeds above 25mph/ 40kmh.

Below is a partial list of trikes the VeloKits have already been fitted to.
As I design new hardware they become compatible with more trikes every day.
I recommend that you install fenders on all wheels,
and you must have a rear rack installed.

This is a good example of the VeloKits adaptability.
This is a 1993 EcoCycle.
That's 16 years old !!!
Most people are lucky to get a rack to fit some thing that old.
This VeloKit is mounted on a 2006 ICE QNT
Notice the custom cut out above the rear
tire, an advantage of fabric body
construction.
Some of the newer 700 C trikes are longer and will need the VeloKit XL.
It's about 12" longer than the standard kit and sells for $1200 US
