Mine is an old Gary Fisher Aquila Mountain bike.. Mine has been a very interesting installation so far due to a number of issues with the design of the bike.

If you check out the Rotten Orange Gary Fisher build in the photo section, theres a whole thread about it with lots of photos. Here's a link:

For most bikes, this shifter kit is a pretty simple installation, but you can read about how i'm solving some issues that I came across solely due to the way my bike was built.

Datz and I both got the Sick Bike Parts Shifter Kit from Welcome to Sick Bike Parts and it has been a lot of fun to ride. At 200 dollars they are not making a lot on these kits and it would be very expensive to try to reproduce it without free use of a full machine shop. Then you still have to get the quality parts to make it all go and the design Jim and Paul worked out.These guys are the real deal when it comes to customer service and quality product.

this seems like a good plan, but cost is a bit high dontcha think? also, how exactly does this work????

from looking at some of the vids on youtube, it looks like the jackshaft rides on the same sprocket as the bike chain. is this right? wouldnt it make it impossible to pedal???

The kit includes a front freewheel which allows you to pedal the bike but once the engine starts you no longer have to pedal, well you can if you want but you don't have to. Here is a link to a video that explains it.

Well there is a little more than that. There are 86 individual items that make up the kit including the hardware, if you remove the hardware there are 23 major components.
