TKS snowbike proto #2!

[FrozenMOTO]

frozenmoto -I'd be interested in what you are claiming that is different to this patent.

Its similar but it does not form a parallelogram and therefor the track goes under tension when the suspension works, a critical part of are patent. Also with are system there is an upper shock controlling the rear of the track to contour to the ground on uneven terrain, both of these key facts are critical for the suspension to operate correctly.

The patent shown only similarity's are that the rail breaks, sort of, there second one is not even a rail but a frame with two hyfax like things, one on angle and one normal.

We also use a hub for the driver and not a shaft, this is critical as the bearings on the shaft they use would fail quickly and be non effective in the long run.

The do manage to make the front and rear arms parallel, but the failed to make the top and bottom parallel as well as they placed the very rear most idler behind the rear arm pivot and we figured our a way to make the pivot and idler mount one in the same.

After looking over there design I am assuming it never became a reality as the design, while it looks functional, would not hold up over time.

That is a very interesting design though! Thanks for bringing it up!

proto #3!

ok so I havent got the ski done yet but I recut the tunnel sides, rebent the rails, rebuilt the skid frame, relocated the brake claiper and remounted the skid pivot point. how does it look now, it works waaaaaayyy better on the dirt now, but no more pulling the front tire up

So did you get rid of the stock bike shock.

I really think your design is promising as it looks to solve some problems some other kits have.

I didnt mean ANYTHING by the patent thing it is just something to look into.

Good luck and nice work!

It still uses the stock shock just cranked up a bit, I really appreciate the advice on the patent stuff actually! thanks

Sweet, that was the part that I liked about it, I think it will do well once you get all the bugs worked out.

the issue with patents on this kind of bike modification is that the evolution of the product happens faster than the patents can be secured.
So if the company responds to customer demands with product improvements you quickly leave the net of patent protection behind and soon you would need three patent attorney's and one good welder to build the product...............about 3 years behind the market.

Make the best product you can as fast as you can to catch the available market and keep improving the product.

Looks pretty good….I'll bet you are excited to try it out in some more snow. Does it have the ski control that you were looking for?
