Absolutely beautiful design and fabrication skills!! Might I suggest a better shock? Something with more adjustability?
GEN II, our home built snowbike project
- Thread starter swedenturbo
- Start date
You might be right that our Fox2 shocks hasn't sufficient adjustability.
For that reason we have mounted aditional dual pressure kit from Hygear.
Hopefully they will give the adjustability as required.

BEAUTIFUL WORK! Im not a fan of the snow bikes but I dig this! I cant believe you cut that track with a cut off wheel. Vertical bandsaws work great for that.
All I can say is WOW! I have been in aerospace fabrication and maintenance business for many years and I am very impressed with your design and fabrication skills. Hopefully your innovative design efforts will help to take the entire snowbike breed to the next level.
Well done! :wine:

Thanks for all the positive comments on our build.
First test assembly of suspension.
It may look tall standing on the workbench without track but in fact it is just 40-50 mm taller than our previous build.
Tunnel is shorter than the bogie and will have a snow flap in rear.

very nice:whoo:
Track mounted
Some comparison pics with our previous build.
The only part that is not optimal is the MXZ rails. It's 9 centimeters (roughly 4") between the tip of the rails and the drive wheels. Redrill and move rails forward will result in a steeper attack angle.
The biggest problem is not about the risk of stab, that could be solved with anti-stab wheels. Rather, it is that the track that doesn't have support from the rails . This increases the angle of attack in this area.
Put my Nytro Mtx rails in front. Have flatter bend, you can get the tip closer to the drive wheels. Should work out really well I think. After some test runs I will probably switch to these rails instead.
Put the uncompleted track kit on a simple scale, ie a margin of error.
50.5 kg
4 kg of other parts that are not mounted on the kit. Also have to add another half of a chain at 0.7 kg. Total weight should be in round 55.5-56 kg or 122,3 lbs. That seems to be pretty good for a LT with 59 mm lugs.

A lot of details on the turbo kit must be adapted and redone as the new track kit has some design differences from my previous kit.
The pipe to the plenum must be altered because of new location of the brake disc.
Because the tubular frame is 10 cm shorter, connection to intercooler must be modified.
Gets tight but it should work.
Will cut off a bit of the outlet from the turbo so the rubber bend will fit.
Made previously a set of ski mounts that was a straight off copy of Timbersleds.
After a ride in mountains we saw a tendency to bending/flexing. Not due to poor design but most likely because it was used fairly short time after welding. Aluminium should rest about one month at room temperature to regain its strength after welding, at least that's what we've heard.
Well worth thinking about for those of you who weld your bogie rails!
Testing a different design that does not require welding.
In addition, a sleeker and more modern design, very similar as UFO:s ;-)
8 mm water-cut aluminum panels.
Chamfered edges. Has no practical significance but looks good.
Milled the edges with a router mounted under an old saw table.
The mill head has a ball bearing that rolls on the edge.
Powder-coated aluminum panels.
Machined spacer sleeves for axle.
M8 stainless steel countersunk screws

Love your rear suspension, can you post some details about the range of motion and it dynamics.
Test assembling gears and chains
Carbon fiber is a little fancier?
Testing the fit of the water-cut carbon fiber chain case cover.
The real thing and not just a sticker. :face-icon-small-win
Tight fit with very little adjustments.
Glued plugs carbon fiber tube with epoxy glue
Made a plastic cover at the bottom of the chain case
First test ride, awsome!
Feels light, smooth and nimble in powder.
On trail it was a bit too hard. Have to try out some different damper settings. 100 psi in the rear shock proved too much.
With a little more time and testing will probably get it even better!
Did not have time to mount TCV valve so I have run the same boost as last year: 0.5 bar. Despite low compession piston I didn't feel any difference in low rpm and NO LAG. It charging surprisingly early.
For next weekend hopefully I'll get the valve in place and raise the boost slightly. Should provide an additional 10-12 hp.
Here's a short video from my buddys bike.

Incredible fabrication skills and detail! I can't wait to see the finished result and see video if it in action.
Makes me proud of my heritage. You svedes are very talented!
Great job on the bike and the video! And your English is excellent. :face-icon-small-hap

Simply amazing, 99% of us dream of having that kind of design and fab skill!
So, how much did it cost??? :face-icon-small-sho:face-icon-small-sho:face-icon-small-sho

Very nice work. Would love to see it in action.
