Excellent clip! Got it, thanks. p.s. I followed Terry "UniGeezer" Peterson here.

One website specifies the schlumpf hub as 1.55 ratio but these planetary gears have 14 teeth suggesting 1.5 ratio with a 21 tooth sunwheel. A 1.5 ratio has 2 wear spots on the tire per revolution, another similar ratio could give easily give many more wear spots to prolong tire and wheel part life per power stroke/stance. I wonder if these things could be lightened up with either titanium/magnesium gears or lighter drillium versions of what they're already made out of. Keep up the innovation y'all! But wait, I don't really know how to calculate planetary gear ratios. Another video online makes it look like the gear is closer to 1.55:1 than 1.5:1.

Kris, I just saw a video about a lawyer who unicycles to work riding on sidewalks. I've an eight mile commute, (2x monthly in warmer weather a 60 mile commute). Could a geared 36" or any unicycle be safe to ride in regular urban and rural road traffic. Are there any videos you are aware of that shows the skills needed or would I be relegated to bike paths? I'm thinking with this hub I could average 16-18 mph.

No hard feelings here, Kris, for "borrowing" my video capture and edit - especially since you're one of the stars of this video. I do, however, expect some free lessons from you so that I (a uni-newbie) can go farther than 30 feet and keep from always leaning to the left. I should have started when I was much younger. Sigh...

This is great, and I will be passing it on. One recommendation: a lot of the video is of Kris riding an un-geared uni; I would prefer it if had some video of high-speed riding -- actually showing the benefit of the Schlumpf hub. Also, the narrator says it allows a uni to go up to 25 mph. The current record is 33 mph!

Plus it's a 1.5 multiplier so the math is even off. 12.5x1.5 isn't 25.

Sorry Bob! I would have contacted you if I'd known how. Anyway, thanks for grabbing this as I don't have a TV and wouldn't have seen it otherwise.

I have a 26-in direct drive unicycle. With this hub's 1:1.5 my 26 would be equivalent to a 39-in uni. Being lower to the ground than being up on top of a big 39 should be worth even more because s lower profile means less wind resistance. You also don't have to fall as far! If you calculate the price of the hub and subtract from it what you're not paying for a 39 direct drive, the price is mitigated.

I did a blog post a few months ago about different designs for geared unicycles, including the Schlumpf hubs. You can find it in the unicycling category on my blog "randomascii" on wordpress..

I read and enjoyed it, Thanks! I hadn't heard of the dual chain drive, but I had considered making one the way Huni Rex does it, I didn't know someone was already.
