Have you broken one of these SX-RK3's yet? I'm putting one on a 48v BBSHD setup that I'm going to program to bring the power on slowly. I'm hoping it should be close to bulletproof.

There no information about SX-RK5 on the official site. Can you share link for this IGH?

Hello "Urban Cargo Bikes" !
I've seen you've been posting a couple of videos on the IGH SX RK3 I'm actually looking for one, any idea where I could buy or order one ??! I'm Montreal base too ! Thanks

[marcofecteau]

Salut, très bon video! Ou est ta boutique? Selon ton experience, quelle est la puissance maximale que ces moyeux encaissent?

HI I'm in the Griffin town area as well, I may need a wheelbuilder/ advice for a hub Drive tandem bike. Thanks.

Could you tell me how many MM length spokes you have on that 3 speed bike because I have the same bike and was thinking about converting mine to the sturmey archer RSX-RK3

I already converted one of my 26" fatbikes, since I liked it on my 26" I was thinking about converting my 20" bike as well as you can see o my profile pix Ultra 1000

May I suggest to run DUAL batterys on your bike I did both of my bikes and its great because I do not have to stop and swap out the batterys the system I use see the 2 batterys as one battery and I have a total of 48V 28ah with a range of about 140 miles using pedal assist 3 Throttle range is about 100 miles and can change depending on you weight and terrain

I had hoped to add axle extensions to my RK3 so it would fit into 190 mm drop outs on a fat trike. I think it can be done but unless you have a machine shop connection the trial & error becomes expensive. I'm now wondering if the RK5 might be an easier fit with it's 210 mm axle width? The chain stays cannot be bent since they are reinforced for strength. Thank you.

Any idea if the 3 speed model will fit on a super73 Z1? Apparently the rear dropout on the z1 is only 150mm, but I’m not completely sure. And isn’t this hub 170mm?

[THENEWWRANGLER]

can you post a link to the 5 speed one, I am planning to add one to my juiced bikes hyper scrambler and to my super 73 rose ave. thanks

[crashtestcal]

What kind of top speeds are you seeing on the 5 speed? Is 5th gear direct drive? How many of these 5 speed hubs have broken on you? Thanks for this video by the way.

[KingdomUploader]

So the old 'nuvinci' hub is obsolete now? thanks

[smarc]

bro. spoke lenght for the xs rk3 on 20 inch wheel please let me know

[ricklane]

I have a ludicrous mid drive with 26 x 4, want to use belt system, what do you think, or stick with chain?

[gabrielcc]

Can you tell me the differents between your model and this Sturmey Archer Rear Hub RX-RD5 5V 36 Hole? Thanks.

Does phatty cycles sell the hub gear only?
