Re: Sturmey-Archer 5-speed hub, it's real!

I'm tired of replacing the gears on the chinese planetary gearbox motor and the cassettes/internally geared hubs. I'll be looking into a more reliable solution from now on.

Re: Sturmey-Archer 5-speed hub, it's real!

Yes, so I might try my hand at a 3 speed hub when this one blows up.... Otherwise it's back to a casette, and replacing chains and gears every so often. I guess what we really need is an internal transmission that goes with the motor setup. I think 4 gears is all you really need at this power level ...

Re: Sturmey-Archer 5-speed hub, it's real!

My sturmey 5-speed doesn't seem to be taking the power very well. This was expected somewhat.

4th gear sounds like it's going to go and 3rd might not be far behind.

Re: Sturmey-Archer 5-speed hub, it's real!

I was planning to install a 40a BBSHD on my 9-speed derailleur style FS fatbike but it seems that only the triangle packs from Luna support more than 30a continuous draw and that bike has a pair of Sharks with 30a BMS's. That means I'll soon be running 40a through my SA 5-speed at 52v..... I'm runn...

Re: Sturmey-Archer 5-speed hub, it's real!

It's exciting but still un-proven. I'd like to discuss the changes that have been made with the newest 5-speed compared to the previous model. I can't find much on the previous model though. even 3 speed beats the hell out of 1 gear for torque starved ICE motors especially on motorized bikes, mostl...

Re: Sturmey-Archer 5-speed hub, it's real!

I just purchased an Sturmey IGH RX-RK5 for my bike, however I'm having trouble with the chain slipping on the front kog. What kind of kog do you use on the front? I know the RX-RK5 uses thicker chain, because we could not use 9-Speed bike chain on it. However, the new chain we're using keeps slippi...

Re: Sturmey-Archer 5-speed hub, it's real!

I ended up just going without a tensioner or derailleur. It's a 1600 watt cyclone kit basically, and 44t chainwheel up front.

Re: Sturmey-Archer 5-speed hub, it's real!

Also, I've looking at the diagram of the Rx-Rk5, and I'm not really sure how the gears are selected, or where the load paths are going. It would be nice to compare to the previous model. http://www.sturmey-archer.com/files/cat ... RX-RK5.pdf

Re: 1/8" chain slipping on 3/32 chainring

Another question though. How are you supposed to shift these Internally Geared Hubs? I never shift under motor load, but I heard somewhere that they only actually shift gears when the hub is off-loaded. Before I had an internally geared hub, I had a standard 9 speed cassette, and I'd shift it but le...

Re: 1/8" chain slipping on 3/32 chainring

I solved the problem by not using a derailleur or tensioner. It's pretty tight, I just hope it doesn't break something.

Regardless of kog size, 1/8" chain should work for all these components.

Nice .... I note that the specifications sheet list 3/32 cogs. Might one of those resolve your problems ?

Re: 1/8" chain slipping on 3/32 chainring

Harold, I've been following this discussion and even though you don't think the slippage is at the back I have to believe that that is where the problem originates, and then maybe causes a skip on the front chain ring. My best guess is that something is wrong at the derailleur tensioner. An easy ch...

Re: 1/8" chain slipping on 3/32 chainring

That shouldn’t be happening. Here are some things to check: Was everything fine before you have installer the hub? Could the chainring or chain be worn? Did you shorten the chain? Are you sure that the slippage is at the chainring and not at the rear cog or inside the hub? Avner. Everything was fin...

Check for tight/ seized/ stiff links in the chain and maybe lube it a little.
Also look for wear on the sprocket teeth.
the sprocket and chain are brand new

I've tightened the chain tension with the old derailleur but the chain still slips when I put moderate pressure on the peddles.

Re: Hey There

So it's getting to be about that time where i will be needing new gears. Is there a place I can order from directly besides aft or the chinese supplier? The chinese company is kind of difficult to get a hold of and AFT is kinda far away and expensive.
