Thanks AmberWolf for sharing :) I found that helpful to know and others in the future may do also.

@andrebandre I don't know if it varies depending upon the type of dropouts (horizontal or vertical), but do you know if something like a torque bar or similar is needed or recomended with the SA 3 speed Hub with 8-9 speed cassette please? Thanks for sharing you knowledge :)

It is that vs potentially; chain-line issues, wearing through chains quickly, wearing through cassette sprockets quickly, and possibly derailing the chain often. Its a choice, life is not perfect.

Maybe you need to add a gear senor to stop the motor when changing gears, or tap the breaks (assuming you have brake sensors) before changing gears. The 3 gears of Sturmey Archer are reconned to be more sturdy than many hubs as they are less complicated, try to pack less gears into the hub and...

http://www.sturmey-archer.com/en/products/detail/cs-rk3-black Gear Ratio • Overall Range - 177% • Gear 1 - 75% (Gear 2 - 25%) • Gear 2 - 100% (Direct Drive) • Gear 3 - 133% (Gear 2 + 33%) PLUS it you can put a shimano compatible sprocket cassette on it. They say 8 to 9 speeds but I think...

Thanks very much Donn and John61ct for the clarification on the above point :)

Its true there are more teeth to spread the load on so manufacturers often figure its OK. But there are folks who do try and go full power up steep hills on powerful ebikes at high torque and I have heard of at least a few large sprockets on the back buckling. So I mentioned it as there are many...

No worries you are welcome, just one of the many options I have come across and looked into in the course of studying up on ebikes :) The Box 2's biggest sprocket is not steel and so best not to put too much power through it just in case. I was unable to find a review of Box 2 ebike version, but...

Also some of the really old 3 speed Sturmey Archers are going from the 70s and even older ones with care and maintenance. There are videos of old SAs getting restored and still running. I am not too sure what MTBF and WAG stand for John61ct, care to clarify please?

Cheers Matmaxged. I think there is a lot o be said for the CVT of Nuvinci keeping the cadence steady and the sports and cargo Envilios being able to take higher torque etc, however there are some downsides too. The completely sealed form of the hub gave me some concerns that they couldn't be...

Not too sure what power, torque and gear range the SHIMANO STEPS E-BIKE Dedicated Mechanical Internal Geared Hub Disc Brake 5-speed can take. Anyone found any more info on it please?

I prefer the Box 2, 9 speed cassette for Ebikes, it is cheaper and packs one less gear into the same space allowing a thicker chain. 11-50 teeth sprockets.

The hub I was talking about originally has a direct drive middle gear, 1st is lower for hills and 3rd faster. Combined with a cassette with with say 8 or 9 speeds (I believe it can fit 10) gives more range similar to a Rohloff but less granny gears and faster top gear. Of course there are cons...

Oh interesting I will definitely have to check out the gearing and how much torque it can take. It doesn't seem so expensive, well compared with some IGHs :) Thanks MatMaxGeds

Thanks for the tip on the BMX chains Qwerkus, will definitely keep it in mind if I go with an ordinary IGH. Comparing Rohloffs with Alfines then Rolhoffs have way more climbing gears, like the sort of thing for a 20% or more gradient especially if not motor assisted (but lack the speed of an...
