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

    Sturmey Archer IGH with cassette and mid drives

    @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.

    Sturmey Archer IGH with cassette and mid drives

    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 :)

    Sturmey Archer IGH with cassette and mid drives

    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...

    Sturmey Archer IGH with cassette and mid drives

    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...

    Sturmey Archer IGH with cassette and mid drives

    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?

    Sturmey Archer IGH with cassette and mid drives

    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...

    Sturmey Archer IGH with cassette and mid drives

    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?

    Sturmey Archer IGH with cassette and mid drives

    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.

    Sturmey Archer IGH with cassette and mid drives

    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...

    Sturmey Archer IGH with cassette and mid drives

    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

    Sturmey Archer IGH with cassette and mid drives

    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...

    Sturmey Archer IGH with cassette and mid drives

    Thanks for the feedback Qwerkus. The downside gearing wise on the Alfines is that they lack gearing for extreme gradients, at least if it was relying solely on human power. But still going up a 8% with 135kg load is impressive. I am not too sure what the number of teeth on an Alfine is...

    Thanks AndreBandre looks like a wonderfully unique bike you have. I bet it is fun. Thanks for clarifying the short-hand and giving more pics and info on usage. :)

    Sturmey Archer IGH with cassette and mid drives

    Yep gear sensors that cut off power on the motor can help with that. Prior to their development folks stopped pedalling to change gears :)

    Sturmey Archer IGH with cassette and mid drives

    Thanks AndreBandre for sharing your experience. 20" wheels, is that a fat bike, a recumbent or a moulton style bike per chance? I am wondering what sort of terrain you are covering, road or off road, mostly flat or some hills please? Also I am interested to know what motor you are using? 5000W...

    Sturmey Archer IGH with cassette and mid drives

    Thanks very much Markz for your reply, I have read the top thread before and found it interesting, not seen the other thread. Like most things, IGHs have their pros and cons, its a question of weighing them up with respect to our own situation. I am still mulling it over :) Good to have other...

    Heya, I stumbled across the Sturmey Archer 3 speed Hub with 8-9 speed cassette with disc brake mounting code: CS-RK3 Black product webpage http://www.sturmey-archer.com/en/products/detail/cs-rk3-black I am thinking of running one on with a Bafang BBS02, for touring on roads with pedal assist...

    Paralell Batteries on a Solar Ebike

    Cheers Bill Von for the helpful comments. Much material online I have read is old and bike technology moves on. But it is good to learn from the mistakes of the past, when still relevant. So I have stayed clear of parralell battery set ups so far, you have made me think again, and I think that...

    Paralell Batteries on a Solar Ebike

    Thanks for sharing your knowledge of how batteries in parralell work Wturber. I will definitely think it over. I am told that usually battery BMSs do not like to be charged in parralell. I guess from the other end of the solar charge controller, without separation, it seems that the other...
