    I had read a thread over at endless-sphere.com and a poster made a good observation.

    These internal gear hubs have more friction inside and don't roll as effortlessly as a hub without gears inside.

    But there was a thread over there that give the 5 speed praise.

    Amazon has Nuvinci 360's for $197... I came right up out of the water on that one. Just like a hungry bass. I'm planning to use a shift sensor as I like it and have grown accustomed to it on my derailleur setup.

    I really like my Sturmey-Archer 3 spd. On the SA site they say their 5 spd is made for heavy duty use. They don't say that about any other hub So is the 5 spd stronger than the 3 spd? If I build another bike I am going to try that 5 spd. They are very affordable.

    Actuallly the 3 speeds are stronger than the 8 speeds with the igh...even stronger than the nuvinci.

    I would recommend the nexus 3 speed.

    I don't have a shift sensor. On all my builds, I have a brake sensor on my rear disk that I keep a bit loose so I can use brake lever as sort of a clutch. I do slow my pedaling down when I shift. You can feel and hear when motor is not on. Alfine is made to shift best when not under load with or without motor. It is a great solution, especially if you have horizontal dropouts.

    Do you have a shift sensor, or just easy on the pedals when you shift?

    I have an Alfine 8 IGH on a Surly fatbike with a Lexi Blingring and BBSHD and have a perfect chainline. Bike can briskly climb grades that I wouldn't want to walk up. These have a very robust gear 5 but I have had no problems in any gear because I don't shift under load. This IGH didn't like being shifted under load without a motor.

    I really have limited knowledge on a bunch of this electric bike stuff yet, but I was looking for something else besides using the gearsensor I ordered with the kit. I was a bit hesitant to start cutting cables without knowing for sure the gearsensor was what I really wanted. Didn't find anything I liked, and was getting tired of letting up on the pedals to shift, so I just did the gearsensor. Very glad I did, it really works well.

    8 th gear eh?? I'll remember that... and try and hang out there more. 11 th seems to be my sweet spot for paved rode travel, 18 mph, easy pedaling, and about 3.5 AH draw.

    You will need a gearsensor to shift under power with the Alfine 8.

    Can the Alfine 8 be shifted under power? Or should a gear sensor be used to reduce pressure during shifting?

    That makes sense, I appreciate that kind of trivia. I wish Rohloff would make a robust 5-speed, or 8-speed. Just had an idea...3-speeds are inherently more robust, they could make a 3 X 2 = 6-speed? (We can dream?)

    Just for the record, inside the Rohloff is a close-ratio 2-speed, alongside a wide-ratio 2-speed, and 8th gear has the most efficiency, with least friction. All German case-hardened steel, much stronger than human legs could possibly stress it. Intended to be a lifetime purchase, then passed on to the kids...
    It might even make you feel like a kid too ;-)  I want one...
