    Yes. Here it is on Amazon. But you need to buy the disc...and the shifter, both are not included for this price

    For those that ride in assist most of the time this is true, but for technical off-road or if you spend a decent amount of your ride time without assist then the gears become necessary especially in mountain terrain. I may be in the minority for riding style but I try to use the assist only when necessary. For the record I tried a 3speed & it didn't work out for me but for the vast majority , as FolsomRider states, it would be perfect.

    I had a bad chain line that I was unable to resolve on a BBSHD with Luna 42T ring (consistently missed front sprocket hook-up in any gear above 3rd). Several recommended switching to Lekkie Bling but at $90. & a backlog, I opted not to throw good money after bad and switched over to a Shram G8. Over 200 mixed riding miles, I don't regret the decision but with a couple caveats.

    These are only my personal thoughts/experiences, every build and experience is different. I find the Shram G8 without assist to be even smoother and more user friendly than a high mid-range quality derailleur set up. Once assist is engaged I find the IGH much more finicky whether shifting up or down (yes, I know how to shift under stress) but I don't run a shift sensor. On the flats or downhill it's not an issue but on long climbs and/or technical off road it creates issues. I also question the durability of this particular IGH under load.

    Conclusion; 1. shift sensor may be a big benefit for an IGH. 2. For tarmac or single track, as long as you aren't constantly having to switch gears I highly recommend. 3. I'm not convinced of durability under excessive load. 4. Derailleurs are relatively cheap but need constant attention and under heavy use need to be replaced somewhat often. IGH's are expensive but as long as they aren't abused (like assisted by a BBHSD or worse a Cyclone and/or shifting under load), they need little in maintenance, should pay for themselves in outlasting derailleurs, and will cure most chain line issues.

    My son was riding my eBike, Motobecane 29+ with BBSHD, and somehow the chain derailed off the top of the cassette. Got stuck between the cassette and hub, locked up, and completely tore up the derailleur (SRAM X5). I do not know if the derailleur is even repairable. It's pretty bent up.

    I'd like to know what options are out there for a complete transmission upgrade. I don't know a lot about bikes, but I seem to remember a couple options for completely removing the cassette/derailleur and putting on a hub with internal gearing.

    Can anyone point me in the right direction for this?

    I am looking into IGH (Integrated Gear Hub) and CVT (Continuously Variable Transmission) hubs also as a viable option with the BBSHD.

    What got me interested in this is a build by poster ZeroGravity found here:
    http://electricbike.com/forum/forum/...-commuter-bike

    ZeroGravity's build using the N360 CVT hub seems good if your willing to back off on the power while shifting. As you cannot shift the CVT under power. And I'm not sure he has an obstacle in his path like I have (more on this below)

    In ZeroGravity's thread he mentions a guy named Karl (electricbike-blog.com) . Go there for sure and read up on his builds and experience with these types of shifting hubs. He covers the CVT's and Nexus pretty good and rides them hard.

    The obstacle I want to conquer...The hill that leads up to my house....An 800 ft rise in 1.18 miles (I'm assuming 13% grade or more at times over a 1.18 mile distance) .

    So I'm trying to figure out how to do this best with a BBSHD and one of these hubs.

    But my suggestion is to do some reading up over at Karl's blog

    I emailed Luna about this and they suggested a Rohloff as being the strongest and having the best range. But price wise I'm not sure this is the way to go. But Luna suggested this hub in a recent email to me.

    Currently, I am riding a Shimano Nexus 8 IGH with a BBSHD. I have had 150 trouble free miles, so far. I like it. Being able to shift into any gear at a stop is nice.

    I have no personal experience with IGHs but lust after one for my Dolomite build. I find terrific info right here on the Knowledge Base and Articles Tabs of the forum.
