    TSDZ2 Newbie with lots of basic questions -

    I so thought this was going to be referencing British slang.

    Motor decision for long john cargo bike w/ steep hills

    Oohh... very nice. That box build is great looking. Do you have a thread detailing that? I've seen that frame used by a few different "brands" but never seen one used by a real person. How is it treating you?

    Same one as you. I messaged you back when I was starting this whole process after I came across your build thread. You can see I've made a lot of progress...

    Motor decision for long john cargo bike w/ steep hills

    I missed your post originally. Thanks for the input. Mind me asking... if I plan on rarely using the full output from the BBS02, would you still recommend the HD instead? I have read about the design being an improvement in several ways, but then have read conflicting opinions (such as qwerkus...

    Motor decision for long john cargo bike w/ steep hills

    I really do appreciate all the feedback and I know all the extra advice is intended to be helpful as there are a lot of people who do crazy/stupid things with bikes. But my experience does extend into motorized applications as well. I work for a bicycle manufacturer who produces electric cargo...

    Motor decision for long john cargo bike w/ steep hills

    What I mean is that I know what my chainline requirements are, and what the resulting chainlines are from the various motor chainrings, so I'm not worried about it. Also, I'm very aware of my IGH torque limitations and gear ratio needs. I'm not experienced with the motors I've been asking about...

    Motor decision for long john cargo bike w/ steep hills

    Thanks for the replies everyone. I'm not sure how much closer I am to a decision though since I got a microcosm of the opinions I've been reading for the past couple of years. At least I think this has convinced me to rule out the TSDZ2 for sure. Leaning towards the Bafangs, although still not...

    Motor decision for long john cargo bike w/ steep hills

    I have my drivetrain sorted already and not overly worried about chainline since I have long chainstays and will be running an IGH. Although I'll still be trying to get it as straight as possible as long as the gear combos work out. Wish the Bafang dealers would provide chainline figures instead...

    Motor decision for long john cargo bike w/ steep hills

    Thanks again for the details. Your solution does sound very attractive, but I'm still hesitant since there are times when we don't have the ability to approach some grades with speed and it sounds like being able to gear down with a mid-drive might be needed.

    Motor decision for long john cargo bike w/ steep hills

    What is the steepest grade you climb with your bike? I've noticed on the simulators that the grade to overheating relationship isn't linear. There is a much longer 15% grade that I frequently climb, and several hubs can handle it without too much bother. Similarly, my Bosch bike cruises easily...

    Motor decision for long john cargo bike w/ steep hills

    No, just PAS. The person I replied to asked if I wanted PAS. Of course I would prefer torque sensing if possible, but outside of the TSDZ2, I don't know of any options that meet the rest of my criteria.

    Motor decision for long john cargo bike w/ steep hills

    Well this is part of why I've waffled so much because some folks say this, but most folks say that it feels very different (artificial) and that only torque systems like TSDZ2 feel like a natural bike. Does the BBS02 not have as good of a reputation? I know that they get thrashed by folks who...

    Motor decision for long john cargo bike w/ steep hills

    Thanks for all the feedback Amberwolf. I should have mentioned that ideally I'd also like the simplest and cleanest looking install possible, so definitely not interested in doing fabrication or big amounts of DIY beyond the basic install. I had ruled out Stokemonkey early on in the process...

    Motor decision for long john cargo bike w/ steep hills

    Not sure what you mean about being precise, unless this was meant as a joke and I missed it. The 200m is meters, 25% is the grade, 400lbs is the absolute max gross vehicle weight I imagine having. I have no issues with putting pedaling effort into the bike and would hugely prefer PAS. If I...

    Motor decision for long john cargo bike w/ steep hills

    TL;DR - 400lbs gross vehicle weight, 25% hill, long john bike. TSDZ2, BBSHD, BBS02, or hub motor? For the last couple of years I've been planning on adding a motor system to my long john, but I've got complete analysis paralysis and could use some help from folks who have first hand experience...
