    What reliable, low-power motor for 3rd world touring?

    Ok, here's a new functional requirement to throw at this project: the battery system must be capable of charging under pedal power. As far as I can tell, a stokemonkey-style setup should still work fine, but with a small direct drive motor instead of geared. I'm thinking maybe the NSM, as it's...

    What reliable, low-power motor for 3rd world touring?

    Jonathan, thanks so much for all the information! Especially for holding my hand through usage of the motor calculator in a mid-drive setup. What's making the most sense to me at this point is using a small geared hub stokemonkey-style to the bb. I looked at that dd hub but it's about double...

    What reliable, low-power motor for 3rd world touring?

    Aw shoot, I totally forgot that the BBS01/2 is all internal gearing. For some reason in my mind I had been equating it with something like a GNG/LightningRods kit, where you could just remove the chain if the motor crapped out. I still think a mid-drive could be advantageous for the gearing...

    What reliable, low-power motor for 3rd world touring?

    I could envision an airless tire working better with a multi-durometer profile. Maybe a thin/hard center rib and a pair of outer ribs. Fill the remaining profile with much softer foam. The hard center would have a reduced rolling resistance, but if you hit a bump and experienced a dynamic...

    What reliable, low-power motor for 3rd world touring?

    I just spent some time exploring the greater depths of the interwebs looking for additional feedback on airless tires. Trying to get as many data points as possible, ya know? The consensus among people who have tried them out seems to be in line with most of the concerns that have been voiced...

    What reliable, low-power motor for 3rd world touring?

    Curious, why would you opt for a 8t/10t mac vs something like the Outrider? It's double the weight, which I'd like to minimize. I think the biggest factor in motor selection will ultimately be reliability. With something smaller like a Outrider I could probably bring a full extra set of...

    What reliable, low-power motor for 3rd world touring?

    Thank you kind sir for the great ideas! It very much reminds me of a friend's travel camera - he wrapped a nice point-and-shoot in the outer cardboard of a disposable digital camera, and used a crocheted sock as a case. You really had to look hard to notice that it wasn't an actual disposable. I...

    What reliable, low-power motor for 3rd world touring?

    I had already planned to leave a complete assortment of spares with a trusted friend/family member, for essentially the same reasons you listed. Nice to hear it from someone else though. I have the tools/skills to replace questionable connectors with some better, sealed ones. That's actually...

    What reliable, low-power motor for 3rd world touring?

    So many great thoughts and discussion in this thread - thank you all! I think friction drive is out, mostly for fear of effectiveness in wet/muddy conditions. A small hub motor has been the most appealing thought, due to the size/weight. I'd been thinking of a rwd setup but perhaps a fwd setup...

    What reliable, low-power motor for 3rd world touring?

    That's the gist. I'm looking to build up a 29er XC bike with fat-ish tires (2.5 - 3") that I can use for 3rd world bike touring. The fat-ish tires because there's a good chance of sandy and muddy conditions. The idea is to use a relatively small battery pack and carry deployable solar panels...

    Quick questions about pedelec direct drive motors

    There's a wider variety of frames than you see there, but that gives the general idea. Unbeknownst to her, she's actually going to get fitted at the shop to help with frame selection. Kiriakos, thanks for reminding me that the decisions are mine - but that doesn't mean I have to like it! It's...

    Quick questions about pedelec direct drive motors

    Fyi, the frame is going to be one of these: http://www.shopcalfee.com/1-booganda-bikes/ Long story, but this bike is actually being built up as part of a work trade, so hence the bamboo frame. Still leaning towards getting a BBS01 kit from Em3ev...

    Quick questions about pedelec direct drive motors

    Near 60, good hiking shape but currently suffering from an ankle tendon injury due to over-use. My parents' idea of an after-dinner hike is 10 miles up and down a mountain. She doesn't currently ride this commute because of the distance but has been considering an ebike to make it an easier...

    Quick questions about pedelec direct drive motors

    I'm actually starting to lean back towards a bbs01 for my mom's bike. Paired with an igh, it seems like a pretty slick system. No external controller, integrated pas, basically plug-and-play. I think I'm at 80%. Gotta decide asap...

    Quick questions about pedelec direct drive motors

    Could you elaborate on what you mean with respect to 3 speed targets? Do you mean that, if I set it at PAS Level 1, it will essentially deliver power like a step function, with 3 steps that correlate to different speeds? Just not clear on exactly what you're describing on a practical level. I...

    Quick questions about pedelec direct drive motors

    After giving this a bit of thought, and riding a few off-the-shelf ebikes locally, I think I have a plan. After riding a cadence-sensing bike I'm afraid that might be an intimidating power delivery compared to the torque-sensing, which was smoother as expected. I think a small geared rear hub...

    Quick questions about pedelec direct drive motors

    Thanks so much for all the replies. To answer the big question, no, I'm not overly attached to a dd hub motor. Some very ebike savvy friends have pointed me in that direction but I feel like I have a grasp on the other options (mid drive, geared, etc). More than anything I'm looking for an...

    Quick questions about pedelec direct drive motors

    Hey all. Longtime lurker, first post. Just to get that out of the way. Long story short, I'm building up an ebike for my mom, which she'll be using for commuting ~10 miles each way. I've got a buddy who's helped point me in the right direction (crazy/amazing guy - calls his ebike the...
