    Large-ish (34t) nexus/alfine sprocket hack?

    That's a great point, thanks. Note that this hub comes stock with either 24t or 30t, which makes sense b/c it's lowest gear is 1:1 so it needs a big sprocket to be practical. I know, 30t vs 34t isn't a huge jump, but if it was even as easy as ordering a sprocket and dremmeling some tabs it'd be...

    Large-ish (34t) nexus/alfine sprocket hack?

    > get a smaller chainring It's my impression the rear cog is /usually/ the easier option. This bike has a nice-looking shiny chainring+guard, it's not immediately obvious if the chainring can be changed independent of the guard. But if it's easy and only affects how it looks, that's a nice...

    Large-ish (34t) nexus/alfine sprocket hack?

    My mom (~70yo) wants to get an ebike with a Shimano Nexus 5E IGH (this Electra Townie), but the lowest gear is 33.92 gear inches. The mid drive motor is 50nm, 250w, so pretty mild, which is great honestly to give her some extra range. There's a couple hills around her town that I think she still...

    Help pulling the trigger!

    Awesome, thanks for the feedback. The kiddo didn't sleep much, so it's one of those stare-off-into-space days for me. I'll have to use tomorrow's brainpower for this. Good point about direct drive and drag. Falco claims no drag, is that BS?

    Help pulling the trigger!

    I had a long reply to everyone on my iPad, but it seems to have been eaten... I'll try again, although I don't have as much time right now. Thanks for everyone's critiques - It's all just ideas until I spend the money to put it together. Then I'm stuck with it. One critique of the plan pretty...

    Help pulling the trigger!

    I’ve been researching ebikes for a long time, and have been unable to pull the trigger on a new build so far. I did get a basic 250w front hub kit for my current bike, but that was always a stopgap. I would love a sanity check on my current direction, maybe it’d give be the confidence to drop...

    Sanity check: I'm thinking mid-drive, but all I see are hubs

    OK, so what I'm hearing is that for my particular wants, say going up a 10% hill with 250lbs, one solution is to beef up my hub motor so that I can keep it at an optimum RPM, is that right? I don't actually care *that* much about how fast I go up, mostly that I can choose to expend less effort...

    Sanity check: I'm thinking mid-drive, but all I see are hubs

    I'm moving to a very hilly part of Seattle with 7-20% grades (Vashon Island, to be precise), I weigh 185, and I add an extra 30-40lbs weekly for grocery runs. I currently have a bafang 250w/24v hub motor on a throttle, and the little guy struggles with my weight and quite some oomph from me at...

    Undervolting, motor selection, etc

    > For the short term, I would recommend dual torque arms(easy without a disc)and a $25 Walmart AA powered H.lite as a back-up. Agree, maybe I'll never get past this stage. And I'll start shopping around for a new fork too. Maybe you saved someone's face today! > Why not take the $300 to $400...

    Undervolting, motor selection, etc

    OK, don't know how I didn't find this earlier, but check this out: http://ecmweb.com/content/how-save-your-motors-during-brownout So I should definitely match my motor voltage to my supply!

    Meant to attach this, since it's kinda interesting.

    Undervolting, motor selection, etc

    Clearly the evidence bears out that conclusion, but The Hill Topper website and staff (I picked up the motor in person) is sort of a zombo.com for electric bike kits, claiming it all just works. From the Hill Topper FAQ: Q: Do I need to use a torque arm with the CR hub motor? A: No, a 250 Watt...

    Undervolting, motor selection, etc

    First of all, thanks to all you endless-sphere-ers, this is an incredibly useful forum! I think I've learned enough to ask the right questions. TL;DR, ~180lb rider sometimes hauling up to ~40lbs up Seattle hills, currently totally happy with a Bafang SWXK 24v 250w given how stealth it is (I...
