    Adaptto Mini-E/Max-E Owner's Thread

    I asked a while back but don't think I ever got a clear answer, so here I go again: I'm building a 2WD Mini-E setup with a pair of MAC hub motors. I understand I'll need an external speed sensor (since they're freewheeling geared hubs). Several questions on this topic: 1. I assume I'll only...

    Electric Girvin Basman

    I have one of those Noleen linkage forks on an old tandem of mine, and kept glancing back and forth between that and my Luna. Wasn't sure what would be involved in widening it. Now I know. Keep it up!

    reachfar gps tracker and alarm rf-v12+

    I'm looking at the same alarm, and wondering the same thing. Seems like it could be a much better, more direct fit then using one intended for internal combustion. Did you get it, or find any more information?

    LumanPDX builds a Luna Cycles Fat Cargo Bike

    Well, looks like my post from last night disappeared, so I'll post again. I'm going to be deep in a work project for the next week or two, so this might be the last update for a while. But I'm really happy with where the bike is at now. The Luna still wasn't feeling right. Still a bit cramped...

    LumanPDX builds a Luna Cycles Fat Cargo Bike

    ok, I swear I posted an update last night with photos, but today that post is nowhere to be found. Does that happen here on ES?

    LumanPDX builds a Luna Cycles Fat Cargo Bike

    Yeah, really no worries. Building a small-batch DIY bike kit, I expected to have some rough edges to work out. If the fork had been truly unworkable, I would have shot you an email first to find a solution. As it was, it just took a whole lot of frustrated filing and pounding. I'm not surprised...

    LumanPDX builds a Luna Cycles Fat Cargo Bike

    Got a bunch of work done last night, and she's now technically rideable! Lets see here: The chainline looks like it's going to work out. But when that derailleur said it has a 28t max for the largest cog, they aren't kidding. I tried pushing it with an 11-30 freewheel, and it just won't lift...

    LumanPDX builds a Luna Cycles Fat Cargo Bike

    Thanks for the link. I'll probably go ahead and grab that alloy steerer. I ended up throwing a nicely machined Thomson stem on the bike (from my parts bin) and it's precise machining wanted nothing to do with the nasty flared steerer tube. I spent a lot of time hand filing that thing until it...

    LumanPDX builds a Luna Cycles Fat Cargo Bike

    I haven't tried to torque the bars yet, but they felt like they clamped pretty tight. I'm suspecting I'll need to toss the factory bars in a parts bin and throw something else on there, as at 6'1" that cockpit is feeling awfully cramped to me. I think I'm going to need at least another 2-3" from...

    LumanPDX builds a Luna Cycles Fat Cargo Bike

    Well, with the wheels finally on the Luna, it was time for her to make the way from the living room to the workshop. This project has officially progressed from the collecting-parts stage, to the making-it-happen stage :D I decided tonight I was going to get the fork and headset taken care of...

    LumanPDX builds a Luna Cycles Fat Cargo Bike

    Well, I got both wheels built up. I didn't drill the rim holes on the first wheel, and as a result I have a fair bit of kink in some of the spokes at the nipple/spoke junction. Not ideal, and a little disconcerting. On the second wheel I just marked the spoke angle on the holes, then stuck a...

    LumanPDX builds a Luna Cycles Fat Cargo Bike

    You can see in my follow up. I live in a fairly flat part of town, but there's hills all around. The Bafang mid-drives were very seriously considered, but I wanted to put about twice as much power to the wheels as they'd provide. If I didn't want to haul heavy trailers on occasion, it would have...

    LumanPDX builds a Luna Cycles Fat Cargo Bike

    Frame: The Luna Cycles Fat Cargo Bike I fell in love with this bike the first time I saw it here on ES. It got my imagination racing. The combination of cargo capacity and that built-in battery box sets it apart from most everything else. And those racks? HOLY CRAP. So pretty. So so pretty. I...

    LumanPDX builds a Luna Cycles Fat Cargo Bike

    Hey! Been lurking around here for years, but last fall the itch really caught and I decided it was finally time to build up my own electric bike. I figure my friends and facebook feed can only put up with so many messy build details, so I'd put all the graphic stuff here. So excited! Where to...

    Nissan Leaf Cells Test Data

    Would love to strap some of these on an electric motorcycle build. But these Leaf cells are far too big to fit in the Luna's battery box. Could stick a bunch in some panniers and ride across states though :mrgreen:

    Adaptto automatic onboard charger and coil connection

    Actually it would seem the most-most elegant solution might be a diode that prevents current from feeding from the controller out to the coil/charger? Does anyone know enough about the Adaptto charging system to know for certain how the connected coil affects the circuit and how to effectively...

    Adaptto Mini-E/Max-E Owner's Thread

    Speaking of the kill switch, I'm already setting up with a pair of 60amp breakers right off the battery. Should an actual battery-disconnecting killswitch be needed, or can we trust that simply cutting the controller's power is good enough? Since I need to use a speed sensor, I won't be able to...

    Adaptto Mini-E/Max-E Owner's Thread

    I'm trying to implement a 3-position key switch on my Adaptto-equipped bike. Essentially I want an off-accessory-ignition sort of setup. Closing the adaptto main switch is easy, but i'd need to pull some low voltage power to trigger the accessory relay. And ideally if the BMS goes into...

    Adaptto automatic onboard charger and coil connection

    I just realized the most elegant solution would be a 120v AC activated relay that could directly close the 48v DC circuit. That takes care of the whole connection/disconnection process in one package and is probably more reliable than using a microcontroller in the middle. But I'm only finding...

    Adaptto automatic onboard charger and coil connection

    I'm trying to plan out my onboard charging and trying to make sure I understand what's required here. I'll be using an Adaptto controller for battery charging, along with a pair of Mean Well HLG-240h chargers (24v, 10a). The chargers and charging coil will be mounted on the bike. My goal is to...

    Adaptto Mini-E/Max-E Owner's Thread

    So I've read up everything I can, but just wanted to confirm my charging solution... I'd like to use 2x Mean Well HLG-240-24A chargers in series to feed my Adaptto (with the coil of course). I can tune these down to about 44v in series, which should be just below the bottom end of my 16s pack...

    Magura MT5e

    Been hunting for the perfect pair of brakes for my electric cargo fat bike build, and the Magura MT5e (with the e-brake switch built in) look just about perfect. However I can't seem to find any information on when they'll be available for sale. Anyone have details on this?

    Spokes for fat bike wheel lacing job.

    I believe a single-butted spoke only changes size once. A double-butted spoke changes size twice. Generally a single-butt will be thicker at the head then at the threaded end. I'm sourcing some Sapim 13/14 butted spokes for my build.

    Lipos: Better to gently cradle or tightly constrain?

    I hadn't considered that, but I like the idea. Seems easy enough to implement. Have you noticed if it's effective? Does the tape get tight?
