    Is this used cargo ebike worth the price?

    2014 Xtracycle Edgerunner with a BBS02 kit, 1100 miles on it. Guy wants 1500. Worth it? How long does a li-ion battery pack last? I'm a bit concerned about the age. Thanks for any help.

    Swap SWXK Guts into Another Motor Housing?

    Hey guys, I found a bike that has a bafang SW series motor on it but has a 3 pin connector on it (I'm guessing no hall sensors), while my controller has 9 pins and requires halls. I have a SWXK with 9 pins on it - can I swap the rotor/wiring out of that motor and into the new bikes wheel?

    Battery Charge Wire Shorted to Cell? Burned Nickle Strip

    Well my battery stopped charging this morning, checked the charger and output voltage was fine so I opened up the battery and found this, see pics below. The black wire from the charging port has rubbed on one of the ribs in the case so much that the wire broke. It looks like the wire shorted to...

    How Often are Torque Arms / Axle Flats Used? Need SWXK Help

    If the axle nuts on a hub motor wheel are properly torqued, will the axle ever rotate enough to make physical contact with the flats in a dropout or torque arm? Don't get me wrong, I'm not anti-TA, just trying to figure out if they're more for insurance if they get used every ride. I have a...

    Can I Save these Windings?

    So I was trying to make some new hall sensor pockets in my old MAC motor and I got way too aggressive and damaged a winding or 2. Yes, I know I'm an idiot. Not only did I reduce the cross-section of the winding but I'm pretty sure they're now shorted to the stator. I can think of 2 options...

    This Motor Sound Normal? Varied power draw at full throttle

    https://goo.gl/photos/ZyYWJdQupRWT7ondA This is an older MAC front hub motor with a Kunteng sine-wave controller. In the video I slowly push the throttle to full and hold it for a bit, twice. It's not loud but the sound isn't uniform or consistent, it makes some funny noises at seemingly...

    Controller/Battery Stops Supplying Power to Motor?

    I finally finished my build and it's so much fun to ride, but I'm having one nagging issue and am unsure of the cause. It only seems to happen when I really hammer the throttle or set PAS to maximum assist from a low speed or going up a hill. The screen stays on, just the motor stops turning. I...

    Throttle/Controller Issue, S-LCD3, MAC 350w, C2 Parameter?

    Hey guys, I just installed my MAC 350w with BMS Battery 48v battery and integrated 18A sine wave controller (https://bmsbattery.com/ebike-battery/774-48v116ah-case-08-bottle-panasonic-battery-pack-battery.html), and I'm getting some strange behavior from the throttle. The motor power "cuts out"...

    SWXK Front Hub Motor Road Bike Build

    First, thanks to motomech, LewTwo, John (rumped6), and everyone else at ES who helped me find the right parts to achieve my goals with this, my first build. This is a great community. This build started out with a 2012 MAC motor from John but unfortunately it wasn't playing nicely with the...

    Limit Initial Torque with S-LCD3?

    Has anyone successfully done this? I'm trying to prolong the life of the clutch on a MAC motor by forcing it into a "soft start". I read the thread below but I'm not sure if any of the parameters will do what I want. My best guess is P4 and C5, but they offer speed limits not torque limits...

    LCD3 Waterproof/resistant?

    Also, does anyone have experience with this LCD in the rain? Wondering how it holds up to moisture. I want to start riding my bike more but it's a rainy spring here. https://bmsbattery.com/ebike-kit/670-s-lcd3-lcd-meter-for-s-series-controlers-ebike-kit.html

    Sunthing-28 Lithium Ion Reviews?

    Anyone have good luck with them? I read a lot of good things about LiFePO4 batteries from Sunthing-28 but I can't find anything about the Li-Ion. I'm specifically looking at the 48v 12Ah linked below. Follow up question, will this battery work OK with a MAC 350w front hub motor and 25A...

    E-Bike Kit for Seattle

    Hey guys, I was just introduced to ebikes by a coworker a couple weeks ago, and now I find myself constantly distracted by reading and researching them. I recently moved to Seattle and my typical commute is only 3 miles each way to a park and ride where I catch a vanpool. I typically drive my...
