    bbs02 steep hill best practices?

    Oh yeah, I did change out my rear cog on my Nexus 8 to a 22T to assist with the climbing. I did have to also get a new chain for the additional length. I can't wait until the weather gets better so that I can commute to work on this bike. My car lease (Nissan Leaf of course) is up in March...

    bbs02 steep hill best practices?

    fwiw, i live in the Pacific Northwest so it has been raining a lot. i haven't been able to take my bike out for the last few months due to weather, coming home late at night, icy streets, etc. but today all of the stars aligned...i didn't have to go to work, the sun was out, and the...

    DJI Phantom 3 Lipo Battery Issue

    I realize that I'm talking about a quadcopter/drone and not a bike but I figured some of you might be interested anyway. I have recently started flying drones and one of the interesting aspects of the phantom 3 that I fly is that it has a 4s 4480 mah lipo battery. It has a proprietary BMS to...

    bbs02 creaking under load?

    quick update. after racking my brain trying to figure this out and trying everything, i took my bike to my local bike shop today. I explained what I did to the guy basically saying "I recently put in a new bottom bracket, big chain ring, and chain on my bike and now I hear a clicking sound...

    controller hookup - ignition wire

    I also unplug whenever I'm not using the bike. I also built a precharge resistor many years ago and it's still going strong. Coincidentally, I just picked up 50 resistors today to make some more precharge resistors. I don't need 50 but it was only a few bucks and cost the same as buying only...

    bbs02 creaking under load?

    I spent some more time on this today. A few things that I tried: 1) I took off the cranks and tightened the lockring and the lockring cover. The lockrings were pretty loose. The lockring tool that I used when I installed this at work wasn't so good so it kept slipping. Turns out that I have...

    bbs02 creaking under load?

    I recently set up my bbs02. when i ride the bike, i hear a creaking noise when the bike is under load. i believe it is coming from either the chain or bottom bracket. the sound goes away when i am pedaling (or using the throtte) with no load (going fast on a flat, going downhill, etc.). when...

    bbs02 steep hill best practices?

    thanks for the info. does your bbs02 ever feel hot to the touch? i know it's not the best way to check heat but i don't have a thermometer installed. with my other bikes, i can sort of tell how hard the bike worked by putting my hand on the controller (if it's too hot to keep my hand there, i...

    bbs02 steep hill best practices?

    I'm pretty new to the bbs02 (just installed it this past week and have less than 3 miles on it). Does the throttle give more power than the assist setting? i.e., if I'm in assist 1 going up a big hill and it feels like the motor isn't helping, I can use the throttle and get some more help in...

    bbs02 steep hill best practices?

    ok, i may try that. i will say that at assist 1, it was almost as if i was just pedaling on my own so you're probably right. would it be safer to try assist level 4 or 5 instead of 9? i only go up that hill around 4-5 mph and i'm fine with that as long as i don't have to work so darn hard to...

    bbs02 steep hill best practices?

    what are the general best practices rules for riding on steep hills? i am using pedal assist so i am always pedaling. e.g., should i ride in lowest gear and use the lowest assist setting (setting 1 of 9)? obviously riding in highest gear with the highest assist setting is bad since the motor...

    bbs02 bike selection

    Hi, I'm planning to do a bbs02 install. I have 2 bikes that are potential bikes for this build. Please let me know if I am looking at this incorrectly in any way. 1) Breezer Uptown 8 - This is a decent commuter bike with slightly wide tires (26x2.25 is my estimate). It has fenders, pull...

    troubleshooting intermittent sensored gear hub motor

    The 12 fet will run sensorless so after I pull everything out and re-connect everything and secure the connections with tape (not solder quite yet), if it still has problems I'll try using the sensorless controller. The bike is dirty with lots of road dust and such because I usually ride along...

    troubleshooting intermittent sensored gear hub motor

    I'll try a new controller as this one is pretty old (about 4-5 years old or so and it is a lyen 9 fet controller). the motor is a 350 watt geared hub motor from ebikekit from back in 2011 or so. i believe that it's a mxus but not sure. i have an extra 12 fet sensorless controller that i can...

    troubleshooting intermittent sensored gear hub motor

    I have a bike with a 350 watt geared hub. I am running 12s lipo (44v) on it. I do take it up a steep hill sometimes which causes some heating but pedal hard and go up in a zigzag pattern to try to alleviate some of the overheating. This is towards the end of my ride so after about 0.5 miles...

    CycleAnalyst causes motor pulsing / power cutting in and out

    After some awesome help from Justin (yeah, that Justin), I don't know exactly what's wrong but I disabled the last wire (blue in my case) and plugged in the CA and it seems like it works now. Of course the disabled wire controls the throttle so CA features such as LVC, amp limiter, etc. will...

    CycleAnalyst causes motor pulsing / power cutting in and out

    It could just be a coincidence but I haven't ridden this bike in over 2 years. I was riding the bike for the first somewhat long ride (more than just around the block), went about 4 miles, went on a few bumps, and lost power. The motor was cutting in and out. I stopped and examined all of the...

    CycleAnalyst causes motor pulsing / power cutting in and out

    I've been racking my brain on this all morning looking at settings, etc. I am running the bike at 18s2p lipo (59v 10ah). This morning everything worked fine for about a mile or so and then it started happening again. I eventually disconnected the CA from the controller and rode back home. I...

    Melted a ebikekit mini-hub motor-2500watts cont.

    I'm using Lyen's 9 fet 72v controller. I used it before with a 26" wheel with a 9C motor (I think...the motor was a gearless direct drive from ebikekit). http://endless-sphere.com/forums/viewtopic.php?f=31&t=16998 The phase connectors are on 45 amp andersons so not great but hopefully good...

    CycleAnalyst causes motor pulsing / power cutting in and out

    LVC is set to 40v. Max speed is 99 mph. Max Amps is 53 amps. The only one of these that I changed was the LVC from 44v->40v a few days ago. I have never messed with gain settings so they should be at the default levels but I'll take a closer look when I get home today. I did change the...

    Melted a ebikekit mini-hub motor-2500watts cont.

    I have one of these motors on my cromoly folding bike. It works well in the sense that the bike is still relatively light and I can pedal for miles without ever using the motor if I don't want to. It is laced to a 20" wheel. However, I am running this on 10s2p lipo (37v 10ah) with a Lyen 9...

    CycleAnalyst causes motor pulsing / power cutting in and out

    i ran the bike today at 14s lipo just in case there's a phantom setting somewhere that's limiting current but no go. i tried plugging in the connector in/out a few times to hopefully clean it out but that didn't work. i suppose i can try the age old trick of blowing into it to remove any...

    CycleAnalyst causes motor pulsing / power cutting in and out

    thanks! you helped saved my commute back home today. i had to leave work early and everything was fine right up until i got to my hill on the last part of my way home. this started happening again. i disconnected the CA and it seemed fine. i went through settings and my CA lvc was set to...

    CycleAnalyst causes motor pulsing / power cutting in and out

    lol, i don't think i did but it's been 3 years so almost anything is possible. and i don't know if it explains why things seemed to work again after not working for about a mile. i have a hill going home later today and i surely hope there aren't any problems then. i'll really be in limp mode...
