    Clicking Noise BBSHD Help me diagnose.

    Hey could use some help from the BBSHD gurus's out there. This just started happening. Anyone have a clue as to what's going on? It sounds like it's coming from the motor or BB. It's not the chain that's rubbing on anything or my chain guide. It's not any cables that's rubbing up against the...

    SW102 Display EggRider Clone for Bafang Display

    Hey guys, Just curious if anyone has used or tried the SW102 Display from Aliexpress it looks identical to the EggRider v2. I've been through three eggriders and tired of the expensive replacement. Wondering if these work for 1/2 the cost? Questions: What about Firmware? Do I have to flash...

    All Mountain trail Bike build and advice.

    I went right from a 26" Cross Country Specialized Epic with a BBSHD to a 27.5" All Mountain bike at first, with out a BBSHD and the first thing I noticed, is that I was not struggling at all over the sections I struggled with the 26" that 1.5" diffrence in wheel size made a considerable...

    All Mountain trail Bike build and advice.

    I've ridden all over North Georgia and although I don't ride the free ride sections I do ride all the black trails and I can say the BBSHD kit has held up rather well not a single issue. I've put over 300 miles over the last four months I've gone through a set of brake pads, and my dropper post...

    Wet Conditions BBSHD Strategies?

    I typically put a rag over my egg beater when I go to wash the bike down. I also use low pressure. I did notice on the throttle they use some sort of conformal coating on the small pcb board and some electrical liquid tape stuff around where the wire goes in. I wasn't expecting to see that.

    Wet Conditions BBSHD Strategies?

    Who out there is nervous about riding their BBSHD bikes in the Rain? For the commuters what have you done to make your e-bikes "water resistant"? What is everyone doing to protect your electronics? I do the following and just curious if anyone else does this and or what else are you doing? I...

    Off Road Battery Size recommendation for BBSHD

    For me what helps is if you adjust the thumb lever closer to the ground that way my thumb has to engage at a lower point. It's just a simple work around and doesnt address the real issues.

    Off Road Battery Size recommendation for BBSHD

    Bottom line I'm going to just enjoy it and replace it when it craps out. I'm just going to continue to do what I do. 90% charge and every 5 or so charges do 100%. When it craps out I just get a new one. No point in sweating out the minutia you will never be happy. People had me worried about...

    Off Road Battery Size recommendation for BBSHD

    I think I would rather get another 8ah or even a 6ah pack. Just swap them out when I deplete one in a safe range. I have a 17ah and for me it's way to big and heavy. I would rather give up some range for a smaller pack and swap them out. But that's just me and it would cost quite a bit more to...

    Off Road Battery Size recommendation for BBSHD

    I only ride trails mostly intermediate and advanced trails blues and blacks I get about 20miles of hard lots of ups and downs. All in the North Georgia mountains. I've also been charging the pack to 90% not 100% I've heard this is supposed to prolong the life of the pack and every 5th charge or...

    GNG / CYC X1 Pro 3000w

    I've had a couple of BBSHD with offset chainrings. Also I have a 1000 miles off off-road riding over a year and a half on two bikes with slightly off chainlines with out ever have broken anything. Not even a chain. Chain pops are easily addressed with a chain guide for less that $20. I had...

    GNG / CYC X1 Pro 3000w

    Hey guys, I currently have a BBSHD on my mountain bike. Is there anyone that can compare the BBSHD to the X1 Pro? Has anyone done a comparison of the pro's cons of each system? Also how does this system do off road. I only ride off road just on the weekends on Single Track All Mountain Trail...

    Using fire retardant foam to isolate the pack would also take a lot of the risk out.

    Off Road Battery Size recommendation for BBSHD

    I guess my biggest reservation about wearing a pack on oneself is the minute possibility of the pack catching fire while it's strapped to you. I'm sure you guys have seen what a lipo fire on YouTube and it's friggen scary. With all of the constant changing environment variables when riding...

    Off Road Battery Size recommendation for BBSHD

    I'll try to explain the whole makeup of a battery in my non engineering not to technical layman's terms. So my pack is 14s2p meaning two collums of 14 batteries wired in Series connected by 2 rows in Parallel for a total of 28 batteries. You take 14 cells and wire from the negative terminal...

    Off Road Battery Size recommendation for BBSHD

    Im still trying to figure out this BMS thing. So the vendor states LVC kicks in at 41v. However the BMS also kicked in if the voltage of an individual cell reaches a certain voltage. Independent of the total voltage. Is this correct? Is that an "if or". From my perspective and not sure if this...

    Off Road Battery Size recommendation for BBSHD

    So here is the response I got back from the vendor, Related to the ebay 52v 8ah 21700 T40 Samsung battery. "Me asking the question: Hello, Can you tell me what type of BMS is on this battery and what is the Low Voltage Cutoff (LVC) set to? Vendor: bicycle_motor_works It’s not any specific...

    Off Road Battery Size recommendation for BBSHD

    Unfortunately the egg rider doesn't tell me what the individual cell voltage is. So basically what your saying is there is no way to tell based on pack voltage when LVC is going to kick in? Then why do people assume it kicks in at a certain voltage. Like 44v or don't let it go below 42v.

    Off Road Battery Size recommendation for BBSHD

    What does that mean in English? That LVC kicks in at 3v +-.1v? Wouldn't that be the individual cell count? All Greek to me. So can you tell what the voltage cut off ? I'd like to verify. My pack is 2s14p so 28 cells 4.2v at full charge. Help me out with the math here. Is detection delay 100ms...
