    2019 Bafang Ultra Battery Voltage Compatability

    Hello All, I am in the market for a Bafang Ultra, and since Luna is out of stock, I was speaking with a Chinese vendor. They implied that the motor was only compatible with a 48v battery. I remember seeing there was something different in the 2019 model, but can't find the thread. Is it an...

    2wd midtail Winter commuter questions

    Hello, I am currently riding a Bullit bakfiet for commuting and work as a property manager but have determined that it isn't suitable to snow and ice conditions. For my Winter ride, I am looking at having a custom frame built, which will be based on the Salsa Blackborow, but set up to be...

    BBSHD Dimension Question

    I am considering putting a Bafang BBSHD on a cargo bike, but the installation is complicated by the fact that the area below the bottom bracket is effectively a straight tube. Can anyone tell me how thick the frame can be from the inner edge of the bottom bracket shell to the outside of the...

    Introduction and proposed project

    Scooterman, Sorry I missed this, I was away mountain biking in NC for a week. I use Paragon Machine for most of the things you mentioned, here's a link: https://www.paragonmachineworks.com/, another place to look is Nova Cycles: http://www.cycle-frames.com/bicycle-frame-tubing/home.php. Nova has...

    Are these appropriate batteries? Drive thoughts.

    Amberwolf, Thanks for all the info. One of the challenges of Endless Sphere is the shear volume of information available. It is a bit daunting, even for someone who has spent a lot of time on various technical forums. I hear what you are saying, and fall back to the old saw, "you kinda get...

    Are these appropriate batteries? Drive thoughts.

    Maybe scratch build from A123 cells like these? as I remember it from R/C stuff, LiFe batteries aren't prone to spontaneous combustion...

    Are these appropriate batteries? Drive thoughts.

    Dogman, Is your story archived on here someplace? I've used R/C lipos for years, and have yet to blow anything up, but having said that, I've seen the videos. I'd prefer not to need to remove the battery for charging, just plug it in when it is in the garage. Maybe try to find a comparable LiFe...

    Are these appropriate batteries? Drive thoughts.

    Hello all, I started a thread over here: https://endless-sphere.com/forums/viewtopic.php?p=1361223#p1361223, on a e-assist bakfiet cargo bike I am scratch building. I think I have settled on a Cyclone mid drive from Luna Cycles. There are clearance issues with the Bafang BBSxx motors as there is...

    Introduction and proposed project

    Over the weekend, I had time to further research drive systems and put pencil to paper to do a first iteration of the frame. I really haven't decided whether to go with a mid drive or 2wd, but that can wait as I gain further knowledge. I have had a few e-mails with Scott from Luna and that has...

    Introduction and proposed project

    Thanks for the two thorough responses. The handling of a Bakfiet is something that crossed my mind. We'd be descending a mile of gravel with a 120 degree switchback before we hit tarmac. The front wheel is probably pretty prone to understeer unloaded, so that could be a problem. I know a few...

    Introduction and proposed project

    The trike is a non-starter due to how narrow and poor the roads I'll be riding are. The hill itself is 1200' of climbing. I'll look at mapping the steepest section and work from there. I guessed my weight may be off, for the exact reason you pointed out, but really wasn't sure. I figured I'd...

    Introduction and proposed project

    Hello All, I hail from Vermont USA and am an avid cyclist, am interested in reducing my carbon footprint, woodworking, etc. We live out in the country, 5 miles away and 1300 feet above the village, so virtually every shopping endeavor requires fossil fuels. We generate our own electricity via PV...
