    GNG, 1000W 48V BB-drive, $400

    Aagh! :oops: This is MotoMel from BikeMotive. I didn't hear until someone mentioned it to me through email that the spiralocks are unwinding. For whatever reasons, our builds didn't happen to have that problem. IN ANY CASE, I am MORE THAN PLEASED to send out as replacements the Omega-style...

    Motor and gear compatability

    Ouch! But of course knees are one of the *very good* reasons to add electric assist to a bike. Thanks for the info on the thermo tracking. I'm tackling that in the next week. (Moto)Mel.

    Motor and gear compatability

    What kind of temp sensor is it, and how is it positioned? (I know this thread is a bit on the old side.)

    Am very interested in researching, purchasing and/or building an on-board BMS for 24/36/48 v RC-type battery packs. Best recommendations? Thanks.

    Dual freewheeling bottom bracket design

    In the meantime, we posted a very primitive video on a RHS drive we concocted and have been testing over the past several months: https://docs.google.com/folder/d/0BwuAyZBgbD_MMk1obU90TU8tdmM/edit I'd enjoy knowing what your thoughts are on it. Mel.

    Dual freewheeling bottom bracket design

    Hi all. You're giving me every incentive to find a way to get them out there. I'll rattle the chains to our manufacturing suppliers over the Thanksgiving holiday and see what new quotes we can get. If the response is positive, then I'm likely to put the venture up on KickStarter to finance the...

    Dual freewheeling bottom bracket design

    The problem is the "not too expensive" issue. We're working hard on finding engineering changes and manufacturing sources so that cost (and therefore price) are at a reasonable level. We have, in the meantime, figured out how to use our custom spiders to create a crankset with 4 chainrings...

    Sweet! My gaze kept being diverted to the wall calender, however. 8)

    http://BearingsDirect.com (USA) might be another source, depending on your location. And I've found some odd bearings through http://LocateBallBearings.com, though their service is a might sketchy.

    Re-fit Turnigys with on-board BMS?

    Thank you all. You have disabused me entirely of the notion of deploying such batteries! MM

    Re-fit Turnigys with on-board BMS?

    Tesla (and/or others) - Would you help me understand how, if the BMS is onboard already, a simple battery charger safely operates without communication with the BMS. Thanks. Mel.

    Re-fit Turnigys with on-board BMS?

    The AllCellTech units come complete with batteries embedded, and there would be no fooling with that. For the past six months or more, AllCellTech has been looking into a hard plastic shell for their batteries, but has not come to market with one as yet. The aluminum shell would add noticeably...

    Re-fit Turnigys with on-board BMS?

    Great information and suggestions, thank you. I have to date provided a retrofit kit w/o the batteries, but have been asked to look into supplying those as well. I will divert my attention to the solutions perfected by others and perhaps partner instead of being the direct provider. As always...

    Re-fit Turnigys with on-board BMS?

    :D You're spot on, Dogman!! Thank you for the absolutely justified concern about battery fire and safety. Actually, that's part of what is driving this research. :idea: What I am thinking about is encapsulating battery and BMS in rectangular or square aluminum tubing of various dimensions...

    Re-fit Turnigys with on-board BMS?

    I purchase lithium batteries for use in electric bicycles. Batteries specially created for this use are usually encased and have a pair of discharge wires and a 3-prong connector for recharge. These batteries are rated 36V or 24V and 10-14 AH. The respectively volted charger that plugs into...

    Is anyone in the forum offering motor rewind service?

    1. Where might I find, at this time, the best motor design/wind calculator for a non-hub motor? As far as I know, it does not need to be cluttered with various propellers, RC motors, controller models or weights. Does one of the older versions of the [drive calculator] program do a more...

    Is anyone in the forum offering motor rewind service?

    :?: Would there be any value in rewinding one of the Unites? It would be fascinating to try out one that was optimized for this application. Should the basis be a pristine unit, or can it be one whose windings have had their varnish burned off? I would probably want to install a temperature...

    Is anyone in the forum offering motor rewind service?

    Miles, thanks. I too have gotten enmeshed in those torque calculations lately. I would expect reduction rather than direct drive, but I would think it better to have it a one- or two-stage reduction rather than the 3-stage embodied in the Banebots 64:1 P80 gearbox. Are cycloidal and harmonic...

    Is anyone in the forum offering motor rewind service?

    Right, lfp. I have to admit that finding an appropriate motor and reduction gear for my setup has been very frustrating. There just doesn't seem to be a good commercial source for what seems to be a pretty main-market request. And that's looking across Cyclone, Banebots, and a whole host of...

    Is anyone in the forum offering motor rewind service?

    Have thought of rewinding one or more available RC motors to change voltage and KV and delta/wye, but at this moment would prefer to outsource it. Are there any suggestions about where to get that done? Thanks.
