    Looking for help sourcing a motor for my ebike setup

    Feerchobby and flipsky have exceptionally bad reputations (they also sell several of the same rebranded motors). How much cheaper does the unwound motor cost compared to pre-wound motor? Have you had issues with QC or with motors being finicky? Maybe throwing a magnet or bad tolerances?

    Looking for help sourcing a motor for my ebike setup

    Woah, that bike frame looks sweet! I agree with your opinion opinion of using two motors but I was thinking that I would have to compromise if I wanted to get the power I need without a really thick motor. Where did you source the motor parts? That looks like the housing for the flipsky/...

    Looking for help sourcing a motor for my ebike setup

    Hey, quick update. I'm pivoting to a left side drive that connects to my rear brake rotor mounts, I was worried about losing my rear brake so I will be wanting to use regenerative braking through VESC. I am looking for a motor that can handle around 80-120 phase amp bursts and put out enough...

    plans to build a mid drive in ns snabb

    I was looking at the QS90 70H and the thing that makes me not want to use it, is the width. Either I'll have to completely forgo using my normal bike drive train or I'll need to position the motor so that the shaft runs along the length of the bike, and then use a 90 degree gearbox to turn the...

    Looking for help sourcing a motor for my ebike setup

    I totally agree, I was browsing for a motor last night and realised that since I am still using a few gears on my casette, I shouldn't have to worry about using as much power as I was asking for. I think looking for 2kw will be plenty since I like the headroom to keep temperatures low. I also...

    Looking for help sourcing a motor for my ebike setup

    Sorry, I misspoke. The X60 has an absolute encoder, not a continuous encoder. As far as I can tell, continuous encoders do not exist or at least is not a term that is widely used.

    Looking for help sourcing a motor for my ebike setup

    Right, that is clear to me. I just mean that I do not understand how brushless motors work and while it may be within my ability to learn how they do work, I worry that even that knowledge will not let me fix the problems that may come up with that setup. It feels a little too far from what I'm...

    Looking for help sourcing a motor for my ebike setup

    That process sounds intimidating and it would probably be challenging enough for me to worry about doing. I think I'd rather not do it just so that problems that my bike ends up having are things I can fix on my own. Learning how those motors work and learning to troubleshoot their problems...

    Looking for help sourcing a motor for my ebike setup

    Do you know of any issues which would arise if I just use high chain speed on a middle gear (my 22 tooth gear for example)? That way I could use the gears with good teeth engagement, would have a small load on the motors and chain, and I would still be able to have the rolling speed that I want...

    Looking for help sourcing a motor for my ebike setup

    That's very intriguing, I think that'd be a fun experiment but that is definitely beyond what I'll be doing with my project. Thanks for explaining that concept. I hadn't considered the noise of the motor, maybe I'll go look that up and see if any of the motors im looking at are overly loud. I...

    Looking for help sourcing a motor for my ebike setup

    Sorry, I wasn't being very clear. I am speaking specifically about my mentality when I'm building it and riding it. I don't want to be a Surron guy because I feel like those people lack discipline and I don't want to fall into that hole. If I'm being completely honest, I want a dual sport that...

    Looking for help sourcing a motor for my ebike setup

    Bevel gears need to have shafts that are held at both ends and two of the ends need to be almost intersecting. To support those close shafts, I'd need to machine something that is beyond my CNC mill's ability since it would need to bore holes from the top and the side. I could 3d print something...

    Looking for help sourcing a motor for my ebike setup

    I'm well aware that all motors like spinning fast and with as little load as possible (see the thread above). I was planning on gearing it down around 100:1 which should be doable with a two or three stage (stage one being the combo gearbox) gearbox. Using two motors would mean that each one...

    Looking for help sourcing a motor for my ebike setup

    I've found the Turnigy-Aerodrive-SK3-6364 and the Flipsky equivalent. They both put out about a good amount of torque and rpm. I was thinking I could buy two and use a gearbox to join two of their output shafts. I could then use a single stage gearbox and have plenty of turque or flexability in...

    Looking for help sourcing a motor for my ebike setup

    Just to be clear, your comments have merit. I'd prefer to not use a worm drive gearbox but that's the idea that I think would be within my ability to manufacture. I don't think I would be able to manufacture bevel gearbox that'll hold up. That's why I'm looking for alternative motors and...

    Looking for help sourcing a motor for my ebike setup

    That GreenTechAuto marketplace is exactly what I've been looking for. They have a much better selection than the other ones I've been looking at. Thanks for the suggestion. Something else is that I guess I don't mean "cheap cells". I'm not looking for anything really nice but cells that won't...

    Looking for help sourcing a motor for my ebike setup

    My plan is to use a >9:1 gear ratio so that I can extract as much torque as I can from this system and run the whole thing on very low amperage. I believe that a nylon double worm with a stainless steel worm gear will be efficient enough not to melt and create the reduction I am looking for. I...

    Looking for help sourcing a motor for my ebike setup

    Well I get the issue with some really cheap ones, I also understand that lithium batteries are very dangerous if mistreated. I'm looking for something that I can build for less than $200 which feels fair given that the cells from the SPIM08HP battery pack would only cost $120 and are quite safe...

    Looking for help sourcing a motor for my ebike setup

    I'm looking to make my first ebike. I've gotten my hands on a 2019 Commencal Meta, I'd like to make it a commuter in a really hilly area, I also want to take it on some trails so ground clearance maters to me. I want it to be a mid drive because being able to shift gears lets any motor I use in...

    BAFANG BBSHD 1000W Vs hub 3000w - questions.

    Realistically you won't bust a chain badly enough to need a whole new chain, you can just repair it completely legitimately with a masterlink
