I know a chain is the best way to go if this was the only thing to worry about. It now wheight 65kg and 110kg with driver and ready to go. I don't think that is much consider I have 4 motors and 5000watt. I would say that it's not perfect but good enough. I also need to be able to lift it up...

Ok I got it. But if we look at the rc world which I also is deep down into. You would choose a hi turn motor for a rock crawler and a lower turn for a racing buggy and they use the same battery voltage. I special ordered my Mac motors directly from the manufacturer with 16turn and a single side...

Ok very good info. I thought you only could do that with sensorless motors... I guess we are lost in translation sometimes ;) Sent fra min FRD-L09 via Tapatalk

As a car mechanic I see what you mean but I don't think it's the whole truth... You can also build a V8 to work on high rpm in a F1 car or build one for a tow truck that gives a lot power at low rpm. They could theoretically have​ the same volume but it's the internal design that make the...

It's rated at 48v and 1500w. I don't need to go fast or use mor power than that.

Hi guys. Leaf motor say the can make a 80rpm@48v motor. http://m.leafbike.com/mobile/products_detail.php?ProId=1077 I tried to contact them to get some info about efficiency and maybe a graf but they always refer to the website or a copy-paste answer. I don't know if this is a good motor for...

You are absolutely right. There is a 3-pos switch on handlebar that control power to front wheels. it's set to 25/60/100% [THUMBS UP SIGN] 60% is the perfect sweet spot. Smooth and little wheelspinn. We ride this thing almost every day and have now done 80km in rough terrain and had the first...

So I finally got the girl to try it a few weeks ago. This is the first time in 16 years she was able to go out in the woods like she used to do. She took it very carefully on this first run but loved it! It's still some work left to do but now I know it works good enough to finish it...

Thanks! I like it a lot, can't wait to play around with it and see what it can do. If I have to much heat problems I guess oil cooling is the easiest way to go. And because it's not fast I think it would work great and not centrifuge the oil out...

It's geared motors, you can read more in this thread Quad / https://r.tapatalk.com/shareLink?url=https%3A%2F%2Fendless-sphere%2Ecom%2Fforums%2Fviewtopic%2Ephp%3Ft%3D82322&share_tid=82322&share_fid=55725&share_type=t Skickat från min iPhone med Tapatalk

Yes, 4 controllers one throttle, I linked to a 2wd thread earlier that have a good wire diagram, I modified it a bit and I have 4 switches. 1st for Power on, 2nd for reverse and that one turns off the front motor at the same time because they would only freewheel. 3rd for 2wd/4wd and last for...

Glad you like it. It's custom built motors for this project with 16T. I use 2x 6s lipo batteries I series 44.4v (fully charged 50v) I took it out today but I think battery voltage was to low and maybe the cutoff was effective because I only got around 1200w at most and max amps was 38A @ low...

I love rock crawlers, and this is my build of a "crawler-ispired-trail-atv" with 4 hubmotors, i got it running this week and looks promising, will do a update in my thread as soon as i tested it. here is a little video of first test in the garage. remember this is the absolut first test with no...

Hi again. Since last post I managed to buy 2 used chassis without electronics. These chassis are a bit different from the one we borrowed. They been modified to work like a manually wheelchair, they're much narrower in the back and uses single shaft wheels. I will try the simple way first with...

Nice! very good info, I also would prefer a chain drive, and with a smaller wheel I probably could fit one of these motors https://www.ebay.com/itm/201532811502 in front of the wheel and get the weight further front. But there's a balance between simplicity and over engineering ;) I want it to...
