Such a beautiful future where we can build awesome motorbikes with hella sketchy sheet. What a time.
-
This is one of the best E-Bike build I have seen on YouTube to date
-
This was such a clean build, literally everything was done to make it as perfect as possible..... Well Done man. I imagine this bike as having a very high resale value and you could ask a pretty penny for it and you would get it easily.... 😮🖤🖤
-
Beautiful Work Brother. I love it when someone takes the time to do these builds the right way. Thanks for sharing.
-
Hello from Germany. This bike was nicely designed. I’m not into dirt bikes, but this is sweet. I ride an ebike also built by myself.
-
I love custom builds like this with all this attention to detail but i never have the patience to do all this build work.
-
I just spec'd mine out with china.: 72v 8000w 40ah 100a controller, red frame, gold rims, headlights and brake lights, hydraulic brakes, 203mm 4 piston, zoom front and kke back suspension, motorcycle seat, alarm, color display, 19 inch turtle tires. 2100 delivered

Any halfway competent auto tech could replicate this and definitely should. What a killer simple circuit design and build, so sick 👌
-
I really like the the way you fused the input and the output thats tell me that you are knowledgeable man .and that difently the right way to protect the wires from getting overload current.and the input from getting over charged ..very professional...I cant imaging big companies selling their e bikes without even an input fuse 😂 they dont have money for that but its really against the safety rules & the NEC code ..dc current can fry any thing alive is not a joke to deal with Dc
-
Thank you for taking the time to explain the electrics in detail, will have to re-watch to take it all in :)
-
Felt like I was having fun without even being there 😄cool man very cool
-
Such a clean inside. I wish I was better with electronics to make things like this and run additional LED’s.. I’m learning but very slowly. update: Ended up getting the Garmata seat with the stash box and I think I will mount my controller there. Who knows. I plan to finish my build within a year or so haha. Already burnt one motor by the phase cables getting ripped from the disc brake :( I will attempt a 3D printed cable holster that holds a washer against the swing arm to prevent any drag on both sides.. that was one thing I didn't see was how you ran your cable through the disc brake.
-
Awesome set up! It'd be worth considering if batteries and motors weren't so ridiculously expensive.
-
Excellent explanation of wiring up a high power ebike. saved for my future build. thank you!
-
I almost wish I went to school for electronics instead of welding. You’re awesome man. Wish I could remember that much information.
-
FANTASTIC! I want to thank you for the electronics crash course in the beginning -- illustrating the function of the relay and how the positive and negative current factors in. I am a COMPLETE novice and do not understand electronics (actually fear it). But with that explanation, I am beginning to understand it a bit more, despite my previous failures. Do you teach electronics or something? Anyways, excellent job and presenting it so that an idiot (like me) can understand it. (smile)
-
i would 100% buy this exact model. i just love how it looks. even just the frame and ill put the electronics in myself.
-
Just re-watched this. Such a well done video! Thanks. So 8000w at 60mph, 2000w at 25mph.
-
That’s a nice motorcycle, definitely not an ebike at that speed. Would recommend putting turn signals on it too. Crazy how that feature isn’t more common on ebikes.
-
I know the bat straps should keep the bat from sliding forward and contacting the angled part of the frame, but I would put a bumper between the battery and the angled frame.
