I must admit. This is by far the best looking diy ebike “system” I’ve seen. Congratulations! Great work!
Why he doesent sell it ??
Sell them dude you will earn money
agree!
Please! Get more of those frames made and sell them for two three or even four times your cost! Depending on how much they cost you that is. minus the motor , controller , and battery just as a little diy kit I would easily pay 100-150$ just to avoid the fabrication. Heck, if you included all the components i would easily pay 350-450$ but I’m cheap. You could probably get away with charging whatever you want considering how legit you designed it! If you are able to charge double the cost of what it takes to produce then you could be selling them faster than you can produce them guaranteed. Great design though for real. I’m going to attempt to copy it for my bike that is just like yours. I want to know where you found the parts for the freewheel on the main sprocket! Any chance you can provide a parts list with links? Please please please!
Great work. Can you post a ‘How To’ video, explaining the build?
I don't think I'll make one because this motor is only compatible with my specific bike and only with my size of frame
@@DAZprojects Pretty sure it is adaptable to any bike that can receive a mid drive such as Bafang BBS motors...
@@v1ncen715 no because it mounts in a different way
@@DAZprojects Might be more similar to Cyc or Cyclone motor mounts, but my point remain - apart from the slightly different frame shape that would require different shapes for the aluminium plates and 3d printed bracket, it seems completely doable on many bikes.
@@DAZprojects I am sure it can be adapted to many frame with slightly different mounting plates.. it looks very similar to Gng / LightningRods / cyclone motor mounting systems.
Wow this is the most clean build of DIY so far I see... the placement of the motor is great too.......
Quite apart from the ingenius engineering for the motor, your riding skills on the downhill trails are to be admired - well done!
Impressive DIY work!
You got skills man! I work on electric motors and compatibility and fitment is a challenge. that custom mount and battery adaption was brilliant.
This is a really awesome idea! 👍👍 We are so happy to be one part of it. BTW, wish you have a festive season🎄🎄
Seriously what a build.. bravo
Great concept and locations!
Pretty clever dude !
Genius! Well done David, Nice video 👌🏼
Nice work - would be good to try one of these on my old Capra
Impressive stuff !
Well done on designing and building the ebike motor, looks great! After watching the video, I have a couple questions about the build. 1. What is the idler gear and spring attached to? The aluminum PCB part? 2. The motor sprocket welded/attached to the bike sprocket, was there already clearance on your bike for the second sprocket or did you have to make modifications? Thanks.
Nice compact build!
well done!, will probably build one this summer as a side project, unless you plan on selling custom ones for other bike!
Finally someone has figured out that you need double down gearing. Multiple sprockets gives a multiplication of the torque which is the most important parameter making an ebike motor solution. Well done!
I'm now working with an Italian bike brand to make a way better e-mtb motor, can't wait
Absolute genius!
Absolutely brilliant build. You clearly have a good eye, along with all that engineering gray matter. Looking forward to more of your builds. Next, I hope to see a torque-based sensor for pedal assist, and before you know it you'll have developed a system that rivals the best mid-drives on the market.
th-cam.com/video/b3uZh1AIQq0/w-d-xo.html this is my latest build, it's a massive improvement over this motor
awesome! its time to show that there is not just only comercial versions.of ebikes, users experience is the best! just a torque sensor/pas will be a nice upgrade
amazing, really really nice job👍
Somebody at CYC motor hire this man!
Decent build!!!
Impresionante trabajo, además puedes actualizar con baterías dewalt de 10ah, solo te falta hacer un pequeño carrenado con una impresora 3D para protegerlo de polvo y barro. Mis respetos por este gran esfuerzo.
Brilliant work 👏 i wish i would know someone like you to help me build an engin like this on my dh bike❤
Nice work! I really like how light and simple the motor assembly is. How is the motor holding up? What drew you to the 5065 motor instead of something like 6354?
I chose a 5065 motor for the lighter weight and the cheaper price, also i don't think i would need more power than what it can provide since it can output up to 1800w
bro, it is so cool! build one for me 🙏
Dude
That is AWESOME!!
Are you patenting or sharing how have you done?
I'm not patenting or sharing how i built it in details because it would be compatible just with my not so common bike and only with my size of frame
great job
Whats the price fir the pcb. Way parts ? Can i buy it ? From you ????
Great build! What about the cadence? Does the motor determine the cadence? Or does it adapt to your cadence?
It adapts, but I'm working on a pedal sensor and various upgrades
What part did you use for the freewheel gear? I'm having a hard time find a similar part for my diy ebike.
It's a standard MTB single Speed freewheel
Hi, just built the same setup, could You share more info what values You set in vesc ? Got the same gear ratio but the motor is weak, I have it set for 20A from battery. I've changed wattage from 300 to 1000W in Vest but with no effect. It is weak - i mean when the bike stays on ground motor can't even push the bike (without me on the seat).
Great build and nice video. The music not so good.
Great work congratulations and great video too!!!how many watt are in the battery?and how many Nq are in the motor ,please!!!tnx💡
Check out the pink bike article about this motor, it has all the info you are searching
Price fore the parts ??
Thanks !!!
Awesome
Awesome build! How much did the cnc components of the bike cost?
About 100$
did you try tsdz2 motor ? did you made double freewheel crankset ? and is it possible to add some torque sensing to this?
I actually own a tsdz2 motor but i don't like how it stocks out below the frame
No, the cranks spin with the motor
I also built a mid drive system ebike but using scrap parts.
But the motor is 5 times bigger and is 2000w 84v
Has freewheel on motor & the bottom bracket crank what is homemade
It has cooling mods cooling fans & more.
It's very powerful & fast
I use it like a motorbike and the motor heats up very fast.
That's my biggest problem with it.
So how does that small motor handle the heat.
I can imagine the size of the motor it will be useless on a bike.
With more voltage
I can't imagine after 20 minutes of constant used it be ready to melt🔥
There's a reason why people don't use these motors on ebikes.
But the motor is running with 20v hate may not be a problem.
At that low voltage
I'm surprised it barely moves without you pedalling.
If it had the power
You can't anyway because it has no
freewheel on the bottom bracket crank.
So you need to pedal at the same speed.
So legs don't get ripped off LOL.
Apart from that you've done amazing job.
Good quality
I wish I had the machine to do stuff like that.
At the minute I struggle with my hands.
Takes me days hand making simple stuff.
What can be done in minutes on a machine.
How much does it weigh?
Try a 60v battery
V2 coming in the next video, completely different design and components, works better in every way
Grande, bel video. Ma di dove sei? Sembrano posti vicini ai miei:)
Bergamo
How much does this cost to create in parts and fabrication?
About 100$
you are genius can you share this 3d model?
This bike was really easy to assemble th-cam.com/users/postUgkxMesz3KOGEmwmvyKQfLfrRSUXLFzfVHZA and required very few adjustments out of the box. The wheels did not require any truing/adjustments. The frame had some small scratches, but nothing major.I did replace the seat though - the seat it came with was very uncomfortable. The tires need to be re-inflated every 4-5 days, but this appears to be quite common for the narrow 700x25 tires.Overall, in my opinion, this bike looks and rides like a much more expensive bike.
What's the keyword for that tooth sproket?
Man I cannot find you on IG 😢 can you send me the link? I’m so interested about the details of the project.
I only have my private one
Hiii again, can you send me the cad files ? I just wanna try to build it for me bike 😃
dude, can you make and sell these???
Stai per mandare in rovina la bike industry mondiale 😂
Vedrai il prossimo video (incrociamo le dita che funzioni 😅)💪👊
Whats the total gear reduction?
It's approximately 1 to 12 at the cranks, the reduction at the wheel depends on the gear you're in
@@DAZprojects So assuming an average pedal RPM of 80, the motor is typically spinning around 1000 RPMs?
@@MrHamncheez yes, infact the gear reduction should ideally be lower, the perfect one should be 1:20 but i didn't have enough space to fit it. However after building it i came across a strange type of cycloidal drive which gives huge reduction in a tiny space while needing only 2 components so remaining super simple. Maybe in the future I'll make a video update changing to this type of reduction
@@DAZprojects I've played around in fusion 360 with a hypoid gear. Its possible to get 40:1 reduction in a single stage at high efficiency. Since they are also a type of bevel gear you can reorient the motor, allowing space for a longer, narrower motor
@@MrHamncheez what type of gear is it?
Please go commercial 🙏🙏🙏
I want one as well
Put it into production bro it will soon put all the over priced ebikes out of business
Sell it!
