Production of the Grin All Axle Hub Motor, with Cargo Wheel Preview

A company owner, boss working on the production line? This is what I call dedication. Thumbs up for Justin?

[@ericwainwright7876]

Why would anyone expect less of a class act like Justin? I always lead from the front in my company, that's how you inspire loyalty and dedication to the company, that's what makes it a team effort.

[@mattmatolcsi6457]

Wow, expanding production and developing new designs, very impressive! Grin shows no signs of slowing down!

[@Mark-ev8qb]

You are amazing! You will be the first company I will go to to get the parts to build my electric Bike! I have watched all of your videos. WOW!

[@JamiePineappleWyatt]

Now that's much more like what I imagined when you guys designed the first all axle hub motors. Amazing work!

[@haatch999]

This sooo awesome to see this. This one video has explained about 100 questions about very nuisanced things and I’m an even bigger fan I am making a bunch of e bikes and this motors simplicity and ease of manufacturing is what I strive for

[@inklipMedia]

Looking forward -- I hope to see a cargo trailer wheel you could slap onto a motorcycle pull-behind trailer or small automotive cargo trailer. Or maybe I'll build them...

[@meppieomg]

People are gonna look back on Grin Tech like they do Bell Labs.

[@peritube666]

Congrats Justin and Team! you do a great job, from desining to the customer.

Nice hun motors. thank you

[@ChrisOlin]

holy crap, are you guys accepting interns? I wish I could quit my job and move to BC for six months just to work for you.

[@chrisprice5806]

can the phase runner work with those typical 500watt bafang hubs? i wanna upgrade my display and controller to something more set-able(like throttle responce, max speed, amps/power)

[@GrinTechnologies]

Yes it can run literally any bafang motor as long as you tune the settings correctly and wire up the hall sensor and phase wires.

[@chrisprice5806]

you are the man. not The Man but the MAN!

[@simonlinser8286]

badass man, living the dream

[@Jahmall841]

I was wondering if someone had the latest Grin all axle hub with L1019 on the disc side. Could the opposite side cover be replaced with a cassette cover to be used now as a rear hub motor 🤔? The design seem simple yet very efficient.

[@GrinTechnologies]

The axle is different in the rear motors. The cassette freehub will not fit over the diameter of the front axle, it needs to slide over a 15mm shaft.

[@physiqueDrummond]

the windings! where are done the windings! also (macroeconomics inquiring mind here) how much time? Labor? Parts? QC rigs? R&D? tell us all! we have a post collapse biking world to prepare!

[@GrinTechnologies]

The stators are supplied to us prewound from a stator factory. It's an impressive sight, rows of automated winding machines sad far as the eye can see.

[@GrinTechnologies]

We have done pics and video snippets from our last factory tour and could make a little video. Doing the copper winding itself in house here at grin doesn't make sense now, but if societal collapse is the horizon then who knows what'd be on the table!

[@H4N5O1O]

wish I could still do that type of work, diameter ? can you just bolt on a couple of wheel rims and seat a tyre direct to motor ?

[@GrinTechnologies]

Yup. It's a 20" wheel diameter sizing. For most situations lacing the standard hub into a 20" bicycle rim works great and is a lighter wheel. But for heavy cargo applications it's nice not have any worry about spokes breaking and that's where these injection molded composite wheels are quite handy.

[@williamjones8507]

Would these wheels be better for the lateral loads a trike would experience? How soon might we be able to order?

[@GrinTechnologies]

The hope is that they would be tougher and more resilient than spoked wheels for these kinds of cargo applications and that's exactly what's being tested right now. Future tests will involve the wheel being inclined by 15 degrees on the testing drum to simulate the lateral forced present when cornering. Properly built spokes wheels are incredibly strong too and are lighter weight, but if they ever go out of tension (like from a dented rim due to impact) then they can quickly succumb to spoke breakage.

[@Jerbrown]

@@GrinTechnologies Hey! Did anything come of this test? I just emailed to order a couple of these wheels. I'd like to know if the strength when cornering is greater than the spoked wheel option. Thanks!

[@TheDirtydingle]

Please consider a 36H (spoke) version as well! I'm looking to buy this in the next year or so.

[@GrinTechnologies]

Why 36H? Highly doubt we'd produce that, it's been developed as a 32H Hub

[@masters40]

Really no need for a 36H hub if you're using a decent rim. I have a Grin All Axle front hub on my tandem and it is working flawlessly. We have a combined rider/bike weight of close to 500 lbs.

[@yushanthachathuranga5168]

Nice product.wish you for more success

[@dylandesmond]

Can you please make a more powerful and efficient motor than the 273 40h for 168v use

[@MPaulHolmesMPH]

What voltage range is acceptable for the hall sensor PCB inside the motor? Is it +5v, or is 12v possible? And is it open collector or is it push pull output?

[@GrinTechnologies]

The standard hall sensors usually work up to 24V on the rail and have an open-collector output with the signal pull-up resistor on the motor controller PCB. That makes them compatible with a wide range of voltages.

[@EricPeelMusic]

That was a two-sided load test. How much is safe for this hub/wheel combo for single sided loading? And what about lateral loading? I can imagine taking my dream build off road, approaching a steep lean and snapping a wheel before it rolls over and gets totaled. Any assurance this won’t likely happen?

[@GrinTechnologies]

Visit cargobike-wheels.com/ and have a look Ultimately the strength for single sided loading depends on how you build your own axle on the vehicle. The motor is hollow and slides over a shaft that is part of your vehicle design, so the key structural component is on your end.

[@EricPeelMusic]

Ok, that does make sense and I understand. Thank you. Now say the load was back to double-sided with the strongest axle of all time but applied at an extreme, 45deg angle. Now, not only is the axle responsible any longer but the hub and its fitment to the CBW3 is being torqued laterally. It will never be 45 irl but it could get steep enough to be a cause for concern. This type of load also occurs on sharp, fast turns on flat, level terrain. Can the all-axle motor and CBW3 handle that type of load?

[@fun_ghoul]

@@EricPeelMusic Are you planning a cargo bike build, or to challenge Pike's Peak? If the former, when will a cargo bike be in the position you describe? Anything will break if you exert enough force. The question then is, did you select the right tool for the task at hand? Without explaining your purpose, you can't expect to get a satisfactory answer.

[@EricPeelMusic]

@@fun_ghoul I’ll be frequently off-roading with a heavy setup. It’s obvious you did not design the hub motor or wheel in question and you won’t be able to help me.

[@fun_ghoul]

@@EricPeelMusic It's obvious that you have more money than brains. It's down to your swingarm and the bearings, brainlet. The end.

[@trevoradam7709]

What no statorade?

[@GrinTechnologies]

Our current workflow is that this gets added prior to shipping through a small M3 threaded port on the side plate. It does look cooler when squirted directly on the magnets though but it can also get pretty messy too.

[@724horndawg]

Nice job 👍

[@ShardCollector]

That looks expensive! And awesome!

[@russellzauner]

I need a motor that has about 130mm-150mm bore. I can't seem to find any on the shelf with larger companies; is there something in your lineup that can assist?

[@GrinTechnologies]

No, that's way outside the league of anything that would be required for ebikes or LEV's. If you have access to a machine shop then in principle you could take the stator and rotor of one of these motors and then modify the side plates to use massive ID ball bearings and then machine your own axle for it.

[@e-powersport]
