- Опубликовано: 7 июл 2021
- This video goes over the wheelbarrow from Bafang that we've been offering at Grin Tech. Our recent 2021 shipment of these motors has been updated to include a combined speed/temperature signal in the Z910 plug and can be used for lots of neat low speed but high torque drive applications.
We've had this hub up on our motor simulator for a while now:
endless-sphere.com/forums/vie...
But interest in this hub keeps gaining more and more traction and we'll be making it a staple part of our hub motor and kit offerings.

He ha .....finally found an off the shelf rig for my cargo trike trailer , 9 kmh is fast enough for me ,
that's about the max speed of my self built delta cargo trike , now I'll be able to go off road camping . The trailer is about 8 feet long with portable head and serves as a tent plaform . With a couple of these wheels I could make the trailer bear proof which will ad weight giving the wheels more grip ......thanks for all your efforts and time
You know what a lot of people in alaska do to keep bears out of their cabins is a bunch of sheetrock screws threw a piece of plywood and leave them under every window and in front of every door ! The black drywall screws are super sharp! I would space them about 2” apart ! Maybe to save weight and for camping something similar that rolls out? Like some kind of plastic or carbon fiber!?
great video, and great explanations all around.
I remember 15 years ago when folks ran metal gears in the BMC and MAC hub motors, really noisy, so your gears lasted but the clutch got destroyed, good to see they removed the clutch in this because that wouldn't have lasted for the same reason, really nice idea, may be a market for ready made barrows, if you don't "Luna" Barrows will 😜 great stuff.
Quite a surprisingly large number of "ready made" electric wheelbarrows have already sprung up on the market just in the last 2 years and I expect this will continue to gain traction. The Makita is one of our favorites (other than the slow top speed), but for similar reasons to ebikes we think that there will always be a retrofit / DIY market even when there are lots of turnkey's available.
That’s awesome and ill be getting one ! But the one thing i have always wanted besides a wheelbarrow with a motor is a small machine with a small scooper bucket to move dirt, rocks whatever! One that moves with hydraulics that could be used to actually load the wheelbarrow!
Good presentation of an interesting concept.
Seeing a cycle analyst on a wheelbarrow is just too funny 😂
Hmmmm how much weight can you put on that wheel? I’m thinking about what I can use to build a game cart to carry deer out. Is there a way to wire 2 wheels onto one control so they could be used kinda like a moving dolly/hand truck kind of a rig?
Never mind, $700 CND? Heck no.
Could it go real slow with a fine adjustment...maybe a hi / low range planetary setup..?
Can you show more about the control by end-user pushing (pulling) the barrow? I imagine one mode could work like a 'hover' board, with the tilt controlling drive, but obviously there are many situations where tilt has more to do with navigating hills and bumps, so manual throttle would be needed?
Never mind, you have a more hands-on (fun!) vid here (ruclips.net/video/WFv62Y8isO4/видео.html). Please see my comment there re: my project Twitter @eMULE for a bicycle-style but super high-capacity powered cargo trailer. Maybe you can help me find/develop or find a contact at Bafang or elsewhere, to mount a wheel motor on standard independent-suspension trailer spindle/axle assemblies.
Send one to "seth's bike hacks” he needs one for his backyard trail and it would be a good for his 10 product review videos.
Nice! I want one!!
Can this work with out a fork style axle mount? As in can it be used as a wheel that’s mounted on just one side. I want to build a small electric quad for my daughter and am wanting to use something like this for the rear wheels. She is still young and not the best driver so I want it to go slow but I want it to have enough torque to get over most obstacles or climb hillside as her skill level increases. I don’t want the rear axle to be a solid straight shaft locking the wheels together and I don’t want to mess with a differential so I figured two hub motors for the wheels would be ideal but most of what I can find will be too fast and have no low end torque.
Hi Nathan, it's certainly not designed for single side mounting. For fairly light loads you could get away with this just clamping the one axle on the cable side, but not for anything that needs to carry any substantial weight.
So if it's just a small quad for your daughter and her weight is split across two motors on either side it will likely hold up fine.
Nice one! Wonder if this has application as a jockey wheel? I know you can already get powered jockey wheels but this might be better/cheaper/superior in some other attribute.
Never heard of a jockey wheel till now with a quick search but yes that is exactly the kind of low speed and high torque area where it shines. The differences to this over the commercial powered jockey wheels is that this wheelbarrow hub is probably a lot faster and has a larger diameter for rolling over bumps, but it probably doesn't have as much pulling thrust. So if those are the attributes you want it would be a good bet.
Does this mean it is also now possible to get the normal bike version of the g311 motor without a clutch (and so with regen)?
No, the bike version needs to have the clutch since it has thrust bearings to deal with the axial thrust of the helical gears on the rotor and planet gears. If locked the clutch and put torque on in the other direction, then the axial thrust would be in the other diection and the rotor and planets would bottom out.
Hi. What is the slowest this wheel can go and how much weight can be distributed on 2 drive wheels and 2 lazy wheels?
You can run the motor as slow as your motor controller allows, some controllers do have a motor stall timeout if the erpm falls too low. Each motor axle can easily support several hundred pounds.
What a great idea guys. Wonder if the concrete guys will buy a few? Great asset for hard to get to places and have to wheel in concrete
I talked to my ex-boss about getting a concrete pump, he was totally against it. he prefers wheelbarrows pushed by laborers lol.
@@chrishayes5755 lol
How Much ? to power Erie Barrow setup ?
I find the problem with electric wheelbarrows is stopping them with a load. Is this or are there regen capabilities that could regulate downhill operation? Disk brakes?
Yes, we cover regen in the wheelbarrow kits in some detail here ruclips.net/video/WFv62Y8isO4/видео.html
Good idea
can this be adapted to use on a trike? possibly as an assistive device?
Sure, if you could modify the trike to use a custom fork with ~155mm dropout spacing and 12mm dropout slots then it would be work fine, assuming that you really don't need more than ~9kph speeds.
i have parkinsons but have been riding a trike for 10 years to keep moving. i currently have one trike operative w/motor. i can see the potential for a low speed adequately powered "add on" so i guess an easily adapted possibly portable setup would be difficult to develop?
Could you please tell me the size of the shaft. 12mm?
It's an M16 threaded axle with 12mm flats
Love this and just what I need, where can I buy this?
The links are in the video description.
Use this on a small boat(Rib inflatable) trailer from a distance of less than a mile to the water. So, no need for a vehicle to tow...
feasible?
For sure, but most boat trailers are 2 wheels, so there would be a steering moment on the trailer unless you had a 3rd wheel upfront (like a trike) or ran dual motors as the two trailer wheels
Hey there I am using two of these for exactly this purpose. I built raiseable launching wheels with one motor each to carry the rear and a separate raiseable two wheel setup for the front. The whole setup can be left on the boat while on the water
@@shanek1506 Nice! Do you have a link of the specs, pics of your boat?
has anyone used a scooter motor and wheel to do this?
How can orders?
Grin is Good
I cannot find this item on your website. A phone number to customer service could also help. I would like to know more about this wheelbarrow motor. I could use two of them !
Hey Stuart, the wheelbarrow kits are on the website dropdown under Shop > All Kits > Wheelbarrow (last one down at the bottom) ebikes.ca/shop/electric-bicycle-kits/wheelbarrow/basic-electric-wheelbarrow-conversion-kit.html
Thank you for the link Aaron. I'm looking it over now. I hadn't had access to this nor has any of the four e-bike companies that I contacted by phone. I don't see all of the attachments shown in the video but I'll will continue my search. Thanks again
Send one to Colin Furze. He needs one coz he is digging a tunnel from his garage to his house
No mention of battery?
The typical kit would use a pair of our LiGo batteries.
How can I get this product

couldnt you design the motor core to be an outrunner so the magnets would not fly off if it is powered by 72 volts.
outrunners have the magnets on the rotor like most ebike hubs like the direct drive and the bafang used by rad.
inrunner is like what the bbshd and cyclone uses where the magnets and rotor is inside the part with the windings.
it would be nice if you could design a wheel that would work on appliance dollies
Yes, but this isn't our motor design, it's Bafangs. They took a great inrunning motor core (same as the G310/G311) and greatly increased the gear reduction to the hub. Even if the magnets were better bonded and didn't come off at 72V unloaded speeds, the hysteresis and eddie losses of the iron core would cause the motor to overheat at those RPMs even if there was no load on the motor at all.
You had me till you said tube and entire, aren't we done with inner tubes?
They said 20s later that it can be run tubeless if you want to.
@@kschleic9053 I'd personally opt for solid rubber tires if possible. For this application you aren't as concerned about cushion as you are reliability. It likely won't be traveling long distances and will be required to carry heavy loads through rugged terrain. For example if you used it for a home construction project, it could have a high chance of encountering loose nails.
Give me a.tube over.that.messy gunk anyday. For a building site tubes are fine
@@captaincaveman8532 a puncture a day on site
great so overvolting a Wheelbarrow is out >:)
I mean, technically running them at 36V is overvolting by a factor of two as they were engineered for use at 18V and 4.5kph moving speed. You can in principle disassemble the motor and reglue the rotor magnets with a higher temperature rated adhesive, and then it is possible to operate at even higher rpms. We used to do this frequently with the ebike motors.
@@GrinTechnologies Are you saying that you could run this off a single 18V tool battery without modification and the only difference would be cutting the moving speed in half?
This company will grow huge, and fast. This is the future.
Make the phaserunner bluetooth an have small display
I know uumotor also has similar motors with high torque
I like it, but full wheel barrow goes for $700 now.
interesting
I would like to put these wheels on a retractable pool cover.
You could, and they would do the job just great.
This would make sense if the batteries anf other required component didnt bring the price past the cost of a pre made machine
It will run fine of cheap lead acid batteries like are include with almost all the pre-made electric transport carts. You can also run it off power tool batteries just fine which most people already have around.
I'll give this half a day for the tradies to destroy. It'll be wet and half cemented.
Currently we're going over 18 months among some tradesman moving concrete, dirt, rocks, you name it, with not a failure yet!
@@GrinTechnologies Impressive
I bought one of the after market hub motor kits from aliexpress. I stripped a gear, with no known way to fix. It has however convinced me to go with this again on a more known brand. It has saved me thousands of dollars in hill landscaping.
It's too bad this product does not exist. Everybody that deals with the Bafang hasn't a clue of any wheel barrow hub motors. It's also impossible to contact or speak to the people that made this RUclips video. I was told by several e-bike company that this may be a prototype. They know nothing about any wheelbarrow motors any place. Too bad there's no customer service for Bafang motors. You know, somebody you that you can speak with by telephone ?
Hi Stuart this is not a prototype, we've been supplying these motors for over two years now and currently have them in stock here:
ebikes.ca/shop/electric-bicycle-parts/motors/geared-wheelbarrow-motor-with-tire.html
Bafang is not a consumer facing company, they are a B to B entity and are not known for ever answering end users. So any questions generally need to be directed to a competent dealer selling the part and not to Bafang directly.
this makes no sense to me. USD$524.00 USD$1,304.25
USD$1,428.00
There are many options you can choose (controller, battery(s), charger etc.) when buying a full kit. If you just want the simple price of the motor, it's right here:
