The best hour and 40 minutes spen on eBikest. I learned more in this piece than in scores of hours of reading. What a guy.
Great interview and fantastic to listen to a hugely knowledgeable expert talking in depth on the factors involved ... as this was over 4 years ago now ... surely it's time for another update with Justin and cover how things have changed over the past 5 years?
This interview deserves all the praise it has had. Great great great. Justin and co are like the Elon Musk and Tesla of ebike tech.
So funny I replied the same response.. then read yours! Love this guy!
Justin is one of my favorite humans in the world. Honestly a huge inspiration to all of us and an incredibly kind and giving man.
grindz145 Completely agree, he (and his team) seem like good people working for the betterment of society. His views on open-sourcing innovation and avoiding patents was especially inspiring.
It was an honor seeing this video. Maybe it's time to pay them another visit.
At 42 minute onward, your software is great. Super useful for uneven landscape of Sydney Australia and many places with hills, cliffs and rolling trails.
The enthusiasm and passion that Justin shows talking about Grin Technologies had me watching till the end . Thank's Court for a great interview.
You know you're right. I hadn't thought of that but yes it's so nice to watch someone talk with unreserved passion about, well, whatever. I too watched the whole interview even though I had no intention of cobbling together an ebike.
I've know Justin for 15 years. I never get sick of hearing him drop some wisdom and inspiration. One of the best engineers and inventors I've ever met.
Justins business is a think tank for E-Technology. Definetly a genius in his field. Very personable and friendly.
OMG. I feel like I could unpack just half the stuff in this into life-missions for the next 20 years. So much fun!
This was an epic interview!!
Many thanks to everyone who made it possible.
Also, Justin lives in a bloody house boat and gets to build new innovative e-assisted solutions everyday!?!?
What a butthole!! That's my fantasy life :P
Justin really answered all the pressing needs encountered in the e-bike industry. Foremost holding manufacturers to their advertised standards lol. Justin’s discussion regarding battery performance was quite on point. Amazing person indeed! Here’s the kind of person who should be leading this industry. Grin is on my radar 100%! That’s a company who have their business set straight. Bravo!!!
My O My, I thought of skipping this video, but it kept me glued all the way. Thanks to Justin for being so inspirational and thanks to the video producers.
Fantastic time with Justin... the nicest and knowledgeable guy ever!!!! Justin is always creating the best gadgets and accessories that WE reeeeeeeealy need and no one is making!!! This is when Justing brilliant mind shines and we get something amazing to save our ebike lives haha
Loving this video... lots of people have been always wondering what happens inside Grin =]
Powereeeerrrr!!!!
POWAAA!!!
Totally agree, Bruno! Justin is an inspiration.
Chase, this interview is one of the best things you have offered. Firstly, I regret that I live on an opposing edge of the continent, but am pumped that such capable souls are cooperating in B. C. The discussion on battery management alone is worth the time for Ebike enthusiasts. Had you biked all the way there from Austin it would have been worth it. I am one who loves the self powered bike I have, so I will be getting in touch with Grin Tech. You are truly multiplying the service you offer to your community! Thank you!
James Jacocks Hey, thanks James! My name is actually Court, I don't say it too often so no worries on the mixup :P Glad you enjoyed this video, Justin and his company Grin Technologies are extremely interesting and good willed. This was shot on a Friday afternoon and he stayed late and completely opened his shop up. As we were talking some of the employees even said they learned a few things. It was a special day... long drive to get there but totally worth it :D
Court, I can be an idiot. Have a friend named Chase and that just slipped ...
ElectricBikeReview.com Wrap up ya shows with "My name is Court and you've been watching"...... Then we remember until ya next show. Ha.
U really nailed it all ! THANKS A MILLION !!! Craig R. DUDA, designer & builder
Absolutely amazing! I live in different part of the world but Justin's passion and the way he talks about technology is magnetizing. Thanks for doing this interview.
Justin, your grace and intellect have won me over. Grin Technologies will be my choice for the conversion kits.
This is one of the best interview I have never had a chance to watch....thanks! Justin is so enthusiast AND knowledgeable AND happy to share share his HUGE knowledge on ebike topics!
Give him few millions $ and he will become the 'Elon Musk of the electric bike world' !
This interview is the bible for everything DIY ebike for sure. Thanks Court for your interview and thanks Justin for your true pioneering, complete breakdown and crucial business model. Grins all around! Going on 4K myself :)
I don't know why autoplay is showing me this 5 years later, but I'm glad it did. Justin clearly has incredible knowledge and passion for this tech and hearing him go in depth about so much is a great listen. Would love to see more content like this in 2021.
20:23 it is called a "battery aging" and is a chemical process happening into the battery that depends on state of charge (voltage) and the ambient temperature. The higher the voltage and temperature, the quicker an aging happens to the battery. As a result, it loses its capacity.
Absolutely priceless interview! The amount of information and its quality... I would say, DENSITY, is so high. And that attitude! The eyes are shining out of the depth you all are into this field and mouth is too slow to deliver the length of the message you have!
Great thanks to you all, guys!
Suprised this hasn’t come across my feed sooner! Hello from Seattle. Endless sphere lurker since mid 2000s
i refuse to see movies longer than 1h , but seen this whole thing in excitement .
man i'm in love with electricity . and you guys are best thing happened to this technology !
What an outstanding interview!
I’m totally impressed with Justin & GRIN …. and Cort did a great job with the questions.
We need an update.
GRIN has a new headquarters & new products.

I am very impressed with your interview with Justin. I'm probably the age of most e-cyclist grandfather's.
In the late 70's I was a suit at McDonald Douglas Aircraft, Long Beach, Ca.
That was around the time I graduated from a bicycle rider to a Cyclist.
My first nice bike was a Pinarello full Campy/Cinelli/Omas titanium bottom bracket.
I spent most Saturdays at My Friends bike shop.
The atmosphere was like at Grin Technology.
Watching You video brought back memories.
I subscribed to Your channel today. Which means I will watch Your videos to completion and leave a thumbs up/ comment.
Continue to turn out great video.
R Mack an Elder Cyclist.
I'm building My dream e-bike it should be finished by My 74 birthday August 15th. If You like I will send you a video.
Right now I'm riding My
preproduction mule all the components from Amazon.
My parts list includes a Grin Technology cycle analysis v3.
I will end this before it turns into a book.

wow! Justin is absolutely mesmerizing. his knowledgeability is truly staggering. let's hear more!
I think this is one of the longest videos I've watched on YT and I'm not complaining. Great interview.
Putting this video in my library. Enjoyed this professor's very informative lecture.
WOW. What an amazing walkthrough. Watching and learning from people like Justin is truely inspirational, what a genius! What a genius!!
Knowledge, science, engineering, physics, with a smile. Nice! Thanks for teaching 🙂
wow I'm impressed with this entire operation!
One of the best e-bike videos I have seen Court.
I thought that I would watch it over several sessions but the time flew and it was over too soon.
Thanks for taking the time to interview one of the most interesting and inspiring characters in the e-bike world.
+Stor Apa Sure thing! I was also surprised how long it went when I began editing the footage... It was great meeting Justin and I'm so glad we could share this. Hopefully he and I will connect again in the future for more interesting videos and stuff :D
He seems so enthusiastic and passionate about what he does. It's great that he was willing to devote so much time to sharing his knowledge.
Justin would make for a great Auctioneer....his words per minute are off the chart! I imagine you could slow down the audio to half speed and he would still sound like a fast talker. great interview, great products. thanks Cort and Justin!
Justin and his team really helped me get over the mystery of ev bike components for projects. I am now researching for my 3rd rear wheel drive balloon tire bike build.
Justin is a very clever person and very interesting to listen too this was an excellent insight in to this mans brilliant ideas 💡
It's a shame this vid was so short I could listen to Justin all day he's the Musk of E-bikes.
Been watching your ebike reviews since the beginning and this was an awesome 1on1 of the Elvis of ebikes,.....this meeting-interview will send you to a new understanding of ebikes.thanks.
I highly doubt you;; get a better video out than this. Justin is the wizard, thank you for showing us the mystery within and it totally lived up to my imagination. Awesome
John Bozi Glad you enjoyed it John! Definitely one of my favorite videos so far. I agree that it was special, Justin is a unique character and his company and employees are great :)
Awesome video. As an entrepreneur I just admire the hell out of this company and it was great diving deep. Learned a lot of new stuff, too
I'm sure that was our friend from Tesla. You did very well to stay with him. Both of you communicate at a warp speed. Yes, a great interview. I'd love to send it to someone, but its way over most folks heads. Wow. Thanks for that culture shock.
Thank you so much! This is one of the most educational videos I've seen about ebike components. I'll keep Grin on my radar!
Over past couple of years I’ve probably watched this 4 or 5 times and seem to learn something every time 👍
Wow...he just educated me more in this video than all of the videos I have watched combined over the last year lol. Good job guys.
hub motors though , not a fan of hub motors
@@TheAgentAssassin He's talked about his reasoning for hub motors and I feel like it's pretty solid. The main one I remember is redundancy. Say your chain breaks on a ride, we'll you can still use the hub motor to get where you want to go. And same thing if the hub motor/electronics die, you can simply pedal the rest of the way to your destination.
This is the BEST Interview i ever saw. Just halfway in, but i am so stoked at the prospect of seeing the range simulater coming up ...
I salute all the initiative of making people learn and yes i did, partly thx to grin tec, motivated by the suntrip and also using endlessphere ...
Ultimately it was bikes that got me interested and served as some sort of gateway technologie into new interests, but it is people like Justin that keep me looking positively at this world and let's me enjoy learning without only asking myself why most people would still do things as they do ...
I am just building my own ultralight electric road bike and I sucked up every bit of new information presented here. Thank you for making this great video.
I use a small light weight front wheel hub motor with 250 watts to help me be faster on the hills. 250 watts is perfect for me because it is legal (in Germany), cheap (I bought a used ebike from ebay with battery and charger included) and durable.
Justin is officially my new engineering hero. Working in a corporation you get bogged down with politics and I envy his can do mentality. Sure sometimes you spend more time on things than you estimated, but having actually done things makes people so much more interesting. Kudos!
What a great video, so happy to see someone and crew who are open source minded and so crazy full of information and sharing thank you very much.
Thanks for this great video, your best so far! Justin is amazing, in his technical knowledge and skill as well as his willingness to share information without a profit motive.
ytesb1 Yeah, visiting Grin was a blast and I was really impressed with Justin, his coworkers and his family. Great people with an honest perspective :)
Great video to listen too, I have been working on ebikes for 20 years hence my interest. conversion kits i feel is best and so simple to trace any faults
First time I was in his shop I was picking up a kickstand for my dummy. While waiting I saw an electric unicycle on the wall and knew I was in the right place.
I thoroughly enjoyed this documentary, and learned so much. Having converted several bikes I appreciate the problems Justin and his crew are solving. Given, it is 5 years later, it was interesting to peruse their website to see the products being developed (in the video) now offered for sale. Also, they're moving/expanding to an even larger facility. Thank you, Court!
I'm only half way into this video - but this is the Most Incredible Tech Info session discussed.
The Key Points So crucial in this first half is the battery tech discussed on Charging Lithium to
it's best condition, and it confirmed pretty much what I had learned over the past ten years,
by the habits developed when using batteries whether for cordless tools, cell phone, etc.
Holy Cow - this was Seven Years Ago? - Now theTitle on TV - Aug 2015.
I thought it was yesterday when video auto-played on the TV. We Need to See More of
this Guy,, for Sure.
It's so enjoyable watching now on 55" Samsung pre-smart Tv through PS4 -UA-cam App.
vs Laptop or phone.
Cheers & Great Presentation
Bravo and thank you both for this great in-depth tech talk.jason's passionate brilliance is wonderful and welcome.a big thank you to you both for a job well done.Keep up the extremely good work you both so obviously care about.LET'S FLY E-BIKES!
Some people love what they do.... and it shows! Thanks
Whoa, and Wow and...more of this spirit. The ethos just falls right in with, I think most people. Wonderful, just really terrific. I can't say enough about Justin an his vision that continues. The world is better for it. No doubt about it. I am moved. There may be hope for us yet.
One of the best interviews I have enjoyed on your bike reviews. Thank you.
Nelson Olivo Thanks Nelson, I realize my actual "reviews" are repetitive and follow a set pattern, I love to learn and enjoyed this time with Justin. He went above and beyond to share openly and had so many interesting things to convey... it was amazing :D
Yes. I could sense it how interested and amazed you felt when he was informing you on his latest research projects. In this interview i could also see his passion to inform the DIY electric motor public
Bars and bars of geek chocolate. Great info and very informative/learning . Discussions like this will always be underrated .
I am surprised I never saw this before as I have probably viewed almost all your videos. What an amazing person and an amazing company!
Surf skateboard 58 years old I don't skateboard. No more. I didn't quit skateboard until last 48 I longboard down mountains. My friends do I don't. I hung with some of the best skaters in the world.
Your skateboards look so cool, because we do 70 miles an hour on skateboards. Down the mountain here in New Mexico. Time ship racing. People that don't get it. Think a bicycle can make it down the mountain faster than a skateboard. They're so wrong. It's the 2 will thing man. This video is I'm gonna have to watch It again. You're spittin'out so much knowledge you're. You're just encyclopedia, dude. Thanks for your info I subbed
This guy is my electric bike hero. been super inspired since that video if his ride across canada
If this eBike thing ever runs out of charge, I'd gladly subscribe to your 'Tech Talk Movers and Shakers' interview channel. A brilliant job Chase!
I’m feeling like I’m in a masterclass with this video. So much amazing info, please visit Grin again soon! This was amazing, thank you.
Justin knows his stuff. Valuable info. Great interview! Thank you.
Best video I've seen in a long time. So many interesting topics. Good work Justin! And thanks Court!
Wow - what a great smart conversation. What welcome surprise.
Grinn fits the name of this company. I mean this man seems like he has a permanent smile on his face! Seems like he would be a great person to buy from
Thank U Justin and team for endless sphere.
Love your charger it's the BEST!!! Thank you Grin Tech for the amazing charger... Hands down the best E-Bike charger I have ever used...
Wow! I'm loving your in-depth interviews.
Kevin McCue Thanks Kevin! I'm so glad Justin was willing to share this much. I realize the video went long (I thought about trying to edit it down but am on the road so time has been limited). Hopefully more interviews like this will come up in the future, maybe I'll get to re-visit Grin someday and see their finished product!
Totally blown away by this video mate well done - the best one ever! Massive kudos to a great ebike innovator how incredibly inspiring! The future of sustainable transport is so bright because of visionaries like this!!!!!
A nice interview. I'm glad I watched the entire clip to see the Grin office...
I love the talk about shipping logistics for battery packs, the absence of ebike shops (or regular bike shops that deal in ebike mechanics). My local shop said they can't get insurance for ebike repair (Philadelphia, PA). I imagine many bike shop employees still are 'purists' but that the insurance and a bunch of other basic practical considerations also contribute.
Epic interview, Court. I especially appreciated all the electrical talk circa 6:37.
I'll be listening to this again - it's that full of explanations and details. I was surpised by his dismissal of the mid-drive in favor of front hub drive. Justin sounded so scientifically unbiased until that point at 1:37:18
ForbinColossus Ha! Yeah... I really admire Justin and appreciate the testing he does but everyone in this world seems to have at least a dash of opinion. It's all good, we had fun exploring together and I think he received some of the alternative views constructively, even if he didn't completely agree :)
I think he had quite valid reasons for his bias for hub motors .
This video is GOLD!!
I find that it is good to fully charge the battery and leave it charging for 2 hours in order to balance . Do this after 6 - 8 cycles of 15 - 90% then use the battery right away ..
After use , charge when battery has cooled off upto 75% and finish charging just before our next ride .
Never leave battery full over night .
If you store battery store at 50 - 70 % and check after 3 months , if ok leave and check 3 after months .
If you stored for 6 months or more , fully charge plus 2 hours for balancing , and use within hours so it does not sit fully charged.
(Fully charged batteries degrade quickly if left fully charged .)
Batteries need additional charging time in order to balance cells . 2 -5 hours once charger light turns from red to green . This will not over charge but it will fully charge each cell .
Note Always be nearby and awake while charging . Most fires occur while charging.
If smoke happens ... unplug and move battery oudoors . If fire occurs unplug and use water to cool battery . Battery should now be properly disposed at battery recycler .
Do not use !
This is gold!
sweet baba ganoush....this was amazing..thank you
Just looking back, fun days. Still riding
1 Hour 44 mins ! Suspecting you love this place dude.
vibe2light Yeah, time flew... I felt so bad when I realized that his family was waiting for us upstairs. We just kept going! There were so many things to look at and share :D
Awesome interview EBR! but do some lens correction in post to get rid of that fisheye look... It's hard to look at for a long time.
I ordered from Grin before, they got back to me with answers very quickly and sell great products!!!
Wow, this is a total goldmine love it!
Loved every minute of this video, thx a lot from France.
That is an awesome setup and inspiring..
thank you Justin for what you are doing! appreciate it! one of the most informative video on your chanel! love it!
Artur Ragulskyi Glad you enjoyed it Artur! I learned a lot from Justin and was so fortunate that he was able to spend this time and go on camera :)
Wow! I am totally ev-geeking out! Fantastic interview/conversation...keep up the great and inspiring productions!
20 min in and learned SO MUCH! Great vid so far!
yes, yes, yeah and wow!!! thanks court that was amazing , I'm going shopping there very soon.excellent!
Early 1990’s when you went to the store.
Every box had so much technical information on the back of the box, it was so great. Some times it was funny because the front had marketing bs and in the back the engineering specs would tell you the truth.
What a great interview!
best vid you have done man. good job and i love the info and thanks for your time effort.
Loving this interview.
Very educational indeed. Thanks for sharing.
Sonnet Gomes Absolutely, glad you enjoyed it :)
ElectricBikeReview.com Absolutely Court. Now that I have watched the full video, I have to say, this hands down is one of the most informative videos on ebikes I have seen on youtube. Justin is very innovative and a very smart fellow. So glad to him working and improving ebikes and motor technology. I have used the Cycle Analsyst. It's amazing. I only wish the Satiator came with BMS capability. The biggest reason I dont use a BMS on my battery is due to BMS failures and unreliability of all the various BMS out there. Hopefully future version of the of Satiator will incorporate a BMS function as well to balance charge various packs.
WoW, on so many levels. Inspirational. Exceptional. So many gifts here. No words. Saved. Haw'aa
Justin testing is the best part >:) i don't share everything with es. if i lived close by i would love to work with you guys!
I agree one of the best in depth videos you've done mate. Brill from London
BEST INTERVIEW EVER IN EBIKING
Super informative show! A+ job Court!
Watching this one at work tomorrow!
Very interesting l enjoy Justin. A good proponent of electric travel.
