Riders this was LOADS of work I hope it's useful, Any questions just ask

Sam, great video (s) , I really appreciate the efforts you put into them. Your channel and website is a great source of information and provides E-MTB fans with what they need to make a decision. In case a new bike is not on the current "to do" list, watching your videos is still amazing entertainment. Thanks from Germany.

Great video, really appreciate the effort you have to put in to make this test happen.

Great test again Sam ✌⚡ love that u mentioned the differences in bikes specs etc...👍⚡

Great Sam, really appreciate this real world test. Pity your sit bones though!

My height is 190cm and my weight is 82kg, I have a Megamo Crave 05 AL with Shimano EP8 with 630wh battery, I have never drained the battery but I have done 2 times in eco mode all the time, 61-62kms with 1500mts+ and the display still had 2 lines of 5, i am sure that I can do 15 more kms of range if they are not more. I'm very happy with this bike and his range.

Great test! I’d like to know the difference between the Giant Syncdrive PW-X3 and the standard Yamaha unit in the Haibike Nduro7?

Great video as usual Sam !

Good review, just brought latest reign + haven't ridden it yet so good to see positive feedback. My current bike is Shimano powered and whilst I like the natural feeling motor the range is terrible and I have 504w battery and ride eco mostly..

Giant's new Syncdrive is really good. I can confirm that.

Wicked review Sam!! I got my hands on a Reign e+2 about 3-4 weeks ago....and I'm absolutely froffing it!! Funny you say it feels like it does the work for you, I basically never go above level 3 and only use level 4 on the steepest climbs or late in my rides. Interesting point to note, the top spec Reign comes with a 720wh battery....would be interesting so see how it stacks up directly with the Bosch!

Outstanding. Great information.

Looking forward to this review

Great test, thank Sam

Awesome test Sam! It’s a pity that most new exciting bikes are with the shimano ep8 motor. I would love to see a bike like the new Scor bikes (Awesome bikes IMO) with the Bosch motor.

Giant is a winner all round ,from distance to the best value for money 💰 🤑 💸 👏 👍 👌

Fantastic test Sam. I am very dissatisfied with the range on my Merisa E160 10k...som much so that I am actively looking for a way to swap haha

good to see not too much in it with the top 3

great video. been looking at getting these bikes my self. for those who want a move scientific way of looking at efficiency, here is my workings with the average watts per KM (WPK) (lower is better). EP8 @ 27 WPK, Giant @ 23.43 WPK, Brose @ 22.66 WPK and Bosch @22.94 WPK meaning the most efficient here is infact the Brose ;)

It’s more for the gravel biker slash commuter rider . These Emtb on eco mode on road in bog stock trim my E160 9000 limited to 25 showed 197km range around Brisbane bike paths

Great job! Have you tried the bofang motors are they god or bad?

Sam, genuine sacrifice in the pursuit of science ;-) As you say it’s hard to tell what other factors may play, however seems the trend is towards the Yam, Bosch and Brose which were all close. Have to say if you’ve e done 2000km on the Brose battery it’s still delivering in heaps after many recharge cycles. How many miles had the Giant and Mondraker done ? As we know batteries do loose their range over time. Keep up the pain !

Sam from my experience the specialised levo isn't reliable, because of water ingress in motor or wiring or tcu. Probably ok in hot climates thou, just no good in blighty.

Second question is the speed on all the bikes the same .The EP8 25km speed restriction drove me insane trying to keep up with friends on other brands. Had it derestricted from 25 to 35km .now no problem almost crashed trying to clear a gap jump and the motor cut out on 25 it limits the bike to much on clearing jumps .since I got it changed the jumps are not a problem.

Just a question was all the bikes in full turbo or boost mode for the entire ride .I have the EP8 in my merida and hardly use boost and say 40% trail the rest of the time echo.I still want a good workout 😁😁

Love it Sam great work as always and especially doing math put them all on 750 watt batteries. We all forget stuff at trail head and improvise, last year I was so excited first ride of the season forgot my helmet

After lapping your favorite DH trail over and over, back to back you should make another video comparing all of the bikes on how they descend

On my Merida e160 which is set up mullet with a 2.5 29er assegai exo+ max terra front, 2.6 27.5 butcher black diamond with cushcore in the rear. 625wh battery on full boost i did: 25km 1100 vertical m 1:31 min moving time.

thank you ❤

With my ep8 I did 3595 ft of elevation with 2 bars left at bpw !

Wheels giant and bosch 29" ,brose and ep8 27 5,+ rear traction 1 giant 29" battery 650 w 2 bosch 29" 650 w 3 brose 27,5+ 750w 4 ep8 27,5+ 625w =example more battery more climp + more big wheel more range ..

does the engine overheat in the sun and heat?

Hi, I watched few of these tests, yours might the best (most objective since you've drained the batteries), but didn't find anyone testing panasonic motors (fyler bikes f.e., a swiss brand). I rode one as I was lookiong to for good quality used e-mtbs, and it felt super good... strong, snappy, smooth, but can't really say anthing about the range.

Superb content Sam! Some many variables apply that's what makes it so interesting. My EP8 Orange Phase only runs the 504wh battery & I never struggle with my 630ah Bosch riding buddies. They complain that the power in Eco on the Bosch system is pretty much non existent. The EP8 in Eco is excellent....... It really surprised me! Keep up the good work.

I was going to buy a yt and only comes with 450...now im scared

Yo You may have to get power meter cranks or pedals to equalise the tests Stay safe

Lo del motor es a gusto de cada uno tengo una specialized turbo levo 720 de bateria y una ORBEA Rise con 360 y con las dos e llegado justo en rojo , ruta 68 km desnivel 1880 y son diferentes motores si te gusta dar pedales la Orbea y si te gusta subir en moto la turbo levo pero lo que me a sorprendido de la Orbea el consumo y que las subidas casi imposibles que hago con la turbo levo con este motor limitado a 60nt lo e conseguido y tengo probado todos los sitios , diferencia necesita cadencia pero sube y luego en los llanos puedes ir apagado la bici es como una muscular no lastra el peso 19,10 con pedales y la turbo levo 23,40 , son mundos diferentes .

Could the colder weather have affected the results of the SyncDrive and EP8 motor? I saw a test where the Giant motor had far more reach than the others …

So I've had an E8000 and now an EP8. RANGE HAS GONE BACKWARDS! The E8000 does 1,300m vertical in my local loop in Boost, the EP8 - 1,050 m. It's a massive disappointment. You simply don't expect the next model of a product to drop 20% performance in a key area, you expect at least the same or better. I wonder if the manufacturers knew this when they selected the EP8? I recon not. I'm guessing the problem wasn't picked up until too late and now, nobody wants to talk about it. It is what it is now. But to Shimano, many people are well pissed. Legally, you wont and probably shouldn't admit it. But do not kid yourselves. It's not a secret. It's an elephant in the room. Many EP8 owners live with this issue and will, as a result be very reticent to buy an Shimano equipped bike in their next model. They will definitely ask if the range problem has been fixed. To the bike OEMs - get independent motor testing completed prior to motor selection. This will hurt you too, particularly as the technology develops and range numbers are published.

What red mudguard did you gave on the silver/white giant?

Sam a touch off subject but I have seen 5 channels including yours introducing the Kellys Theos F8 almost a year ago .It was supposed to be the big debut of the Shimano motor and Kellys revolutionary new carbon material and the bike looks sic AF. However nobody did a follow up video to showcase how the bike rides. You; Rob Rides; EMBN and a couple other channels all did an intro video and nobody followed up with a review on the bike. Do you know what's up with that? Did you get a chance to ride it? I would love to hear anything you know about it because I want that bike if I can even get it in the US.

I just want to note that you were 20% slower on the Giant than on the Mondraker and Levo. The levo and Mondraker avg. right at 17.16 and 17.2mph respectively while the giant averaged 14.29 mph. The EP8 averaged 15.45 mph, so the Giant had your lowest avg speed. I think thats a massive difference in speed between the Brose/Bosch and the Giant. As some one who has the Brose, Bosch CX and EP8 and RS variants I was not at all surprised by the range test. I have the Giant in the same spec coming in and I was curious to how it would do. I do wonder if the Giant is slower to get the better range.

Hi Sam, what smart display did u use? I may have missed it.. thank you

Thanks for all the hard work on this! Boy I just look at all these new bikes coming out with the EP8 motor and can help but wonder if shimano's going to do a complete redo, better be back compatible as well. Do you think the Bosch is still the most powerful punchy motor out of the group?.

I knew the Yamaha would win all being even 😎

So close I was 20. Maybe next time

And there iz bafang????

As i know, the "stock" 630 Shimano Battery is not that great in the range sector and third party Batterys work better with the EP8

👌🥳

It is quite wierd because shimano doesn't feel as powerful as bosch for example when tackling steep sections but even so it has the lowest range...

The range is atrocious in them all. I was considering buying one but forget that, I'll stick to my manual.

The problem on shimano ep8 is some bike manufacturers use crap cells

How does a riders weight change the range? What about the fat guys lol! Can't all be 12 stones soaking wet! 😅

But you can’t get a 750w battery with all of the motors, so doing a calculation for all of them having a 750w battery is irrelevant. The original conclusion is correct. They should be measured as they come when purchased, not IF they all have the same battery, because they don’t. Otherwise, good test!👍🏼
