Would like to see more on this bike, looks like fun.
Super fun bike, I actually ended up buying a second one...
Where did you buy it ? This thing is amazing!
@@HolmesHobbies LOL when you kept saying in this video that you 'don't need' another SR I kept thinking to myself "Holmes sounds like he's trying to convince HIMSELF." LOL I just knew you would not hold out. I was really lucky to be one of the people who got one of the first 50 X controllers from Luna. Great regen and sine wave. Apparently a number of those test X controllers failed so SR made a change that is very different on the one you got. The engine braking on the first 50 feels like a 125 two stroke in third gear when you let off the throttle. At around 5:25 on Matt's review of the controller you can see how much went back into the pack after a very short downhill. czcams.com/video/f-hY30xl-rs/video.html
Apparently SR shut down that amount of regen because a full pack going downhill would overload the pack.
so still a really cool eMoto, shown in a great video, done by an awesome guy
Thanks John, love your reviews on the bike.
This video, and my other recent readings about Sur Ron, make their engineering seem pretty sweet! If I got one in San Francisco, the hills here may argue for a bigger back sprocket as you've done.
Although, the difficulty you found when pulling power cables out of the battery reminds me of the lockable battery on my Haibike -- the securing fasteners are not _that_ strong, so for longevity just roll the bike inside, plug in, and avoid all connector stress.
i'm still very happy with the bikes. I would agree that san fran hills would be a good match to lower gearing
Larger rear sprocket means MORE low end torque.
Brilliant review.
Your problem wire that is tough to remove - there looks to be the possibility of adding a strap loop underneath inbetween the 2 caps and you can pull on that
Very informative, Thanks John
Ha ha ha - how is that "not buying another bike" thing working out for ya? Great reviews man. Keep em coming
Brilliant reviews, txs John!
Try upgrading the bike with asi controller and better battery that could be made from your 2 batteries. You will get a lot more power
@12:10 you mention that the larger gearing makes the bike feel flat in the mid range...simple reason why is because with electric motors, the more load, the more the controller puts power to the motor, thats why in comparison to a gas motor, electric motors fall off the faster they go, and in this instance, you have less load because of the larger sprocket hence in the middle of the range you would have less power....Sorry I put this comment down before watching the rest of the video..you explained it better than I did...lol
I know it's not related to this video...but I thought I would post it here to get your attention. The dyno/motor work you did was really interesting. I know from the comments posted...buyers wanted to see certain motors and comparisons. I hope you gratify us with an upcoming video on those. I have the luxury of having almost the whole Holmes product line, but for the consumer who is holding off on an upgrade because they're confused on getting exactly what they want, the info would be really beneficial. And in related terms, I know I won't be adding to my collection until I see some sort of proof that say a Magnum is going feel and act SUBSTANTIALLY better than my three crawlmasters or Puller pros and I can get visual reference to values and test numbers. I hope that makes sense. Thanks John
All my new motor vids will have dyno charts. I haven't circled back to the magnum yet, but it's on the docket. The only trouble with dyno information is that it doesn't convey the 'feel" of a motor, which is IMO the most important part for rock crawling. It will show the magnum having more torque density and power, but won't convey the snappy yet smooth feel of the large rotor. They are like a brushed revolver in many ways.
@@HolmesHobbies Thanks for the response. If I could see that a magnum and my revolver where close in specs, but without the noise...I'd be picking one up! Keep up the good work.
Well done, very good presentation, thanks for sharing.
Loved it!
Hmmm.... With what your talking about regarding loosing mid range punch after gearing down, is there an easy way to spot that phenomenon (esp with a new ebike build).
Great review as usual John. But where is your front brake? I've done 1.500 miles off-road on my sur-ron during the past year and i agree with you, great quality. I have replaced/upgraded some parts but the main components of the bike are rock-solid.
In a box somewhere. I'm going to put some nice breaks on it soon. It's just being used for shop errands at the moment and no offroading.
I'm fine with range and weight but power is only 65cc power witch I could live with but too expensive. The 2350 from factory. Luna adds another 1500. If they offer it with both sets of wheels and tires and better controller and some better suspension, or a controller and a extra battery. not to mention their price on parts or much higher than what they are in Europe virtually unavailable here. I do like their upgraded controller though Cindy had off of Chinese websites easily 2600. Same Luna warranty that Luna has to back up because they are there at US Distributors distributor
Ik this was a year ago but the surron x stock is equivalent to 125cc not 65, modded with new speed controller and 72 volt battery it's equivalent to 250cc
Great vid man
More electric bike videos!!!!!
Will try my best. I'm certainly passionate about them!
If you were upgrading the Surron fork. What size would you use? Great Surron vids, easy to understand.
Any downhill fork. Boxxer is what I have on there now, it handles fantastic.
Yo! Nice. So, you lost the headlight and sensor mess? Where did ya put the wire cluster? Is everything under the controller? Does it run normal without the display? Im thinkin of ditchin mine. Ita a 2 yr old bike
Great reviews John. Dumbass question: is EP mode the same torque (up until cut off) as Sports mode? Or is Sport quicker acceleration even at low speeds?
What did you pay for the basic bike you first ordered? I really am impressed with you’re reason for improvements. Thanks for sharing.
3200
2 years later they are $4200! 😲
The camera seems to be focused on the tree....which is kinda weird
John, have you heard of Onyx hubs? They are billet and top quality bicycle hubs. Also, the highest quality dirt bike hubs (way more weight) are cast. I don't really know if anyone forges hubs on bikes.
Hey John, thanks for this long term review. When I did a podcast with Eric and Matt I could not for the life of me remember how I came upon the Sur Ron. But after watching this video I remember now that it was YOU who introduced me to this bike. THANK YOU THANK YOU THANK YOU!. I actually wrote about that on my Sur Ron blog. Glad your leg has healed too. Take care and stay healthy.

Glad you like it! I felt it was a video I had to do considering how major the bike release was in the electric market. Still loving mine.
@@HolmesHobbies almost 4000 on mine. Gonna have it cremated with me so the kids don't argue about who gets it after I'm dead. Just gotta tell the crematorium to remove the battery before starting the furnace!
does that one have the bypass the sports mode button to get the top speed higher?
Hello, you really mixed things up - only thing that Field Oriented Control can give you is a precise motor control (less torque variation, less vibration and noise) and possibility to choose right motor control strategy. For example, if you need speed, it can give you more but will sacrifice torque (btw this control strategy is called Field Weakening), or maximizing torque (MTPA strategy). FOC also better utilize available energy (few percent higher efficiency), so you can ride slightly longer.
Anyway, it's a nice bike. Next year I am going to buy one. I want to build something like this, but I change my mind.
Best regards.
FOC can help more when the motor bEMF is sinus. 6 step commutation with sensorless works fine for trap bEMF motors. The efficiency gains are normally had over a basic sensored controller that cannot do zero cross commutation. Such as the old Xie Chang controllers. FOC helps greatly compared to them! But compared to an efficiently designed block commutated controller and trap motor, the FOC does not always win due to switching losses . I have not tested the bEMF of this motor.
bro u look 10 times better in this video with that style lol, no hoomoo haha
Where's your curious neighbor?
You removed the front brake!?
did you do the cut/connect wire power mod? mine seems slow...
Mine was first run and it was in high power mode from the factory.
How tall are u
Holmey your crazy get a kevlar leg protector or 2 man! Love your vids though. I'm in Span! Its a Sur Ron made in China. I need a batteries. Can anyone point me to a supplier?
wait, you still don't have front brakes? (75% of your braking power)
nope!! Its 100% in a stoppie :) I'll get back to it.
Damn good video John, be careful with the rydin fun!!! I have a question kind Sir. I'm a Big Man, at 15 i was 225lb and did lots of W8 training, 3 sports in High school, my ??? Is this, I'm 5'10" & 268lb at age 52, still a brick house, I've been contemplating a Sur-Ron X or Perhaps a Segway 260?? Should I pull the trigger on 1 of these ebikes??
Or just be happy on my HD monster 👹 I thank you for your time kind Sir. Peace ✌
wouldn't be a problem for your weight. if you do a lot of off road riding you could gear down a touch too.
What's the weight limit?
not really sure, it pulls 240lbs well
Thanks for the great update!
Question:
1.how tall are you? I ask because I'm seriously thinking of switching from my 125 2 stroke trail bike to this and I'm worried this bike will feel really small.
5foot9
im 5eleven and it feels good seat could be a little farther back..
Hey John,
Wondering if you've seen the ads in FB Marketplace from some company (didn't catch the name) selling the sur-ron bikes for around $400? They look exactly like yours,
I know it's got to be a scam. I know you paid way more than that. I'd like to get one, just have to save some money. Love your videos, keep up the good work. 🤠🇺🇸☝️
@Spam Sandwich found it.
Guess it's a scam website, knew it was to good to be true.
Yeah I’ve seen those too, some weird Arabic site, definitely a scam
You can buy it from alibaba.com and then pay for shipping
no bobber seat mod yet?
Broke my knee in January and haven't had much ability to fab since.
KILLER ,NC ❤👌..... ...👍
Where did you learn all this?
Trial and error, and working with electronics over the past 25 years. Been building ebikes for 10 years.
@@HolmesHobbies I envy you
not legal on the road in the UK us and Europe were do u take it 20 m battery life of road hard or 40m on eco on the road at the most good for a kid to use off road to small for most adults.
With a regear to reduce top speed and keep it from putting down over 3hp, its road legal in my state.
I thought John Holmes made vintage porn?
what a renewable whiner!
Hớ much
T
not bad for a cheap chines bike to slow and to small for most people and to slow not legal in many western countries on the road or paved areas, my old motorbike is faster in first gear
I can't believe you just advocated cutting the front brakes are you kidding me? This brings into question your ability to advise people properly about a two-wheeled machine
I don't actually think he did. He did this for himself. Was it smart? No. Did he tell anyone else that it WAS smart? No. The front brake is the most critical, but like he said, his bike. Also his life. If he told others it didn't matter then I would agree with you, but he didn't.
How tall are u
