BBSHD vs Sur Ron, Side by side comparison video
Вставка
- Опубліковано 22 сер 2024
- Bit of fun here comparing the performance of a modified BBSHD (ASI BAC855) running at 4kw peak and the Sur Ron at 12kw (ASI BAC4000). Both bikes are being run over the same short test route. Despite having three times the power the BBSHD is not disgraced by any means taking the switch back corner with considerably more grace. It would certainly beat the pants of a stock Sur Ron but is outmatched by the modified version!
This is an incredible test, and really shows the surprising speed of the HV modified BBSHD setup. With the significantly lighter weight too, it's pretty enticing.
We get lots of people say they enjoy them more than the Sur Ron because you are not a target for the police and you can easily limit the bike to meet the street legal rules and regulations where you live.
@@HighVoltageKits That makes perfect sense to me! I don't personally feel like I'd have any problems where I live with actual enforcement. But as far as pedestrians and other bicyclists that I see on the trails, it's nice to have an e-bike that looks as much like a bike as possible. Some people are just looking for reasons to be mad. Lol
Yup Karen's everywhere mate.
@@HighVoltageKits So true!! Lol
Actually to promote the HV kit a Stock BBSHD vs BBSHD fitted with a HV kit. 🤔 A steep hill climb would blow folks away what the HV kit can do!
100% agree! Great idea for a promotional video. Prob best to wait until they can get some stock though 🤦♂️thankfully got my HV kit last May and it’s just incredible!
It is a good idea. I mean there is a ton of footage on the channel when I first got my BBSHD plus stuff at 52 volts and 72 volts. Side by side might be hard unless I can find a stock controller lol. I'd do it if it was easy. I will keep it I'm mind tho for sure! Cheers
I don't even know what to say as really my First thought is that "EV good". The SurRon is logical knowledge of the whole electric two wheeled concept but a bicycle is so random to suddenly become that fast. Great modding mate.
Thanks. Its pretty nuts what a motor can do with modifications. I'm just about to upload a quick update on my personal bike which is where this channel began 4 years ago!
What are the weights of bikes and gear ratio at speed? BBSHD @ 65# 42T front, 32T rear sprocket
Surron @ ?
54t on the Sur Ron. BBSHD is about 65lbs. The Sur Ron us twice that roughly
TY for weights and showing motor RPM's. 12,000 peak BBSHD vs 7500 Surron, @ 8K vs 5K cruising speed.
I'm very impressed the BBSHD can rev that high with Power. TY again for showing an Ultimate Bike build.
Thanks 😊
After 6months of waiting all my parts are in the house.. EGGRIDER , STURMEY ARCHER, BATTERY BLENDER, MAGURA BRAKES AND STUFF...
This Week i start rebuild my Mario 20 inch Bike🥳
Wish me LUCK 😅✌😃
Awesome 👌 Good luck. Let us know how you get on!
Great video👍🏾👍🏾 You should do a do a comparison with a stock surron if possible
Thanks mate. Pretty certain it would beat it comfortably. I dunno we have a stock controller. I'll see what can be done. Cheers.
LMFAOOOO, that is crazy impressive for the BBSHD...
I will have to try F.W. set at 50 (instead of 40) with 42T to 42T (1:1) gear ratio to see the speed I will get on my bike...
It was spinning at close to 20 000 RPM when I tried this with wheel in the air.
(It blew up the PAS sensor board at that RPM, LOL, new one on order...)
Great job to all the High Voltage team
Cheers
Dan
Cheers Dan, long time no hear. Hope you are well! Holy smokes on the PAS board! 20k is the most I ever heard!
@@HighVoltageKits ya believe me, it was spinning scary fast... still lots of snow on the ground over here, but summer is coming and have to install New PEEK gear on my BBSHD and fix the PAS and a couple other upgrades... Can wait to try it out.
Cheers
Speed would be less. A lot of unnecessary heat and a lot of stress from vibration
@@eXTreematorprobably motor's rotor itself at 20k rpm
so the dedicated motorbike style e-bike won ? imagine that ........ 🤣👌
Yeah although it would beat a stock Sur Ron!
@@HighVoltageKits stock for stock? i mean i get it, the sur ron is kinda the be all an end all of e-bikes but it's really not a fair comparison, it's kinda like comparing a race car to a road car even still thanks for your videos been learning heaps..
How fast are you spinning the Ultra with your testing with the BAC? Pretty keen to get a kit when available! The larger rotor/stator should make for some tasty powerr
I think it was hitting about 6.5k
This is a stupid presumption. Larger rotor and stator just based on size of materials make no difference on power. Just like bbs02 is exactly the same theoretical power as bbs03
I’m gonna want a BBSHD HV one day!!!!!!!
Sounds good! Cheers
Great comparison! It would be great to see how "BBSHD + bac855" 72v vs "CYC X1 bac2000" 72v ... would compare!
Yes that would be cool. Have to see what we can arrange!
@@HighVoltageKits Great ... so the video is coming
;)
I'll do my best!
Not that much of a difference in acceleration and power but the RPM's are almost 50% more at times though. That's a lot of wear on parts.
Its remarkable how well the bbshd holds up to this kind of abuse. It truly I'd an amazing little motor and it's a shame Bafang won't take it to the next level.
the difference i should say, it's really noticeable 🤣
I never had any thoughts about it being that close. It certainly takes tight corners better tho. It's on the hill part where the extra 8k of power is more noticeable.
You really hit 85 with a BBSHD BAc 855 ? Damn.. the most i've got was 76 and not as quickly... I do run it at 3500w though. Still there seams to have a big gap.
Yeah! That was a slight downhill. I have hit 78kph on my fatbike and that was on a downhill. Some of it will be down to gearing and the wind resistance. We have worked on the tune for a long time. Its really quite optimised now. On my bike it peaks at about 65kph on the flat with a 1:1 ratio. It is a fat tire bike. Lots of people using our kits have kit 80 on the flat with lighter hardtails.
Can you make a comparion with a cyc at 5kw vs the surron
I don't have the bikes to do that. These guys did tho. I made the controller mount for the BAC2000. It beats a stock Sur Ron but not a modified Sur Ron ua-cam.com/video/pUOr6ZcYIus/v-deo.html
what does sur Ron even mean? because in french it means "on Ron (as in sitting on Ron)" and I'd like to think of something else everytime I see the name :P
That is as good an answer as any. Honestly I have no clue!
Impressive from the ASI855 & BBSHD.
What kind of battery amp current and max phase are these running?
BBSHD have any other mods, steel gears, etc?
100 phase, 55 battery. It has a PEEK gear but thats about it. You can see the full video here with some stats displayed in terms of how much power is being pulled! Cheers ua-cam.com/video/ttVPZBSEW3o/v-deo.html
@@HighVoltageKits How does the 55amps from the battery translate into the 100 phase amps? I guess that's exactly the job of the controller, but I have no idea how that works... Lol
whats the total price of each though ?
So this is just a ballpark figure here. Alot depends on whether you use new or second hand parts and frames or build the battery yourself or many other factors. But in USD I'd say you could build a nice molded bbshd bike for 4k. The Sur Ron would be more like 8k by the time you are done and dusted. This is to hit the kind of performance you see here. The builder of these bikes did much of their own electronics and battery work which lowered the costs. Hope this helps.
Man jesus. Sometimes i wonder if i really need a hub.
Nothing wrong with a good hub mate
Did you pedal as well? If not, bad test.
I don’t understand. You can’t pedal a Sur Ron.
@HighVoltageKits the bbshd, I believe it wouldn't be a fair test if the bbshd wasn't pedalled from cold start. Surron hasn't got pedals, bbshd has. So for true speed, you have to utilise the entire power available for each bike. Since sur hasn't got pedals, it could potentially be equal.
@jakebaked5996 Ahh ok I understand. In this case though it’s a modified bbshd so the speed at the crank is about three times peddle speed under throttle. It’s not like with a stock motor.
@HighVoltageKits OK, I also see what you mean. Though I feel extra pedal power might have given you an advantage still. Everyone trying to de restrict theirs and there's me trying to tune mine down to appear legal power for UK roads.
Second :(

i think i saw you the other day geek while i was sitting at a stop light, yeah you were on a bus licking the window ....... you "special" little thing you ........... 😆
