True that.. I’d like to upgrade especially to an isis spindle.. but damn I’ve got 30000km on my bbshd and all I have done is grease the gears every yr.
@@WilliamCloud9Seems like only few are complaining about bad BBSHD OEM bearing quality in terms of seals. Found some metal bits and cling film left in the bearing bores of nylon gear shaft alongside gritty 16003 bearing. Will see how skf, fag and nks will hold up especially if used with 10 000 rpm using field weakening at 72V.

Really glad to see comparisons against prebuilts. I feel a lot of sur ron channels distort their videos using the fish eye lens to make everything they do "more exciting" and "faster" than it really is.
New gen 4 owner. 9 mile shake down on the bike super impressed with the 3kw 60v power. Simple install the motor barely got warm to the touch on test ride and temps barely touched 40c. I live in a place with quite steep but short hills.
Thanks for the video and info. I have a gen 3, went thru a motor and a controller in the first 4 months, but it's run good for a year since those failures. Since the motor failure I've limited it to 40 mph (a magnet coming off the rotor caused the 1st failure at 45 plus mph).
I went with a shimano 5sp IGH & 24t r.sprkt. (coupled to a CYC 38t chainring option), I know the torq rating of each but have not done the calc. I tend to be conservative because my best guess is that the hub will *almost* handle it, but have no doubt if I (scotty voice) "give it all she's got cap'n" the hub would explode. That in mind I also know it doesn't like low rpm under heavy load so I cruise @ 2000-3500 rpm. Usually
I run mine on an 8 spd, but only use the throttle on the 26t where the chain line is perfect (it'll skip on others sometimes). It's all lasted a year so far.
Holding up fine. Only run the throttle wide open at 3500-3800w for short bursts. Maybe a minute at a time. Mostly just peddle assist where I’m using 750w max on trails. Not a lot of hours on it. Not anticipating much problems if I don’t overheat it.
It would be nice to see a test of the Gen 4 on a proper full suspension bike giving it a proper thrashing offroad with steep technical climbs and rough terrain. That's where the reliability (or lack thereof) will really show.
Neils has done this but there is no footage of it sadly. It will do that for sure. The question is for how long and in the past parts have broken pretty fast from this kind of treatment.
I've been watching the temp gauge on my Gen 3 Stealth this past summer. after 160 F, it starts to object to throttle input. So I've had to be real careful of gear selection especially when riding off road.
I definitely think I will hold on before I buy the GEN4. It would be great to see more videos in a year or so time to see how they’ve held up, especially the ones that were using 72 V batteries. Four minutes going full throttle is good however I don’t like the fact that it will reduce it down to 2 1/2 kW when it gets over 57°C. Again with the gen three there’s been that many that are blown up and fried it makes you think do we need to wait for the technology to improve you clearly pointed out there is many small parts within the motor which is the downside to it so there will be lots of maintenance compared to your likes your BBSHD.
I have a hard time navigating the website and finding purchase options for the M635 kit. Where is the "form"? Also, where are you supposed to get the motor ? I can't find it online.
in my experience there are trade offs with a BBSHD modded vs. the 72v Gen 2 CYC X1 Pro I have. Interestingly they both are using BAC855 currently, but the HV tune and mods to the bbshd makes me feel more comfortable sending it full power lol. Both are hitting near 4kws near peaking power
@@HighVoltageKits not yet lol. I'd like to have my Ti Frame bike have a similar battery as far as cells are concerned. A 2025 project for me to look into. Both bikes are able to go more than 40mph easily
Not a modified one in my opinion. Not for reliability or noise. Technically it has a bit more power now but I don’t think they will last long at 6kw. I’m prepared to be proven wrong.
There are quite a few videos on this channel running through what I did with my bike. We also have some offers on our kits at the moment which is the best in the industry. Each one is custom made to order and you can make contact with Greg@highvoltagekits.com to order anything.
Does the Gen4 motor have a smooth keyed shaft coming out of it or a gear? I'd like to use one on a non CYC project but none of the pics show the shaft.
I'm just doing my build now, only I have the Gen 3 motor with the Gen 4 controller, I'm a heavy basted too, so who knows how long my motor will last, but I don't think I will be pushing 6kw continuous, would only be short bursts, even 2.5kw would be a stretch run any more than 10 to 15 seconds sustained, I actually like to pedal as my usually trek is over 50km's, no battery that fits a bike will last that long at 2.5kw sustained with 130kg rider, will be interesting though ass my Bafang Ultra has been rock solid, all the chain and running gear has been destroyed many times, but the motor has been brilliant, if the CYC fails me, I will be looking at modding a BBSHD instead.
Sounds like a solid plan. Keep us posted on how it goes if you will be going up to 6kw. Try and gear it to let the motor spin up to higher rpm’s than you see on the bike in the video.
@@HighVoltageKits I'm running Gates Carbon Drive on it, with a Nuvinci N171, so ratio's are limited, but the front is about the same as a 36T so ratio should be fairly low.
Watching this video makes me love my BBSHD even more. I’ll take reliability over power any day.
Yeah. I have huge kms of zero hassle riding on mine.

Amen. Been running my bbshd above 5kw about 2 years now. Rebuild the motor to have real thick gear oil instead and magnet below

How’s it holding up. What power are you running it at?

@@HighVoltageKits offroad is the real test. With lots of load and on/off throttle usage it puts more strain on everything of course.
@Hybrid600 agreed

That’s pretty hot. The stealth is built in the same way as the photon with an outrunner motor.
@@HighVoltageKits you said in the video at 4:32 that 74c (165F) is not that hot for motors.
Any more feedback on reliability for the Photon motor since have yours repaired?

I bet the BBSHD is a lot quieter than your CYC
Is this the Photon?
No the x1 gen 4
So is this cyc better than the bbshd now? Or not?

There is a shaft with a key.

@@EEE-iw3fk is it only the x12 then? Yeah the x6 ought to pair well.
