That's awesome! I'm glad you like my video! Just wanted to clarify that the first video was from my very first test ride with the 750W BAFANG HUB MOTOR still installed but not connected. The extra weight of the motor definitely presented a challenge. To address this, I've already swapped out the wheels for traditional ones to significantly reduce weight and lessen the strain on the motor. I'll be creating a new video soon to showcase these modifications and hopefully help others in their builds. If anyone needs the JP40 can be purchase on my store. Check my channel for more details. Feel free to ask any questions you may have, I'm happy to share my experience and insights. The bike is still running great
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.
@@chriss2295 Except for bad tolerances, gritty bearings, cling film and bits of metal under bearings, delamination of ipm rotor and distortions in ipm rotor lamination stack. Received two defective ipm rotors.
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.
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.
I've put about 400 miles on my gen 4 with absolutely zero issues so far. I can put 6kw to it, but rarely do. I generally keep it at 3 to 4kw. I love it. The app makes it so easy to dial in. I'll take it over a Surron because it's stealthy. It just looks like I'm riding a regular e bike, but I can go 50+ mph if I want. I suspect I could hit 55 or even 60 but have no desire to.
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.
@ definitely will wait. I’ve found hub motors to be the sweet spot for me. The silence is really the key winner compared to a mid drive. However for efficiency and power mid drives take the 🥇
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.
@Hybrid600 there is other footage on TH-cam of lads doing this and keeping up with surrons this was with the gen2 also and 72v battery, gen4 is a lot more reliable
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 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
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.
Also for the clip you've included i ran a 1:1 ratio nearly hitting silly speeds for longtime never ever overheated not once..plus you reviews are always going to be biased when your selling kits for the bafang
No bias. I presented the information. Never even mentioned Bafang or the kit we do. Until the high power setups reach 2000-5000 kms with no maintenance needed it’s a big question mark. Im not the only one asking it.
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.
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.
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.
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 don't recommend, x6 controller, it gets overheated and limits your power, i have gen3 and Gen4, I have no issue with them. Following report, except the chain tensioner, have to replace it every 6 months, all mid drive motors cannot use throttle. all the time , it's not made for that of ride, mid-drive will give you better Weight management, controlling the bike much easy, especially for emtb, that's when you get the best experience, but one of the major thing is to keep the temperature down using higher voltage.Will bring the amperage down, would you gonna generate less heat, also using high-performance cells with low internal resistant, to bring the sag down, another important part is to have High quality derailer, like this, on my boat bike I have Sram Eagle XO, and Sram GX DH 7speed, my chain never skip, that's one of the things that it damaged, you're drivetrain, or yo motor, generate the water heat, especially when your chain is not line up correctly. Soon I'll be posting videos like my friend Nelvick the first video owner, and we both have the same fat tire ebike. You can check it on my channel.
Thanks for taking the time to post this. All sensible advice. I guess they still need to work on the chain tensioner. I think something that screws into place rather than relying on a spring might be the answer there.
There are not many folks running it at over 3000 watts. Those that are have precious few miles on them. So in terms of reliability with high power it’s not proven. Once Neil’s hits the 5000kms mark with no parts replaced then you can be more confident. If it starts wearing out parts quickly and needing replacement hopefully those people will also be honest enough to say so. I hope it’s solid but the last four or five years has been otherwise.
@HighVoltageKits why I mentioned gen4 onto my second build now, bought since release on my first build ran it constantly above 4500w not had a problem yet, there are many others that have done this it's all over forums
