CYC, you guys have just raised the bar again! Love your work, great team. Good job guys
The ability to mount the motor in the frame triangle makes a very compelling case for this.
Raises the center of gravity. You would feel it in the handing. This is why integrated motors from Bosch, Bafang, Shimano etc are still down low.
@@MHH3180 but seems vulnerable to strikes!
@@obsidian66 seems so, but ot has not been a problem and all new frames, with integrated motors, still mount the same.
One of the nice things about diy is to do it the way you want and with that op...
thats great !! finally a light option!
If the reliability is solid on this system, you've got a potential bbshd-slayer here. Torque sensing mid-drive bb motor @ 750-1500 watts with flexible mounting options looks fantastic.
Can you make a BELT DRIVE version? That would be even quieter and less maintenance!!
Belt drive could be a relatively easy retrofit since the cog and chain are external
How would you get the belt on to the bike you are converting?
No. Issue with a belt drive is maintaining belt tension on a rear suspension. Also for off-road the belts aren’t as good as a chain drive cuz of mud and debris affecting the function. A hard tail would be doable but again u need a frame that can be broken to put the belt thru the rear triangle. Unless the rear triangle design is such that u the belt doesn’t have to cross the rear chainstay
Is there a comparison video coming up anytime soon? I mean the most important factor, which is the noise produced by the motor. I have already decided to go for CYC motor, but since your release of the stealth version, I am not sure which way to go. Knowing the difference in terms of noise would help a lot with the decision-making process :) Thanks!
same situation here!
can it use the iscg05 mounts ? and wtf is this square taper crank it's 2021 ? can i use backpack battery and what is compatible ,a lot of guessing here, i'm just about to pull the trigger on the liftmtb kit, much more info on their site
The bike is solid and my Ebike conversion went great. ua-cam.com/users/postUgkxHL1v1R3NE5x4KiYfyt8dnQmyNYz7qi5L Very smooth ride at 30mph with no problems (135 miles ridden so far). The picture is a bit deceiving - there is WAY less space in the center of the frame than it shows. The suspension connection takes up the entire thing. So I needed to attach my battery on the bottom of the frame and my controller on the top. Instructions for assembly were lacking but honestly it wasn't too hard to figure out even though I have very little bike knowledge. Watched some youtube videos on adjusting the disk brakes but that was it. Still, I am loving it and very happy with the purchase.
your link ain't showing any ebike bro
Cool, but you mind making a 2nd version which isnt as whiney and loud?
Is graphene batteries safe to power this kit
Hello, would you plan to make X1 Stealth for 100mm BB (fatbikes)? Thanks
Debating rn on to cut it down or find something bigger
Hi, I have a question regarding the combination of CYC stealth with ASI BAC 855. ASI BAC855 is kind of a powerful controller, I understand that you set up some limit in the software in order to avoid overheating the motor, right? If it can run at 72v, 2500 W is done easily with as low as 35 Amps, while BAC 855 can give 50% more continuously and about 150% more burst power. In other words, isn't BAC855 a little bit too much of a controller for such a small motor? While it seems a perfect fit for your standard 3000W motor version, since while running at 72V it is exactly 50A continuous amps needed, I feel like you overdid it here a little bit, especially since ASI has e.g. BAC 350 or BAC 500 controllers (50A / 70A respectively) - wouldn't they be a better fit? If you could elaborate on why have you decided to go for such a specific combination of motor and controller, I would greatly appreciate it.
The motor can utilize almost all power of BAC855. In terms of the phase amp, the motor can consume all 90A phase peak from the BAC855, and giving out continuous 150N.m. at the crank while not getting very hot. the motor would just get warm in 1.5-2kW real life loading. Of course the X1 PRO will run even cooler at the same loading condition, but the heat of this system is not much.
The overall efficiency is >90% in this system. It is a very efficient small motor that can output a loads of power. BAC350/ 500 is too weak for this motor for full potential and we think it is the best to just offer a better controller (Also to ensure the durability of the BAC855) and people can limit the power easily via the app if they want to. Unlocking the power would not be a problem as the motor will be protected in time if it gets too hot (Seldom in real life even with very long steep hill). There is a temperature sensor embedded in the motor and controller respectively.
@@cycmotor Thank you very much for a prompt and detailed response :)
Could this be mounted flipped, so the motor drives the cog on the left hand side. This way you could keep all the gears on the rightside?
no, the motor drive force doesnt go through the bottom bracket crank axle. There is no way for it to drive the chain from the non drive side as the motors drive gear and the bikes drive gear are fixed together on the drive side of the bike.
What's the speed limit?
Does this engine provide assistance as the pedals turn like the Bafabg BBS02?
Yes. The BBS02 uses a cadence sensor & the PAS level (1-9 oe 1-5 or 1-3 depending on the display/programming) to determine the amount of power you require. This is fine but not as natural feeling as a torque sensor. The torque sensor measures the force you're applying to know how much power you want. The CYC motors have both cadence & torque sensors.
que precio tiene
Will this fit a 2019 aluminium frame transition patrol ?
yes
@@mattkruger2909 thanks with the price of the kit compared to the paradox kinetics kit I can get extra batteries .🍻
Yeah great motor design but crap controller that thing needs scrapping and redisgning on a single board for clean mounting.
Are your motors sensored or sensorless?
Sensored
Where can I buy one now Australia no more 8 thousand for a fancy piece of metal from bike company give me this thing
Im a newbie, i have no idea what is BAC855 and BAC2000 means, anyone understand that ?
controller
@@tmho7091 thank you
Продай такой мне?
I wish folks making videos such as these would rethink their sound and music, especially the volume. An e-bike doesn't make the angry whine of a motorcycle being revved. If we were in the market for that,, we would not be looking at e-bike conversions. While I'm at it, remember most viewers are watching on a smart phone. Tiny print that scrolls away fast is annoying.
You are raising your center of gravity mounting inside the triangle. It will throw off optimal handling. This is why integrated motors still have not moved this direction. As for ground clearance, it is an answer to a question nobody who has ridden a mid-drive is asking. It is just a non-issue. Your chain ring is always going to be lower.
The placement of the controller where it is most exposed, regardless of position, seems questionable, but if well sealed might be just fine. Adding an extra exposed cog and length of chain not so much.
