The noise is mainly from the small 12t front sprocket that is needed to get enough reduction from the single stage. I have the small block single stage and it is somewhat loud compared to my Cyclone 3k. Not crazy loud, but louder than the cyclone.

Thanks Mike, I’m really enjoying the 3D printer. I got it right before Christmas specifically for making ebike parts. It has become a great hobby to get me through the New Hampshire winter. Like you, I have been following the 3d printer industry fir several years and finally felt the...

I taught myself Fusion 360. Still much to learn, but I fumbled my way through it. Can’t beat the price...free for hobbyists. For a slicer, I use a combination of Slic3r, and Simplify3D. I wish I could settle on one, but they each have advantages. thanks for the compliment on the...

My winter project was designing some 3d printed covers for the LR single stage. I’m very happy with the result. Printed in PETG on a Prusa printer. Next, I’m working on a seatpost mounted battery holder for the 12S Lipos I run.

I thought that may be the case, but I tried many of the hall phase combos. I found two that spun the motor fine on the test stand, but under load, the motor sputtered. One of these combos was what Mike at LR suggested, and another combo was found through experimenting. I'm going to junk the...

Just wanted to give an update about my controllers woes. I ended up ordering a Lyen 12 FET from Edward. I swapped it into my setup, and it is working great. No issues with motor sputter. I'm still using the CA3. I wish I knew what the deal was with the PV controller. I guess it was just a...

I replaced all of the hall sensors with genuine Honewell SS41 sensors. I tested the bike out and the problem is still there. Time for a new controller....will just get a Lyen 12FET. What a horribly frustrating experience, I just wanna ride! -Brian

I'm comfortable soldering and aquiring components. Is there a PCB available for sale. Also, is the firmware image available or would I have to purchase a programmed flash or CPU? I'm curious about this controller. Regards, Brian

I may have pushed the small block too hard on my mountain trek last weekend. When I opened the motor to replace the halls, I noticed some burnt windings. How bad does this look to you all? Should I just hit it with some high temp laquer? I think I may need the big block.

Hello, I nicked a couple of motor windings while replacing some hall sensors. Any suggestions on what type of coatings to use for touch up? I thought about clear nail polish but I'm not sure i will hold up under temperature. THX, Brian

Ok, so I tried bypassing the CA3 and ran throttle direct to the powervelocity controller. The problem is still there. At this point, I'm close to tossing this controller in the trash. I'm debating whether to replace the hall sensors in the small block with genuine honeywells that are on...

No, there aren't any settings that are timing related...just speed and power limits. I popped the motor cover last night and verified that the stock hall sensors are switching...they all switch between a few millivolts and 4.3V. The pullup resistor is around 2.7K. I don't want to pull it...

Hi, I am intersted in some simple solutions for 'blackening' my aluminum parts...brackets, etc. I know there are various poducts that will blacken aluminum through a dipping process, but I'm wondering if anyone has any specific suggestions. I have considered the duracoat and ceracoat spray...

I disabled field weakening setting and set speed to 100 instead of 130. It made no difference...still sputters under load and heavy throttle. Will test halls next and most likely replace since I already ordered some honeywell parts. Brian

I will try to disable the field weakening setting and also turn the speed setting to 100 instead of 130. Maybe they both advance the timing too much. THX, brian
