" Nation,

We're well into a new build here in New Orleans, based on a 73 bmw airhead frame. Follow along here!

Need some help on how to wire the Kelly for Brake lever Regen. I ran release-throttle last setup, but want to free wheel. Can't figure out the wiring for this setup. Any advice?

Thx!

Short power wires...... "

" Welcome. I'm also new to this, and in the Columbus area. I'm project planning at the moment. My plan is to build packs from 18650 cells that I'm harvesting from medical packs. I'm in the research stage, looking at BMS options at the moment, and still trying to decide on if I want to convert my nicely running ICE bike, or if I'm going to pick up a donor frame to build on. A scooter build is appealing as well. Can't wait to hear more about your project. Alex "

" Hey y'all, I am experiencing an issue with my bike that I want to see if anyone might know about. I have very rough power delivery when applying throttle. It previously was very smooth and linear, but now it's very choppy.

My setup:
ME0709 (updated brushes)
Alltrax AXE7234
Domino throttle
22s Leaf cells

I experience it more at partial throttle, under 55mph- but it may just be smoothing out with greater intertia at that point, or when the controller is at 100% duty cycle. I plan to get into it later this week and see if there is anything obvious like loose connections, but I would appreciate any tips on things to look for.

I am slightly suspicious of the Domino throttle since I laid it down on that side and the throttle may not have liked the shock. I am going to try and find an old analog multimeter so I can see how smooth the resistance sweep is from 0-100%. "

" Weekly update,

Front brake mount designed,built and installed, Front brake lines ordered, Rear brake assembly ordered.

Battery mounts designed, welded up and installed. Body design determined ( we will do a wrap for this project)

It looks like we will have to shorten the motor wires. Good thing we kept the heavy duty crimper from the last project.

The batteries and controller in the photo are just in the bike for layout purposes. We will do a finally install after it is all wired up.

Thank you for the recommendation. A quick look shows nothing even remotely close to me unfortunately. However I did run across the Zev. It's not THAT far to go see one (only 300miles). Anyone have experience with them? The past financial shenanigans of the founder do make me slightly hesitant to trust the company. "

Hello, I only have one motor controller and the hub motors left actually. The controller is not high speed, its water proofed and has CAN, I think those are the only mods I had on it. For the controller, I would go $750. I had a guy who I sold the other one tell me that if you have a deal with kelly for OEM or production you can get this controller for $750 if I remember correctly. So I figure thats a fair price. "

" Just buy a full face lid with a pin-lock visor and be done with it. Only way to go, no more fogging regardless what the weather. "

Battery will most likely be shot unless it's already been refit - but the latter task would be the job you'd be aiming to carry out if you can nab one.
Save you a WHOOOLE lot of heartache, and they're a crackin' machine! "

" This may not work for you, but I have a motocross-style helmet- it's full face but I have to wear goggles. I have not had issues with fogging even at cold temps but I haven't ridden all winter (yet). What about a reusable dusk mask like people wear in Asia? If it forms a good seal that might work. "

" I have that problem all the time during cold, wet, or foggy weather. There are lots of anti-fog chemicals on the market that will help some. But they do need to be reapplied before each ride. I also have one helmet with the Pin-Lock face shield system. But that requires a helmet face shield that comes with the pins that the Pin-Lock attaches to, which typically is on the more expensive helmet brands. Plus replacement Pin-Lock inserts are not cheap!

Since I have been dealing with this problem for 55 years now, I continue to try different solutions. Just about any of these solutions, including a breath deflector, works to a certain extent, but what works the best for me is to crack the face shield slightly and put up with a cold breeze on the face - which can be mitigated with a scarf, or something similar. Of course, once finding a solution to defogging the face shield, if you wear glasses you end up having to keep them from fogging. "

" I used to ride through the winter. I was never able to completely eliminate fogging but I had limited success with using some form of breath deflector. In the winter that was usually my scarf that I wrapped around my mouth and nose, then down around my neck and into my jacket. Not sure how effective that will be with a full-face helmet though. "
