In my area, most shops do and have been turning down any motorized bike. But, times are changing, and some of these shops have intelligent, forward-thinking employees, who do see a real future in them. All gas bikes are currently turned down, because of the Florida Man that typically comes with them...
If yours won't work without seeing the battery, you could charge the battery it was meant for, then use that battery to run the boost converter. (even leaving the charger connected to the battery so it keeps running without discharging the battery too far). That would enable you to use a higher cur...
All right, I don't see how this wouldn't work, but may as well pass it by you guys as a sanity check. I have one of the affected Cycle Satiator 72v chargers that needs to go back for warranty. So, in the mean time, I still want to ride my ebike with a 24s battery. I have a 58.8v 3a charger, and I ma...
Please download the CA3 Un official Guide and take a look at "Appendix A. Calibrating the Cycle Analyst RShunt Value" . There are several means there of calibrating your CA to the controller shunt. This is written for the CA3 but is equally applicable to the CA2. Here you can plug your Satiator val...
It could be that the shunt value is wrong in the CA, I'm inclined to believe that the charger is correct. You could connect a Wattmeter to the AC side of the charger. Also you could monitor for how long it is charging with Constant Current, and multiply the hours times the Charging Current, to get ...
My cycleanalyst says that I've used 26 ah during a ride, while my satiator only says 16 ah after charging. What gives here? I'm inclined to believe my analyst, but both are from the same manufacturer. This is charging to 97v , and discharging to 87v , which consistently shows around 26 ah and 2400 wh.
Yeah, SBP has good stuff. I use both their HD motor 14T fw, and the $120 UHD crank fw. These mounts feel pretty solid. I can't move it around that much when pulling on it with my hands. So, I think it'll do well at the 2500w future power level. I do want to replace the black zip tie with another ste...
In case you didn't know, Raleigh actually makes cool bikes. But, you probably won't see them in a bike shop that uses them as a secondary brand. Or, they'd likely be selling these out from under the specialized/trek/giant/ etc that they carry. This is a 2018 Raleigh Redux 1 in matte blue , large fra...
The higher volts (ie. running 24s instead of 20s) should just allow me to have the power I want, at a lower amperage. Which I was hoping would be better for the batteries, and ideally possibly even better for the controller/motor. Wait a sec, from what I understand, it won't be better for your batt...
Yes, but $120 for a made in the USA, replace it once and never again item is what its all about! I dont want a failure at 1am on some bike trail in Orlando. Already been there. Cobrajet, the system uses two freewheels. One on the motor output shaft ( after planetary reduction), and another that thre...
Yes, the spring pulls it the opposite way, into the low speed gears. Works with any shifter of the proper pull ratio. For trigger shifters, you hit the thumb lever to up shift, and the trigger lever to down shift. Rapid rise is a little bit trickier to adjust cable tension.
Yesterday I had a guy in a roadie kit on a fat tire bike (training), riding with his wife on a fat tire ebike. So, he obviously couldn't have been opposed to the idea. But, the dude was having a good old time, continuing to fly past me and my friend at 25 mph really close, while we were doing 20 on ...
My god, the lines at the grocery stores, gas stations, home depots, etc. Everyone was in prep mode for 3 days before it hit. We didn't board up the windows, just put away anything that could become a missile, in the garage. And, let me tell you, it was frocking awesome. Wanna know what I was doing t...
Hey, thanks for the extra replies, everyone! I've played rather extensively with the ebike sim, especially with its new kv ratio adjuster. All things considered and simulated, the 7.5 Kv motor in a 26" wheel, with 89v nominal, 40a max, is the best match for my build. I already have the charger and B...
I'm just wondering why you chose 24s, if you only want to cruise 25, and have 30 mph max speed? My gut reaction is that you should run a 14s battery. I ordered parts before doing enough research. I thought I had it figured out, lol. The bike isnt built yet, nor are the cells welded yet. So, I can m...
Oh, that's right. It's a 26" wheel. The battery is 38.5 Ah, which is 11p of panasonic GA cells. So, I think 40a max peaks is no problem. The pack should be capable of 27.5a continuous, and 55a peak, if using the 1/4 and 1/2 manufacturer c-rating rule. The controller is rated for 40a , but that's ful...
I have a 35mm DD motor right now, with an 11.46 Kv. The battery is 24s, and will be run at 40a peaks. No long duration hill climbing, but it is 90F almost year round. I have the option to go for the same motor build, with a 7.5 Kv. I won't ever be pushing more than 40a , and I'm running 89v nominal....
Yeah, I won't ever let a kid ride my 4000w Talus (work in progress). I won't let some adults ride it either. I have to make sure they have enough sense to not crash or injure themselves. I understand what you all mean, by the standard "Do the research" reply to most inquiries. Nobody wants to contri...
So, yep, riding the ebike down the trail the other day. I pass 2 kids fishing off of a dam. One says, " Hey, is that electric? " To which I responded, "Yes it is" . And, I told him some stuff about it. Then, he had the guts to ask me if he could ride it. I responded with my rehearsed answer: " Yeah,...
I like the plastic cell holders that maintain space between the cells but those take up considerable space. For tightly packed cells, Nomex paper is good. It withstands high temps and adds abrasion resistance. Like this Nomex 410 stuff , here? What thickness would you recommend? Do you know a bette...

I bought 1,000 of those. We will be using them for sure!
Is there enough room left for wiring, padding and support around the pack, between it and the casing? This includes on either side of the pack at the cell ends as well as entirely around it to the part of the casing shown in the pic. Aha, I didn't clarify that. The pack will be well wrapped, and pr...
