Re: Raleigh Redux 1 + Cyclone 3000 + 14s 30a

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...

Raleigh Redux 1 + Cyclone 3000 + 14s 30a

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...

Re: new cyclone 3000 w mid-drive kit?

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...

Re: new cyclone 3000 w mid-drive kit?

All right, just to make sure, the best freewheel upgrades I can do to the cyclone 3000 kit are:

1. 14T motor fw : http://sickbikeparts.com/electric-motor ... -duty-14t/

2. Ultra HD crank fw : http://sickbikeparts.com/front-freewhee ... eavy-duty/

Sound about right?

Re: Rapid Rise Rear Derailleur

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.

Re: Is a lower Kv motor better suited for my battery?

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...

Re: Is a lower Kv motor better suited for my battery?

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...

Re: Is a lower Kv motor better suited for my battery?

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...

Is a lower Kv motor better suited for my battery?

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....

Contributing to the Ebike Addiction of a Minor

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,...

Re: Final thoughts on battery pack, before welding?

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...

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.

Hey all, here's the best arrangement of the cell layout of a 24s11p. What are your thoughts, critique, opinion, based on your prior experience?

Re: Raleigh Talus 1 Ebike Build

Okay, cool.

My friend did a test fit of the cells in the battery box. They are not in the correct format for welding in the pic.

And, it looks like a 24s 11p is going to fit, with the BMS, too. So, 89v 38.5ah nominal. Good for 130 miles @ 20 mph!

He was definitely a commuter going home. Lectured me about that road crossing being too dangerous for my speed or something like that. Yet, here he was, ready to pass me with no audible signal. And just speeds off! That's not how you talk to people, lol.

Re: Have you noticed that some drivers, purposely move over.
