Re: New 4800W Cyclone?

I am Going to the mid drive for increase torque and top speed, and reduced unsprung weight with the motor being at the front of the swing arm instead of out at the end of it. This is the bike you want to convert? Or use as comparison for the mid drive build? I’ve come to the conclusion that a good ...

Re: 2020 Giant Escape + Bafang BBS02

An alternative to thru axels is a solid axel. You can get them from ebay, wheels manufacturing or AliExpress. I’ve even been able to swap up to 10mm dia in the front up from 9mm. I try to stick to metric 10mm x 1mm thread pitch. 3/8” is available and prob ok if you use matching nuts. I use the nuts ...

Re: 36v , 48v , 60 v , 72v 40A BT programmable e-bike brushless controller

Can the regen level be varied while riding? Continuous adjustment, or a set of levels? This is a good question. Only seeing this on the Nuclear controller so far. I’m sure others have it. If you can see a controllers wiring diagram it shows a simple ebrake that’s kills the motor. This opens or clos...

Why don’t you order from AliExpress? $170 for the 1000w, $350 ish for the 3000w. 1000 is belt, the others have chain sprocket for a motorcycle

Re: Cyclone 4kW mid-drive self-engineered project

Thanks for posting your build. Love the aluminum hollow box frame. One question is the controller supplied in the kit the 40 amp or 60 amp versions? What one did you get with your kit specifically?

Thanks

Re: Rear Sprocket 125T for #219 chain (LMX+Kart)

I’d like to purchase if devo doesn’t respond. Do you have a PayPal account? I’m in the United States. I’d like to try this one and see if it works then decide on ordering more. Is the center mount bolt spacing typical for a kart sprocket? Good to know this please.

Here it is now on Amazon. This must mean something if Amazon puts faith in selling some of these. I know it’s a drop ship and they just get a cut but still. Old style Motor case though.

Re: QS 3000w midmotor

hello, be careful the 12F is able to provide 10kW peak. There it is 10x the nominal power of engine. You'll tell us what it does. I have a QS 3kW and it will turn with the Thermonucular 24F. I'm eager to see how he run. I preorder this from June. Thanks for the heads up. I will start out with extre...

Re: QS 3000w midmotor

Really interested in these motors from qs, does anyone have any experience with the 1000 and 2000w versions? My 1000 has been really happy at 3500w, around 8:1 reduction with a 26in wheel. I don't have a temp gauge but will bump it to 5000w once installed The motor shaft is 17mm nontapered so the 3...

Re: Am I asking for trouble? BBS02 on carbon road frame

Opinion only here. If you keep the weight down and don’t crash you should be fine. A steel frame will survive most crashes to some extent. Cracks from crashes and stress can be welded. All other frames types may give you one or maybe two crashes and your frame is unsafe or just broken beyond use. If...

Re: Need advice on motor, battery, controller, for overhead cable car

You’ll probably need some sort of reduction. Most motors spin say 3000 rpm and you need say 300 rpm for an ebike to work properly and not burn out your motor or controller. For your project you may need even more reduction to keep it slow and powerful. Lowering the final rpm increases torque in the ...

Re: How to select motor and gear ratio for mid-drive?

Just get a benfang or cyclone unless you have very little to spend. Your time spent figuring could be time spent mounting batteries etc. and preparing for riding using a kit where the engineering is done already. Keeping power levels low to keep costs down really isn’t worth it. Many think 250-500 w...

Re: qs 1000w builds

Glad you got it going! And with the nuclear controller too. Did you get the 12f? I gave up my space in line to free up funds for my workshop expansion going on now. I’m hoping the controller is a success and readily available down the line.

Good to see some states have the financial resources to enforce such crap. What’s next a regular boat registration for a kayak? I hope this is only for the city and suburban types because it seems pointless in remote areas.

Re: qs 1000w builds

It’s not a hub motor. Doing the math of kv x volts to get rpm is a very low number at 11kv. Should be a number in the thousands not hundreds for rpm. I’m thinking kv of a motor rating is just that and has no relation to the reduction. I’m considering selling this motor as my projects have changed fo...

Got it. Any opinions, anyone, on the belt vs chain versions? 8mm wide for the belt seems narrow. Also the belt has a fixed length. So if going with the belt driven and no swingarm your motor to wheel distance is fixed to the belt length, a pain but doable for a custom builder, but your reduction rat...

Re: New 4800W Cyclone?

Or a pogo stick why not.
Seriously. Opinion only. The big box enduro frame design is tired and overkill. An alternative is a departure from this frame.
