Re: Elegant solution for 72v main power switch

I'm using one of these with my phaseruner at 72v and it had been working fine for about 6 months. I'm a bike courier that had to turn my bike on and off about 30 times a day and haven't noticed any arcing. Please clarify, is this on the battery supply line? :shock: Or just in the controller ignitio...

Re: Found an incomplete ebike at a thriftshop

That is a 9C or a 9C clone which can be a pretty fast motor and be used at fairly high voltage. Where are you located? If you were near me I would be happy to bring a battery and controller to test it for you. I’m in Arizona. I doubt you want to take him a battery and controller since his profile s...

Re: Cycle Analyst V3 preview and first beta release

heyDD- It sounds like a button or perhaps condensation problem that is causing phantom button pushes. In particular, holding the left button depressed on boot sends control directly to Setup - you primary symptom. Buttons not working is likely because one or more is stuck ON.

Hub motor bounce

I was wondering what would cause a rear hub to bounce? I put my bike upside down and hit the throttle and the entire bike shakes. Looking from above, the wheel seems pretty true, but I'm assuming it's not? Is that likely the problem?

Re: First build and would like a second set of eyes....

Personally I would find something with at least front suspension. The battery choice seems good and yes it has a lock. Since you're ordering from em3ev anyways, you might as well get the 5A charger. The option to charge to 90% will increase the life of your battery The blue gear will most likely be ...

Re: Cycle Analyst V3 preview and first beta release

I turn on my cav3 and it just says "setup". Sometimes it'll ask if I want to reset defaults, but the buttons don't work... What's up? It's cold, but not wet out and it had been working fine. Even today, I put about 50kms on it before it started to act up. First it changed my display screen, then ask...

Re: Vector Storm e-bike Frame 299€ / Parts WORLDWIDE

People , buy these frames, so that Artur can start selling frames ( light frame ) with a better swingarm, and with the main frame that has the opening on the side ( not bottom ) for the batteries , so that we can take out the battery pack each ride . I agree with the swingarm part, but I like how t...

Re: Compact Field Oriented Controller, ASI + Grin, limited run

Just a quick review of the Phaserunner: I had mine up and running quickly with my eZee 250 rpm with blown hall sensors. It configured a lot more quickly than I expected, and the 36V battery now tops out at about 26 MPH with up to 9 amps field weakening, which is a bit higher than I was expecting as...

Re: Cycle Analyst V3 preview and first beta release

Not sure what's up. I have a PR/CAv2 combo and everything worked great for the past few months. I haven't changed any settings, but now the used Ah on the display is waaaay off. I have a 52v battery that was charged to 56.5v and I used my battery down to 49.5v, but the CA says that I used 17.5Ah. I ...

Is it possible to enable regen without an ebrake or button? Like maybe just rolling off the throttle?

Re: Compact Field Oriented Controller, ASI + Grin, limited run

What would be an optimal setting for field weakening on a 1500w 4T leaf motor running a 14s battery at 40A? I have my phase amps set to 90A now. I'd like to get a higher top speed without really murdering my efficiency.

Re: Compact Field Oriented Controller, ASI + Grin, limited run

I've been running an infineon CAv3 combo from em3ev and it's been loud, but runs great. I recently bought a phaserunner and swapped out the controller, went through the setup and now my bike accelerates painfully slow (but amazingly quiet). I'm only running 52v 40A on a 1500w leaf motor. What should...

Thanks for the detailed response. I'll play with the settings and see what I can come up with.

Re: Bewo, New Crank-drive Motor

I'm only running 250w, but I just crossed 5000 kilometres on my cargo trike. Often hauling 150kg+plus driver and bike. Definitely s lot less power than my bbshd, but I'm quite impressed with the bewo. Zero maintainance, but I'll probably crack it open soon and grease the gears.
