    Are my expectations as a customer just too high?

    I agree. If you can, try to get your money back and go elsewhere. The seller has told you they are shipping it soon and didn't, 3 times... Completely unacceptable. That shouldn't even happen once.

    Cargo Bike, Mount battery under Front Box

    Just wondering if anyone has tried what Riese and Muller did with their Packster second battery option. Battery is mounted under box, protected a little bit by the box overhangs. Anyone opinions?

    Power Oscillations / Hunting at higher speeds

    Turns out that it wasn't the CA, but instead an incompatibility between the controller (25A Grinfineon) and motor (TDCM_305_IGH) I got from them. Justin was saying that everything worked fine in sensor less mode, but not in sensor mode. He'd be able to explain in more detail I'm sure. He also...

    Power Oscillations / Hunting at higher speeds

    Sorry for not being more specific: Yes, I'm talking about the PAS->StartLevel. When I had the PLim->MaxPower set to 1000 watts I didn't feel any surging. When I set the PLim->MaxPower to 300 watts and used the throttle I did feel the surging as normal. I'll try that. Do I need to use a...

    Power Oscillations / Hunting at higher speeds

    I've tried the bypass mode. I didn't get any surging. But it was using full power. I also noticed on the diag screen that it was pulling 24amps at full throttle. That would seem to indicate that the rshunt value is correct. Is it normal for this surging to occur? The lower the watts, the lower...

    Power Oscillations / Hunting at higher speeds

    Thank you for your help so far. I really appreciate it. 1. What is your battery voltage? 52V 2. Which model motor do you have (305 or 395rpm)? 305rpm 3. Does the surging also happen when you run with throttle or only with PAS? At higher power levels (1000watts), no. When I set the max...

    Power Oscillations / Hunting at higher speeds

    Thank you for the direction so far. I'm sorry, it's not AutoPAS. It's labeled as "Basic (PWR)" under PAS -> PAS Mode I'm running 3.12 I guess I was just reading on Grin's website AutoPAS everywhere. I've checked the Diagnostic screen and it's only showing a capital W when it's happening. I...

    Power Oscillations / Hunting at higher speeds

    I recently bought a kit from ebikes .ca: - TDCM_IGH_305 - 25A Controller - CA3 - 12Pole PAS I'm having issues with it hunting to find a wattage. I've set the autoPAS to give 300 Watts when activated, no change at different RPMs. I have had to pull Wgain down to 5.00 so that hunting didn't...

    Converting my Bullitt Cargo Bike

    The reason I am probably going to go with Grin is because I can pickup the kit as I go over to Vancouver a couple times a year. Which will save me on the expensive battery shipping costs. Thanks for the vote of confidence. :)

    Converting my Bullitt Cargo Bike

    Thanks everyone for your replies. I've done some more reading based on your thoughts. I'm probably still going to go with a DD hub, rather than a gear or mid drive. Mainly for the regen (though I might add it later) and for keeping the wear off my drivetrain (vs a middrive). Looking at the...

    Converting my Bullitt Cargo Bike

    Hello, I've been reading a bit on getting a kit for my Bullitt Cargo Bike made by Larry vs Harry. I've been commuting for about 8 years now on my touring bike, and I also have a road bike that I do some racing on. The cargo bike is fast to bike around empty, but gets heavy once I put anything...
