I have heard that... just not experienced it as we tend to travel in the towns and cities.

I'm quite the fan of talking beavers... especially when they are friendly.

Quote from: Geoffrad on May 16, 2024, 11:16:47 AM... As i read the manual i see that it is probably best to use a RAD charger because it is designed and optimized for the RAD battery. SO i am buying the $70 one from RAD, i guess, if i have to...

That may be your safest bet.
I have a Benchmark electric mower and a Radley drill & impact driver. Both take batteries that look the same, and have the same voltage and Ah spec. They can fit in each other's chargers, but they won't charge. If you swap chargers, one says it's a defective battery, the other doesn't even "see" that there's a battery. The Benchmark battery works in the drill, but the Radley batteries won't run the mower.
I suspect that the BMS and/or the chargers have some kind of chip that prevent mixing the brands, possibly out of safety concerns, or possibly just to force you into brand loyalty. (As it happens, Radley and Benchmark are both house brands of the same company, Radley being the budget brand.)

I have no idea if any brand of ebike battery and/or charger does anything like this, but you never know, unless it specifically says "this charger is compatible with this these batteries ...".

I agree with this, I see CrappyTire puts it on sale frequently. A simple multimeter will help you isolate where to concentrate your troubleshooting.

How is your riding style? Do you use mainly the throttle? Granted I have very little experience with an e-bike but I assume it will take a lot of effort to burn up a motor.

I may be misreading it but you said you hired a professional to install the upgrade. Therefore when they were done I assumed everything worked fine.

Now that I have a few kms riding my City+, I can comment regarding the hills of Burnaby. I grew up near the Royal Oak hills. And I used to work near BCIT on Canada Way. I have ridden my bicycle on those hills a lot. I now lives in Calgary and have ridden hills comparable to Burnaby and I must say that they are doable with the combination of PAS and the right gearing. I do not mean to compare myself to you but I said it to help understand where the problem is. There is a big area to troubleshoot between the battery and motor.

why not use extensions? they are available.

Share a screenshot of your settings- I'm happy with mine but am curious to see what you did. Thanks!
