Rumour has it that a blank/uncut Honda motorcycle key will work. I don't know if this is still true.

Thanks for coming back with the explanation.

SOLVED!
I believe I solved the intermittent motor cutout. After checking all the connections I pulled the rear wheel off. I opened the hub and a small amount of water came out. I believe this was causing the HALL sensors to reset the control...
I cleaned the motor, gears, and hub with a can of parts cleaner, a wire brush, and electrical-clean spray and regreased with red lithium grease. I did several miles this morning and it seems back to normal. If anyone else is having the motor intermittently shut off open the hub.
I bought the bike used so maybe the previous owner washed it before I arrived to purchase it...

Does anyone have this key? Rad customer service can't seem to cut a key replacement for me. They've shipped me a blank key 4 times. I will pay for this key if anyone has an extra of the same number. Could also use it to have a locksmith cut the correct design then I would ship it back to you.

I can't comment on the seat hitting a trunk bag but I have put the Suntour SP 12 NCX on my Radwagon 4 and it works great. I had to use a 30.8 mm shim but I have had it on for more than a year and it hasn't slipped or moved. It is an excellent low cost suspension seat post.

That's excellent DickB. Good data.
Thank you.

Regarding charging to 80% vs 100%, here is the best data that I have.

I bought a used second battery some time ago. The power connector had overheated and melted. The owner couldn't repair it; so I bought it as a spare and replaced the bad connector. The owner said she had put about 4000 miles on it, which I estimate to be no more than 150 cycles, maybe less. I just tested that battery today.

In the chart, blue is my original battery new, and green is that battery after over 300 charge cycles to 80%. Red is the second-hand battery that was charged maybe 100 - 150 cycles to 100%. Remember we are talking about complete charge cycles.

Most consider the battery to be discharged at 42V, where power drops off. We can see that at 42V the 100% charged battery has lost about 2 miles in distance capability, or about 10%. Not huge, but measurable. It will likely degrade more with additional charge cycles to 100%. I would guess at 300 cycles the loss might be about 20%.

Remember this test is at full throttle with a maximum distance of 20 miles. If you use PAS and pedal 40 miles on a charge, you would likely lose 4 miles.

It is noteworthy that power is not reduced, only capacity or distance. If you don't take long rides, you would never notice the difference.

did anyone ever solve this? I have a RadRunner2 that has power loss. I have run it with lights and brakes disconnected and get the same intermittent issue.

Were you able to fix the power loss? Mine does the same thing.
