Hi Alan,
Thanks again for your help last September. As a result, I did receive a replacement for the defective kit from Golden Motor Canada. Unfortunately, 8 months into their 12 month warranty, the replacement kit has also stopped working. As you can imagine I'm not too happy with Gary Salo or Golden Motor Canada, but I will address that in a new topic.

Anyway, my symptoms are almost word for word the same as another post on this forum:
http://goldenmotor.com/SMF/index.php?topic=5950.0(Tgice, "Problem with Magic Pie 5")
We both got our kits in October 2015, both had identical problems starting within weeks of each other. The only difference being his was a MagicPie5 from lunacycles and mine a SmartPie5. Well, that is, Gary says its a SmartPie5, but the batch#/part# sticker on the motor would seem to indicate that it's a 4, here's the info:
Batch No. 20150625-IV
SMART4 VEC INT 18A V5.3.1
201506001549
so that's a little confusing...but ya, same symptoms as Tgice's post:
--Rode the bike between 100-200 miles and 8 months (Oct2015-May2016)
--In the middle of a ride I suddenly get a crazy, pinging sound and pulsing in power like I was jamming the throttle on and off
--Now won't accelerate from stopped at all, but if I pedal the bike first and then feather the throttle it will pulse and ping again.
I did all the troubleshooting, (I've been a jet aircraft mechanic since 2004, and have built 3 ebikes) same as last time I had a defective motor. It's not the brakes, it's not the throttle, (I slaved in an identical one from another bike I have) it's not the pedelec. Connected my laptop to the motor controller, no fault found in the settings or uploading/downloading them.
So, mine and Tgice's situations are eerily similar. I don't know how widespread this problem will get, hopefully this doesn't turn into a recall type situation. Although it does seem that lunacycles is unloading their SmartPie5 stock (two weeks ago the kits were marked down and selling without them even being laced them into a wheel first.) But hopefully it's nothing. Love to hear from you and/or Gary.
