Hi All, I've just installed a brand new Minimal G310 Rear Hub Kit from Grin and it has died twice. Both times within 5 kilometres from my house (3 miles). This is all the mileage the kit and this build have on it.
Kit:
G310 hub
Baserunner Z9 controller
B3624LiM battery in DP9 Reention case
Throttle only
Symptoms:
- Clunk-clunk-clunk feeling before it dies (like a dead battery)
- The clunk-clunk-clunk is intermittent and happens at random times (easy flat sections or uphills).
- Rear wheel does not want to spin backwards (such as when pushing bike around)
- If I do spin wheel backward by hand it also makes a jerky clunk-clunk-clunk motion/feeling.
- Battery lights show 3 green and 1 red (like a full charge). But after first break-down the battery took a full multi-hour charge, so I assume it was dead.
- Battery lights showed 1 red after it was fully charged.
- Bike ran great after battery recharge but broke down second time a similar distance away (4.3 kilometres this time).
- After second break down I tried to charge it again. Charger switched to green after a few minutes and battery lights now show 3 green and 1 red after charge.
-There is a bit of silicone/goop leaking from where the motor wire exits the hub. this was not there when I assembled bike.
I also tried loosening the axle nuts to see if that would help the wheel spin backwards and it did not help. I also removed the disc caliper completely, and checked for any other rubbing.
Symptoms seem to me to be similar to a dead battery, or an overheated motor. But it couldn't be overheated after such a light ride (all the bargain bikes zip by me).
Any ideas?
Here's a picture of the bike and the goop coming out of hub.
I've ridden the bike very easy and the first ride (last night) was mainly downhill or flat (but not as nice coming home with no motor).
Today's ride had some uphill but I was easy on the throttle and the problem began almost right away. Motor has stopped completely now. It may turn on and offer a weak micro-horsepower attempt but that is it. It stopped completely on the ride as if it was turned off.
