Hub motor burnt in 2 weeks !! Help!

[ElectricBikerland]

I purchased a 36v 600 watt wheel
conversion kit w/ 12v 12ah SLA
batteries from We R Electrfied.

I rode it 2 & from work (18 miles one way)
3 times and the hub stopped working

the commute is 90% flat and on a bike path
w/ one moderate climb going 2 work.
and a harder one coming home
(that I usually walk, cause I ain't in shape yet )


I have a new wheel now ( due 2 the warranty),
but was wondering about the longevity
& durablility.

Now one factor may Be weight,
the combined bike/rider weight
is at the 300 lb limit and I was
hammering the ride 2 work,
(AVS 17 mph) would this be
a factor in the hub failing afer
only 120 miles?

Or do I just have 2 be delicate with it

& maybe losing 20lbs would help also

The wheel should last as long as the bearings last or until you get hit by a bus (no jinx) or it locks up with age and you try make it run for 50 seconds or more.  In kind the brushless design should  love you a long long time.  Sensors are a little wack, but IMO they seem to last fine.....  Unless you have a  catastrophic failure don't worry man.


Remember! If it stops turning find out whats up before you burn out coils or controllers and stuff.

Enjoy.

It doesn't sound like you're stressing the motor much at all, so I'd doubt that's the issue. My rider/bike weight is about the same, and I think it's got around 500 miles on it this year (my speedometer quit working and I'm too cheap to buy another just yet). Your commute even sounds like mine; I go about 6 miles each way, and a set of 7ah batteries get me one way pretty easily at about 20mph with a little help from me.

That said, losing the 20lbs isn't a bad idea! I've lost about 25 this summer, and it's nice not lugging that extra poundage around. Earlier this summer I gave myself a good lesson in why I ought to make more of an effort to lose some weight, quite by accident; I bought a 60lb bag of sand for a project at home, and carrying that bag was not easy. On the way home my son and I were talking about something that brought up the subject of weight, and it suddenly dawned on me that my weight at that time -- 245lbs -- was exactly 60lbs higher than when my wife & I were married in 1986. If putting that bag down was a big relief, how much more of a relief would dropping my extra weight?

Trouble is, losing weight is a lot harder and a lot less fun than gaining it.

Oh dear this thread ...

I was getting fat, 87 kg 191lbs.  I gave up the pain killers I got hooked on trying to manage a rare arthritic psoriasis condition, I still get the bone aches and migranes now but I use NSAIDS instead of opioids.  I dropped about 22kg 48lbs and now weigh a total of 65kg 143 lbs in about 3 mths.  No fun at all really.  But I feel nimble once again.


NEVER AGAIN!

Thanx for the response

Yeah, the one reason I
got this hub was so I could
commute 2 work more.

The 40 mile roundtrip on
a regular bike fried my legs
and I was only good 4
one ride a week

But with this kit I hope 2
up it to 2 or 3 times a week.

I should melt off some
Lbs then
