Hi all.
i have been working on a new project much closer to my long (long long long)
time goal of actually building electric vehicles.
i got fed up with CALB (another long story that i have avoided posting but
may still yet...) and wanted to find a decent LiFePO4 battery supplyer and
came across a factory near my adopted home here in China (Guangzhou) but the
largest format they make is 20Ah packet cells. most of what they produce is
for toys and e-bikes.
i had been telling a friend ( another foriegner here ) that i was going to
build an electric bike to do testing with. one day we went to dinner and he
had decided quite emphatically that he wanted me to build him an electric
bike. he was sick of getting to work drenched in sweat or having to fight
for a taxi... and refuses to ride the bus here as it is damn near impossible
during rush hours... well since it was my first conversion i was a little
aprehinsive (sorry for my spelling) but was still confident and since we
have been friends for 3 years i was not afraid to use him as a guinnie
pig...
the first motor i ordered took 3 weeks to arrive then did not function well
at all ... plus they forgot to sent the nuts to mount the thing and they
turned out to be ASE threads !!! my god - what idiot uses ASE anymore ?
another week wasted and they sent the nuts but in the mean time i had gotten
fead up with them and ordered a complete kit from another factory - LiFePO4
battery and all. - well - -- i am very happy about that . the kit arrived
in less than a week then it took only several hours to complete the bike.
when my friend saw the bike he was really amazed and said " it looks like a
normal bike" . i asked what he expected and he said that he expected wires
everywhere and expected it to "look" like an electric bike .... this brings
me to another point that prompted his decition and that is the elelctric
bikes you can buy and that all the chinese drive look like outdated mopeds
or little motor scooters for women... we would not be caught dead riding
something like that.
my original objective was just to test the batteries, but now it seems i may
be in the e-bike conversion business as others have shown interest in this
project and are asking about it.
i posted it on the evalbum but i think it is not available to see yet. the
picture is the guy i built it for (not me!). he is not a big guy but i hate
to say - as big around as he is tall., i think a little over 200 lbs - and
he is so happy with the performance - yes it was definatly an ev-grin and he
cannot say enough good about it.
today i should receive the motor to convert my bike. that should prove a
little more of a challange since my bike has suspension and i cannot use the
custom rack from the factory. and - upon his request i had eleminated the
shifting mechanism from his bike and made it just one gear but i plan to
retain all the gear system on my bike.. i will definatly post how that goes.
..
thanks
Rick
