Good questions Shawn, thanks.
I'm looking for ok performance. I'm shooting to be able to make it to
work and back - 15 miles. I don't need to go over 45 MPH. I have a few
hills. I don't need startling acceleration.
The chassis without motor and tranny weighs 219 lbs. The GE Motor is 65
lbs, and I figure 200 lbs for batteries, so it will back up around
original weight (473 lbs with ICE). I hope to eventually change over to
Lithiums, but I want to start cheap to get some real data so I know what
I really need.
The controller is one piece I hope to retain on any future upgrades, so
maybe I should go with a 4844 or should I be looking at a 4855 or 4865?
Price is an object.
Good to hear good things about Alltrax. Curtis was no help in diagnosing
my 1204x problems.

Hi Steve, What do you think the finished weight on the bike is going to be
and what type of acceleration are you looking for?
If the bike is going to be over 500lbs plus rider, the 300A controller might
be a little small, but I definitely like the Alltrax line of controllers. I
have used several of them and they have all held up great.

Ok, I've officially started my BMW conversion. I'm going to start off
with an Elec-Trak snowblower motor and some AGMs to get a feel for what
I really need. I was hoping to use a Curtis 1204X controller I had
bought, but it doesn't seem to work. So, any suggestions on controllers?
I'll be running 36 or 48V. I guess the big question is what size
(amp-wise) a controller I need since that correlates with price. I'm
thinking about the Alltrax 4834 : 135A - 1hr, 300A - 2 min.
