I got my kit today it is a 48 V 1000 watt kit this is the link to the kit I bought
if you can not click it copy and paste to your browser if im not allowed to post links here im sorry

my question is this my control box has a plug for a PAS system 3 wires red green black
but the kit did not come with the parts for the pedels can I bypass this ????
do I have to buy a PAS system I see them on ebay I would rather not have a PAS system
if I can bypass this will someone please tell me how ??

thanks in advance for the help you guys rock

Don't have the same kit, but I think yours comes with PAS and cruise control capabilities. On my kit, which had PAS with all the needed components, I left it off and just "tied up" that wire(s). If I were you, I would get a torque arm for that motor (I have one for a front 350w, 36V motor.

datonamanmike

so your saying I can just leave it with nothing connected to it and it will be ok ????
tie it out of the way ?
I don't know what a torque arm is

See Torque Arms on Hub Motor Bikes | ELECTRICBIKE.COM.

Also Google will get you lots of other info and suppliers.

After reading up on the torque arms I did order one for my bike

chas58

Yes

datonamanmike

thank you chas

Ok got my bike up and running and im loving it My bike is 48 volts 1000 watts 26" front wheel kit
My batteries are 4 12 volt 9Ah wired in series weight of the batteries is just under 22 pounds
on my test rides im getting a steady 47 kph that is 29.2 mph
I got my torque arm today and my question is should I put the arm on the front of the forks or the back ????
Iv looked at dozens of pictures and it seem people put them on the front and rear .
so im looking for opinions

dilkes

Some correspondence I had with Justin at ebikes.ca on the same subject..hope this helps.

Hi Fred, yes that is correct.

Hello
I am looking at buying one of your new versions of the Torque Arms. I currently have one of the older versions. However, I have a question about the proper way to install on the front wheel.

Should it be installed on the fork so the arm part itself faces towards the front of the bike or so it faces towards the rear. When I look at your instructions, I think it says to install it so the arm part itself is towards the rear of the bike? Am I interpreting this correctly?

I drew a little sketch to clarify my question (I hope!)


Thanks for any help.

datonamanmike

Thank you dilkes I also have one other question.
My batteries are 48 volt 4 - 12 volt 9Ah wired in series.
Now is there a formula to tell how far ill be able to go on a charge ??
Or an educated guess Thanks again

2old

ebikesca has a simulator which should assist you. Of course, it depends on weight, wind, slope and a myriad of other factors.

datonamanmike

ebikesca is realy no help because my motor is not listed. so I'm asking again does anyone have an educated
guess on how far a full charge will last on my bike?? just a ballpark guess .

also I noticed that after 10 or 15 mins riding my positive wire on my battery gets hot
now this wire is a little smaller then the wire I used to connect them in series I used 12 Ga. but the pos with the fuse is
smaller and seems to get hot should I use bigger wire??

chas58

Yes.

Heat is bad.

Find a motor with similar specifications as yours (no load speed for example) and configure the battery & controler to match yours, and you can get a good estimate. Without that info, no one can estimate. I don't see much detailed specs on the ebay page.

But, the best answer is to ride it until it dies. That is what I do. I went 24 miles (36v10ah 15amps, 24mph). So I know I am safe for 20 miles, no worries. 24 miles is fine too, I just will be pedaling if I go farther.

SLA batteries tend to have a short life span, so keep that in mind.

Gyro

You have to figure out the total Amp hours for all the batteries you have. Then divide the amp rating for the device. Simple look. I have a 105 amp hour deep cycle backup sump pump running a 2 amp pump. I should get 52.5 hours of continuous operation before the battery is dead. If in my use, I let it run all the way down I'd kill that battery so I'd stop around 50% for recharged, 26 hours of continuous use.

In your use coming up the numbers may be problematic due to the varying amp draw of your motor. There should be some info on how many max amps it will draw at full output with it? That would give you length of time at max power output the shorties amount of time.


Look around this site good info there.BatteryStuff | Knowledge Base

chas58

Sounds good, but

I have 10ah battery, a 15amp controller and ride around constantly at full throttle. I can ride for an hour. By your thoughts I should run out of juice at 40 minutes. Obviously my average current draw must be 10amps (or my battery is bigger than labled). Not sure how anyone would know that without directly measuring current useage.

Gyro

Your motor should have a max amp rating listed some where in the instructions. Like the 2 amps my pump uses. An hour ride time would equal a 10 amp motor? 10ah battery / 10 amp motor = 1 hour. I have no idea what the controller would use. I'd guess at half throttle it would use 5 amps = 2 hours? Of course a bike usage would be a bit more complicated than a simple sump pump.

datonamanmike

ok here is what in going to do: I live in central Florida its mostly flat land but a little bit
of rolling countryside. I live near a long straight highway #40 east and west . It has A bike lane.
so Ill have a friend take off east for 10 miles according to the odometer on her car. At 10 miles
she will wait for me. assuming I make it to her we will head back west then if I make it home
I will have traveled 20 miles. that will FOR SURE give me an idea on how far I can go
if I don't make it home ill have her come get me and keep track of how many miles im short
we will be able to keep in contact with cell phones

chas58

Good plan.

FYI, I have lifepo4 batteries that pretty much maintain constant voltage and thus a “fuel gauge” doesn’t work on them. I have a range of 24 miles. Once after 23 miles I checked the “fuel gauge” and it said 80% full. A mile later it was empty. So, in flat lands, running it until it is empty is (for lifepo4) the best way to know. My bike pedals fine without electricity, so I can hit this limit many times and still get home fine (albeit a little slower in the last couple of miles).

In my case, I would ride 20 miles, and just do circles within ½ a mile of my home to find the true range (before I knew what it was).

chas58

gyro, yeah it is not that simple. You have no way of knowing the current draw unless you put a current meter on there (or unless you run the battery dry as above and calculate it). My motor, battery, or controller specs don't tell me the current draw.
