What range and speed will I get with this kit?

[josaphine30]

Hi everyone. I just ordered the em3ev 500W DD Kit (http://em3ev.com/store/index.php?route=product/product&path=36&product_id=54) With these options: Motor speed: Rear 275RPM, Controller type: 9 FET 30Amp (37V-72V) and Wheel type: 26" Alex DM26 Disc. To go with this kit I ordered a 36V 20AH v2.5 Battery from Ping. Can someone please give me an idea of what range and speed I will get with this and also what range and speed I would get if I changed the 20AH Battery to a 15Ah.

Thanks

cell_man at EM3EV.com has listed the loaded RPM (under average conditions). 275-RPM is around 21-MPH, 34 k/h

Range depends on how many hills you have, how steep they are, and mostly by how much you pedal. As a general rule of thumb, I like to use 2 miles per Ah. So, I would say you'd get 40 miles from a 20-Ah pack. Others will get more or less miles per -Ah of battery size than me. If you never pedal, you will get fewer miles per -Ah.

I would guestimate 18-20MPH + or - a mile or two depending on tire pressure bike and rider weight ect. You can play with the ebikes.ca simulator and get near the same. http://www.ebikes.ca/simulator/ It will help with a range estimate as well.

Thanks for the reply.

Could you help with another question I have. I asked for advice the other day on which eBike kit and battery to get, I got good advice and decided to go with em3ev 500W and 36V 20Ah Ping Battery, everything has been ordered. Only thing now is I have mocked up the battery size from wood and it's very big and wont go where I thought it would on my bike. So I was wondering if 2 24V 10Ah Ping's would be the same power and range as the 36V 20Ah, the 24V batteries are smaller and I could put them in different locations on my bike.

The 24V packs will provide a 30% slower top-speed (13-MPH?). Also, they will have less power. two 36V / 10-Ah packs would give you the same speed and range as the single 36V / 20-Ah pack.

 

[dogman dan]

23 mph top speed, and 22 miles at that speed. Not a guess, but based on thousands of miles with a similar motor and the same battery.

Slowing down you get more, 30 miles is quite possible at 18 mph, and my personal best was 39 miles.

Re reading, I see you are getting the 30 amp controller. With that, you might get 1-2 mph more, and only about 20 miles. I was using a 6 fet 22 amps controller.

Hi Everyone, I have ordered the 500W Direct Drive eBike kit from em3ev, I got the 275RPM Motor, the DM24 26" wheel and the 9 fet 20A controller. To go with this kit I ordered the 36V 20Ah LiFePO4 Battery pack from ping, after I ordered it I mocked up the size of the battery out of wood to see if it would go on my bike okay but it is too big. I need to know what range can I expect to get with the 36V 20Ah LiFePO4 Battery pack and what range I would get if I downgraded to the 36V 15Ah LiFePO4 battery pack as it is smaller and would fit on my bike a lot easier. Thanks

Is this a joke? Didn't you already have MANY MANY answers from the other two threads?

Varies massively on hills and such. My 1300Wh battery can go anywhere between 10km and 200km. http://www.electricbikesimulator.com/

cell_man at EM3EV.com has listed the loaded RPM (under average conditions). 275-RPM is around 21-MPH, 34 k/h

Range depends on how many hills you have, how steep they are, and mostly by how much you pedal. As a general rule of thumb, I like to use 2 miles per Ah. So, I would say you'd get 40 miles from a 20-Ah pack. Others will get more or less miles per -Ah of battery size than me. If you never pedal, you will get fewer miles per -Ah.

When I ordered the motor Paul from em3ev emailed me and said it would only go around 16MPH.

but you have ordered everything already? did you ask ping to build the pack in two sections so you could mount it in the bike frame? there may be time to contact him if you just ordered it.

must be hot in texas today?

Yea I asked ping if he could do it in 2 parts and he sent me the dimensions but its still a little bit big, if I can I think I am going to change my order to the 15Ah instead of the 20Ah

 

[dnmun]

he can do that for you if you get to him before they build it. do you have his email address?

 

[josaphine30]

Yea I have it, thank you. I have asked him to make me the 15Ah in 2 parts, that will fit on my bike. Thanks everyone for the help.

Maybe I'm confused about the motor you are getting. I was under the impression that EM3 sold the 2807 winding, and gave speeds and distances for that in the other thread.

16 mph on 36v sounds like the slower 2810 winding, which happens to be my favorite, at 48v. It's a very nice motor, able to really stretch your distance by not making heat from your precious battery capacity. Faster motors may run hot, squandering your power.

At 16 mph, you should see about 30 miles from a 36v 15 ah pack. Maybe more depending on how you pedal. At about 15 mph pedaling becomes a lot more significant in your range. Pedaling briskly, you can get your draw down as low as 200w, stretching your distance greatly.

No matter on starting new threads, especially when others pick fights and your thread disappears so the moderators can discuss it in private.

 

[josaphine30]

I have changed my order with ping to the 36v 15Ah battery, he was very helpful and changed my order with no problems. Paul at em3ev said the 275RPM motor will go 16MPH, but I have been told here it will go 20MPH, can anyone clear this up for me? Thanks.

 

[MadRhino]

Both are probably right...
You can assume that it will do 20 Mph with a freshly charged battery, and 16 for most of its range.
Then, riding weight can affect top speed
