Which motor and battery for touring rinding with some hills
Hi every one!, i have basic english so be indulgent .I read a lot of post so i feel i did a ggod job as a newby. There are a lot of questions both in the text and at the end. I like to understand the why of the answers so let yourself free and dont hesitate to correct info and add suggestions.
my weight including the trailer BOB with cargo will be 250 lbs maybe more total
i will use 26 inch wheels
i will go up some moderate hills and the motor need to be able to do most of the work without me having to worry about breaking matérial
i will pedal constantly with little force because my knee hurts but i will still help the motor
i want to be able to pedal without resistance (or very little ) when not using the motor
it would be good if there are replacement part for motor just in case
i intend to do long runs like 40 miles
speed is not so important for now but i would like to be able to improve speed with eventual additionnal battery.18mph seems sufficent for now
will want both throttle on demande and like 2 or 3 different level of pas
i need to choose battery and motor. The other component seem less critical.
for some reference points lets take 4 hill
A500m 11%
B 500m 18%
C 5% 7km
D 9% 7km
BATTERY.
I think building a pack from makita is a good idea. I hesitate on the following choices because i don t have the knowledge perfect enough to match them with the motor i have to choose(ATM i feel like the bmp cst would be a good choice(36 or 48 500w maybe at witch rpm (remember some hills)).
I can get approx 160 x US18650V cell(1.6Ah) nominal 3.7 v.. max discharge:?unknow?. What kind of riding would this translate in? Sufficuent?
Or
i can get approx 168 x 18650VTC4 (2.1Ah) nominal 3.7 v/Max. continuous discharge current: 30A :But they are more expensive. Not sure if i need those how would the concretly do a difference?
MOTOR
I need reliability, tork go up hills with my cargo without heat.i would like to choose one tha gives me possibility of future added battery .
Here is what i noted while reading several posts. :
Q 100cst
36 v 201 rpm have good comments but is said not to be enough for more than 200lbs.
Some install 2 x q100 one on each wheel but is this better than just 1 bmp for example? Is it efficient? With two it has same weight as bmp. One advantage is the possibility to remove one if i want lighter setup without cargo. Disadvantages I am all ears open?.
Q 128
not recommended since a couple of years in several post .
BMP bafang
-cheaper than mac, price ok, weight around 4 kilo . is said to have a lot more torq that q100
-comes in :
+350w 36v RPM :270 https://bmsbattery.com/motor/505-bafang-36v350w-cst-rear-driving-hub-motor-motor.html
+and 500w 36vrpm 270 https://bmsbattery.com/ebike-kit/492-bafang-36v500w-cst-rear-driving-hub-motor-ebike-kit.html
+and 500w 48v rmp 328 or 201 https://bmsbattery.com/ebike-kit/804-bafang-36v500w-cst-rear-driving-hub-motor-ebike-kit.html
-comes 328 rpm said to be only suitable for light rider 75 kilo and less wihtout hills.
- i think the orther choice is 201rpm
-Possibility cst for better cassette gear. Becaus bmp free wheel threads break of occasionnaly.
-Bafang are sait to be not smooth … what does it mean concretely? . Is said not to be quiet... how loud is it?[/b]
The motor in this wheel kit RPM :270 seem to be different??[/b] from and not same color as the 36v above. And are cheaper with wheel. Why? https://bmsbattery.com/ebike-kit/589-bafang-36v-cst-rear-driving-e-bike-motor-wheel-ebike-kit.html#/204-voltage_power-36v500w
There are « bpm2 wich offer mid 3 speed rpm
» 48v 500w rpm 201or 260 or328 https://bmsbattery.com/ebike-kit/586-bafang-bpm2-48v500w-rear-driving-e-bike-motor-wheel-ebike-kit.html only 134 dollar!! anyone knows if it has proven reliable? it is not cst... can come in a kit
Some say code 11 code12 are the best . why do they say this?
MXUS
I read they were discontinued.
It is said it need at leat 44v to climb a hill
MAC
is maybe overkill, i dont know , im a newby! Hahaha
EEZE
i don't know them.
Keeping in mind my cargo and some hills [b]what motor are your advising me and why?
2x q100? BMP? BPM 2?
what are the advantages disadvantages[/b] of chosing 350 or 500watt why?
What are the advantages ans disadvantages to choose a 36 vs vs 48v.
Could i run a 48 volt with 36 volt battere? Good idea? vice versa
would a 328 48v 500w climb hills easily? i read the 328 have better speed possibilité than 201 but no mention about hills....
What about the battery, 18650v or vtc4? Can 160x18650V do the job?
Why [b]should i consider investing more money to get vtc4?
