Hey, I've been reading around these forums for the last couples weeks and just joined.
I am about to build my first electric bike, and I have acquired most of the details that I need and would like.
The goal:
To set up a bike that can help take me up a large hill to school and back, which is <=2mi each way, as well as ride along flat at >=25mph.
Situation:
I am not sure of the grade of the hill and it varies a lot. Riding manually; at points I am in my lowest gear, and going an estimated 3-5mph. I am quite fit, and can make the whole hill, but it is a challenge each time. The hill has a peak at about 1.5mi in and dives down towards my school.
I also will be riding flat ground a lot, as I live in a valley. I would like to go at least 25mph on flat, and get a good 30-40mi distance if possible.
Bike:
I am going to be putting it on my 700c Diamondback overdrive mountain bike until I buy a frame that I will dedicate to being electric.
Kit that I am looking at:
MAC Upgraded from EM3ev - 8T or 10T (Some help on this decision would be great) --- I understand that the 8T will give me more top speed and the 10T will give me more torque.
50V Triangle battery Li NMC - 18.5aH - http://em3ev.com/store/index.php?route=product/product&product_id=123
Controller - ??? --- I am not sure if the 6FET would cut it. Should I being using the 9FET instead? Which version would I want, the one which works up to 52V, or 72V?
Charger - Will it suffice? - http://em3ev.com/store/index.php?route=product/product&product_id=120
BMS - Would this one suffice? - http://em3ev.com/store/index.php?route=product/product&product_id=75
Any input from experience or general knowledge would be wonderful, especially regarding the controller.
With torrents of gratitude,
Joaq
