I have an old road Sentinel Whisper road bike that I positively love riding. I've done thousands of miles on the bike, jumped many curbs, and worn out the final gear on the rear cassette from speeding with traffic through Columbus in my early 20's. I'm not as good as I once was but I would like to bicycle more often. I face a four mile ride to both work and my final EE night classes with rather significant hills in between. I'd prefer to not end up drenched in sweat when I reach either location.
That said, I will also be doing a lot of flat land riding in my free time. I am not sure if I should look for a mid drive or hub motor. I would ask for the opinions and experience of those who have used both to help me decide what to do. My ideal power range is 250-350W.
Experience:
I have already built a ridiculous e-trike (RIP) and a silly fast 1500w 29er e-bike with a hub motor a lot of storage for roaming through the nearby woods. I have extensive electronic experience in competition car audio, SMD amplifier repair, and tube amplifier design and repair. I am a decent programmer as well. In short, I am not afraid to piece something together or modify something to save a few bucks.
The Problem:
#1: I am stuck using my spare Luna 52V 14s battery pack that fits neatly in my backpack. It maxes out at 58.8V on a full charge. As far as I can tell, this is my main restriction on set-ups available.
#2: I am stuck on using the stock size 27" (630mm) wheel so I do not need to change anything on the bike. It stops and handles great even with 20 lbs of groceries on my back.
Goals:
Minimize cost: I am working on my second degree, working, and have all the adult responsibilies - a house, a fiancee, two kids and one on the way.
Minimize weight: I want it to feel like a bike!
Minimize drag: My 29er is hard as heck to pedal and close to 100 lbs! I want this one to still feel and handle like a bicycle.
250W draw: I only need help on the hills. I do not really want or need any more than 10A draw.
Utilize PAS and hand controls if possible
Options:
Bafang/Cute hub motor:
-Pro's: Freewheeling capability to reduce drag, probably a top pick for me.
-Con's: I have not seen these paired with a 48V 250-350w controller but may have not looked hard enough.
GNG Gen 2:
-Pro's: 48V capable, reasonably low power, low center of gravity
-Con's: I have no knowledge or experience with regard to these kits
??? You tell me ???
