So, since I've gotten into ebikes many years back I've had 5 different ebikes, 1 being a cheap scooter and the rest being custom recumbents.
I currently have a custom bike built (build thread: https://endless-sphere.com/forums/viewtopic.php?f=6&t=97601)
I recently managed to shear the axle on my qs 205. The bike has had other issues and things I'd like to change so I plan on building another frame, but this time I'm going to do it from complete scratch and use aluminum and build a full canopy for all weather driving.
I'm having trouble deciding what motor I should use.
top speed 40km/h minimum
voltage: I have two custom 74v 25ah sanyo 18650 GA battery packs (x2)
controller: ASI 4000 (I have the software so I can program it for any motor)
target weight: less than 75kg
efficiency: 20wh/km or less
trike will have full suspension
note: I'm 6'3" and weight 250kg
Stats from previous builds:
current trike ~105kg, 30wh/km qs205 ~12.365KV with 74v 50ah Liion ASI4000,
kmx trike - Golden Motor Pie 5, 44v 10ah 12s lipo, total weight ~45kg 26" rim = 12wh/km, 45km/h, not enough torque for hills
Unbranded steel frame - Golden MotorPie 5, 48v LiFePO4 30ah, total weight 60kg, 25wh/km, 45km/h, not enough torque for hills
Found this trike on youtube many years back it's what has initial fueled my idea (https://youtu.be/9na1kFdU9gs
Youtube velo: Crystalyte 3548, 60v, 20AH LiFePO4, 40A infineon controller (states ~200km range with pedaling) speed = 60-65km
my goal is to find a motor and rim size that can provide good acceleration and torque for hills but the efficiency for long trips. I have a J1772 connector that I use for long trips and my goal is to a long distance camping trip at some point but I need a range of 150km minimum, my goal would be to hit 20wh/km and then add a trailer for flexible solar panels.
A few motor I'm looking at are:
Another qs205 but with a slower KV wind (5t = 9.03kv or 4t+ = 10.63kv)
DD45_STD from grin with statorade added (8.8kv)
M3540R from grin with statorade added (9.5kv)
MTC3080R_TA from grin with statorade added (9.9kv)
for the motor I'd likely use a 20 or 24" wheel with 2 ply moped tire, for the qs I'd likely stick with the 17" motorcycle tire and the Shinko SR241 Dual Sport Tire I have on the current qs205.
Thoughts on motor options would be greatly appreciated, I'd even consider a mid drive, but I'd have to assemble a drive train for that as I use both forward and reverse on my trike (and would use it even more so if it had a full canopy as you wouldn't be able to flintstones it)
