ebikes.ca Hub Motor Simulator

[marty]

I been thinking.... Forget this Electric Motor idea? I got a really nice bike that is designed to be pedaled. With a few years of training, healthy diet, and careful use of steroids, I could ride as fast as Lance Armstrong. Only Joking :lol:

Drunkskunk,
From what you type. Looks like bigger motor is better?

I been thinking.... Lets forget all these charts. I need to listen to what I read. I copy from "Justin" the guy who made the Hub Motor Simulator ebikes.ca/simulator.

I copy email from Justin:
Hi Marty, if you want to travel at 30 mph, then the 500 series motors
are a good bet. At 48V, the 5304 is pretty much perfect, and you
should find that your range with a 20Ah pack is about 30-40 miles. If
you went with a smaller and less expensive 400 series hub, then you
would want the 406 motor. You wouldn't have the same off the line
torque and power and hill climbing oomph, but the top speed would be
comparable.

With no motor bike is a 36 LB joy to carry up the stairs.
Here is estimated weight with motor.
Bike 24 lb
Front wheel 5 lb
Rear wheel with 5304 motor 25 lb
Battery 20 lb
Controller 3 lb
rack, odds and ends 3 lb
Total 80 LB load to carry up the stairs. Maybe I will be able to ride up the stairs? Going down stairs is no problem. Bump. Bump. Bump.

List of parts:
26 inch 5304 Rear Wheel (with disk brake I hope?) Thinking about only using one rear gear and eliminating the rear shifter?
72V 40A Start Immediate Controller
Crystalyte Half Twist Throttle
72V 40A Start Immediate Controller
Direct Plug-in Cycle Analyst
Battery I got.... details are:
48V 20Ah Li-ion
(13 cells)
max discharge current 60A (peak)

What do you people think?

If you have to carry the bike upstairs then definately get the "406" motor, which is the same one I'm choosing but I have a 20" front wheel.
The motor is 10 LBS lighter, couple hundred cheaper and only will need a little help up the steeper hills. I personally don't mind pedalling and think it is part of cycling, even ebikes. I would also choose "Lifebatt" cells and just get the 10ah to start, another weight savings.

Already have the battery and everything else being the same, only save 10 pounds with 406 motor. Not much diference between 70 LBS and 80 LBS?

My first Electric Bike Project was Bionx PL305 Chose that for light weight.

That Bionx company has a good product and NICE pictures on there web site!
Bionx is good if ya want to pedal. Hopefully Electric Bike Project # 2 will be good to get from one place to another real fast.

Drunkskunk,

Bigger is better, but in most cases, Bigger voltage is all you need.

if you use a higher winding count, and higher voltage, you get the same speed, but with a higher torque output and better efficancy.

Use Ebikes' simulater, compare your 406 @ 36 volts to a 408 @ 48 volts.
They have the same end point, but the 408 is just a little more efficent, and making higher torque upto the end point, meaning its actual riding top speed will be higher.

Justin doesn't list the 409, but the 4011 @ 66 volts is similar, and while he doesn't list the 4012 either, I know from experiance that the 4012 @ 74V has the same unloaded freewheel speed as a 408 @ 48 volts, but a higher actual efficancy and top speed when ridden.

I couldn't hang with a 5303 motor for speed up a volcano, but then I could go farther on the same size (and cost) battery, and at only 63 pounds, I can carry my bike.
