"Edge" 1500W DD hub with 35mm wide stator, thin laminations, aluminum core

[calfee20]

Well I just ordered that big triangle. I got a rent check I didn't think I would see this year. I haven't had a financial planner in more than 35 years. I still have to try to keep myself in check though. That hub I was talking about would cost $1000 with a cycle analyst and the wheel build I want to try. Then a second BBSHD so I have a complete second bike. There is another frame I have been thinking of not to mention the trike I want to try.

Yeah I am keeping myself in check.

That's great news Bill, glad you are now happy with your setup. I'm still cruisin around at 30mph on the flats waiting for this 1000 watt to bite it so maybe I can get a bigger one, ( justification to the financial consultant in this house lol), just hate that the hills here are so hard on it. But I still use it everyday I get to work, as long as it isn'r raining. Had an idiot in a car ride behind me today for like a mile, he could have passed at any time, suddenly starts layning on his horn, passes and nearly cuts me off. I was doing 32, speed limit is 40. Some people just don't get it . At least he didn't hit me..... Ride on safely man, later

How did the test turn out Bill? Got me wondering if the comfort angle is the better way to go. Keep us posted man!!

Greetings Dale the new bike worked out great much better with a upright seating position
more like a dualsport in stead of a sportbike set up
the combo is still kick kin ass runs great no issues
it is great transportation I use it almost every day to get around on
cheers Bill

C20 got to thinking about the comfort thing and my other Gary Fisher Wahoo with the 800w DD 36v always more comfortable than my
GF genesis so you guessed it I changed everything over put the EDGE set up on that bike
much better different geometry higher steering stem more of a up right seating I think I might have it
did a test ride and it felt great

Thanks for the positive feedback! It is flat where I live, so I am only using two gears on my mid drive. The MXUS 3000W is a wonderful motor, but...it only allows a one-speed freewheel. It is also capable much more power than I would use, so it would be heavier than I would need.

I was very intrigued by the Leafbike 1500W, which fits standard 135mm rear dropouts, meaning just about any bicycle frame you like. It allowed a 6-speed freewheel so it "looks normal", and it has the efficient thin laminations, along with thicker factory phase wires. However, I never pulled the trigger because it did not have the aluminum core to manage the heat, effectively doubling the peak amps on flat ground, while being cheaper and lighter than the MXUS 3000.

I bugged a couple factories to make this, and finally someone took all the good features above, and added the aluminum core, so I bought one of the first units. I still don't know who is making these, but soon others will follow.

I don't even get mine hot yet (I am waiting for a bigger controller, am now using sensorless 12-FET), and I already added ferrofluid, so I could write about that, and get pictures for the article.

My first real bike after my teens was a Cannondale 12spd racer. Low bars and a skinny seat was fine when you are 20. It didn't take long to get old. Then a Specialized with a gel seat and more upright ride. It wasn't enough, it still hurt my thumbs and neck. Now my cruiser is totally upright with a bigger softer seat but I still need to tweak the handlebars. I find myself gripping the very end so I need at least a hand span more. There is always something.

C20 I am totally convinced that the bike will do 50 miles with out really peddling
the 14 mph spot seems to be where the motor is just starting to become efficient and that is barely 1/4 throttls
and using 100w I know that the electric motors are most effecent
when spenning fast but if I run it in that range I am toping 30 mph I don't want to really go that fast
but I don't know If I want to beat my self up that much and with as many stops I would have to make
it would take all day which I don't mind
I think I need to work on comfort control I need to get the handle bars up higher so I am in less of a sport bike crouch and more of a
dirt bike straight up position and work on the seat a little then 50 miles might be easier
Cheers

Update : 41617
Another run today rode it to visit my mom in the nursing home she got a kick out of it
Sorry no pix today of the CA read out to tired to get the camera out you will have to trust me
Started out with 58.6v
ended with 54.2
used 4.4 volts
traveled 30.964 miles
16.2 wh/m
max amps 50.43 the CA has it limited to 50 amps I might kick it up to 60 amps
and see what happens my wh mileage will probably go up
the sweet spot seems to be 14 mph taking 100 w of power to maintain that speed on flat ground
max speed 28.1
avg speed 13.1
a lot of hills and a lot of flats
I was pretty tired today so it was about 98% motor
I don't if I will make the 50 mile thing at this point 30 miles about wears me out
Cheers ole Billy

I read somewhere that below 12 mph or so there is no appreciable air resistance. That would explain your 14 mph sweet spot. I always assumed a BBSHD would be more efficient than a DD hub but you guys have me wondering.

This thread really has me going about adding a DD hub to my mid drive build. At first I thought I would need a steel frame to do the best job, like a Surley Pugsley. Then the other day while riding around town I had such a brain storm I figured out how to do it on my Electra Fat Cruiser. I was so distracted I had gone a couple of miles past where I had intended. This will have to be a mid to end of summer thing.

50 miles all at one go would be a bit much for me also. My 11 amp slimline will give me a reliable 25 mile range. For me to do 50 miles I would need, besides a larger battery, To go 25 miles one-way and then take a couple of hour break and head back..............calfee.

Dudes happy 4/20 day we should dedicate this day to the Mighty Spinning Magnets so it may go down in history
of our gratitude for him turning us all on to the mighty

I found some more information on that TDCM IGH. It has the thinner laminations.





I also found a new toy. It is an ebike simulator that will calculate power ,speed weight and range scenarios for bike builds. They have a nice database of hub motors, no mid drives though. They don't have the Edge hub in their DB but they do have the 35mm Leaf. Play around with the throttle settings to get desired speeds and you can really see how that effects the range. http://www.ebikes.ca/tools/simulator.html

Yep! ebikes.ca has a LOT of good info, Justin Le is a great guy, he is the inventor of the Cycle Analyst (CA) that you see so many of us using, it's a very handy tool, I admit though, I wish there was something with some of the features it has with out all of the extra stuff I will never use, it's designed to work with just about anything you can imagine, lets you adjust variable regen on a hub motor, limit amps & volts (the features I use most!) and a number of other things.

In that quote about that motor, the reason they are saying it's good for a 20" wheel recumbent, is because having such small wheels limits you in your pedaling gear range, and that motor + IGH allows you to have both in a small package, very nice design, just as it's been said, the motor is a direct drive, and the 9c although a decent motor, it's not the most efficient out there, and the typical electrical connectors aren't the best, I MUCH prefer things like the water resistant connectors you see used on Bafang products, that is quite a nice change from the typical JST and similar bulky connectors used in the average Ebike kit that are very open to allow water and road grime in.

These connectors are some of the best I have ever seen on a Ebike kit: (just using this throttle extender cable as an example, it's the connection that I SOOO much prefer to the cheap style in the pic below that is still used on many good Ebike kits, just a small thing that should have been up-graded long ago, I ride in ALL kinds of weather including Ice on occasion, so weather proof is really important to me.)

https://lunacycle.com/bafang-throttle-extension-cable/

This pic is of the older style JST type connectors and others that have the back-side open to the elements for the most part, not the end of the world, but most of these have to be packed with dielectric grease (back and front!) and of course, using DE grease is just a good idea in general, but the connectors used with Bafang products are just soooo much better for keeping road junk & water from getting inside.)

Man I need that whole battery/motor setup so bad it hurts. As per usual GW killer documentation. Dealing with a whole different " elephant in the room " at present time so I gotta make do with what cards I've been dealt. Best way to eat an elephant is one bite at a time lol. ( Even if the bites taste like crap). Happy motoring folks, ride on safely!!

Dale H you hang in there buddy

C20 I looked into this motor and it looks like the gears are for peddling and the motor does not use them
that would have been sweet if it did
the power out put cant match the edge but it is a nice set up and you don't need a derailer
