Yes, that's true. Made just the one exception since it is a unique product near to release. Copenhagen accomplished the necessary: a bidirectional hub motor for both motive power and regenerative braking. I'm hoping one of my students will buy one, so the rest of us in the workshop can see it in action.

I'm thinking about offering a 1-day ebike workshop at the college where I teach Carpentry. I'd love to collaborate. I'm just beginning to develop the course, however and won't be offering mine until spring of 2015.

I would recommend the Bafang BBS02 mid drive kit as a top-10. Its very easy to install and works wonderfully.

You can buy the (REAL 9C) that AMAZON.COM is selling for this guy and save $40.00. AMAZON is making good on his product but if you go to( ebay xtremfx) you can buy the rear (9c motor x 26in.) for $239.00 this includes free shipping and the same (9c front is $439.00) these are (9c-9x7 real thing not clones also the controller will handel 48 volts. I tried the controller at 48 volt just to see if it worked and it did.then I installed my lyen controller on it. BTW i bought 2 rears from him and quick shipping. hes good to deal with. :mrgreen: :mrgreen:

Yea, there should definitely be some mid-drives, but I don't know anything about them.

There have been reports of failures, both with newer kits and those with more mileage on them, but I still consider them to be a good kit, when used for appropriate application like a commuter for hilly terrain. - An "Off-Road" kit it is not. When they work, they are excellent. - I don't think we have a good handle on what percentage of these kits have problems. - Perhaps Paul or LeGrand can enlighten us on their return/warranty repair rates???

+1 for AFT mid drive
Oil filled metal gear gearbox, ceramic bearings, proven cyclone/headway motor, external programmable controller option, noise reduction covers, solid mounting, gear covers, heatsink, fits up to 83mm BB, acs freewheel, standard 104bcd gears, and the list goes on. Available from 200w to 1680w.
This is the only mid drive I would consider for myself or freely recommend to friends.

The question posed "Why Falco?" as the purported "best" in the list? Not to get too technical, its because Falco is using a 5-phase motor. Typically, eBike hub motors are either 2-phase (4 windings) or 3-phase brushless motors, which have proven highly reliable. There is a higher efficiency in torque delivery with the 5-phase motor, however.
Image
With regards to using brushless motors:
Brushless motors offer several advantages over brushed DC motors, including more torque per weight, more torque per watt (increased efficiency), increased reliability, reduced noise, longer lifetime (no brush and commutator erosion), elimination of ionizing sparks from the commutator, and overall reduction of electromagnetic interference (EMI). With no windings on the rotor, they are not subjected to centrifugal forces, and because the windings are supported by the housing, they can be cooled by conduction, requiring no airflow inside the motor for cooling. This in turn means that the motor's internals can be entirely enclosed and protected from dirt or other foreign matter.

Wanted to do a make in conjunction with the ebike@technocopia.org workshop, to demonstrate as well as to promote ebike culture in the home city. So I picked up this 1984 Ross Mt Whitney MTB off eBay, where the seller has added in new tires, cables, front fork so its all almost as new:
SleekNSexy.png

The specs on this bike are nice:

I especially like the Ishiwata double butted Cro-Moly frame, something you don't see any more. I have a long rant on the virtues of steel frames for eBikes in my Letters to my nephew thread. But Cro-Moly steel remains the best of all frame materials.

After looking at and considering this list, and pricing, etc. I'm going with a MAC from cell_man at em3ev. The 10-turn version for torque (hills). I've come to the conclusion that the eZee, BMC and MAC geared motors are all more or less equivalent, but MAC's are coming in at a better price. Then there's the controller question - I'm taking Drunkskunk's recommendation at Motor Controller, why not bigger? 12 Fet vs 18 Fet:
Drunkskunk wrote:With a MAC, you're going to be abusing the $#!% out of it with even a 12FET controller. They will rapidly turn to large boxes of melted junk at the power levels an 18FET can handle. A 9FET is all they need. Its a geared motor, not a direct drive. The won't take huge power levels.

... so the 9FET controller. And sticking with an A123 nanophosphate battery of my own make. I mean we're a makerspace, so need to make something for the fun and economy of it, huh?

Here's video of a MAC build that has an admirable battery rack, wire-hiding and lighting system I'd like to duplicate:

I didn't see Ebikekit mentioned here and I gotta say they are good choice for both small geared and 9C style hub motors. Kits assemble easily and everything works. We have the 9C clones on our trikes and one time when a wheel failed (spokes) they paid for my bike shop to rebuild. They now do their own wheel builds and my wife's complete kit has not had any problems in about 3 years. They are located in Pennsylvania. I would not hesitate to buy from them. Prices are average but they run a lot of sales at up to 20% off, a great deal.

What about Max at http://www.ebikedeal.com

He has pretty decent prices on Crystalytes. If you email him he can normally hook you up with other motors too.

OK, he carries Crystalytes, which can be had from http://www.ebikes.ca/shop/conversion-kits.html {GRIN}, our forum sponsor, so call it deference.

The eBike Conversion kit vendors listed all include battery options. The easiest path for most will be to choose a trusted vendor and purchase a full kit, that would include a battery. Apart from those listed, http://www.pingbattery.com is highly regarded here on the ES forum. Then there is A123, which is in a class by itself, and making a battery pack from their cells. There are many threads dealing with the technicalities of that, including my own.

Update: from the Trusted and Reliable companies list for batteries thread: also http://calibike.com

I got my '85 Ross Mt Whitney frame and its a beautiful sleek well built road machine. After much consideration, what I'm planning on putting on it:
http://em3ev.com/store/index.php?route=product/product&path=36&product_id=138
  • Upgrade EM3ev vers. Mac , 500/1000W Pick'n'Mix Kit
  • Controller Type Infineon 9 fet 30A (36-75V, IRFB4110)
  • Motor Speed 410rpm loaded @36V 6T Upgrade
  • Front/Rear Motor: Rear
  • Wheel Type 26" Alex DM24 CNC
  • Spoke Type Sapim Upgrade (Silver)
  • Throttle Type Thumb Throttle
  • Ebrakes HWBS Sensor
And as before, building my own battery pack. My preferred cell is still the A123 cells AMP20 prismatic cells, but expensive and need to economize. So shopping around and found this: a LiFePO4 20Ah 3.2V 64W 5C Aluminum Encased. Doing 2x 12S1P 36V for 40ah or 1.44kwh for $858 or $595 per kwh.

I'm happy to include other motors in the list, but would do so only the basis of ES-forum repute, as in reported good experience, both motor & vendor, as with the others. Not, however, doing the research any more, so please post threads on the motor here. Preferably build threads. DISCLAIMER: I'm not a motor expert and am in no position to verify any listing. I'm merely one ES-forum member who did extensive research and listed these kits on the basis of the informed opinion of many others.
