BMC hub motor Ebike conversion kits from $400

[snowranger]

I'm test riding Ilia's 600 watt speed motor right now. No charts or graphs. With the Infineon 48V 30amp controller and Ping V2.5 48V20ah, I am getting a top speed around 29 mph with cruising wattage of 1000-1100 watts and peak bursts to 1300 watts.
By comparison, my 400 watt motor with the same set-up hits 27 mph with cruising watts of 900-1000 and peak to 1200 watts. The torque is similar.

I am liking this motor.

how well does the 600w speed motor handle 72V?

I posted my experience with the BMC 600W (Torque Version) at 84V just a few posts above. The 84V batteries I use have lots of sag tho so it should be comparable 72V.

Great price. What controller are you recommending with the 1000w? I hope everyone is aware that other BMC retailers are still experimenting to find a controller that functions with this new, untested motor: http://endless-sphere.com/forums/viewtopic.php?f=3&t=11205&start=0&hilit=bmc+testing

I can now attest that the Crystalyte Digital 48v48amp 18fet controller will run the BMC V3 "1000w" nicely. The big problem with the motor now seems to be the small wire size of the phase wires. They melted the sheathing on mine today.

This info is for the 600W TORQUE motor but it might still be similar and useful for the SPEED motor.

Dirtdad, E-Ticket, and I normally get together once a month to do an e-bike ride together (it's become our tradition), and so yesterday we all just finished a 40-mile ride together. So the nice long ride gave us a a good chance to try out our equipment and so we ran lots of experiments.

I run the 72V 48A 18fet Crystalyte digital controller with my 600W BMC (Torque) motor. This setup turned out to be "very torquey" (as Dirtdad put it) and it made hill climbing and accellerating a breeze. My 36V booster pack fried and so I reconfigured my main 48V 15A battery pack to 72V 10A pack. At 72V the motor was able to hit 34-35mph (speed motor should obviously hit higher speed). The motor felt warm but not hot and no signs of wires overheating. Controller had no problems with heat and was fairly cool to the touch the whole time. Cycle Analyst showed my max current at only 36A (so controller still had a lot more headroom before maxing out). I've got more work and more tests to run but for now I'm pretty happy with this motor-controller combination.

Ilia built a kit for me and it is very nice. He was extremely responsive to all my emails and painted the hub black to match my bike.

Finally got batteries to handle the controller amp draw. My DIY, patent Pending "Bosch Torpedo Fatpack". http://www.endless-sphere.com/forums/viewtopic.php?f=14&t=13037&p=193145#p193145

The basic Throttle is not as smooth as I would like....I will try to switch to a Magura I have if i can get the wiring right.

My rides have been totally fun and it eats up most of the hills in Ventura County. Easily gets to 25mph on the flats. Not very noisy at all.

I LOVE IT! Thanks Ilia.

You absolutely can't go wrong with ilia and his kits. I had some issues with mine and he was always quick with e-mails and educated me a lot in e-bikes and what to expect from this kit and how to make it last. I highly recommend buying from him. You won't be sorry.

I'd hate to see this thread scroll off so I'll give it a bump.

Will a front version of the V2-T be available? If so I might be interested. It's hilly where I live and I need to haul my BOB trailer. If so put me down for one in about a month or whenever I trash another gear(which I just replaced one today). It's time for me to upgrade. I'll only be running at 48v so...

[Canis Lupus]

I've bookmarked this thread. I'm interested.

Do you post internationally, to Greece? If not, how much would postage cost to Florida, my brother's address?

It's basically the same kit I was looking at putting together although I did want the option of eventually running a 72 volt combination sometimes. The controller provided would need to be upgraded for me to do this.

[nicobie]

I believe the controller that Ilia ships is a 72v one.

[TPA]

I purchased the controller and CA that Ilia sells. The controller is the 24-72v Crystalyte analog start immediate controller. He even calibrated the CA to the controller for me. Fabulous stuff!

Ilia has not posted since august, but I see he logged in today. He also puts the motors for sale on ebay at times.

One of these days, I plan on getting the entire kit from page 1. I hope he offers the kit again at that price, it's a steal.

[Guest]

Is this still available?

[Canis Lupus]

I believe the controller that Ilia ships is a 72v one.

So it is, even better. Thanks.

It is, I just bought one of the 72v35a analog xlyte controllers from Ilia, I am a repeat customer. I'd contact him directly.

^ Done. Thanks

Thanks for your comments everyone!

I sill have 600W kits with speed or torque motors (see 1st post).

Also available BMC 1000W motors for $495

[TPA]

Is that crystalyte digital controller working with the 1000w motor?

[jesuss]

hello can you send this to spain? how much is the shipping? thank you

Is that crystalyte digital controller working with the 1000w motor?

Just did a few road tests with BMC 1000W motor. Well, the results are not impressive. At 50V there is no difference in performance between Crystalyte 35A analog and 50A digital controllers, except that with digital, motor is jerky on take offs (between 0 and 3 mph), and with analog controller, take offs are very smooth. So I'm no longer offering Crystalyte digital controllers.

At full throttle, on take off motor consumes 15 amps, 10mph - 20amps, 15mph - 25amps, above 25mph 29-32amps.

Also, it seems 600w speed is slightly slower but has more torque than 1000w.

BMC claims that V3 motor goes 40mph with their new 50amp acontroller, I will have those controllers available around mid December. V3's are available for $495.

[ebikes-sf]

There was some delay in production of BMC 50A controllers, I should have them after January 10th.

[ebikes-sf]

To address questions from a few people about differences between different BMC motor models (to my best knowledge):

600 w torque (V2T)
Coils are made out of thinner wire and have more turns therefore motor has more torque at lower speeds but has lower top speed than V2S or V3. Top speed in 26 inch rim @ 50V 30A is about 24-26mph. Motor tends to heat more than V2S and V3 while climbing hills (at lower speeds).

600 w speed (V2S)
Coils are made out of thicker wire and have less turns than V2T - this is the only difference. Top speed in 26 inch rim @ 50V 30A is about 29-31mph.

1000W (V3)
Coils are made out of thicker wire and have less turns than V2S. Gear/clutch assembly mounting has improved from V2. Top speed in 26 inch rim @ 50V 30A is about 30-32mph. This motor is able to withdraw more current/energy (at higher speeds) than all other BMC motors. I have not yet tested it with new 48v 40A controller - i should be able to do so and post results around Jan 17th.

[dannyboyohyeah]

I see this is a rather old post. Wondering if this kit is still available???? It's exactly what I've wanted ...but I have one question...between the torque version and the speed version, would you say the speed version is still capable of climbing hills well? What are the top speeds (on the flat) for each of these for example, at 48v? Thanks

[The Mighty Volt]

Hi there

I own a 48v 20 AH duct-tape battery and a 36v 20Ah battery.

I am looking for a very torquey but also very reliable rear brushless hub with internal gearing.

I would be grateful to hear of any offers you have that suit my batteries

Is the original offer still available, and will it suit my battery packs?

Many thanks

PS do you ship to Ireland?

[ebikes-sf]

Yes, I have BMC 400W (V1) front. BMC 600W (V2) Torque or Speed rear, and V3 motors and kits available. I can ship worlwide. For your batteries I recommend a kit with BMC V2 speed or torque motor, I prefer speed motor - less torque at lower speed (still plenty to deal with hills) but higher top speed. The original offer still stands please see first page of this thread for details.
