You're referring to the spindle freewheel mechanism, not the one-way bearing typically referred to as the "clutch" (just to avoid confusion for any other readers, replies)

Biktrix also sells these replacement parts, if you've bought an Ultra motor from us (for future reference).

Mobilith SHC 100: Synthetic base oils (Proprietary), Lithium Complex thickener (proprietary), Anti-wear, Extreme Pressure Applications: Electric motors, high bearing speeds, commercial aviation wheel bearings, automotive/industrial multi-purpose 150C Max operating temp. Mobil 28: PAO Synthetic base...

Interesting website, interesting wording... Interesting choice of components

coaxial..JPG Screen grab from website - Looks suspiciously like a cyclone coaxial motor to me? By reading some of the other posts you have made a bunch of upgrades to it? torque sensing for one? and a custom controller of some sort? Or am I off the mark entirely? Sharp eye, friend! We started with ...

I did not mean to come across as negative in any way. Hey not at all! I really appreciate your questions and feedback, it's been a really exciting past week here getting more community into the project. Launch site for the product went live last night at 2200 hrs, check er out! xd.biktrix.com Cheer...

Bullfrog, we're primarily looking to sell these motors on our own bikes, many of which are built on compatible frames. Selling motors for DIY is a bonus opportunity for adoption, which I'm expecting will lead to even more variety in applications

Just a suggestion, design and offer a separate motor that will mount similarly to the BBSHD as well as the one you have...that will should cover just about every bike frame made today. Unfortunately, not every bike frame will ever be compatible with this type of drive system. 157mm is the narrowest...

Bullfrog, The ESC (motor controller) will actually take 72V Nominal (~90VDC) and up to 90A, but we have never tested the system that high due to our preference for commercially-available battery packs. Most likely the motor will burn out at those power levels anyway :) 50A is about what our pack BMS...

Mid drive, up to 60V, 50A, over 300 Nm torque at the rear wheel, tougher than anything I've ever ridden. We have tried to destroy these bikes and nothing will break (besides some early electronics iterations, usually from R&D guys wiring things up weird, the engineers did nothing wrong!)

How can anything made in Canada be any good? Except road blocking?

Too much TV for you! Get back on the bike

Thanks, whoever, for moving this to For sale - New

Totally not what it was about.

last one was kinda shit, here... Four Days now, really:

Happy weekend! Cheers,

here ya go, teaser of a real motor!

Six days

These new IPM motors look like great quality, I'm interested in more information on the manufacturer/supplier?

Haven't forgotten about you guys! Public launch is slated for Feb 22, but I'll share details before then probably.

Hi, excuse me if I get in the way, but I would like to ask you a question, can I install this motor on a 190mm rear frame? Actually yes. I have one myself, fit fine, typical to use some spacers to get it just right. I'm running it with Grin Baserunner, peak wattage 1500W, in a commuter bike with to...

Alright folks, I've seen the first video and it is amazing... But this will have to be filed under "Best Mid Drive Motor 2022" as I don't think I can share till January most likely. I'm certain you're all going to enjoy this one!

Great build, lots of fine work in there! Bike looks fantastic too. You mentioned the cyclone planetary reduction, some of those are actually good! They really need the proper grease to work the way they should. Mobilith SHC 100 is perfect choice, about 1/3 of a whole tube. Assuming the gears fit wel...

Yet another promising project stalled with the woes of home hobbyist CNC... best of luck, I do think it's always smarter to outsource the CNC milling/laser/etc. Owning a finnicky CNC, at best, you'll break even (best case scenario!). Applying time and skills to design is more important, leave the cu...

No derailleur or IGH will perform well if you're not controlling power output during shifts, that is a fact. Even a Rohloff shifts like a piece of garbage if you don't cut power. My solution has been to manually interrupt power during the shift with an additional mini-lever, which uses the front ebr...

So a couple of weeks turn into a couple of months. Is it "soon" yet? I'll keep you guys posted here for news, we're making quick progress with the film work (marketing), and other things that need to be checked off before product reveal... It's been a very exciting couple of weeks for the...

Do the smart thing and outsource the cutting. You'd be done years ago, for less cost, with less headache. Your machine didn't fail because of bad luck, it was lack of experience (and cheap equipment). You can outsource the cutting to a professional jobbing shop with expensive, reliable tools, and th...

The mid drive requirement is not so easily dropped. With a semi recumbent bike, i have a very light front end, and could use a mid drive as ballast to prevent power wheelies. Ideal place to put a motor is up front, ideal traction wheel is in the back because >80% of the rider weight sits on the bac...

I guess 28 amps versus 30 isn't really a big deal. I'm just one of those types that doesn't like to leave any performance on the table. Right, and by the same logic, you'll be leaving reliability and uptime on the table by mucking with the stock controller. Best performance solution is to keep stoc...
