    Alltrax controller now in AC/PMAC/BLDC game?

    I didn't know they sold anything other than brushless controllers until now.

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    Well first off, it's an axial flux motor.. these are typically more efficient than the radial motors we run.. The end turn losses are probably extremely minimal and it's also likely they used the highest grade materials they could get their hands on at the time. Mass in in kg It's a balls...

    Are framework laptops any good?

    Wow, looks like you ruled out that idea, lol. Needs more refinement and better QC i think, i wouldn't tolerate getting devices that usually had some hardware issues. Back to dells i guess!

    Rules of the off topic section.

    Here's the problem. Otherwise good people get so heated in these discussions that they consistently ignore the rules even when i give them multiple warnings. If i was strict with these rules, i'd be ending up banning a lot of people who were just having a bad week or whatever. So instead we...

    Trump is against everyone having an electric car

    Sigh, it's election time and you guys can't resist but stray off into political land.. Please read this: Rules of the off topic section. Sorry but i need to punish the whole class and dumpster this thread; let's not have another go this way.

    That's the funny thing, we had enough disk space, it's just that one database table crossed the threshold of mysql being able to process it! But yes that is the bane of my existance and i'm determined to finish a disk space monitoring system by the end of the year.

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    My bad! Yeah the L10 wiring and connector are a big choke point. the rating of the phase pins is <90A. Wondering, do your cables get hot? I ran mine around 2kw for a while and noticed the motor barely got warm, impressive, so i think it could handle a lot.

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    I agree. CSIRO had a ~97% efficient hub built in 2011. The cost to produce it was $10k and everything back then was done by hand. Multiple motor factories wouldn't have to build said motor by hand, they have machines that can do it. The materials are no longer unobtanium either. You could mass...

    Lightweight carbon framed hub-motor build - Goal of 20 lbs or less

    Please don't buy a Chinese Carbon frame.. Carbon frames are already bad enough in that they fail suddenly without any indication by shattering. They're the structurally weakest of all bike frame types. And that goes for major makers who know what they're doing when building these things, use...

    Deleted some overly political ragebait, for those wondering about the discontinuity. Sorry Europeans and everyone else, i know you got your own crap to deal with!

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    AFAIK you won't find a motor this well built and efficient at this cost, anything at a lower price point ( sometimes even higher ) is going to lack there. I'm a big fan of the RH212 if you don't need all the power the leaf has, but, i'm thinking if you're in Australia, you may not like the...

    Designed a retention policy for that data and some others. Will implement that later. Should be a permafix for this problem.

    Morning. I'm awake and at the controls. Thanks for the report. I did get a ton of alerts in the morn too about slow performance. It appears that xenforo doesn't have a retention policy for it's mail logs, and they reached 128gb in size in the 1.5 years we've ran this system. Apparently a...

    Cheap build opinion

    Damn, you can still find a kit for $176? I paid that for my first geared kit back in 2011.

    Cheap build opinion

    Outlined above.. it's going to be inferior in every way to a brushless.

    Cheap build opinion

    These are brushed motors. They won't take pas because the controllers are never built for that feature. They're very heavy for their power output and not efficient. I suggest spending another $100 and getting a hub motor if this is your first time.

    Bikeon, "cassette drive" torque sensing motor

    Of course some 10lbs Chinese mid drives are gonna be less expensive than an American made, low quantity, bleeding edge product. I personally don't find those Chinese mid drives interesting at all. Different strokes for different folks, man. This would be a great motor for a flat area. The 4lbs...

    Ultimate puncture proof bike tires? testing Kenda K-shield and K-shield Plus

    Following up. I had the first goathead flat on 08/26/2024. It's goat head season again... just as the weather is getting good. Measures 4.5mm. They'll just get nastier from here on out. Got out the regulation grade poking device: Again for reference, here's the poke test measurement on...

    Action Camera

    Do you really need GPS and a display? That's an impressive unit for the dollar, i've never thought about buying dji before. If you are looking for inexpensive, consider a sony action cam.. they can be bought used for nothing and tend to be very reliable. Very good anti shake.

    How about buying components that have instruction manuals that explain these things?

    6 punctures in 16 months, help!

    Interesting, but only 780g of rubber Here's a good review: Maxxis Overdrive Excel Tyre | cycling-not-racing I believe Schwalbe has thicker tires available but the low rolling resistance of those is nice to be honest, schwalbe puncture proof tires have crappy ride quality and traction for me...
