    [USA] Will Tariffs come about and lead to higher priced ebike parts

    From what I've heard aliexpress choice items have the customs fees included which can you tell because they are more expensive than they used to be. I placed an order awhile ago and seems to be through customs fine so we'll see.

    Electric Dirt Bike

    When factoring the speed you just need 3 things in this case, the motor KV (62), the voltage, and some idea of the motor's operating speed based on it's design and controller. For more basic brushless motors with no field weakening it would be voltage times KV is the motor's freespeed so that's...

    Bonnell 775 6000 watts

    So more or less I agree but it's a matter of degrees (pun intended), I want my bike to be slacker than a touring bike but to a point and I think some modern bikes are past that point. They would be too extreme for the terrain I ride which is often very tight and technical and at low speed. Wish...

    Lithium Titanite battery source?

    I've seen cells like 27.6v 40ah 1104Wh LTO Toshiba SCiB 20,000 cycles! 24x 20ah Cells which bulky for sure but should be of good quality and easier to assemble than lots of cylindrical cells.

    Bonnell 775 6000 watts

    I don't exactly get what the problem with the geometry is, it's mountain bike geometry with the presumed function you'll ride it on mountain bike terrain. Yeah it's less than ideal on the road, so is a road bike on a DH track. But I am curious Chalo what specific parts of the geometry you would...

    I can't tell

    Honestly I think I mostly wealth inequality, the internet, modern media and modern culture. And I don't think those are necessarily down to things like division, people have been strongly divided since we were apes but I think there are some particular wedges that politicians have figured out...

    No politics rule v2 - would it work?

    Yeah I was trying to think of what rules would make sense and I had some but it's hard. Some are easy and probably overlap with general rules, no personal attacks or general insults to any group in general. I feel like insulting politicians is impossible to stop, they just make it too easy...

    No politics rule v2 - would it work?

    Yeah I think moving into a off-topic and only banning those who go too far is ideal. Honestly I think constructive talking about politics by reasonable individuals who are debating in good faith is a good thing, honestly more of that would prevent the extreme side taking and echo chamber...

    Spintend vesc controller

    I use MG chemicals silicone modified conformal coating, the stuff in the bottle with brush is easier to use than the spray and you can use a UV light to see if you missed anywhere. You can program and update the firmware over bluetooth with the phone app but the desktop app is nicer to use and...

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    I think in the context of a any moderately sized or large hub motor I want it clamped down real solidly regardless if I use regen or not (I do for 95% of my braking). But like I just threw whatever torque on there and eh it's good enough if I don't use regen doesn't sound great to me considering...

    Spintend vesc controller

    The way I normally waterproof VESCs like this is by first open the case and conformal coat everything then when reassembling the case I silicone the two halves together and around the power wires. Then I 3D print a cover with a gasket that seals the whole top and has space for all my wire...

    Vesc and flipsky for e-bikes

    Any VESC can work with a bluetooth module, some have it built in. Honestly though I would buy a spintend or a MakerX which are only very slightly more expensive and much better made. As many have experienced the flipsky VESCs do work but not always well so can be down to luck if you just plug...

    best method to splice power wires when messing with battery discharge connector.

    I mean kinda depends on various factors, how much current are we talking, how big are the wires, how waterproof does it need to be. The best way and honestly it's pretty easy once you do it a few times is a quality butt crimp connector that is well crimped. And those depend on how much current...

    Mid drive chain efficiency and longevity tips

    I just reuse them, never had one break. I think quick links are made much like chains, any name brand will be built to the industry standard which I guess for chains is 8000N which is kinda weird because you look at tests and you expect super heavy chains to be way stronger and they end up being...

    Mid drive chain efficiency and longevity tips

    Go to goodwill or a thrift store and find a baby crockpot, see them all the time, no idea what they are for, maybe sauce of some sort? You can just leave the wax in it.

    Mid drive chain efficiency and longevity tips

    Eh whatever, you are free to ignore the evidence all you want, I'm more interested in the tribology science of why it does work. This is not some new idea that is only based on theory, there have been many well executed empirical tests done over many years. But hey just becauce you've just heard...

    Mid drive chain efficiency and longevity tips

    I mean Zero Friction's testing is the most rigorous and unbiased I've seen, the shear strength seems to be just fine and really the wax in part acts as a carrier for the additives that do much of the work by actually getting trapped between the metal surfaces but the wax does a better job of...

    Mid drive chain efficiency and longevity tips

    I mean I think the real takeaway from zero friction's testing is wax dip lubes obliterate drip lubes no matter how fancy. Honestly I have no need for real chain longevity (total ride miles is low) or efficiency (never have range concerns) or any of that but I will never go back to drip lubes...

    Direct drive hub motor for 1/10 car - outrunner with sensors? FOC? Needs reliable start from stop.

    I've seen a few very small VESCs but they are still rather expensive but they would allow you to use HFI or even encoders, both of which should perform better than Halls and much better than sensorless. I'm guessing the crawling ESCs you've seen run AM32 which has FOC if I recall, at higher...

    CYC X1 Pro Gen 4. Removing Hub drive from rim. Is this Quando Hub/axle combo strong enough?

    I think potentially the most important factor is how strong is the freehub, that is what has to take all of that torque. The final torque will depend on gearing. But the style of freehub, ratchet vs pawl, ratchets are generally stronger. Also fewer points of engagement is generally stronger but...

    Maxxis Hookworm still best eBike tire?

    I got a set of Hookworms, have yet to fit them yet, might just wear out the old DH tires that are on it now first. I went with them mostly for the wider 2.5 option although I was aiming to get a set of Schwalbe pick-up 2.6s but those are basically impossible to get in the US it seems. There is...

    100v speeds way off vesc

    Yeah if the motor doesn't have a high enough Kv it just won't go any faster without more voltage or a larger wheel. I mean field weakening will do a little but hub motors don't gain massively from that (and that's really asking to nuke that controller), over modulation may also give you slightly...

    [USA] Will Tariffs come about and lead to higher priced ebike parts

    Yeah I would do the same, but for what I'm looking for I don't think we are there yet. Even a mild recession though could see prices fall as people cut back, similarly China is hurting and it seems the only strategy they are willing to play is the same one they always do, keep dumping money in...

    20s Lipo for cyc x1 - external BMS?

    One of my bikes has exactly that, 5x 4S 8ah lipo packs currently with no BMS and using the controller voltage limit. Honestly if they are new packs and you test them to make sure their capacity is all in spec and charge them with a balancing charger and have a suitable fuse, it's fine (not ideal...

    [USA] Will Tariffs come about and lead to higher priced ebike parts

    I mean I'm buying food still but like this hyper consumerism system we live in can be a delicate balance. I love buying stuff just like most Americans but if you introduce too much uncertainty about the future, increase recession risks, and generally dramatically increase my taxes that balance...
