As an aside for the next person who comes along and reads this: There are 2-to-3-pin adapter cables widely available as this is a fairly common issue. Typically very short extensions. https://classic-cycle.com/All/3747/HIGO/Julet-adapter-cable-19-5-cm-for-ebike-2-PIN-red-to-3-PIN-yellow You...

You folks who are changing out crap cabling for quality cables should also invest in replacement cable housing. There is a huge difference in cheapo vs. 'compressionless' housing (the better Jagwire stuff meets this standard). The difference is felt in the cable pull. Compressionless housing...

Me three. I installed a gear sensor on one bike in 2018, and never installed another one. I do a stutter-step in my cadence when shifting and now, even on the bike with the sensor, that quick cadence interruption is automatic to my lizard brain. No need at all for a sensor. MT5e brake levers...

And this, plus the much faster closing rate of a motor vehicle vs. any bicycle - is why turn signals on a bicycle or ebike tend to be worthless. I tried them on the ends of my handlebars to solve the separation problem. The product is called Wing Lights and they seemed like a good idea...

Yeah its not like someone is going to dock their pay or not re-elect them. By consequences I mean some hurried backpedaling, some embarrassing temporary press and a new bill designed to band-aid the old one. I did some looking around after my last post in this thread and there is almost no...

Looking at it again, that does look like a big chainring to expect to be able to climb hills with. The specs say its only a Samox 44T which should be 104 BCD. If the bike will tolerate it, a 40T and a few less chain links could be a good start. Rear cluster is a steel HG400 11-36 9s which is...

It wasn't originally. As @BlackHand noted above, the bill changed over time to become something completely different than it was originally intended to be. When that hard 750w limit was introduced, it did garner some industry press which was where I first heard about it. There is no room for...

Yes. As has been noted above, this bill originally was all about mandating ebike battery safety. It got rewritten and added-to later on to become the monster that it now is. The industry and bike-lobby support it got was back when it was a battery safety bill. No stats. But I am very...

Bikes like these that come from a closed, proprietary ecosystem generally have barriers to doing something like changing their gearing. Bosch systems for instance. Bosch-allowed changes have to one of a few approved factory chainrings with only a couple of sizes available. The system then has...

It also completely obliterates the progressive agenda goal of weaning people off cars wherever possible and onto cleaner energy. In one fell swoop it renders bikes non-viable means of alternative transportation. One more reason I see this bill getting vetoed.

Yes but you will have to google for it. The CA government has a web site that lists all pending legislation routinely. It is not going to provide Cliff's Notes though. You will have to dig thru it or just become generally aware of the legislative climate by staying current with industry...

It would literally re-class almost every ebike in the state 'not an ebike' so I expect a veto. And if not, with literally millions of lawfully purchased ebikes now suddenly no longer legal, I expect swift consequences to legislators, not consumers.

SB 1271 will immediately render ALL ebikes manufactured to date under the current USA standards as unlawful and 'not electric bicycles'. Read the text of the law not the news articles. It contains a provision that puts a hard limit of 750w of output on all ebikes. 750w total period. No...

Battery quality at the low end you are describing is iffy at best (I would characterize them as 'garbage', and you can find examples where someone took one apart and found a button cell and sand added for ballast to the otherwise empty 18650 case). On the other end of the spectrum are packs...

Thats a big deal for me. I leave my bikes parked outside of stores, and it was a huge deal for me when I started building the batteries under my cargo floors so they could be just left on the bike, and even if someone knows the pack is there - which is never - there's nothing they can do about...

You know what would be really neat on this? Something that might be a lot easier than the norm thanks to the high level of electronics sophistication you are working with: Build in what is now commonly called a battery blender to parallel two packs. I feel unclean just writing 'battery...

So, I have an orange bike, and a green bike. And a black one. You can see where this is going. Maybe look into a snap-on cosmetic cover at that spot rather than a permanent molded-in (or whatever) choice. That would let you do covers for a variety bigger than just these three. Failing that...

Once that battery is gone, its probably gone forever. This is the reason I am staying completely away from any bike with a slick in-built proprietary battery. When the battery goes the bike is junk. Probably not even sellable. We already see this happening with ebikes whose manufacturers have...

I suspect what is happening is they are revising the product line. Probably to 48v. 36v has been dying off for some time as it is. The Yamaha bikes are tailored to the EU market and underpowered by North American standards. My money is on Yamaha either creating a new North American line...

Guessing the OP has long since completed his build. In case someone comes along later with the same question: This goes into a lot of drivetrain selection stuff. Lots about steel parts that are survivable long term for instance...
