Not to take away any of that study's conclusions (haven't read it yet) but I notice it was published in 2019, meaning the data was gathered prior to that. Given how fast this market is moving, that ebike world doesn't really resemble the one we live in now. On my current daily driver, which I...

You have to scroll back a bit and see that I was responding to someone who mistakenly asserted the speed was "virtually impossible to achieve" which I know to be wrong because I have done it versus just talking about it. And I wasn't the 'world class pro' he qualified his internet-smart-only...

Try out that attitude with the car driving public and see how far it goes. If someone is using a car (or a bike) for routine transportation, time to complete the task (of which the ride is just a means to and end and not an end in itself) and convenience are crucial. If you are merely engaging...

Specialized ebikes that are 250w rated have been dyno'd to exceed 750w total output (One test by a Specialized owner for a Luna Cycles Youtube event comes to mind). Reportedly Specialized threatened to sue the company that posted the dyno run. This was many years ago so I seriously doubt they...

If you followed the bill as it went from its initial proposal to its final form, you would have seen it morph from a pretty straightforward battery safety bill to the plate of spaghetti we have now. IIRC the hard 750w limit showed up only a month or two before it went to its final vote. I...

Looks like Electrek decided to give this 750w issue its own dedicated article, that just came out. https://electrek.co/2025/01/02/new-california-law-makes-crystal-clear-which-electric-bikes-are-now-illegal/ They are citing exactly the provisions I am above. The specific bit on the 750w hard...

Nor did they bother asking the advice of one. Or even someone on this forum. The whole v * a = w thing is a foreign concept. As is what it takes a mother with a small child to pedal up a hill with a couple bags of groceries (my neighbor fits this exact description and rides a Globe Haul ST)...

Of course it should. What if a child is molested by a parent? Or physically abused? Or emotionally abused? What if the parent abandoned the child and remaining parent for most of their lives? I have known people over the years who have fit into all of these categories. In some cases the...

Yeah my power limits are there to allow me to carry things, and not drive my car. I carried three bags of gravel back from Home Depot over the weekend. I believe that was 165 lbs of cargo. I didn't exceed 10 mph and I climbed grades that were as steep as 16%. Thats a car trip if you own a...

I know what you said in the thread, but you missed 312.5(d)(1). You were looking only at the preamble, the opener to 312.5 and 312.5(d)(2). 312.5(d)(1) stands entirely on its own as an independent restriction, and is new to the vehicle code. It complements 312.5(d)(2) and between the both of...

As a California commuter, I have been paced many times by squad cars, and radar'd by stationary traffic cops as well. My typical cruising speed on my commuter was 30-34 mph, and I achieved that with a bike I geared myself with a big chainring and a small rear cluster. I've been paced at 34 for...

It doesn't say that. You have to read the text of the bill rather than just the preamble which states this simpler version of the regulation, which is what Jeremy cited in that thread: "This bill would clarify that an electric bicycle is a bicycle equipped with fully operable pedals and an...

Yeah but your example is just there for argumentation. You are willfully ignoring obvious reality by citing an ancient outlier. A 48v bike has a 54.6v charge at 100%. In order for a 48v system to fit under the 750w absolute limit, it has to have a controller whose PEAK output is no more...

The throttle issue is nothing. The law allows a walking throttle which means a bike can be sold with a throttle, and can have a throttle. People will still be unlocking them and nothing will change. The real issue with this legislation is the absolute 750w cap on power output. I was pointing...

I try to always recommend against it as the builder has to assemble it exactly right and then ride it exactly right for it not to be a motor and drivetrain killer.

Based on what I saw in the product pics at the Wilier site, they use 32 in the back and 28 in the front on the factory bike. My Guerilla Gravity enduro 29er used a DT Swiss factory wheelset with 28H front and rear and frankly I never trusted it, even though it never failed me. I replaced the...

Ebikes tend to be heavier, and faster. So they hit things harder. More spokes are not a bad thing in that scenario. I personally typically use 32 hole rims, and completely stay away from bladed spokes (or God forbid c/f bladed spokes). Also brass nipples not alloy. And heavier double-butted...

Because you can essentially never say for sure what level of quality control went into any battery blender, and the risks of a bad parallel connection can literally be catastrophic, a blender is a pretty dangerous risk. The one exception to this are the DateX blenders, but they cost quite a...

The builders who swear by low speed-count setups are typically also swearing by 8s freewheels and Tourney or Altus derailleurs. And they're throttlers, not cyclists. They see more expensive 10s+ setups as delicate and don't understand the 'more durable' part. See above. This is completely...

Yeah I am primarily a pedaler, and my daily drivers nowadays are cargo bikes that haul a lot of weight on Costco and grocery runs. I'm doing an online order pickup at Home Depot today in fact. And I live at the top of a hill, so I make VERY good use of that second powered wheel. A 2wd ebike...
