a good illustration of why it’s such a stupid point that “even acoustic bikes can go fast downhill so e-bikes aren’t a problem.” going extremely fast on a bike requires focus, very particular circumstances, and some skill, especially past 35 or so. the fact that your incident (which is extreme)...

how heavy are those guys? i really disliked the weight of the 510s.

I generally agree, I just think we need a “class zero” which is so innocuous as to be permitted absolutely anywhere that bicycles are, by riders of any age, without question. vehicle weight < 40lb, no assist over 15 mph, peak power < 300w, instantaneous power < 2x human power at that moment in...

fair point! but I think there’s a big difference between the way crimes like assault, fraud, etc are policed and prosecuted - which costs a huge amount of money and relies on incarceration as the primary punishment - and vehicular offenses like speeding, which pay for their policing through...

the enforcement approach is difficult without some combination of a) licensing, b) registration, c) use fees or stiff fines and d) a significant police presence on vehicles with similar abilities. are we requiring people to have a drivers’ license to ride an e-bike? i guess there could be a law...

I use pedals like that on my commuter, but the whole surface is that grit material. no risk to shins and works with any shoe. https://www.motobicycles.com/en-us/products/moto-reflex-flat-pedale not terribly suited to trail riding, but very utilitarian, safe, grippy, no nooks and crannies to get...

i doubt that’s going to be a huge problem - california is a very big state with only three neighbors, and the amount of cross border riding over the sierra and through the deserts is nearly nil. the oregon border, a few. sure, people put bikes on cars and drive hundreds/thousands of miles but...

sure, 600w + 100-200w human input will take you up a steep hill… but it might take a motor rated for much higher than that to achieve 600w at a relatively slow hill climbing speed, especially with a hub drive. and with a mid drive, you’ll need the right gearing, which many e-bikes don’t have.

hard to say always, but most of the time the average reading was too high for either heart rate correlated with other PMs, the actual climbing rate (if you know weight and slope … the amount of work done is very simple), or power pedals when i tried them on the creo.

what kind of power readings are you seeing with the motor off? say, riding on level ground at 16mph with little wind and a steady HR in the 90-130 range? my conclusion after quite a bit of mucking around with the data was that with the latest firmware and the motor off it was within 10%, but...

https://www.bicycleretailer.com/industry-news/2024/12/31/super73-sued-over-legality-its-e-bikes-california I have to assume most of these outfits are just going to stop selling bikes in California. They’ll be like fireworks.

the forum has an ignore function :) it does make the thread a little harder to follow sometimes.

To me, it’s really simple. Bike infrastructure (what little of it we have) was designed for vehicles with a certain performance envelope, which is approximately what a reasonably fit human can provide. Not a world tour rider in a peloton at full blast, but a reasonably fit human on a reasonably...

No, a few small fire trucks could not have saved the entire area. Your politically motivated lies are offensive and diminish the weight of everyone’s suffering.

Much ado about nothing. the e-bike market in North America is strong and growing. some players will make it, and some won’t, the same as any market. perhaps people don’t want 75lb, $10,000 “Bicycles” with lots of proprietary parts.

By volume, possibly. I’d be surprised if it was that much by value, with the average name brand bike shop bike costing many times as much as the “bike shaped objects” you’ll get from some of the big box stores. the average unit price of the 14 million or so bicycles sold in the US last year is...

some pretty cool features. easy to get 12v power on an e-bike, but those fat cables going to the lights up front don’t look too easy to integrate. 240g total weight, not horrible! i’m guessing it would actually work with only the rear piece, since communication with the app/head unit is by BLE...

no. you do not need to worry about the rims in any way unless you’re a heavy rider. 27 lb is not a particularly heavy bike, except when compared to lightweight road bikes, but even there the 13lb difference between your bike and a very light bike is not significant compared to the rider weight...

right, there are definitely localized areas where streets are close enough to 45 degrees to limit the usefulness of the cardinal points. a good chunk of our street grid is turned 44 degrees (following the original spanish road from harbor to mission), and everyone in the know knows which was is...

on a related note... it really surprises me how many people don't know which direction is which. sometimes when giving someone (simple) directions, i'll say "go north x blocks then turn left." ... "which way is north?" given that most american cities have large areas of roughly n-s-e-w street...
