Re: Building a 72V ebike

Do the laws in Belgium allow you to run those speeds? I'm pretty much a libertarian but if my employment depended on running an illegal vehicle through a major metropolitan area I'd think twice. This from someone who regularly commuted on a technically illegal vehicle. You can more easily get away w...

Re: Burning Man Electric Couch.

Thanks for this one. I got a big laugh at the 30mph couch line. Please wear excellent gear and find a good empty road if trying it out at those speeds. And get video.

Re: Linear pull, Center Pull, Dual pivot: What is your opini

I'd also respectfully disagree that any lever can work well with both cantis and linear pull. The cable travel is too different. A linear pull lever won't have enough leverage on a canti and a standard lever won't have enough travel for a linear pull. It can be made to work, but not well.

Re: Linear pull, Center Pull, Dual pivot: What is your opini

Linear pull are usually easier to set properly and keep adjustment. Some cantilever brakes can be as good, but often require more fiddling. Both need proper pads for best effect.

Cordless lawnmower SLA > lithium upgrade advice

Just moved to a new house, and now I have a 1/3 acre property with more grass than I can handle by dragging the 100' extension cord around. I do however have 116 tested makita cells from DrBass in the garage from my earlier plan on building myself an ebike battery that got long delayed (something ab...

Re: Death Bike vs. Tesla Model S P85

What I love is that you're cruising back to the pit at a drag race, and your friend can call out your time to you and you hear it. Some gearheads may miss the racket of racing engines and I'll never begrudge them that, but I never will.

Hyperion 1420i voltage readings -- something I'm missing?

I purchased the charger about 5 months ago for my very slow (I have small children) toolpack 14s battery build.

Re: Best motor for steep city hill low speed climbing?

The distance makes a huge difference. Those are short hills, so if you're willing to push on the pedals to help the motor up the really steep sections, almost any hubmotor kit will make your ride easier because you'll be less tired from grinding up the steady climb. I'd guess you'd be fine with a si...

We're certainly hurtling towards a tipping point that no one would be able to see until after it happened, but I'm not losing hope just yet.

Re: to eat or not to eat.. meat.. was Best Burger & fries?

In epidemiological research on the effects of diet there is a known issue called the healthy user bias. Essentially, it is that people who follow a diet widely considered to be healthy, such as a vegetarian one, are also more likely to do things such as exercise, spend time in the community, drink m...

Re: to eat or not to eat.. meat.. was Best Burger & fries?

I don't have a problem with suggestions that eating less meat than the average North American is probably healthier, or that you can get big and strong on a vegetarian or vegan diet. I don't think it follows that a vegetarian diet is superior to a quality omnivorous one. personal anecdotes or exampl...

Luke I do think you are conflating the health, ethical and environmental impacts of meat eating with those of industrial agriculture. We're omnivores. Just as cows are grass, not grain eaters. Pigs and chickens are also omnivores, but are advertised to the ignorant as all vegetarian feed as if that ...

if your commute is flat, a single rear direct drive motor is easily the top option. rear geared would also work, and be stealthier but ultimate reliability goes to direct drive as noted above.

Re: Any way to do 100 miles or more with an ebike?

Pedaling saves your ass. Whenever I read these threads about getting sore in the saddle for long rides I have to remember it's because folks aren't really pedaling. Pushing on the pedals lifts your ass off the seat.
