Re: UK Law regarding E-Bikes

Fair enough. But your odds of getting killed in a traffic accident (on a population basis) are about five times greater in Costa Rica than in the UK . Pick yer poison. The way I ride the odds are so close to zero that any stats you looked up don't apply no matter what vehicle I'm operating. The poi...

Re: UK Law regarding E-Bikes

I'd never live there with those ridiculous laws written with the help of hard core cyclists. The law here is above 5000W electric motor output makes it a motorcycle, and under 5kw output makes it a moto-bici, that is legal to operate. No license, no registration, no inspection, no silly pedal requi...

Re: Would ballast disconnects be workable reusable connector?

i can't find any amp rating on that page so i don't know where that 6A number came from. Keep scrolling down and you'll find the 6A rating on the photo/advert at the bottom.

Re: Alternator to Electric Motor - Pulley Removal

I wouldn't use an actual shitty rusty bike. I'd want to bike to still be safe. I'd shitty one up artificially using cocoa powder or something similar like this: You might also consider repainting with enamel and a paint brush. Be sure to induce plenty of drips. That should convince people that the b...

Re: Bicycle Speakers

So if this is true for cars, I shudder to think how much more statistically dangerous it is to cycle while listening to music, an audio book, or anything else, rather than simply focusing on the environment. There is a fairly significant difference between listening to an audiobook and playing a li...

Re: Bicycle Speakers

Wow. That's a horribly misleadi...

Re: Small hub motor

Given your fairly low amount of riding annually, I think that you are likely to find that you'll be running some kind of power all the time once you get the bike converted. What adding a motor tends to do is expand your range and inclination to ride since doing so isn't necessarily a physical ordeal...

Re: Small hub motor

I guess people need to be honest about their abilities before building a lightweight assist system. Which brings us full circle; I guess that all depends on the person. Exactly. All I (we) can hope to do is point people toward good information. They have to decide how applicable it is. And I agree....

The best race driver is the one that never presses the brake and acts like a lemming PMSL. Sure. And they build race tracks for that or partition streets from regular traffic when they race on streets. Racing and regular day-to-day driving do not mix well. Agree that was sarcasm by the way ;) OK. M...

A few of the guys who built lightweight road bikes carry the battery in a backpack with a quick release electrical connection of some kind. They seem to think it is a valid concept.

Re: Small hub motor

I don't have the background to help with the motor. But I will suggest that a rear motor will look more traditional (tucks in behind the cassette and disc nicely) and probably give a more traditional riding experience (power applied to the rear wheel) and it really isn't a lot more complicated. Also...

Re: A few questions for my first ebike build

But bear in mind that even the 1000w kits are illegally fast in much of the USA. Not that most cops care much, but just sayin. The newer standard in some states is 28 mph, with PAS, no throttle. Others stick to the 20 mph rule. Sorry if I'm being nit-picky, but most of those laws actually specify t...

Re: High power ebike means none of the rules apply to me

I've seen a video from the UK where a driver intentionally rear ends a cyclist that he found annoying. So I'd be careful about generalizing from one example. There is a difference between careless driving and intentional assault with a deadly weapon. The point of the anecdote was the dangers of gen...

Re: Hub motor industry dying?

I think a downside with the small wheel would be increased cogging torque when unpowered and I guess when powered too, cogging with the 1/3rd unpowered teeth. in comparison to a bigger wheel diameter that would need less rotations to get the same distance. whats a low cogging hub motor? Based on my...

Rear wheel axle looks pretty similarly placed in relation to saddle as most bikes. No, the chainstays are clearly shorter. But like I said, the bike will probably be nimble and fun.

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

I assume the 3 pin JST plug with red/green/black wires is the throttle, because none of the other plugs seem right for the job. With the controller powered up, I'm getting 4.5V red-to-black, 5.0V green-to-black, and 0.5V green-to-red. My KT controller's three wire throttle colors are red, black and...

Small wheels and seat nearly directly above the rear wheel axle will probably yield a pretty harsh ride. OTOH, the apparently short wheelbase might be fun

Step down converters are small and inexpensive. They open up a wide range of 12v (or other voltage) options.
