Re: Ebike kit I can carry in airport and charge my Macbook

It is riding decently, but you will have to help it.

I agree it is the best solution for your requirements. Carrying 2kg in a travel bag, to ride easier at destination, is a positive trade of human energy if you calculate it in calories. Next best thing after renting a scooter. :D

Re: Can anyone recommend a charger?

After appropriate battery capacity for your needs, your next criteria is a reliable, adjustable, relatively fast charger according to the battery C-rate. You just don’t know yet, how important it is. Once you started to ride, you don’t want to miss your bike a week for a fried charger. See where I ...

Re: Considering getting an ebike instead of a car

Yeah, sometimes see those behemoths on I-95 being transported between NE and FL either way depending on season. Crazy. We were the other end of the state and had 23 foot fishing and diving boats. Not as crazy as Miami for sure! The boat I have now, was purchased in Miami where it had crashed on the...

Oh! Miami is crazy. I’ve seen people carry their big cruisers on trailers there. Hard to understand for me, who had never transported any bigger than a Laser, on rare occasions.

Re: Considering getting an ebike instead of a car

...you aren't going sailing anywhere except your home dock unless you have a motor vehicle to transport the boat. And that home dock had better be within biking distance. LOL.

Yep. Me too.

I started with a Laser in the 70’s, then small cruisers for family, now sailing an old 20’ Red Fox that served me well but needs a rebuild. I want to go back sport sailing, never had a cat.

I'm just saying if its possible, learn to drive and get the license. It will come in handy some time. Like when you have to move, you can rent a truck. You fly somewhere, you can rent a car if the rest of the trip is farther than you can take a taxi. A lot depends on where you need to go, out west,...

Re: Has anyone ever seen this type of winding before?

Not sure wether it is a motor built with parallel stators/windings, or parallel connection of opposite coils like induction motors. The later does lowers resistance by 75% as compared to serial connections. It does make better power available at higher speed, with improved efficiency. Those are fed ...

Re: Considering getting an ebike instead of a car

In a big city, driving a car can drive you nuts, and winter makes it even worse. Cars are addictive because people enjoy being disconnected from reality. It is a drug that is making them selfish, agressive, and stupid. When you watch DashCam footage on youtube, you can see the effects of this addict...

Yep. We need feedback from someone who had built an ebike with LITO. It will remind us the good old time of lead-acid. :D

All of us are waiting for the day batteries will improve density, because compact lightweight batteries are every ebike builders dream.

Re: Very Impressed by fast motor winding with gear reduction vs. Slow motor Winding without gear reduction

High power charging does require big and/or expansive charging stations. You can’t pull much more than 2kw from a 120v outlet, and that is when the circuit is not feeding anything else. LTO may have a future for cars, but ebikes have limited space and weight requirements. Ebikers who charge fast are...

Re: Cleaning inside of motors

Curious what’s the max phase amps you pushed a QS205? You got this wrong if you think power can be pushed in a motor. The motor does pull current according to the resistance that it has to fight. You decide only the limit that your controller will allow it to pull. Give it full throttle acceleratin...

I never do that, even with big motors that last 20,000 miles. I hardly clean them outside. Maintenance is doing consistently the things that need to be done before they cause problems. Doing things that are not required is obsessive care, typical of those that prefer tempering than riding, or have n...

It is your wheel alignment that you need to work on. The simple and only solution is to make it a permanent fit. Hub builds need torque arm or torque plates, or custom dropouts. When alignment is a problem, forget the torque arm. Bolt-on torque plates, or custom dropouts, are giving you the opportun...
