I'm not an engineer, that would be their job. I would ask that they do NOT patent the idea or at the very least make the patent available to other manufacturers. It would be in the best interest of the industry.

I'm not familiar with the bike and hesitate to make any comments. Sorry. The 48V will support a 750 watt motor. On a big tire bike, possibly in snow, you need the horsepower. Mid drive or a geared rear hub, no direct drive motors. There's more then cold you have to consider..

In a In a perfect world you would take the heat from the motor and route it along the wires coming into the hub and transfer to the frame. In the summer it would cool the motor and in the winter would warm the frame. Don't know if it can be done

You have a situation that IMHO requires building your own bike. Personally I would get a nice fat wheel bike, maybe used, and a 48V 750 W rear wheel kit from a quality manufacturer, I like a small company called Bison Moters but there are others. Get a triangle bag for batteries and controller...

Put your spare battery in a cooler with a microwavable hot pack. They make "coolers" to transport food that do this, like a pizza delivery guy would use. The ones we use (for food) are the size of a casserole dish

When it g Insulate the downtube. That is the best thing you can do to keep the tube batteries warm. Store it inside. Crazy idea. If it's really cold make a heating pad out of rice that fits the frame, heat in a microwave, put around the tube and use an elastic bandage to hold it in place...

I built my bike using a powered rear wheel kit and store the controller and batteries in a triangle bag. batteries will be kept warm from the waste heat generated by the controller. Any way to use that heat to warm the down tube? If the downtubes are aluminum they need to be insulated, think...

I am taking a 48V powered hub and renting a bike to install it on. I agree you cannot take typical ebike batteries. You can take 4 -12V lithium batteries and run them is series. to make a 48V battery All of my batteries are under 100 Watt Hours. That is the criteria. They use laptops as an...

Not sure where you got your information from. I checked both with FAA and Southwest Headquarters. You cannot put any lithium batteries in checked luggage. Not even e cigarettes. You can carry the batteries for any item as long as each is under 100 watt hours. FAA says as many batteries as...

Yes. ZZipdesign in California. If he made it so you could easily take it on and off then you could use it only on bad weather days when no one else is using the bike path.

A flip down visor. Attach it to your helmet - it has an elastic band. $4 from Harbor Freight https://www.harborfreight.com/face-shield-with-flip-up-visor-62995.html

Hi all, I'm taking a 48V kit to Costa Rica on Southwest and found a way to bring a battery while complying with FAA regulations. Dakota Lithium Batteries makes a 12V 7ah lithium that looks like a lead acid battery. I got four of those and will bring a frame bag and harness. I will hook them up...

Thanks. Great info and I really appreciate it.

Once the bat LOL. You will get the bug and soon have a bigger bike.

Thanks for the clarification. Is a 3450 mAh cell considered high capacity?

That's why I'm such a big promoter of the kits. You can put them on any frame you want. Frame cracks? Go on craigslist and buy another bike - I see nice Trek and GT bikes for under $100 all the time. Motor burns up? The importer I buy my 500W motors from will sell a new rear wheel with Motor...

Do you know for sure that Panasonic doesn't build a 3450 in Vegas? Do you purchase lithium batteries for a living or work for Panasonic? If you google 3450 lithium cell you will see that it is available. Just because you don't know doesn't mean it isn't available. 95% of the components that...

For ebikes to become "normal" and be used as transportation they need to provide more then you and I need. Not everyone loves bike riding and riding in bad weather is an objection that must be overcome. For you the cost is a lot but for a kid who is paying $250 a month in car insurance and...
