    Why not comfort bikes?

    When you have 20lbs of batteries and 25lbs of additional weight (motor, controller etc) you need good, long travel suspension to protect your rims. This is why mountain bikes are the number one solution. I have a 200mm travel bomber fork in the front and 1800mm travel in the back. Sometimes when...

    Lithium Batteries Shipping Rules Discussions

    OKI, but what happens in practice when batteries are inspected by anybody at the border or later? Do they arrive to the recipient? My problem is very simple. I can buy really good batteries from a person in Europe. I know the guy, he is a geek, sells only perfect stuff but, as a nerd, he...

    Lithium Batteries Shipping Rules Discussions

    Well, not necessarily. I am the recipient of the package so how can I be responsible for the sender not putting a sticker on the box?

    Lithium Batteries Shipping Rules Discussions

    Yes, I am also interested in practice vs theory. Theoretically I know about all those hazmat and UN9473958375289356345893465 regulations, but how does it look in real life when you ship by sea, where the requirements are not that strict. I have managed to ship my ebike on a pallet with my other...

    Source for bike parts in the USA???

    So I moved to the US with my family and I left my bikes in Europe due to transport costs and restrictions. My plan was (and is) to build three bikes for me and kids. Well, I arrived, opened Amazon (assuming they have everything), typed some BMS, a square wave controller, Mxus V3 motor, Li-Ion...

    Consequences when I don't declare batteries in shipment

    Hello Anybody working in a freight company? We all know the rules when shipping batteries. Forbidden on passenger planes, a little bit allowed on cargo planes and a bit allowed on ships. I am shipping my e-bike from Europe to the USA and the battery pack is permanently attached to it. If I...

    Newton-meter confusion.

    Hello I am building my e-bike and my choice is a mid-mount motor because of better handling and low unsprung weight of the rear wheel. However... I am having problems when it comes to choose the right motor parameters. I want a bike that can go around 50km/h on a 24 inch wheel at the back. No...

    Help with part selection for my first e-bike

    No worries about that. I plan to use my bike on the streets and it's legal here. I live in a residential area with little traffic so riding my bike just like a motorbike or car will be safe for me and other people. My house is adjacent to a large forest with singletracks and wider gravel tracks...

    Help with part selection for my first e-bike

    Thanks a lot for the replies. I am thinking about the cyclone 3000W motor. Seems pretty simple and if I install a big cog in the back it might even run only on its incorporated planetary reduction. Are there any other battery options which can be a match to LiFePO4? From what I see on the...

    Help with part selection for my first e-bike

    First of all I would like to say hello and big thanks for being such a great community. I have been reading this forum for a few weeks and I have finally decided to write my first post. I don't want to reinvent the wheel so I've decided to ask for your opinion on preferred motors and batteries...
