    the math of hill climbing

    State of charge vs. voltage for a given battery type is pretty well understood and reliable, if not terribly accurate. Another way to figure out for us backwards Americans is HP=F*V/375 where F is the force in pounds and V is velocity in mph. For the additional power required for a hill climb...

    n00bie from New Jersey

    Sounds like me... What part of NJ? Didn't have the "hills" you speak of when I lived there, but that was down the shore.

    Ebike rack

    I ended up buying a Rockland 2-bike rack (Amazon) which as far as I can tell is identical to the Young Electric rack (and probably made in the same factory). Easy to assemble, reasonably rigid, though not as rigid as the single rack she was using. Used it for the first time today to take the...

    Took a ride today with Mary on the Nyack Beach (NY) bike path which runs 5 miles along the Hudson River from Upper Nyack to Haverstraw. A very nice ride. That's the new Tappan Zee Bridge (which also has a bike path) the the background. Last time I was here was 50 years ago with my parents and...

    Folding e-bike for small airplane

    Onewheels are popular with the bush plane crowd. I was thinking about an electric unicycle, but even that wouldn't fit in the plane I have now.

    “No e-bikes allowed”

    Chargers and other devices that handle a wide input voltage range are probably using switching power supplies, so there's no extra current that has to "go somewhere".

    Short ride today up the old camp road past our cabin in NY. It goes to an abandoned boy's camp that closed in the late 1970s. There's this isolated stand of pines in the mostly deciduous forest. 120 years ago there were houses and farms here, now it's state park lands.

    best security ideas for ebike

    Probably typos but people should understand the difference between Watts (W), which is the rate of energy consumption, and Watt-hours (Wh), which is the total amount of energy used or stored. A device drawing 6W for one hour uses 6Wh of stored energy. 6W for a week is 1008Wh. Though a 1050...

    Light(est) small Ebike with throttle for disabled wife (5'2")

    My wife is 5'0" and fits her Zugo Rhino well. However, like most fat tire bikes it's not lightweight, but she wanted something that could handle sand and gravel roads at campgrounds, with a big battery for useful range.

    Happy to be on the forum!

    Welcome! When I was in Syracuse for a few years with a bicycle as my only means of transportation, it was about getting around town at a constant elevation, i.e. going around instead of over the many small hills (called "drumlins") the city is built on. An ebike would've been nice, but they...

    15 MPH E-bike and Scooter speed limit announced for NY City by Mayor Adams

    This. That common definition should include what requires registration and/or licensing and what doesn't, then the individual states can make operating regulations to suit their particular needs. Just like a car registered in, say, New York is legal to drive in California, though you have to...

    Interesting Times for Electric Bikes

    No, there's a special level level of hell for impolite riders... where all rides are uphill, into the wind, on a heavy ebike with a dead battery.

    15 MPH E-bike and Scooter speed limit announced for NY City by Mayor Adams

    NY State technically allows class 3, but only in New York City. Throughout the rest of the state it's class 1-2 only, and only on roads with 30mph speed limit or less. By many measures, NY is the least free state in the US.

    Rode up the old camp road to the lake up the valley from our cabin, upstate NY. Not far, only a couple miles each way.
