    Customer just dropped off a 137-pound "e-bike" (which is
    more an electric motorcycle). Peak output 5000W, zero to
    20mph in 2.87 seconds, 50mph capacity with 72V batteries
    rated for 72AH!

    I'm dealing with an hydraulic fluid leak so not complex but
    I was amazed if not astounded at the whole thing.

    We've always done ancillary work; wheelchairs, tires on lawn
    & garden equipment, sidewalk bicycles & tricycles for
    toddlers, recumbents, some moped work. Related technology
    includes our design and fabrication of a sprocket and chain
    drive (essentially treads) for a winning vehicle at Robot
    Wars, various cable control systems for all sorts of
    machinery and even some surreys.

    This one is a real outlier!

    By the way, top gear on the thing is 58x11.

    Does it require a driver's licence, lights, insurance and a tag? It

    As we've discussed, the technology and products are way
    ahead of the culture, policy, statutes and ordinances. The
    whole area is shades of grey and enforcement of present laws
    is mostly out to lunch.

    "this bike doesnrCOt just accelerate; it launches like a bullet"

    Takes me back to a Paris experience with my wife. We were walking
    from the Eiffel Tower to the Arc de Triomphe (sp) and started down
    the Champs. Having watched many TdF finishes, I got the bright
    idea we ought to rent e-bikes and do a lap ourselves. First
    timers, he hopped on, and were immediately terrified by the
    unexpected acceleration as soon as we so much as started them. In
    fact, Kathy took a spill, so we quickly abandoned my not so bright
    idea.

    Sadly, this is probably of the domain that requires some kind of

    Does depend on the e bike, certainly if it has torque sensor should give a
    much more measured response after all power is nothing without control, and
    E MTB need control for technical climbs just booting it into turbo works on fire roads but not there!

    Generally itrCOs cheaper/older bikes without a torque sensor that will surge.

    IrCOm guessing not within last few years? As IrCOd expect most hire e bikes to have torque sensors now as it gives a much smoother ride, and folks are
    riding the last mile or so not tearing up the road in such bikes, I pass
    them quite comfortably on the roadie, as they top out at 15 ish mph and
    while itrCOs possible to pedal them beyond that would need to be bit of beast to do so!

    They are tolerated to a extent in the uk as itrCOs largely the delivery
    riders, are in uk law illegal mopeds as they are in EU and US though US in particular classes such E motos as E-bikes if they stop at 30mph which is a
    bit of mess in terms of regulation aka the class 1/2/3 system how they
    expect any police etc to know the differences particularly on the road?

    In the Uk throttle (bar one that only operates 0-3.7mph to get folks
    started) means itrCOs illegal and police absolutely can and do use it to identify illegal bikes, which they will no and then do sweeps and confiscate/fine riders, IrCOd assume the bikes are broken up as canrCOt be made legal.

    I believe some states have started clamping down though since they allowed folks to have mopeds without regulations I think will be hard sell but
    letrCOs see.

    they are heavy even the non electric ones, and have quite upright position, they certainly donrCOt handle well, and even if used to E bikes, they will
    push as you pedal or even just move the pedal.

    IrCOve used e bikes but not the dockless ones, have used a few hire bikes but been a while now, the Boris bike I remember having fairly ornamental brakes
    ie they had little effect, though IrCOm used to disks and have been for
    decades as well MTB have had them for ages.

    The last mile etc sort of journeys just isnrCOt how I travel, if I use the
    bike IrCOm likely to ride in and so on.

    My wife rented an E bike in Arles last week, and she very quickly
    decided she'd switch off the electric for 80% of the journey because it
    was very hard to ride at the speed she wanted to ride (last half hour
    into head wind, the power helped both her and slip-streaming me).

    ThatrCOs certainly not my experience of E bikes, some have a bit of surge
    when you move the cranks, others itrCOs more controlled and more well natural feeling, none have been difficult to ride at certain speeds the utility
    bikes tended not to want to be hustled along but thatrCOs the same with non E bikes of the same type.

    Clearly there are in some places some very odd E bikes out there
    particularly the cheap or very over hyper hyped stuff, see hub less wheels
    and so on.

    But that doesnrCOt seem to be the norm, even the dockless stuff seems to be broadly easy to ride.
