    To reuse a quote from a different transport sector:

    "Horsepower is how fast you hit the wall. Torque is how far you move it"



  • Registered Users, Registered Users 2 Posts: 14,678 ✭✭✭✭CJhaughey


    As with most things it depends, some hub motors are direct drive, some are geared and some are multi geared with Roloff or Enviolo hub shifters and a Mid drive motor running through a belt drive setup (high end stuff like Reise and Muller) the torque from these is astounding and makes the cargo bikes they sell very able to shift large and heavy objects.

    There would surely be an argument here that if someone is overweight, then a motor bigger than 250W is not going to help them from a health perspective 🙄

    I was driving back fron Howth the other evening, two lads on an e-scooter with slightly bigger wheels but no massive. Saw them in the village and they took off towards Sutton. Couldn't catch them, traffic moving around 40-50kph. They must have been hitting 45 in places with two lads (late teens or early 20's) so not kids. They thing was flying and definitely not 250W. Braver than me with wheels that small.

    But that's at a time when they are technically illegal and there are few of them. What kind of numbers will we get when they are properly regulated and there are far more of them?



  • Moderators, Category Moderators, Arts Moderators, Sports Moderators Posts: 52,216 CMod ✭✭✭✭magicbastarder


    I don't think you could say there are currently 'few' of them, tbf.



  • Registered Users, Registered Users 2 Posts: 32,136 ✭✭✭✭is_that_so


    In comparison with other forms there are few of them and you'd expect quite a surge once the regulations are sorted out and in place. I've nothing against them being used but there are some very zippy ones out there, which is problematic, and some road behaviour that is little more than spur of the moment reaction. Ultimately there may be issues for pedestrians.



  • Registered Users, Registered Users 2 Posts: 9,651 ✭✭✭Macy0161


    I think you're making a leap that the incidents/ collisions were all the fault of the person on the escooter, and there's no breakdown of those involving pedestrians. We have no idea from the data as reported.

    We also can't really extrapolate on seisures - how many would be legal (or not) under the regulations; how many were for general anti-social behaviour where those involved had scooters; how many were as a result of failure to pass the "dont be a dick to a garda" test.

    Like, it's typical Irish journalism, but not really the basis to draw any proper conclusions.



  • Registered Users, Registered Users 2 Posts: 2,514 ✭✭✭JMcL


    According to another Times article linked from that one (https://www.irishtimes.com/ireland/2022/08/10/two-deaths-and-42-serious-injuries-caused-by-collisions-involving-e-scooters-since-start-of-2020/) there've been 2 deaths and 42 "serious" injuries in the same period related to scooters. There are of course caveats in that the data came from AGS, and there was a discussion elsewhere in the forum about the statistical quality of same. Also it comes with a warning about the usual bemoaning in the article on lack of helmet use despite most of the injuries seeming to be fractures. Not sure how these numbers would stack up against comparable statistics for bikes were they to be scaled, though I suspect that


    According to the article MB posted, there've been 269 seizure since early 2020 - mostly around Dublin, I'd imagine to get seized you'd have to be taking the mick really, but in the legislative vacuum you're always at the (probably small) risk of running foul of some Guard that got out of the wrong side of the bed that morning

    Apologies if asked before.

    Was looking at the xiaomi mi pro2 scooter.

    What do people think about it being non waterproof? It seems a major drawback given the chance of being caught in rain.

    Thanks



  • Registered Users, Registered Users 2 Posts: 14,157 ✭✭✭✭Flinty997


    Anecdotally some of those reporting they had scooters seized were just commuting. I think they just unlucky to get caught in temporary surge of interest from Garda. Usually in one location.

    The stats on normal cycling fines seem to suggest similar.



  • Moderators, Politics Moderators Posts: 42,840 Mod ✭✭✭✭Seth Brundle


    I believe that they are "somewhat water resistant" but not waterproof.

    To me this means that they won't last long in an Irish autumn or winter.

    If you got one, can you afford to replace it?



  • Registered Users, Registered Users 2 Posts: 7,820 ✭✭✭Tigerandahalf


    It makes me wonder. A lot of these are designed for drier climates like southern Europe but they also get rain there and given that these are often parked outside rain ingress must be an issue. I don't really understand why something like that wouldn't be made fully waterproof.

    Looking at the scooters I am not sure where the rain would get in - the display on the handle maybe?



  • Registered Users, Registered Users 2 Posts: 32,136 ✭✭✭✭is_that_so


    There are no regulations so other laws are being used legally, probably as the mood suits Gardai. I wouldn't get onto the blame no blame analysis of incidents as it's really how many is the key data to get a sense of what levels there might be once there are regulations and there are a lot more of them.



  • Registered Users, Registered Users 2 Posts: 1,759 ✭✭✭lalababa


    You'll have to bate the car drivers out with a nailed stick to reduce congestion/pollution. So tis looking like a congestion charge, and should be a higher charge for single occupancy.

    Public transport ..for this country read bus. Should be upgraded (so it actually works and is pleasant) and should be free....for awhile.

    250w pedal assist (15mph) is grand for anyone doing anything. Small foldable electric bikes are grand . Electric scooters are illegal and this should be enforced. They have crappy wheels and are unstable.

    So saythed me the great.



  • Registered Users, Registered Users 2 Posts: 9,651 ✭✭✭Macy0161


    Any/ all could (should?) be seized at the moment as they are illegal. It's just another traffic law not enforced. I still don't really see how we can extrapolate at the moment without more detail. Will some being legal mean more uptake, and more awareness, and a critical mass that makes them safer? We don't know



  • Registered Users, Registered Users 2 Posts: 32,136 ✭✭✭✭is_that_so


    Seizures seem to be at the whim of Gardai IMO. Met someone recently who was upset to have had the scooter confiscated but language barrier didn't clear up why.



  • Registered Users, Registered Users 2 Posts: 9,651 ✭✭✭Macy0161


    Totally. And I'd guess that a fair amount are around other anti-social behaviour (eg gang of teens hanging around causing other issues) rather than randomers commuting/ going about their daily lives.



  • Moderators, Technology & Internet Moderators, Regional South East Moderators Posts: 28,563 Mod ✭✭✭✭Cabaal


    Always find it amusing that gangs is used so much when teenagers are mentioned,

    But you wouldn't use it in relation to basically any other groups, "I met a gang of women on the street lastnight".

    Anti-social behaviour typically meaning teenagers socialising anywhere they're legally allowed to be also.



  • Registered Users, Registered Users 2 Posts: 9,651 ✭✭✭Macy0161


    It can also mean vandalism, intimidation, and hanging around places they shouldn't. But I would say the main bottom line is you wouldn't be confiscated if you didn't fail the don't be a dick to a garda test tbh.

    btw I'd use it in wider context than just teenagers. "Who was on the spin?" Me: "all the usual gang"



  • Registered Users, Registered Users 2 Posts: 650 ✭✭✭inigo


    Can I ask a technical question here?

    The new Halfords scooters are out now, including version 2.0 of the model I've got. One of the main differences is that the new version has cruise control.

    Does anyone know which part controls it? Throttle, controller, both, none?

    It would change my life if I could adapt mine. My hand gets numb every time I ride it.



  • Registered Users, Registered Users 2 Posts: 31,275 ✭✭✭✭Lumen


    It should be but is isn't. I recently bought a very premium 250W e-scooter (claimed) that also claims to boost to 500W, and it won't go up a moderately steep hill at any speed. By which I mean it stops.

    Based on my experience there is no legal e-scooter which is usable except on flat terrain.



  • Moderators, Category Moderators, Arts Moderators, Sports Moderators Posts: 52,216 CMod ✭✭✭✭magicbastarder


    worth noting that my comment about power was in relation to bikes, not scooters.

    it should be straightforward enough to calculate the power required to go uphill, though? perhaps there's an issue with the motor.

    e.g. take a climb 2km long with an elevation gain of 100m (5% gradient); to do that at 15km/h would take 8 minutes, and assume a combined scooter and rider weight of 100kg.

    total potential energy gain is - as near as makes no difference - 100kJ. so that would require a power of 208W for the potential energy aspect; so 250W should be enough for that, which is a steep climb?


    TL;DR - 250W should be enough for a 5% gradient.



  • Registered Users, Registered Users 2 Posts: 31,275 ✭✭✭✭Lumen


    I guess the issue is lack of torque, if that power is made only at an unsustainable speed. The scooter will do 25-30kph on the flat.



  • Registered Users, Registered Users 2 Posts: 12,518 ✭✭✭✭Varik


    Gravity would be exerting ~50N for 5%, ~100N for 10%, and ~150N for 15% for 100kg rider+scooter. How much torque acting on motor for it to counter that is dependant on the wheel size.

    So whatever your wheel size radius is in meters by those is what min torque you'd need to even move.

    For 220mm wheel that'd be about ~5.5Nm, ~11Nm, ~16Nm. 16Nm is what's rated on the 250W sustained 500W max scooter I've seen.



  • Registered Users, Registered Users 2 Posts: 713 ✭✭✭LeeroyJ.


    I bought one of these back in 2018 to commute to and from work, at the time it seemed like legislation would come in very soon. 4 years later, still waiting, sold my Scooter in the meantime and bought a car for the commute. I wonder how many other people are in the same boat. Perfect transport to get cars off the road, but the government has been dragging it out forever now.



  • Registered Users, Registered Users 2 Posts: 30,193 ✭✭✭✭zell12


    Legislation should be passed by Christmas that will ban certain types e-bikes from cycle lanes.

    Is that not already law, it's just not enforced.
