Isn't there a clause somewhere stating that the pedals must be able to transmit direct power to a wheel for it to be considered an actual "ebike" and not just a moped?

I'm aware there's all sorts of red tape in bongistan/yurop to the point where anything other than very low power "give granny a helping hand up the hill" "pedal assist" is basically verboten, but can't you pretty much do what you want in shartmerica (where I assume this bike is)?

I know someone who fucked themselves up BADLY on an eMTB. he isn't even sure what happened because his memory of the crash was erased. eMTB should require a license. it would save the trails and keep people from killing themselves. MTB had somewhat built-in learning curve keeping unskilled riders off of big trails, now they just motor up them on a 50lb bike with garbage components and eat shit

Are you driving it on a public road?
Then yes, its the same as everything else. Its up to the local authorities to enforce the rules and fine importers for wrong information.

Are you not driving it on a public road?
Then no.

that's as much of a moped as op is an electric bicycle, i.e. not at all except possibly by pedantic technicality
good to see that manufacturers overpowering 2-wheelers of classes preferred by people of lesser handling skills is nothing new though

Mopeds as 49cc, 2.5 hp, and limited to 50 kmh.

Good 250cc motorcycles and scooters make 15 to 25 hp.

A ICE vehicle do not have the stated NM and HP numbers outside of the peak effectivity RPM.
Which skews the number even higher, since a ICE might only reach 30-40% of that outside of the ideal range. So its comparable to a very jacked 60-80HP motorbike, without any of the delays.

6-7 minutes of full throttle isn't bad.
Which is never needed because of how regen braking and cruising works. Meanwhile Tesla do 300kW with a 100kWh battery.

I mean power output of the battery.

Top numbers for lion batteries
Specific energy 265 W·h/kg.
Specific power: 1500 W/kg

So 1.75 kW.h is 1750/265=6.6kg.
6.6kg*1500 W/kg=9905W. Motor is 15000W.

Do you have autism?
15kW is 15kW. Or some 20 horses.
And 1,75 kW/h is 1,75 kW/h. Outputted via some random voltage(12, 24 or 48v), some random amperage, with some spesific Ohm value over the cables, with some effectivity loss in storage/output and engine.

Its either 18650 cells or 2170 cells.
Peak output isn't a meaningful value either. Turn of speed limiter of ebikes and you can quickly go 40km/h at 250w engine + 100w pedal.

Sure
But its not big losses compared to ICE.
Image only having a 12% less torque and HP when trying to take off in first gear. And then having constant good values until you reach some 12.000 RPM
And Tesla got better values than that.

Its very different from needing to reach 2100RPM or 3000RPM to reach claimed HP value. Where the entire first gear is a fucking dead end.

don't care.
Shitty meme unit.
Never lands anywhere near actual performance.
Gasoline is still in the 30% range of listed numbers.
>Spesific power
>It is defined as the power output by it divided by its mass
So HP/Ton? Or do you want to move the comma to HP/KG? Or perhaps kWh/Ton?
Or even better what about Nm/Kg?

Remember:
This reply chain started because some retard thinks a 1750w/h battery is small.

straight up bizzare you can buy that as a ebike. Most ebikes are basically mopeds and BBengines kill chains for breakfast, something needs to change, but Simon is a super douche, screw that guy

Why?
Watt / KG do not mean anything when the weight is the user, the frame, the engines and the battery.

Because battery has maximum specific capacity limiting it's power output per given weight.
