Wouldn’t mind travelling around the state on my ebike. Happy to buy a new one if there is one that’s much better.

1. What’s the best electric bike capable of at least 80kmh, ideally with pedals?
2. Why are these fuckers so hard to ride purely with the pedals and 0 motor assist? Can I make it easier without removing the motor?

Where are you going to charge it?
Those bikes typically have sub-100km range

You're going to have to diy your own sui-cycle if you want a pedal assist and those speeds.

IDK might have something to do with all that extra weight compared to a regular bike. Still waiting for some peer-reviewed studies on that to confirm.

You don't need a study, I recently lost 20kg and the 25kg ebike was definitively harder to ride than my 8kg road bike when I was fat.

I can't answer question #1 since I built my own, but for #2 there's various reasons. Weight is a factor, motor resistance, and possibly the gear ratios on the bike meant for motored power rather than human power. A mid-drive ebike should be easier to pedal than a direct drive hub motor, not to say that you still won't feel a little resistance.

Give me the details of your kit. What’s the top speed?

80km/h is an electric motorcycle, not an ebike. Stealth bombers, surrons and so on do not come with that sort of top speed and pedals. Maybe you could get a cyclone mid drive or xyc with tall gearing to do it, but that is an expert level project. Nothing with pedals is build to be stable at those speeds.

go down to about 60. Put that xyc or cyclone on a good full suspension bike, and you will be halfway there, except they take a lot of battery, so at any reasonable weight you are still only riding around town, not travelling around the state.

they aren't that hard to pedal. Just needs getting used to. When I get on a regular bike after using electric for a while it feels wrong.

They
>weigh a gajillion lbs
>massive who the fuck cares about rolling resistance tires
>low saddle height(generally)
>massive bars/no aero
>efficieny loss in motor to rear wheel
>full suspension so your pedal inputs are bouncy and not 100% efficiencient
Also
>being used to 20+mph with low effort
makes it seem so easy. Most road bikers are going pretty good at 20+mph, let alone 30mph.
I know your picture might be called an e-bike, but it really is blurring the lines between e-bike and e-motorcycle.

Sorry chud but anecdotal evidence doesn't count. Until the science is settle please refrain from posting wild assumptions.

I think in a few more years as battery tech continues to improve, and more and more consumers turn to e-bikes, these are going to be a huge mode of transportation. Not quite there yet, but on the verge.

I know it doesn't fit your criteria, but Voltbike is probably one of the best e-bike manufacturers in North America in terms of quality-to-price. They are super well built and need very little maintenance. I've taken mine pretty well the entire length of Vancouver Island and racked up thousands of klicks, and it's only needed oil. However, because they're made in Coquitlam, they aren't capable of exceeding the Canadian speed limit of 34 km.

It's the Hub motor working as an inefficient ball bearing.

This is something you can test. When you add a second hub motor at the front wheel (even while it's unplugged and unpowered) it will reduce your range significantly.

Seriously, dude.

You only need pedals to make the Police Officers think you're one of those faggots needing pedal assist.
Thus it has to have lots of power (let's say 1000W) because mountains and steep roads, and a stealth speed limiter button (because going 20mph is usually enough for self-snitching).
That case could be home to 100× 21700 5Ah cells, totaling more than 1800 watt/hours in ~15lbs, that would be 50-60 miles at best, you will run out of juice in three hours.
So you need 300-400 cells (say 7200 watt/hours), and some way to charge them in some 6 hours ("less than a night"), so the charger included with the bike should be no less than 1200 watts.
Theoretically feasible, practically... it's clearly not anymore an e-bike, even less a stealth one. You'd end up with something like the BMW CE04. You'd add a full fledged inverter, possibly a microwave oven (so that you don't need to light a fire to make a coffee or dinner) and a large foldable solar panel (sorry, won't give you a thousand watts every hour).
