I would be a bit worried that the extra weight compromises the structural integrity of the frame. 2kWh are heavy
Bikes typically have a weight rating. Mine has 150lbs of cargo capacity (is a cargo bike).
There's significantly more variation in weight between riders. If you're under the frame's weight limit, including battery, you're fine.
It does feel like this is such an untapped market. Think commuters, credit cart tourers, tourism around a spread out city. Something that is safer than a motorcycle and faster than a bike.
In Germany at least the routes are a lot prettier because they go through forests and villages. It's what got me to cycle more and ride my motorcycle less.
It's not safer than a motorcycle. Motorcycles have lights and signals and can accelerate away from danger. Plus the riders are generally covered head to toe in safety equipment, whereas nobody is ever going to wear leathers on a push bike.
Respect: that's a beautiful pack.

I'm a total sucker for ebikes and built my first ebike around 2006, powered by 40lbs of lead acid motorcycle batteries.

I recently outfitted a trailer with a large battery made for an efoil (my other obsession) where the non-battery components went bad, the company went out of business, and "Hey, this would make a bitchin' ebike battery.

Here's me cruising around the Oregon back country with said setup last summer: https://imgur.com/a/lmvJSBW

Wow. What is your total capacity and range with that setup?
In my city, travel habits and condition, I find I wish for more torque and lower speed. Every place I want to go has significant hills that the motor can't handle, and easing climbing hills is the main reason I want an ebike. My ebike's minimum speed for the motor is 15kph, which is ok by myself, but my family likes to go slower, so I have to go fully manual with them. When I look at ebike ads it feels like nobody else cares about these two areas of performance. When I talk to local ebike shops they are unprepared to talk about torque and minimum speed.
I fitted a Bafeng mid-drive motor to my city bike and it's fabulous for hills. Because the power goes through the existing drivechain you can get high torque simply by switching to first gear. No minimum speed, power kicks in after half a turn of the pedals. Coupled with hub gears you can change at rest it's a marvel.

Even at the European street legal limit of 250W it makes acceleration trivial.

Doesn't it help changing gears? You can even get sprockets changed to lower the gearing for more torque.
Huh, it's you bike have a hub motor? The thing inside the wheel?

Mine sits between the pedals. That means I can just go down in gear and the motor helps with going up the hill.

Exchanging torque and speed is like the only function of the gears on your bike.
Assuming it's a relatively cheap e-bike with a motor on the rear wheel (a hub motor), that's likely the motor being starved out of phase amps that create torque, rather than the motor being weak. Especially if it's large and heavy Direct Drive motor with no internal gearing. These need a strong controller (power supply) to feed them current, as voltage doesn't matter for torque.

But generally it's not the motor itself that's weak, it's just got a weak power supply (and potentially weak battery BMS. Some controllers tie phase amp output to battery amp input by some 2 to 2.5x multiplication ratio.)

Going from a generic KT 22A controller to a 35A KT will give over +50% torque. Up till the motor hits magnetic saturation, torque scales linearly with the amps. The thinnest kind of direct drive (27mm magnets) can hit 80-90nm too. Most of those are 30mm nowadays and can push 100nm tho.

On the geared hub motor side, the G062 (most 750w bikes use clones of it) can push 90nm before there's a risk of stripping nylon gears. Smaller ones like the G310 may strip gears earlier. These generally need less amps to produce torque than direct drive, so they work better with poor electrical systems.

Worth mentioning that wheel size matters for torque on hub motors. Larger wheels need more torque to climb (thrust). And also motor wattage doesn't mean much for torque (phase amps from the controller and gearing affect that even on bikes sold with the same wattage rating).

I also find the throttle gatekeeping or wattage gatekeeping a bit silly. Going 25kmh by throttle or peddling has no difference in how dangerous a cyclist is on the road. They should cap top speed and acceleration on throttles, but banning them outright unless someone is doing a minimum cycling motion on the pedals is a wrong regulatory approach and limits accessibility.

Throttles above 6kmh (walk assist) are banned across the whole of Europe. Judging by how heavily the Netherlands pushed for the EU-wide throttle ban, and putting my tin foil hat on, I can assume this was done as regulatory capture to ban Chinese ebikes from local stores, as they come with throttles and aren't usually capped at 25kmh on pedal assist. Netherlands produced ebikes are all pedal assist only, mid-drive, and have very poor batteries and electrical stuff for the (over 2x) price they're sold for. And now they have less competition. EU also has a 45% tariff on "e-bike part" imports...

I would also like a regulatory framework to register and insure a faster e-bike (as imo they should not cap wattage and cripple the hill climbing torque, only speed/acceleration) for adults. Right now you can only register one that has a license in EU. If you build your own, it can never be legal, even if you have a motorcycle license and want to insure it. This class of e-bike is impossible to drive legally right now.

L1-b class registration can technically do this, but it needs the bike to be registered in Europe. No e-bike has this. No manufacturers sell class L1-b e-bikes registered in the EU. Only some electric motorcycles afaik.

This is what gearing is for. Get an ebike with a mid-drive motor and some form of gearing -- a conventional derailleur, or an internally geared hub (Shimano makes a decent one, Rohloff makes a great one).
> My ebike's minimum speed for the motor is 15kph

That is a flaw in your ebike. Weird and dangerous.

Sort of a hijack, but it rides on the awesomeness that e-bikes can bring about. They truly are incredible if you have never gotten to ride one.

E-bikes with throttles should not be refereed to as e-bikes

E-peds, e-motos, electric motorycle, whatever. Just don't call them ebikes.

The problem is people (especially kids) getting what are essentially electric motorcycles, thinking they are ebikes, and then causing all sorts of chaos on roads and bike paths. This inevitably leads to the public hating "e-bikes" and the government passing totally confused laws about "e-bikes". This also leads to kids getting killed because mom and dad bought them an "e-bike" and let them loose on the roads with it.

Pedal assist ebikes are incredible, and really just turn weak cyclists into strong cyclists, while still providing exercise. It's a revolution for society, but we have to be careful to not totally fumble it with electric motorcycle death machines.

There's not much difference between a throttle and a sufficiently powerful pedal-assist. Switch to your top gear, and the torque-sensor will say "gee that's a steep hill, let me give you a boost" the moment you start pedalling.

Banning throttles just makes manufacturers install token pedals on the motorbikes.

I propose a new and improved e-bike classification scheme:

Class A: Bikes that can not go over 10mph via a throttle. And can’t go over 28mph with pedal assist. Or set the pedal assist limit at 20mph if you’re feeling especially conservative.

Class B-Class infinity: These aren’t considered bikes. Class A is the only class of e-bike.

The throttle isn't a problem, the top speed is. A throttle and pedal assist is nice because you can get started faster and more safely from a stop.

Kids riding out of spec motorcycles has always been illegal and always will be. The only problem is that they are a lot cheaper than they used to be.

I have a disability and can't pedal for many minutes or hours straight, but my electric scooter with a throttle is absolutely amazing for helping me get around areas that would otherwise require tons of walking (or pedaling). I guess I'm a demon that needs to be regulated out of existence?
A throttle is excellent on an e-bike especially for city riding. It is far easier to move at slow speeds by applying a small amount of throttle vs. trying to torque the pedals just the right amount, if behind someone or near pedestrians.

Many e-bikes don't have torque sensors and instead use a cheap rotation sensor so the motor engages almost randomly at certain points in pedal rotation when moving at slow speed.

Have you ever owned a motorcycle or are you making up dramatic terminology to prove a point?

The quick e-bikes aren’t motorcycles, not even close. Something in the Sur Ron class (30-40MPH) would be equivalent to a 50cc 2 stroke which you can ride with nothing more than a drivers license. Even then hopped up Talaria’s are a pit bike and don’t remotely approach a low end sports bike.

Fast e-bikes aren’t bicycles but they aren’t motorcycles. We already have a term for that, mopeds and scooters. Instead of banning everything the clear solution would be to treat them the same as mopeds (Have to be 18, wear a helmet, may or may not need a license) and call it a day without all the drama.

Disagree, the wattage of the motor is what's relevant. A 750 watt ebike with pedal assist has more potential to cause harm than a 250 watt "emoto" with a throttle.

The whole throttle vs pedal assist distinction makes way less sense than delineating the difference based on power.

The distinctions drawn here are particularly interesting in China.

Somewhere like Shanghai, you'll see ~70% of traffic in "bike" lanes are what appear to be electric mopeds.

But if you look closer, all of these mopeds technically have tiny attachment points for pedals. Government regulations allowed e-bikes to be driven unlicensed (but with a special green license plate, unlike the US!) and wherever bicycles are allowed. At the same time, the delivery industry and commuters wanted something stable, capable of carrying cargo/passengers. So the form factor adopted was that of mopeds, while vestigial pedal attachments were provided in order to pass as "e-bikes" under the regulatory criteria. Example. [0]

In practice, using pedals on these made for a clunky experience so they were not usually attached at all. The other main regulatory criterion was that these have to be limited to <= 25 km/h, unlike true mopeds/motorcycles. In practice, these speed limiters were also removed, setting up a cat-and-mouse game between police and riders.

The rule requiring the vestigial pedals was finally removed a few months ago, meaning that the ontology of "e-bikes" is pretty different in China now. [1] (Pedal-assist traditional bike frames also exist, but they share space with the larger mopeds in bike lanes and bike parking. True electric mopeds and motorcycles also exist, but they are effectively regulated out of existence in big cities.)

At the end of the day, top speeds are more determinant of whether different modes of transportation can coexist than pedals or form factor.

I think that size of battery would move it into requiring a motorcycle license here in Switzerland, just based on the size alone. And if it goes faster than 45km/h then definitely.

I have my motorcycle license and have been considering getting something that I can ride all day. Only problem is that if it's classified as a motorcycle license I don't think I can take it in the train like a bike if I run out of juice far away.

While I don’t think anyone should be allowed to take a 2150Wh home made battery on a train, I’m not sure why battery capacity should affect classification. Limiting power delivery makes much more sense.

Quite common for Bosch powered cargo bikes to allow fitting two 800Wh batteries and you can always carry spares. They’re just horribly expensive.

I’m very glad my US spec e-bike is 28mph/45kmph rather than 15mph/25kmph limited as I feel much more comfortable taking the lane closer to car speeds on residential roads even if I rarely go above 20mph.

The article mentions using Trespa, which I had to look up. It's a type of cladding that is fire resistant but is also not metal. It's a laminate type. The author is in the Netherlands, the infrastructure there must be really good to be able to ride 160km on an e bike between cities.
eBikes are such a game changer. I do most of our family of four's grocery shopping with ours.

Because of the assist, I find myself more comfortable in a wider range of weather conditions:

* If it's hot, I use more assist and there's an instant cooling effect. Much better than climbing into a hot car.

* If it's cold, I dress up to be warm outside and if I start to warm up on the ride, I use more assist. I don't have to try and balance staying warm and not getting sweaty.

* Same thing if it's wet out: I can wear heavier waterproof gear and not get sweaty.

I think we have different grocery habits.

Food, beer, and cat litter would be too heavy for a bike.

I bought an entry level ebike and the range is about 100km on lowest power on flat land, and of course it increases if you drive above 25 km/h.

I don't know what the difference is with what op has, but for me it's no extra issue to drive above the top speed. It's a gradient transition.

I use mine daily and charge it every two or three weeks.

The highend ebikes are actually worse at this style of riding with minimal assist, since they are 30 kg behemoths which ride like shit without plenty of motor power.
Very cool. Thanks for sharing. I have an ebike myself and have considered just strapping extra battery packs to the frame so that I can just swap when required. In the end, I mostly take shorter trips (I’ve had it since Dec and my odo only reads three figures).

Speaking of R&M, I have wanted to get one of their bikes that has the child container area in the front. I saw one guy with one and it looked pretty awesome. A large bike like that would benefit from some larger battery pack. And those have a flat area in front on the frame where you can host a few parallel to the floor (hard in a normal bike frame).

One annoying constraint is that it’s hard to find a place here in America where people won’t tacitly kill children. As more people here become online only child-free characters driving large EVs they don’t think too much about killing children and will only delay someone’s license for a couple of years for doing so.

The hard problem seems to be other people.

I was disappointed to discover that my e-bike could not charge and power the drivetrain at the same time. Visions of range extending backpacks were dashed in an instant.
> Speaking of R&M, I have wanted to get one of their bikes that has the child container area in the front. I saw one guy with one and it looked pretty awesome. A large bike like that would benefit from some larger battery pack.

I'm planning to buy one of these (Load 60 or 75). I think they can mount two battery packs (2x 800Wh = 1600Wh) on the frame.

If I'd want more range, I'd go with an extra battery in a backpack.
... put your (e)bike on a train, that's where the range come from.

Very cool experimentation but in term of making the practice sustainable best to rely on the infrastructure. It's a bit like in sports having to use the big muscles, e.g. you climb with your legs, not with your fingers no matter what super strength grip you have.

The aerodynamic situation of a bicycle is so disadvantageous that the easiest way to get a long range e-bike is to simply ride more slowly. People internalize beliefs about energy-range ratios from electric cars, but they don't translate well to bicycles.
It is kind of a shame that recumbent bikes are expensive and bike nerd coded. A recumbent e-bike with an aeroshell would be fantastically efficient and useful in so many situations, but if you tried to buy one today it is going to cost as much as a car and have everybody else sneering at you.
The exact same thing applies to electric cars, though -- going slower significantly increases your range.
What about a velomobile? They're quite expensive because they're boutique items right now, but it seems like using the pedelec classification for something with significantly better aerodynamics would make for an interesting electric vehicle.
It's weird that these restrictions apply: 25km/h, 55km range? The Evolve Carbon skateboard tops out at 50km/h, and 80km range. Granted, you have to be a little bit crazy to ride that fast on a skateboard, and having owned an earlier version, I guarantee it's not pleasant riding that far on one. But people do it. Someone must be putting out faster/longer distance bikes that don't look like/ride like mopeds.

Okay, a quick google and this seems somewhat moped-ish but 200 mile range, 28mph top speed: https://aniioki.com/products/aniioki-aq177-pro-max-electric-...

Crazy price, but a real bike with 300 mile range and 36mph top speed: https://shop.optibike.com/shop/r22-everest/

Ebikes cannot go faster than 25 kph in the Netherlands, where the author lives. Also they cannot provide power assist without pedalling.
The Europeans love a nanny state and ebike licensing is no exception.
That skateboard is legally a toy and you cannot ride it on the street. You will be on your own if you cause an accident with that thing. Insurance will nope right out; chances are you will serve jail time if anyone is seriously harmed.
Man: “How much power that thing got?”

You: “Yes.”

Right after the pandemic of 2020, I joined an “outside squad” of OneWheel enthusiasts, PEV daredevils, and E-bike low riders. We would ride around the city in 70 man packs. It was the most fun I’ve had as a grown up. :) Even broke my olecranon in a nose dive but rode my wheel out of the hospital. Best money spent.

I know a guy who tried doing something like this and burnt his house down. One of the batteries exploded and took the others with it.
I think of e-bikes as a kind of "electric horse."

* Goes about as fast as a horse

* Goes about the same distance as a horse

* Sitting on a saddle like a horse

* Out in the weather like a horse

* But no feed or vet bills

* No need for lots of land or infrastructure

* Little ongoing maintenance

* Little skill needed to ride :-)

> My first e-bike, a pretty crappy one but enough to get my appetite whetted had a 500 Wh battery, enough for a 55 km trip one-way, and it would be dead on arrival, range anxiety to the max.

What? 55km with a 500Wh battery? Was he not pedaling at all? Why does he even have range anxiety on an ebike? You can just pedal if the battery is low.

That’s a fantastic build, I only wish e-bike manufacturers would offer similarly spec’s bikes, a days ride is very rarely 30 km, so 200 min or more like 200 km range would be a bike worth investing in. I feel similarly about electric cars too, charging mud route or at destinations is rarely possible so 300 miles or greater are the only vehicle ranges I see as remotely practical. ( yes, I cycle in km and drive in miles , weird maybe) Oh yes an edit - speed, who rides so slowly, those ebike speed restrictions are crazy low.

So, this got posted again I see. A few years later: the pack is still going strong and has not - so far - shown any signs of wear. I've put close to 15000 Km on it now and there is no degradation worth mentioning, though I suspect that if I do a precise capacity measurement that it would definitely show some reduced capacity.

The really neat thing is that at the end of a long ride the cell groups still track to within 2 mV of each other, which is a strong sign that all cell groups are discharging equally fast and that there are no cells or welds that are causing problems. Of course with 17P the cells are only mildly exercised compared to what they would be going through in a regular pack.
