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.

EuroVelo will blow your mind.

If I'd want more range, I'd go with an extra battery in a backpack.

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.

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.

It’s only safer than a motorcycle if you have bike friendly infrastructure.

The fact they are kind of slow and you can take them on trains helps compared with motorcycles.

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.

I would be a bit worried that the extra weight compromises the structural integrity of the frame. 2kWh are heavy

high quality heavy 18650s weigh about 2 oz. 190 of them would weigh about 24 lbs. Throw in another 6-10 lbs for bms, wiring, casing and errata and it's not that bad.

I would be more worried charging that huge home built battery pack. I'm sure OP knows what he's doing, but I wouldn't want to bet my house on it.

Bikes typically have a weight rating. Mine has 150lbs of cargo capacity (is a cargo bike).

I don't know if this figures into the engineering formulas, but an e-bike needs to be stronger due to the higher speeds and power levels. On a human powered bike, if you're hauling 150 pounds, you're probably going pretty slow.

My friends who have e-bikes go through a lot more "consumable" parts such as chains, tires, brakes, cogs, and bearings.

That's why at https://infinite-battery.com we designed a fireproof and waterproof casing for our repairable batteries

... 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.

Fucking people pushing their ebikes into already crowded trains! You wanted to cycle, go cycle then; don't pester us regulars with your 30kg dirtmachine.

99% of the time it's food delivery workers who have to live in the outer edges of the city while all the orders are in the inner city.

The solution to this problem is to run enough trains that they aren't so crowded a bike wouldn't fit. These people are paying for tickets so their usage should be funding the running of more services.

Where exactly is this train that I should put my e-bike on?

Not everyone lives near mass transit nor in a city

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.

They're also a great way to get really badly hurt.

The title should say (2021). Great article.

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.
