Yes. This is the way. Thank you, Dutch government.

If somebody feels like wheezing an almost completely silent 200kg projectile, godspeed. But please gtfo from the urban bike paths, if at all possible.

This bike has the added benefit of being theft resistant - on the basis that it's too heavy for one person to lift. Seriously though, what does it weigh?

With a typical sized Dutch man, stopping from full speed is going to be a real test of the brakes...

For the same reason I don't like scooters on bike paths, I wouldn't want this sharing a bike path with me. When heavy fast vehicles and regular bikes collide, the regular biker usually suffers more.

About 35 to 36 Kg. Bike + rider is 105K, which is actually not that bad. Your typical parent+bike+two kids is a lot heavier, I've had my 'daddy bike' up to well over 130 Kg before one of the kids was old enough to ride by themselves.

Full speed to stop is pretty good too, I did a couple of e-brakes to see how the change of weight and COG affected the bike. Stopping distance is a bit longer, it doesn't kick out when braking hard in a corner more than it did before, and - not surprisingly ;) - it transfers a bit more weight to the front when you hit the brakes hard.

But compared to a scooter it is much lighter and compared to a normal e-bike it is only 5 Kg heavier (29 vs 35 Kg).

It weighs half that, including me, and the average speed over a longer trip is about 33 to 35 Kph. In cities you ride just as fast as the rest of the bike traffic, there isn't any point in trying to go faster, and top speed is rarely achieved, you'd need a 100% full battery and a rider in very good condition. More usual you'll be around 35 to 38 kph in open country where there is very little other traffic.

My 'commute' is 64 km, it takes me two hours on the dot door-to-door.

That is impressively light. My opafiets is 30kg.

All aluminum bike really helps, as well as a relatively small frame size. But still, the battery makes it noticeably heavier.

Bare weight of the cell is 50g. With 170 cells that is is 8.5kg. Still considerably lighter than cargo e-bikes.

And 40 of those cells can be discounted because they were also present in the old pack.

It’s worth saying that it’s not to hard to train up to being able to do 100-200km rides with no electronic assist. At such distance, the weight saving is probably outweighing the battery and you can use the space in the frame can be used for luggage such as extra clothing. At longer distances the ride limiting factor is comfort, not stamina / endurance - here the Ebike adds nothing

We have a pretty good network of fire roads in the southern Los Padres National Forest. Several times recently I have seen hunters and campers using E-Bikes to extend their range into the forest. From what I can tell they use a cargo trailer for gear as well as extra batteries. It will be interesting to see what other uses being find for E-Bikes as ranges increase.

An added benefit for hunters is that deer aren't afraid of the sound of bikes. Similar to cars, they just don't care. It's much easier to approach a deer on bike than on foot.
