I am surprised velomobiles are never mentioned: they are much faster than traditional bicycles, have some protection from the weather and can be electric assisted too: https://en.wikipedia.org/wiki/Velomobile

By and by, enough cars will be equipped with enough driver assist that heavy cars that must be crashworthy at relatively high speeds will no longer be needed, much in the way active safety makes light high speed rail carriages possible. Then lightweight vehicles can come in to wider use. Imagine how road capacity would be increased by something like a lightweight one-seat series hybrid "bike" with an enclosing fairing. A lot of communities could be done in vehicles weighing 5-10% the weight of a car.

Awesome project Jacques! I saw a comment of yours on an article a day or two ago and was hoping to see this pop up soon. I've found the most difficult thing about riding an e-bike is the other motorists have no idea how to react to you. You're not really a regular bicycle anymore due to your speed, but you're also not a motorcycle that deserves its own lane. I have at least one car turn in front of me almost every tr…

> You're not really a regular bicycle anymore due to your speed

I don't understand, ebikes are regulated and the assistance will top at 25kmh in most EU countries, which is a very average speed for a bike without assistance.

Unless you're talking about speed bikes, that can ride faster but are regulated like a motorcycle with license plate and can't ride on cycle paths. So it's just an electric motorcycle that looks like a bicycle.

Electric moped that works like a bicycle.

It's very much less convenient than a bicycle since it's bigger, less maneuverable, harder to get in/out and harder to "park".

Also, when commuting you don't need "fast". A bicycle or a regulated ebike are sufficient enough given the constraints you will encounter (lights, stops...). What makes using (e)bike to commute awesome is not the speed per se, it's the reliability. You won't be stuck (= taking part) in traffic, so if on Monday you take 30 minutes to go to work, it will be the same each day of the week. No need to rush to +30kmh between lights.

As a cyclist I tend not to care so much about all the mistakes other people do. Realistically it's a very small percentage of people that are new in traffic, the problem is that you usually only see the mistakes people do. You will never see that cylist who changed their pace 20s ago to avoid you. What has been shown is that people who travel by many different modes; cylists, pedestrian, motorcycle, car, bus etc, are…

I agree and provide examples. As a cyclist I know that a road bike is faster than a car in a roundabout so when I drive my car I don't overtake bikes right before roundabouts: either they'll try to overtake me right where the road gets narrower (unsafe) or have to slow down behind me (and they don't have an engine). So I slow down a little and overtake them after the roundabout. Same thing when approaching a red traf…

The second (to walk on the left) is actually the recommended way to walk when there is no footpath because you see the oncoming traffic and they see you. Which is much better than being hit in the back by something you never saw coming.

Awesome! What speed does eco mode mean? A 500km range is pretty impressive, possibly also longer than it would be comfortable to sit on a bike without needing to sleep!

The speed doesn't really change, it's just that you have to work that much harder to achieve it. In ECO mode I'd say you are going to get tired about twice as fast as you would at max assist.

The 500 km range in eco mode is something I never expect to even go near though it might be fun to once ride around IJsselmeer or so on a single charge.

Yes, this is definitely a good point. There is an arms race like effect at work here, if you could de-escalate that lighter vehicles would be much better.

OP was referring to pedestrian/bike paths. I believe everyone should stay on the right. I agree, with car traffic, pedestrians should be on the left.

You're in the realm of replacing original parts with the new battery mod. Why not replace the Bosch motor controller with any available motor controller that lets you configure your throttle inputs however you want?

Because that would invalidate the type approval and that in turn would invalidate my insurance.

The insurance is OK with a home made battery? And there's no concern for public workers if some unidentified custom battery catches on fire for example?

I've never seen a thumb throttle burn down someones house. Alibaba batteries though? https://endless-sphere.com/forums/viewtopic.php?t=87975
