Good news! Looks like a different company took over Schlumpf Drive in April 2024. Can’t post the link here for Spam protection, but search for Kwiggle Bike GmbH or Drive-Mobility[dot]com/en2) The company behind the Schlumpf Drive products appears to be dead. They haven't answered any emails from their distributors around the world, nor have they shipped any open orders, in about 9 months. It's sad because the Schlumpf products are FANTASTIC. I absolutely love my Mountain Drive. Sadly, now when it eventually needs serviced, it'll become a paperweight due lack of parts.
I have but it's a traffic light instead of a stop sign that I have a great view of from my porch. The majority of bicyclists do not obey the lights. Jumping off the road to the pedestrian crossing and going through that section (while the pedestrian light is "don't cross") seems to be the most favored method of avoiding stopping at all costs. But as I see it, they'll only kill/injure themselves, the cars will be fine.Have you done this? Assuming that you're in a region where bicyclists are required by law to stop at stop signs (in several regions they are not), the results should be roughly equal according to the studies I've seen. (Which I'm pretty sure means close to 0% for both in my region... But that's a different story.)
I think close to parity for following laws for bicycles doesn't look good for cars. There is no formal training or certification for cyclists, so would it be any surprise that they are less likely to follow laws? For example it is personally even difficult to find out when and where you are allowed to ride on sidewalks and it changes on a town to town basis around here.Have you done this?

People regularly hit over 70 km/h / 45 MPH downhill on normal diamond frame bicycles. I hit over 33 MPH / 53 km/h on my work commute this morning on a slow commuter bicycle, and I probably wasn't even pedaling. I certainly wasn't trying to go fast. You just have to learn to manage risk, because it's never going to be as safe in a crash (to the user) as the smallest, lightest car. It's a lot safer for those outside of it, though.With possible speed over 40 km/hour, what is the regulations on crash-worthyness [sic] of the shell? None, equal to motorcycles, or equal to a small car?
Edit: Regardless of the motive power, Internal combustion engine, electric motor, or pedal power, I prefer there is the same safety requirement whenever a vehicle exceeds a certain speed.
Have you done this in a systematized manner, rather than just "I see this lots"? Because you are absolutely going to get confirmation and selection biases based on observations.I have but it's a traffic light instead of a stop sign that I have a great view of from my porch.

Front impact -> DeadAFAIK we don't even crash test motorcycles that can do over 200 kph.
Some velomobile videos
My observations are absolutely anecdotal. I've personally witnessed 3 car-bike accidents. And all 3 were 100% the bicyclist's fault. I know there are responsible bicyclists out there, I do see them. Maybe my area does have a terrible bike culture (college town) but if you cross in the pedestrian walk, unless I'm badly misinformed, you are expected to obey the walk/don't walk lights and if in the road the traffic lights.I can't argue against what you say happens next to your porch of course (unless you happen to be my neighbor). However, I believe your observations are anecdotal and cannot be applied to general groups. Perhaps the bicycling culture in your region is particularly egregious. Perhaps your observations are biased. We may never know. In the meantime I will trust what little data is out there.

As both a trike rider and someone in the industry, I have two big things to point out:
1) You can try several brands of velomobiles, including Bülk, at CycleCon (formerly Recumbent CycleCon) in Xenia Ohio each fall. It's open to the public and completely free.
2) The company behind the Schlumpf Drive products appears to be dead. They haven't answered any emails from their distributors around the world, nor have they shipped any open orders, in about 9 months. It's sad because the Schlumpf products are FANTASTIC.

Actually, I would argue that bicyclists are more prone to rule breaking. Go to any intersection with a stop sign and count what percentage of cars and bikes actually come to a complete stop. I'll wait for the results.
That's the thing about anecdote - it really doesn't tell you anything. For instance, I've been involved in one (very, very, minor) car/bike accident. I was on the bike, and I'm comfortable saying it was 100% the car driver's fault because I was on the sidewalk at the time. Does that mean anything relevant to policy? No.My observations are absolutely anecdotal. I've personally witnessed 3 car-bike accidents. And all 3 were 100% the bicyclist's fault.

In my state, Michigan, they are required to stop at stop signs and red lights. Maybe half of them actually have lights. Can't even remember the last time I saw a bicyclist use hand/arm signals. Maybe they all moved here from your state?In my state I don’t need to come to a complete stop at stop signs or red lights. I need to yield to the right-of-way and if it’s clear I can proceed. The laws for automobiles aren’t always the same for laws for bicycles.

From the state website:
- Bicyclists are required to slow down and come to a complete stop at stop signs and traffic devices signaling red.
- Some traffic signals only work when they detect a vehicle at the intersection. Dead red laws that allow cyclists to proceed through a red light, after they are stopped at an intersection for a complete light cycle and/or when there are malfunctioning signals.
- At night, a bicycle must be equipped with a front white light visible from 500 feet away and a rear red reflector visible from 100 to 600 feet away. Additionally, a rear red lamp, visible from 500 feet, may be used.
- Bicyclists must use hand/arm signals when turning and stopping.
Come to the Netherlands sometime.On topic (sorry guys), as a life long "upright" bicyclist I'm just blown away by the efficiency of velomobiles, even if it all makes sense on paper. The efficiency of upright bicycling is so deeply embedded in my body and brain that it's almost hard to come to terms with these numbers. It's really impressive.
What I'd love to see in my utopian vision of the world is medium to long range bike commuter highways where there's a fast lane for velomobiles and speed phantoms, and a slow lane for everyone else. It doesn't even really have to be painted, it could even work as an unwritten rule. Then people could commute long distance at high speeds using nothing but their own power, without having to worry about cars and without having to adjust to slower traffic all the time. At the speeds these things can reach we might need more stringent safety measures though to make sure no one gets hit at 60mph...
The best setup I can see for this is for a rear hub motor with a relatively high torque gearing. This is pretty mechanically simple. (just need a battery, a hub wheel, controller, and battery. However with European regulations, the 250KW assist limit generally would push the system to a more complex , shared drivetrain configuration. Since most of these velomobiles seem to be EU imports, I don't see it being a huge thing.I know it might be antithetic, but I'm wondering whether anyone has started creating e-velomobiles... seems to me like that would be a solution to the uphill issue; I know I sure wouldn't want to ride one of these on the switch from down/flat to uphill in traffic, just because I'd be switching rapidly from ~40km/h to 5km/h while the traffic is still moving at 50 or 60 (or more realistically, a mix of 60 and 80). To someone going 80, I'd be switching from an object that can't hop sideways out of their way and is going half their speed, to something that is effectively stationary and can't hop sideways out of their way, in pretty short order.
Interesting thing here is that since wind resistance isn't that big a thing on a velomobile, assuming you've got momentum, a battery assist could probably be fairly low power on the climb, and the added mass would only affect acceleration, not traveling energy, on the flat.The best setup I can see for this is for a rear hub motor with a relatively high torque gearing.

Your best bet would be to buy an plain one and add an aftermarket hub motor. (At least in North America). Since the higher power limit (750Watt in the US) allows for more torque. Even then You would have to be very careful not to overheat your motor on a long climb. There is also the issue where adding the motor will probably add some extra drag to the overall system, reducing speed on the flat. How acceptable that is really depends on your environment.
Can Confirm. I ride one of these things in Los Angeles.But people really notice recumbents & velomobiles because they's so different. More common bikes may as well be invisible by comparison, nothing about them grabs attention.

I rode a Canondale recumbent through Hollywood and in the Valley during rush hour, and at times people would get too close for comfort, and that's on a bike that has my head only a foot lower than a regular bike - I'm eye level with regular cars.
I got a Velomobile for an ultra long commute and electrified it so I could go up mountains (not hills, mountains), and people give me a ton of space in this thing! Even though I'm lower to the ground, and eye level with the super fancy hyper cars that zip around town.
Best bike rides I've ever had regarding personal safety and people interactions.
I've added a Bafang BBSHD to mine, and I use it for climbing the mountain to get home after my rides.Okay, so velo-e-bikes...
Just to focus on this one, specifically. A law mandating the use of hand/arm signals seems like a good idea on the surface, but it's deeply problematic for a cyclist. If somebody does something stupid - overtaking me and then doing an immediate turn, cutting me off, for example - I'm not going to take my right hand off the brake to signal that I'm stopping. I'm going to squeeze those brake levers like my life depends on it, because it pretty much does. Under a law like that, I've immediately broken the law, despite my action being the safest/best/least bad option in the circumstances.Bicyclists must use hand/arm signals when turning and stopping.
How much storage are you looking for?An e-version of one of these with a tiny bit more storage area would be perfect for small errands.
How many of those drivers were speeding shortly before getting to the light?I have but it's a traffic light instead of a stop sign that I have a great view of from my porch.

It is hot in there in summer.I suspect that the biggest design issue will be to ensure adequate cooling without dramatically increasing drag. This reminds me of the initial designs for a ducted fan within the propeller spinner of the Focke Wolf FW190A. It proved to be inadequate for engine cooling. After all, the Volomobile and the FW190A both have air cooled engines.
Speaking with about 20,000 miles of enclosed bike riding, a velomobile feels more like a sports car in its handling than a bicycle.The Velomobile is a fantastic idea that is likely not for me. For me, a big part of the pleasure of cycling is experiencing the outdoors; the rushing wind, the sights, the sounds, the smells. I have my bike set up for an upright riding posture and I take it easy. I don't care if I'm being inefficient. I'm enjoying myself.
Close me into a shell and a big part of why cycling is enjoyable disappears. That open air feeling is sacrificed on the altar of practicality, likely for the sake of commuting or something? If I wanted to be enclosed in a box I'd drive a car.![]()
Speaking as a cyclist myself, I see far more poor judgement calls from motorists than I do from cyclists - including one incident where I nearly won the door prize (as the saying goes when a driver opens their door to get out without looking; fortunately, I saw it coming and had room to move over to dodge the door.)
I most emphatically am not saying drivers don't also do illegal, dangerous stuff in intersections. They do, way too often, and it clearly creates a very real threat to pedestrians and other motorists when they do. But I never see drivers blow through a light after the traffic column has stopped (most likely because they generally can't - if the car in front of them is obeying the light or stop sign, they pretty much have to follow to suit), and I do see it, not infrequently, with bicyclists. It creates a hazard with any bicycle, but particularly so for recumbents.
(And this is not about me wanting bicycles off the street. I don't feel that way at all. I am merely reporting what I observe, and why it concerns me.)
They are OK, stable due to 3 wheels.Question for owners, how are they in crosswinds?
Building a DIY-velomobile from scratch, looks a lot easier than done. First, you need to build a proper plug (positive model) to build the molds. The velomobile body requires at least three molds (left side, right side, bottom) and a at least an other three or four molds for the wheel wells. Its a considerable amount of skill, time and money involved to build a functioning velomobile.It's not THAT dangerous, although it does require proper precautions. And you can buy a LOT of fiberglass for $8,000. You can buy a lot of fiberglass for $200. Doing it in your backyard instead of a garage takes care of the space and smell problem.
It really depends on the velomobile model and your vehicle speed. They are fairly light vehicles with a huge side profile, so any cross wind, or the strong wind gusts from oncoming trucks, are pretty noticeable. In the more stable models, its just an "oops", but the less stable models can get blown across half the lane before you catch them.Question for owners, how are they in crosswinds?
True.Maybe not the best vélomobile advocacy videos when the guy is going 20 km/h over the posted speed limit quite a few times. But certainly impressive...

Left arm is used for all signals on a bike (at least in North America, might be different in right-hand-drive countries, but this law you're commenting on is from Michigan). And signals aren't required in emergencies (do you see anybody in cars hitting the turn signal before swerving around an obstacle in the road or hitting the hazard lights before slamming on the brakes?). Signals are for advance warning to let people know what you are planning to do soon so they can prepare for your actions.Just to focus on this one, specifically.

You do the head check, then you signal, then you check again, then you move. Same as in a car: you signal before you move, not after you start to move. Are you really travelling so fast without paying attention to where you are that you can't spare an extra second or two to signal ahead of time? "Oh shit, that's my turn, sorry!" doesn't really cut it.Turning is also problematic; if I need to move over to the right (equivalent to the left in the USA) to make a right turn, I'm doing a head check to make sure it's safe to do so. I am not taking one of my hands off the handlebars to signal what I'm doing while I'm in a position that compromises my ability to keep the bike moving in a straight line - even if the law says that I'm supposed to. (On a side note, this scenario is one I generally try to avoid. Fortunately, it's legal for a cyclist to do a hook turn at all intersections in Victoria, so it's relatively rare that this situation crops up.)
I'm pretty sure for cycles you can you what ever hand you want. Left arm is for cars (assuming your arm isn't long enough to pass through the passenger window. However most drivers I know don't encounter them enough for hand signals to be effective. You can try it out with your friends (who don't cycle), randomly ask them to identify a stop hand signal. If they take longer then 3 secs to figure it out consider it a failure (in real life, if other drivers take longer than 3 secs to identify what you mean, then it is too late to matter). I have seen cases where a turn signal is misinterpreted as an invitation to pass for potentially serious consequences and I don't see anyone faulting the driver for failure to heed the hand signal. I have a hard enough time for drivers to see me on the road at all, expecting them to see me pointing my hand and understand what I mean is a bit of a joke. We barely expect drivers to use their turn indicators properly.Left arm is used for all signals on a bike (at least in North America, might be different in right-hand-drive countries, but this law you're commenting on is from Michigan).
