helmes
there are contrary opinions about helmets and also studies contrary opinions avilable. The best summary of these controversial ideas is available on https://www.cyclehelmets.org/
Let’s look at some facts, which are independent of the personal opinion:
- news reports and media center around this question, especially if riders experience severe accidents (see accident reports)
- most countries don’t have legal obligation for cyclists to wear helmets
- The pro-helmet reasoning is summarized here:
“The head is a sensitive part of the body. Even an impact at a speed of ten kilometers per hour can lead to severe brain damage. Above 16 km/h, the head usually cannot survive a collision without injury. Bicycle helmets significantly reduce this risk. Studies on accident victims who have collided with a motor vehicle show this: People who do not wear helmets are nine times more likely to suffer serious head injuries than those who do.”

cornering
Most velomobiles don’t offer a ‘leaning into corners’ in difference to upright bikes. (Velotilt concept is an exception).
3-wheel velomobiles have the tipping axis is very close to the center of gravity, which leads to a threat of tipping over.
- The higher the speed,
- the tighter the corner,
- the higher the tipping threat
