Vigurvänt pedals are compatible with 9/16” threaded cranks. Generally it means 100% of bicycles, but there is also less used 1/2” thread standard that is used on bicycles with so called one-piece cranks. It’s easy to check which ones your bicycle has if you compare the crank arms.
1/2” thread owners have still one solution, please search “pedal thread adaptors” for details.

After 100 meters of riding, another question popped up: why the hell aren’t the pedals wider, so the passenger can keep the feet somewhere and at the same time “lend a leg” to the sweating friend behind the handlebars?
This exact thing happened to Kristjan Holm and Kaspar Jancis one fateful morning. The first sketch was drawn soon after!
Later the same day – bizarre! – it’s not possible to buy this kind of pedals from eBay or anywhere else… Well, then it’s just the time for a small brainstorming!

Looks like a cyber fly!
The first test! To be continued…
