Assuming a rider and bike weighing combined 90kg on a 23mm wide tires, the contact patch would be roughly 2.82cm2 per tire, meaning a load of 15.96 kg/cm2 per tire. So in your opinion a single bicycle would cause almost 6.5 times more road damage than a Land Rover?

Weight is the greatest factor in determining road wear, you can't just look at the static load because vehicles move! Heavier vehicles cause higher dynamic loads when accelerating, decelerating and turning. It's also why road wear increases when speed increases: www.researchgate.net/profile/Mats...

Would love to see this in more places. Big pain point for me when cycling is trying to figure out the best route beforehand on openstreetmap, so I can spend most of the travel on trails or separated cycle lanes, instead sharing the road with cars

Hmm, don't know why but the end of the link was cut off, maybe this'll work - www.frandroid.com/survoltes/ve... , as for the website ads, I only get typical embedded ads, the only pop-up I get is for cookie preferences
On a roulé 6 mois avec un vélo électrique sans batterie : ça donne quoi un VAE à supercondensateurs ?
Alternative à la batterie lithium-ion, comme fonctionne et quelles sensations au quotidien pour la technologie des supercondensateurs sur un vélo électrique ? Voici notre récit sur le Pi-Pop.

Hooray it's not vapourware! 6 month test (in french) from: www.frandroid.com/survoltes/ve... - and website for the bike itself: pi-pop.fr
