Heard from shop owner in Amsterdam that this event took place recently.
40 years of Netherlands Human Powered Vehicle Association. Some may know of it via ligfiets.net. Often reposted and interacted with City Cycling in past.
Lots of talks about historic development of HPVs in Dutch of course! (Late) Mike Burrows of course gets a mention.
But skip into the 8 min mark and check out the assorted pedal power. Lots of Quest models of course @arellcat !
Filming done from Flevo GoLow e-cargo quad. They are one of the most innovative specialist bike companies in NL and interesting (to me!) that both they and Optima diversified into e-cargo when the recliner scene hit a sales limit.
Ride starts at 8 minutes in. Admire the infra!
