4.9/5.0 average rating

"The ease of mounting on the board without extra cables or battery packs and the control with the remote on the paddle makes this electric fin particularly innovative and simple."

Willi hunter

“Die Jaykay Elektro Finne ist wirklich sehr durchdacht. Alles ist in der Finne untergebracht, keine störenden Kabel, kein schwerer Batteriekasten – einfach montieren und los geht’s."

Douglas Battles

The quality is simply impressive! The power of the fin really surprised me. Es is a lot of fun to ride!
