Great customer service

I had ordered a spare battery for my sport cool , before sending it they verified with me by pictures the bike I have and told me the battery I had ordered was incorrect. Thank you Ecotric team for contacting me before sending!
Got the battery quickly afterwards and fit like a glove.

Replacing battery for EBike.

I could not be any happier with this warranty service. Even though I had to source the battery myself everything went smooth. I strongly recommend Square Trade warrantee service.

I love riding my Vortex. Having a spare battery with me allows me to ride all day long. The battery performs excellent in rain and cold weather. Enjoy!
