Fantastic ebike lock

I go to office 3 times a week and I use my
Aventon pace 5000.3. I could not ask for more for Christmas.
Kryptonite KryptoLok U-Lock is safe and secure. I recommend it a million times.
Thanks aventon.

Thank you for the feedback!

Great Lock

Not only can the lock be use for one bike, we have used the lock to safely lock three bikes together. Good design and feel secure when having to leave bikes unattended.

Thank you for taking the time to leave a review. We appreciate your feedback!

Promotional product

I bought a new ebike for my husband back in October.. during that time there was a promotion that he got a free helmet and a crypto lock. We received both but have sent the helmet back about a month ago due to it being too small. I have reached out several times to request a replacement for that helmet in a large and have not had any luck getting a response. Very disappointed. Stephanie Coleman

Sorry to hear that! Our returns will be getting intouch with you if they haven't already. Thank you for your patience with us during this time.
