You may have noticed that the shipping date for some models is currently listed as several months away.
While we understand that this is a long time to wait, we wanted to make sure that these bikes were available to purchase for any rider who had their heart set on a preferred model and wanted to secure theirs well in advance.
The dates listed are as accurate as possible, but please note that the entire manufacturing world is in the middle of a global supply chain challenge. As a result, there are some variables that are out of our control (like container shortages, port delays, and the Suez Canal incident).
We know how excited you are to get your new ebike and we are continually scaling up our operations to get it to you as soon as possible.
