I sent an email to Lectric inquiring about re-registering a bike and the hydraulic brake upgrade. Below is there reply. They responded within a couple of hours. Great customer service.
Thanks for reaching out!
We do not have a way to re-register the bikes through us, but the hydraulic kit will be an option for all riders, including ones that purchased the bike used.
Within the next 30-45 days, we will send a link to current XP 3.0 riders where they can request a hydraulic brake kit for themselves, and the cost of the kit will be on us!
We will also provide installation instructions. You are welcome to take it to a bike shop for an installation, however, we are unable to cover third-party installation costs.
We are excited to be able to upgrade your 3.0 in this way! Feel free to inquire about anything else, we are happy to help.
