Below is a list of options you may find helpful in building your dream e-bike. I have personally installed all of these models and feel confident in endorsing any one of them. These are just recommendations. All items listed here are Amazon affiliate links. We do make a small commission if you purchase from them. Again, these are just recommendations. Where you purchase your kit and or parts from is entirely the customer. Always save your warranty on everything you buy. We offer a lifetime guarantee for the application of the kit, battery, and wiring. If anything comes loose through no fault of your own, we will fix it for you.  This includes any upgrades or replacement for parts. However, this does not include parts that fail due to the distributor. The warranty for parts is only for the parts themselves, not for removing and replacing them. Please check out our Q&A section at the link below to answer any other questions you may have. Feel free to e-mail or call us to get started today!
