UDITER is an up-and-coming eSkateboard brand that sells both hub motor and belt motor options in the longboard category. You can learn a bit more about them below, highlighted from their website.
Through two and a half years of research and development, my team and I have finally completed the design and production of the super electric skateboard which I had in mind, and we have set up a manufacturing facility. We now have warehouses in both Los Angeles and New York with a UDITER customer service center in Florida. My team and I will provide you with satisfactory products and services.
This electric longboard shines because if you took away the electronics you'd still have a well-built and fun-to-ride longboard left over. It's smooth, stable, and an absolute blast to carve on! The remote is easy to use with multiple riding modes and perfectly tuned acceleration & braking responses, and the S3 includes two quick-swappable batteries so you can get up to 50 miles of riding in a single day... if your feet can handle it!
