2021 was our first year in production (what we can Gen1) and we only made a handful of these 250W bikes as a test. The UU250 would be a regular feature the following model year.
All Gen 1 bikes have a black motor/controller connection and no Axle Adjusters. Additionally, Gen 1 bikes came with Zoom Brakes, Maxxis Hook Worm Tires, and a small (LCD4) Display.
