Blitzart board in NYC for about 2 months, 100+ miles and it is a solid board. Riding in NYC has its challenges and I feel it when riding. Going over rough terrain the motor skips, and you feel the vibration through the board. From block to block, the acceleration is a bit slow, you don't notice this until you have to start and stop at each light.
When you travel long distances, over 3 miles, I could use a bit more power. Tornado Electric Longboard has a 3-month limited warranty. Any defects due to workmanship to the motor, battery and internal electronics are covered by this warranty. The warranty does not cover user damage. Extended warranty is also available. At $279 MSRP, it is a great board, for beginners. I'm ready to step it up and most people will want to after 100 miles.
For kids, this is a great board.
Specs: TORNADO Electric Longboards - Orange
With my weight 160 pounds, the board does about 17 and close to 10 miles.
I am looking to review and demo boards if interested in sending me a board to review, please reach out.
