The Mellow Drive is one of the coolest electric longboard/skateboard products on the market at the moment. What it does is allow you to turn any old board into an electric board. Specs wise, it’ll get you 15km of range on a single charge and a max speed of 25mph! It has a super simple battery swap mechanism so you can keep your rides going and going. Mellow says it is 100% sealed against intrusion of water and dust, which is unheard of in the industry at the moment. To top it all off, they will give you a 2-year warranty. That’s the longest warranty period of all of the best electric longboard and skateboard companies at the moment.
There’s no other board or in this case, DIY kit, that I am more excited about.
